Key Solution - Ethernet Protection Switching Ring (EPSR)

EPSR - Resiliency and Fault Tolerance

The increased convergence of services and applications in the enterprise has led to increasing demand for highly available networks with minimal downtime.

High bandwidth is also required for the multiple applications simultaneously using the network. Real-time applications like surveillance, video streaming and voice

over IP (VoIP) are used right alongside data and Internet access.

When you want a high-performing, resilient network for your enterprise core, using EPSR with the Allied Telesis SwitchBlade x908 and x900 series switches

provides the ideal solution. EPSR creates a high-speed resilient ring that can utilize today's maximum Ethernet standard of 10Gbps, and provide extremely fast

failover between nodes. EPSR enables rings to recover within as little as 50ms, preventing a node or link failure from affecting customer experience, even with

demanding applications such as IP telephony and video monitoring.

The below diagram shows a corporate network based on a central EPSR ring. The inclusion of Allied Telesis Virtual Chassis Stacking (VCStack) technology at the

core of the network adds a further layer of resiliency, increasing the availability of critical resources.

Now that technology has made high-availability and high-bandwidth so accessible; corporate business, education providers and other enterprise network users

can enjoy the benefits that EPSR has to offer. By ensuring always-available online applications and resources, this advanced self-healing network technology meets

the insatiable demand for information at the fingertips.
