White Paper Abstract:
Mobile IP has increasingly become important in the public safety and public transportation markets. Customers in those markets are likely to adopt multiple wireless technologies to support their mission-critical applications and new services. Before the introduction of the Mobile IP—Mobile Router Multipath Support feature, the Cisco implementation of Mobile IP supported only one tunnel between the mobile router and the home agent. Because of this implementation, only one tunnel and one wireless technology could be used at a given time. This feature provides support for multiple paths, and thus multiple wireless technologies, between the mobile router and the home agent and allows user traffic to be load-balanced over all available interfaces.
This white paper discusses details regarding multipath support in mobile routers and mobile IP.
