  • Method and apparatus for improved routing in connectionless networks
    Patent number: 7398438
    Abstract: The invention includes a method and apparatus for determining a routing table for use in a network comprising a plurality of type-one nodes and a plurality of type-two nodes where the type-two nodes use respective type-two routing tables having one next-hop node associated with each of a plurality of destination nodes of the network. The method includes obtaining, from the type-one nodes and the type-two nodes, link status information associated with each of a plurality of links of the network, obtaining traffic measurement information from the type-one nodes and the type-two nodes, and determining, using the link status and traffic measurement information, type-one routing tables for the respective type-one nodes. The type-one routing tables are determined as a group in a substantially coordinated manner, and each type one routing table includes a plurality of next-hop nodes associated with each of the destination nodes.
