Abstract:
A method for delivering a datagram across a plurality of inter-network servers from a source device having a first network level protocol to a destination device having a second network level protocol, said datagram includes a transport priority defined by said first and second network level protocols, said method comprising:identifying either said source port or said destination port; determining said transport priority of said datagram from a transport priority designation of said identified source port or from a transport priority designation of said identified destination port, wherein said determining further includes determining an inter-network connection from said source device to said destination device according to said identified source port or said identified destination port; and identifying said transport priority of said datagram from said determined inter-network connection; determining a device type in accordance with an inter-network connection; determining a current server capacity of each of said plurality of inter-network servers; determining a server eligibility for each of said plurality of inter-network servers based on said determined current server capacity and said determined transport priority, wherein said determining further includes; associating said device type with said inter-network connection in a first table; associating said device type with one or more of said plurality of inter-network servers in a second table; and selecting one of plurality of inter-network servers in reference to said second table; and dispatching said datagram to one of said plurality of inter-network servers according to said determined server eligibility.
