Abstract:
A dynamic integrated router and transport network system comprising:a logical SDH ring, the SDH ring comprising a set of access interfaces, the set of access interfaces corresponding to a set of network interfaces of a logical router, wherein a connection can be dynamically formed uni-directionally between a pair of access interfaces; a set of connections, with each connection having an associated capacity, wherein the network system dynamically adapts the capacity associated with each connection to a inbound volume of a packet flow routed via the connection between a pair of access interfaces of the SDH ring; a plurality of packet terminals coupled by the SDH ring, each of the plurality of packet terminals comprising one or more access interfaces and one or more SDH ring interfaces for transceiving the plurality of packet flows between the other packet terminals coupled with the SDH ring, the set of access interfaces of the plurality of packet terminals coupled with the SDH ring serving as the access interfaces of the SDH ring, and wherein there is one active master connection controller controlling the packet terminals coupled with the SDH ring; wherein the active master connection controller periodically receives a set of packet terminal reports, one report from each of the packet terminals on the SDH ring, the reports indicating the inbound volumes associated with the plurality of packet flows routed over the SDH ring between the access interfaces of the packet terminals on the SDH ring, and in response thereto, the active master connection controller provides a set of connection map instructions to the packet terminals on the SDH ring for dynamically adapting the capacity of each of the connections in the SDH ring to the actual volumes of the packet flows associated with the connections.
