MANET: Enhancements to PPPoE for Router-to-Radio Links


The MANET: Enhancements to PPPoE for Router-to-Radio Links feature extends Point-to-Point Protocol over Ethernet (PPPoE) to enable a router or radio to query or report link-quality metric information. Credit-based flow control provides in-band and out-of-band credit grants in each direction. Link quality metrics are used to report link performance statistics that are then used to influence routing.

Mobile Ad Hoc Networks (MANET) for router-to-radio communications address the challenges faced when merging IP routing and mobile radio communications in ad hoc networking applications. the Cisco solution for MANETs provides capabilities that enable

Optimal route selection based on Layer 2 feedback from the radio network

Faster convergence when nodes join and leave the network

Efficient integration of point-to-point, directional radio topologies with multi hop routing

Flow-controlled communications between each radio and its partner router

Through the router-to-radio link, the radio can inform the router immediately when a node joins or leaves, and this enables the router to recognize topology changes more quickly than if it had to rely on timers. Without this link-status notification from the radio, the router would likely time out while waiting for traffic. The link-status notification from the radio enables the router to respond faster to network topology changes. Metric information regarding the quality of a link is passed between the router and radio, enabling the router to more intelligently decide on which link to use.
