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.

A method, system and computer program product for routing packets. A network device, e.g., router, may comprise a switch fabric coupled to a plurality of blades where each blade may comprise one or more network processors coupled to one or more physical ports. The physical ports may be connected to another one or more network devices. A plurality of physical ports across one or more blades connected to the same network device may be logically mapped into a logical interface to that network device. By logically grouping a plurality of physical ports into a logical interface to a network device, a network processor may be able to transmit packets of data to that network device across multiple ports instead of one physical port.
