Abstract:
A method of communicating connectionless datagrams between a source node and a destination node over a connection-oriented network, said method comprising the steps of:transmitting from said source node to a connection request server coupled to said connection-oriented network a connectionless address of said destination node to signal a request to communicate with said destination node;in response to said request received by said connection request server, establishing from said connection request server a connection-oriented virtual channel between said source node and said destination node using third-party control;assigning a virtual channel identifier to said connection oriented virtual channel;transmitting said virtual channel identifier from said connection request server to said source node;segmenting said connectionless datagrams into one or more appropriate size connection-oriented cells, each of said cells including said virtual channel identifier; andtransmitting said one or more cells from said source node to said destination node on said connection-oriented virtual channel.
