Your need to distribute the core of your network may be driven by any of a number of reasons — connecting a campus, providing disaster recovery, uniting disparate departments, providing services in an MxU environment. Whatever the driver, distributed network core solutions will always require high performance and high availability, without adding unnecessary layers of complexity to the network or its management.
Allied Telesis Ethernet Protection Switched Ring (EPSRing) solutions provide high performance, high reliability, flexible, scalable distributed network cores. The core can be as small or as large as you need. It can be 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.
