  • Digital telecommunication link for efficiently transporting mixed classes of packets
    Patent number: 5497371
    Abstract: An efficient packet transport system for mixed traffic in which a packet fragmentation protocol allows traffic of different classes to occupy a single physical link. In one embodiment, packet fragmentation gives delay sensitive traffic priority over non-sensitive traffic. This allows both traffic types to coexist on a single data link. The protocol eliminates software overheads associated with mis-ordered packets and efficiently transports both cell and frame formatted data using encapsulation.
