Mehrfach-virtuelle Wegsucher

摘要

A multiple virtual router is a subsystem that allows multiple network layer protocols (i.e. IP, IPX and Bridging protocols) to co-exist on the same physical port 14. It provides a common set of interfaces between the Media Layer and the protocol processes. Media events or changes in the protocol port (i.e. port deletion, media deregistration, media registration, media state change, media mtu change, connectionless routing metric change, etc.) may be broadcast to each protocol giving them an accurate view of the system. A multiple virtual router is disclosed which includes a housing and multiple routing modules distributed therein. A separate table is associated with each protocol within each routing module. The multiple virtual router also includes a management module for configuring the routing modules. Communications between the management module and the routing modules occurs out of band from the user traffic. Further, the housing may have multiple ports each of which is logically coupleable to different routing modules.
