Alcatel OmniSwitch 7000 Series

Carrier-Class Availability

Today’s successful business needs to have a network that can deliver continuous operation and

provide carrier class availability to support the demands of IP Communications and mission-

critical applications. Carrier-class availability ensures that users have access to resources and

services at all times. To ensure availability, the OmniSwitch 7000s have been designed with a

distributed architecture enabling carrier-class features, including full redundancy and resiliency.

A unique feature of the OmniSwitch 7000 series is

smart continuous switching, which provides

continuous operation in the event of a failure. With smart continuous switching, all source learning,

Spanning Tree functions, and established routes are distributed throughout the network interface

modules instead of a central engine. In the event of a management module failure, the system

automatically switches over to the hot standby module with no loss of connections or fabric

capacity. Existing L2/L3 traffic, including voice conversations, will continue seamlessly without

interruption. Plus, Alcatel’s OmniSwitch 7000s are capable of creating new connections during this

failover – an industry first.

Network resiliency is a critical part of network availability and the OmniSwitch 7000s provide

extensive support including advanced routing redundancy protocols, load sharing, and mechanisms

for fast reconfiguration of links between switches, servers, and other network devices. The

OmniSwitch 7000s provide fully redundant and resilient system components to ensure continuous

operation. This includes:

• Redundant chassis subsystems

• Hot swappable modules

• Load-sharing components

• "Hitless loading" of optional software, such as advanced routing, without re-booting

• Downloadable bootstrap

• Image rollback to automatically re-load previous configurations and software versions

Alcatel’s OmniSwitch 7000s are leading the industry, delivering carrier-class availability and

functionality – all at an enterprise price.
