Administrative Weight and Parallel Routes

A route’s administrative weight defines its desirability to the PNNI routing service with regard to computing a path to a particular location. The lower the administrative weight, the more desirable the route. For example, a route with administrative weight 200 is considered a better route than one with the default weight of 5040. As a result, the administrative weight provides a quantitative way to control which routes are favored for call set up.

The ability to control the PNNI routing service in this fashion allows for parallel routes into an IISP domain to be weighted such that one route is designated as the default, while the other becomes the backup route. This default/backup routing topology is typically used where a link to a particular domain requires a high degree of reliability. If the default route becomes congested or reaches its bandwidth limit, the routing service can initiate load sharing by routing additional calls through the backup route.

4.3IP ROUTING

The SmartCell 6A000 switch provides limited IP routing. IP routing allows switches that are not connected directly to Ethernet to communicate with an Ethernet-based network management system (NMS). The connection is made by adding IP routes on the non-connected switches that specify a client on a connected switch as their gateway to the Ethernet.
