    摘要: Packet switching node in a communication system includes apparatus for receiving incoming information packets or frames which contain header portions with formatting control blocks. Information in the frame's header contains frame alteration commands for modifying the information in the frame. The modifications include adding new information, deleting information, and overlaying information. Decoders and control devices in an alteration engine interpret the commands and apply the modifications to the frame data. Common and standard data patterns are stored for insertion or overlaying to conserve data packet space.

    摘要: A method, system and computer program product for translating a type of service field of one protocol into multiple protocols. An ingress router in a DIFFerentiated SERVices network (Diffserv over MPLS network) may determine a type of quality of service, e.g., forward IP packet using best effort. A value referred to as a Per Hope Behavior (PHB) value may be generated based on the identified type of quality of service. The PHB value may be used to index into a table comprising a row of entries with different quality of service values, e.g., DSCP value, EXP value, corresponding to a particular PHB value. Consequently, the PHB value may be used to perform a single memory access to determine the quality of service values for a plurality of protocols where the quality of service values corresponds to the identified type of quality of service.
