Abstract:
1. A communication network, comprising a plurality of cell-based routers; a plurality of frame-based routers; and a bidirectional cell and frame based switch coupled to the cell-based routers and frame-based routers for transmitting VoIP traffic in a bi-directional manner among the cell-based and frame-based routers, wherein each of the cell-based routers is provisioned with a transport rate of at least one of the frame-based routers, and wherein each of the cell-based routers is programmed to: reshape traffic bandwidth by adjusting cell transmission rate to avoid packet losses at the frame-based routers, wherein the cell transmission rates for each of the cell-based routers is adjusted based on the provisioned transport rate of the frame-based router, wherein each of the cell-based routers adjusts the cell transmission rate by buffering data cells; and route cell-based traffic to the bidirectional cell and frame based switch according to the updated bandwidth.
