Core Network Solutions

A reliable network core is of paramount importance to every organization—whether a large healthcare facility or mission-critical defense installation. The key to achieving reliability and high network uptime is for resilience to be a primary requirement when the network is being designed.

When designing a network, it is important to accept that neither equipment nor people are flawless. Even the most expensive equipment and the largest, most specialized IT team cannot eliminate the potential for network faults that result in downtime.

Greater value can be gained from intelligent network design that increases the level of resilience within the network and eliminates single points of failure. While faults and operational errors can occur, the design goal should be to create a network that will withstand such events.

Increasing the level of resilience within the network starts at the core of the network. Eliminating single points of failure at the edge of the network will be of little value if the network core remains vulnerable. Allied Telesis network solutions deliver technology that enables highly available, resilient networks to be implemented and can extend that resilience all the way to the edge of the network—enabling single points of failure to be eliminated while delivering the greatest return on networking investment.

Allied Telesis Virtual Chassis Stacking Plus (VCStack Plus)

Watch this video to learn about how VCStack Plus™ creates a single virtual unit out of two SwitchBlade chassis. As each chassis has dual control cards, and dual power supplies, you get the full power and reliability of a real chassis — times two! VCStack Plus provides quad resilience for complete network availability.

Ethernet Protection Switched Ring (EPSRing)


Allied Telesis EPSRing solutions provide high performance, high reliability, flexible, scalable distributed network cores. The core can be as small or as large as is needed, connected by copper or fiber, or even copper and fiber in the same ring. The core bandwidth can be anything from 100Mbps to multiples of 10Gbps. The recovery time when links or nodes go down is extremely fast — as low as 50 ms, making this solution ideal for the provision of converged voice, video and data services.

Virtual Chassis Stacking (VCStack)


Using Allied Telesis VCStack™ in a network allows multiple switches to appear as a single virtual chassis. VCStack and link aggregation provide a solution where network resources are spread across the virtual chassis members, ensuring device and path resiliency. Virtualization of the network core ensures uninterrupted access to information when needed.

Virtual Chassis Stacking (VCStack Plus)

VCStack Plus

Allied Telesis VCStack Plus allows two switches to combine as a single virtual unit. You get the full power and reliability of a chassis switch – times two. VCStack Plus provides a solution with complete resiliency and no single point of failure. With fiber stacking connectivity, the two chassis can even be distributed over long distance.
