Allied Telesis offers versatile, highly resilient 10 Gigabit connections for the most advanced and

demanding of enterprise, service provider and municipal networks. Capabilities include carrier-grade

modular and chassis-based switching and access solutions that provide Ethernet Protected Switched

Rings with sub 50ms failover for mission-critical services.

Switches

Ethernet Protected Switched Rings (EPSR)

Putting a ring of Ethernet switches at the core of a network is a

simple way to increase the network’s resilience — such a network

is no longer susceptible to a single point of failure. Traditionally,

Spanning Tree-based technologies are used to protect rings, but

they are relatively slow to recover from link failure. This can create

problems for applications that have strict loss requirements, such

as voice and video trafc, where the speed of recovery is highly

signicant. EPSR provides high-speed (<50ms) recongurations in

the event of a failure, ensuring no noticeable loss of service in these

types of installations.

Dual Core Networking

Traditional core switches provide resilience by having one chassis

actively running, while a second sits in standby. Users therefore pay

for two chassis, but only achieve the throughput and performance

of a single chassis. Allied Telesis switches with VCStack virtual

chassis stacking allow both core switches to pass trafc actively, with

one also being the backup in the event of a failure. Thus for the

majority of the time, users benet from twice the performance of a

traditional core network.
