Supporting IoT Initiatives and Distance Learning

Educational institutions are integrating more smart Internet of Things (IoT) into their educational networks. IDC predicts that in 2025 there will be more than 40 billion connected devices. Implementing IoT in the classroom is no longer just about internet accessibility, it’s about extending connectivity beyond traditional smart devices to engage students, create immersive learning experiences, and solve common challenges.Now that distance learning has been pushed to the forefront, IoT has become even more important. The integration of distance learning into digital curriculums has increased the need for constant connectivity so that faculty and students are able to interact through digital forms of communication. Learning management systems, such as Blackboard, video calls, and discussion boards are all critical for distance learning, solely done online they require always-on access.

Managing an IoT system in this environment involves the use of alternate connectivity and dedicated management devices that provide resilient access at the edge of the infrastructure. These devices require continuous monitoring, configuration, provisioning, and remediation to provide resilience.

Provisioning New Campuses

Educational institutions are constantly expanding with some facilities that can be located across the country. The Secure Provisioning NetOps module by Opengear enables engineers at these schools to ship equipment to new locations and provision it remotely, eliminating the need for highly skilled engineers on site.

Automating the initial provisioning, configuration management and disaster recovery of remote infrastructure, an Opengear appliance is incorporated into the initial rack shipped to the location, once powered on, it calls home over the embedded cellular module. TPM safeguards are embedded into the unit to ensure that the firmware, configurations, and authentication keys haven’t been tampered with prior to installation. Lighthouse Enterprise automatically pushes image, configuration, and script files to the device which then provisions other hardware at the location. Providing secure Zero Touch Provisioning to the entire local infrastructure from one appliance, the need for human interaction is eliminated, saving educational institutions resources.

Opengear Case Study – Keeping i3D.NET Undefeated By Downtime

Secure, Resilient Access and Automation to IT infrastructure

Opengear Case Study – Keeping i3D.NET Undefeated By Downtime

Opengear Solutions for Network Resilience

Ensuring network resilience is an important business priority for i3D.net. To maintain its global operation, i3D.net runs a complex low-latency network, with thousands of servers spread over more than 35 points of presence on 6 continents.

It is key that this network is kept up and running at all times. As Rick Sloot, chief operations officer, i3D.net explains: “Ten years ago, this was very difficult to achieve. There were very few ways of handling and managing your servers when the internet went down and those that were available were expensive and did not work well. As technology has advanced over the past decade, customer expectations have grown in line, and a high level of network resilience is now demanded by our users.

As we expanded as a business, opening up new locations around the world, it was becoming increasingly difficult to find a vendor capable of delivering a reliable way of keeping us up and running at all times, across all our locations.” continued Sloot.

We struggled to find local vendors who could support us. Often, we weren’t able to pinpoint the issue or access the faulty equipment. We needed to find a way of managing equipment remotely, identifying and resolving the problem, while keeping the network online. We started to look for a vendor who could work with cellular technologies such as 4G and who could deliver out-of-band management. Opengear fitted the bill perfectly. Opengear’s tools can support 4G cellular out-of-band connections in all our global locations which have enabled us to save time and money. We were looking for a partner that could deliver triple-A equipment on time all over the globe and knew we could rely on Opengear for this.

i3D.net is a leading provider of high-performance hosting and global infrastructure services. The company notably excels in-game hosting and infrastructure, serving 100 million gamers daily for game publishers and independent developers on consoles, PC and mobile. The i3D.net network is one of the world’s top-10 most connected hosting provider networks. i3D.net is now a Ubisoft company, having been bought by the French publisher in 2018.

Original case study at Opengear web pages: Keeping i3D.NET Undefeated By Downtime

i3D.net decided to work in partnership with Opengear and implement its ACM 7008-2-L Resilience Gateway to provide smart out-of-band management to its entire IT infrastructure, and also to provide a built-in backup LAN and/or backup Internet connectivity option for all their remote sites.

Reaping the Rewards

Today, i3D.net uses the Opengear Resilience Gateway as a fall-back, providing out-of-band management, as and when required, to its routers all over the world. It has achieved a raft of benefits as a result. For example, it has helped to significantly streamline the process of bringing new sites online.

In the past, when i3D.net had to carry out a deployment outside the Netherlands, a technical operations engineer flew to the location and installed the new switches but would typically struggle to configure them. Today, i3D.net simply connects the Opengear Resilience Gateways to these network switches and its network operations engineers back in the Netherlands are then able to configure the whole site remotely via the Opengear device. “This is very powerful and a huge benefit for us in terms of the time and costs saved not only in provisioning but also ongoing maintenance” commented Sloot.

“We were looking for a partner that could deliver triple-A equipment on time all over the globe and knew we could rely on Opengear for this.”

Using Opengear Resilience Gateways also allows i3D.net to stay one step ahead of any pending network failures. According to Sloot: “We don’t like downtime and neither do our customers. Today, if there is an issue, we can directly connect to our routers anywhere in the world without having to wait for someone at the locations to access and fix it. The agility of the Opengear solutions means we can quickly help our customers and maintain our high standards as a performance hosting company.

Looking Ahead

Today, i3D.net continues to expand and open global locations dynamically. It is also in the process of switching to a new Juniper Networks router platform. As Sloot explains: “This will give us the opportunity to launch our Global Low-latency Anti-DDoS solution (GLAD). Every region where we are changing the router and do not have an Opengear Resilience Gateway will now receive one.

Finally, we have an enterprise customer for which we are remotely managing servers, running routers and firewalls in their own environment. We are planning to place the Opengear solution there. It marks the first time we have carried out a deployment of Opengear’s Resilience Gateway outside our own data centres.

The rapidly expanding use of Opengear at i3D.net bears witness to the broad benefits it brings the hosting provider and also highlights a partnership that goes from strength to strength today and will look to evolve further in the future. i3D.net is on a fast growth path and Opengear continues to support its dynamic expansion worldwide.

ePlus Leverages Opengear’s Smart Out-of-Band Technology

Secure, Resilient Access and Automation to IT infrastructure

ePlus Leverages Opengear’s Smart Out-of-Band Technology

The Challenge

As a leading consultative technology solutions provider with lifecycle services expertise across key areas including security, cloud, data center, collaboration, networking and emerging technologies, ePlus allows its customers to achieve positive business outcomes through the use of transformative technology. For ePlus, ensuring seamless network connectivity for business continuity across its 38 U.S.-based office locations and two data centers was absolutely critical.

Prior to adopting Opengear in 2016, ePlus used POTs lines with external modems plugged into auxiliary ports for OOB. According to Chris Smolen, Manager of Network Engineering for ePlus Internal IT, this solution was inefficient. Since it relied heavily on external modems, it also necessitated local, onsite involvement and maintenance, creating an inability to troubleshoot issues remotely. With so many individual locations, moving away from POTs lines became vital.

The Solution

ePlus was looking for high availability, even if the primary in-band network failed. After looking at several serial console manufacturers, ePlus selected Opengear as the ideal solution for always-on connectivity, as well as permanent monitoring, and remote management of critical IT infrastructures in its offices and data centers. A major factor was the integrated 4G solution to ensure reliable cellular access to devices.

OOB solution with high-speed failover to cellular

ePlus replaced the POTs lines and external modems with Opengear Resilience Gateways (ACM 7008-LMV with 8 ports), using Verizon 4G LTE at its branch offices across the U.S. These units are compact and ideal for small remote sites. ePlus has also expanded its deployment of Opengear to its data centers and uses the IM7248-LMV for remote access, maintenance, and proactive monitoring.

Out-of-band management minimizes maintenance costs

The integrated wireless option offered by the OOB console servers also allows ePlus to substantially reduce costs involved with traveling to its remote offices to perform routine maintenance tasks, such as firmware updates, patches and other configuration changes, providing it with a bigger return on investment.

Opengear’s Smart Out-of-Band allows IT staff to manage the infrastructure of hundreds of sites and thousands of devices with advanced troubleshooting and remediation from one centralized console, reducing operating costs and minimizing downtime.

Centralized management of the OOB infrastructure

ePlus also wanted its out-of-band solution to offer a centralized management system with automatic configuration for simple scalability and device provisioning. This software had to allow ePlus to keep an eye on all installed OOB consoles and connected devices from asingle pane of glass. ePlus opted for Opengear’s Lighthouse management software. This central management platform for remote access is a virtual software appliance and implements OpenVPN encrypted tunnels to gateways for all LAN, WAN and wireless remote access connections. Lighthouse can be installed on any VMWare session as well as cloud hosting services including Amazon’s AWS, Microsoft Azure, and Google’s GCE. Lighthouse also offers a RESTful API interface, allowing the platform to be integrated easily in other management tools already installed. Lighthouse offers a status overview of all access gateways or nodes, allowing for simple management. Nodes can be easily enrolled and the process is further simplified using enrollment bundles. These bundles combine a unique registration token with user-defined tags such as a geographical location, a department or even a rack position. Devices can also be grouped according to users, sites or manufacturers. In addition, strict access authorization can also be defined.

Out Of Band Management

Results

"The Resilience Gateway with Cellular isn’t just more reliable than our previous analog modem solution – it’s substantially more reliable.”, explains Smolen. “They work every time we need them. Opengear is always available to answer any questions, and quickly. Working with Opengear has been an excellent experience."

Chris Smolen, Manager of Network Engineering for ePlus Internal IT

Three years after adopting its new out-of-band management solution, ePlus is very pleased with the Opengear experience.

Delivering managed technology services requires fully reliable and resilient connectivity to network resources,” said Todd Rychecky, VP of Sales Americas, Opengear. “We’re glad to see how ePlus has been able to bolster its platform stability and grow its compelling service offerings in part by using Opengear’s Smart Out-of-Band solutions to deliver a more resilient network.

ePlus is a leading consultative technology solutions provider that helps customers imagine, implement, and achieve more from their technology. With the highest certifications from top technology partners and lifecycle services expertise across key areas including security, cloud, data center, collaboration, networking and emerging technologies, ePlus transforms IT from a cost center to a business enabler. Founded in 1990, ePlus has more than 1,500 associates serving a diverse set of customers in the U.S., Europe, and Asia-Pac.

5G’s Impact on Edge Computing & IoT. How will 5G enhance your cellular connectivity?

Secure, Resilient Access and Automation to IT infrastructure

5G’s Impact on Edge Computing & IoT. How will 5G enhance your cellular connectivity?

The next generation of wireless technology is here. 5G will enhance connectivity across all platforms, providing more efficient, faster and better signal strength which opens doors for new possibilities across cellular networks. It is predicted that by 2024 more than 1.5 billion devices will be connected to 5G.¹ So how will 5G enhance your cellular connectivity?

Differentiating Between 4G and 5G

5G will be a strong enabler in the expansion of the Internet of Things (IoT), given the speed and versatility it will bring to networks. 5G has a range of benefits when compared to 4G, based on its use of the 30 GHz to 300 GHz spectrum:

  • Higher speeds: 5G peak speeds, at up to10 Gigabits/s, will potentially be ten times the speed of 4G. ²
  • Lower Latency: 5G offers latency below 1ms, compared to a typical 4G performance of 10-50ms. ²
  • Greater capacity: 5G networks will have capacity for a larger number of connected devices, by some estimates as much as one million devices per square kilometer³

5G is gradually being rolled out, so later iterations are expected to have even stronger capabilities.

It’s important to note that 5G, unlike previous iterations, is not expected to replace 4G. Many applications, such as standard mobile phone calls and low-data transactions, will still be carried on a 4G network, with 5G being applied primarily to large-compute and low-latency uses.

Differentiating Between 4G and 5G
Ref: STATISTA

Given the higher frequency spectrum, 5G also requires a higher density of towers to cover a given area, meaning that rollout of 5G will initially be limited to metropolitan areas. It is also impacted more severely by physical barriers such as walls, trees, and even bad weather.

5G, IoT and the Edge

Compute locations are moving increasingly to the edge, driven by the growth of IoT and the desire to process and prioritize data closer to the collection point. Faster connections associated with 5G will support that migration as enterprises distribute their network power between Data Centers, Cloud Computing and the Edge.

The low latency and high speed of 5G particularly suit applications such as consumer VR/AR, AI, and autonomous vehicles, with high data density and rapid response requirements, enabling faster adoption of these technologies.

5G and Out-of-Band

Users expect the same level of uptime and response from their network, regardless of where that compute is located. But the reality of edge locations is that the type of system redundancy and staffing that is typical at data centers are not feasible at each location. Reliable, always-on access to the network devices, via out-of-band management, is a critical component of that network resilience.

As levels of automation continue to increase, enterprises will also have to extend the reach of their management and monitoring tools. Opengear solutions anticipate the current and future network needs of 5G.

Opengear smart solutions provide engineers at the Network Operations Center (NOC) with the ability to reach devices located at the edge. Lighthouse ensures access and visibility remotely, during critical failures while Smart Out-of-Band provides advanced troubleshooting to remediate issues that may arise at the network’s edge. The NetOps Automation platform provides additional functionality to streamline repetitive workflows such as secure provisioning and event management.

Article: Breaking down the hype: What can we expect from 5G?

Deciding When to Adopt

Each organization has a core IT infrastructure and line of business applications. Constantly improving technologies provide an opportunity to help them operate more efficiently. Once the right technologies have been identified, enterprises must identify the right moment to get on board to ensure meaningful results.

For 5G specifically, determining the right time to act requires understanding the most immediate use cases for it within the enterprise. The first is fixed internet connectivity. Instead of using cable, satellite or copper wires/ADSL, edge locations could potentially use 5G to get fixed internet connectivity. Because this eliminates the need for burdensome physical cables and wires, 5G may provide an easier method for deployment.

For many enterprises, it is too early to fully embrace 5G. Unless there are already specific applications that are limited by speed/latency of existing connectivity technologies, the value of deploying it will not yet be realized. Instead, the focus, for now, should be on understanding the technology at a high level and identifying the use cases that are likely to benefit the business most so that they can be prioritized when 5G becomes readily available.

SD-WAN Deployments Need Out-of-Band Visibility

Secure, Resilient Access and Automation to IT infrastructure

SD-WAN Deployments Need Out-of-Band Visibility

SD-WAN provides lower cost, secure network connections across corporate and regional locations, based on the simplified architecture of SDN. But without an Out-of-Band backup, SD-WAN has an Achilles heel.

Flexible Networks Across Remote Locations

SD-WAN is the application of Software Defined Networking (SDN) to create a smarter, more agile Wide Area Network, able to support the increasingly sophisticated distribution of networking devices across multiple locations and remote sites, whether that’s branch offices, manufacturing locations or retail stores. It provides the flexibility to change the network configuration and logical topology without changing the physical infrastructure, and allows the creation of virtual network groups across sites, independent of where people are geographically located.

Key benefits of SD-WAN:

  • Increased flexibility of network configuration, with reduced complexity
  • Quick deployment of new network locations using zero touch provisioning
  • Seamless management of distributed team members with Virtual Local Area Networks across multiple locations
  • Reduced cost by leveraging commodity hardware and eliminating expensive private network circuits
  • Secure connection of standard broadband via a dynamic VPN tunnel
  • Balances traffic across multiple technologies (broadband, 4G LTE) without the need for dedicated MPLS circuits
Opengear SD-WAN Deployments Need Out-of-Band Visibility

The Tale of Two SD-WAN Deployments Infographic. Click thumbnail to enlarge.

The local router is a more sophisticated device in a SD-WAN deployment, incorporating advanced software capabilities to provide a flexible configuration across the network. Moving away from the vertically integrated ecosystems of the past, these CPE routers can now be based on commodity hardware, reducing costs and expanding the available options.

Smart Out-of-Band for a Resilient SD-WAN

This new flexibility brings with it a heightened need for remote hands to manage the on-site devices. With the increased sophistication of the SD-WAN hardware – specifically the advanced routers located at each site – the need for “always-on” access to that hardware is more critical than ever. In many locations, the level of technical ability will be limited, so when an issue occurs the network team must be able to manage the equipment remotely. An out-of-band network provides that visibility and security.

Initial Implementation

During the initial roll out and migration from the previous WAN, using a console server can avoid an expensive truck roll. Ship an Opengear Resilience Gateway to site, and provision the network from a central NOC without the need to send an experienced network engineer to each location. Embedded cellular in the Opengear unit enables this process over 4G-LTE if the primary network is not available during the transition.

As with any new implementation, the first few months may be unstable with frequent updates and glitches, such as encapsulation issues disrupting connectivity. Smart out-of-band allows you to automate these updates and remediate issues without sending someone to site.

Opengear SD-WAN Resilience

Steady Operation

A benefit of SD-WAN is the ability to aggregate multiple circuits for load balancing and redundancy, but the SD-WAN router can still be a single-point-of-failure. A single event can still cause simultaneous failures in multiple circuits (for example, severed cables into the facility), if a truly separate path is not in the mix. Smart out-of-band offers Failover to CellularTM, to ensure your SD-WAN continues to operate when all other circuits are unavailable.

With an Opengear console server at every SD-WAN location, and each node part of a Lighthouse 5 Centralized Management system, NetOps staff at the Data Center or NOC can remotely manage, automate and orchestrate the network devices without the need for experienced technical staff at each site.

An out-of-band management network provides the guaranteed access and high reliability to make SD-WAN a low-risk option.

SD-WAN + Smart OOB = Secure, Flexible, Resilient Network for your Entire Enterprise
