    摘要: The present invention establishes a circuit emulation service (CES) over an internet protocol (IP) network based on properties of the IP network. The CES emulates a circuit from a local interworking function to a remote interworking function. Data that is received at a constant bit rate at the local interworking function is encapsulated into a number of IP packets configured according to the CES. The IP packets are transported from the local interworking function to the remote interworking function according to the CES. In one embodiment, each IP packet also includes data segments for simultaneously encapsulating multiple constant bit rate circuits. In another embodiment, each data segment includes a separate CES circuit header.

    摘要: An apparatus is described having an output packet organizer that has a first location and a plurality of second locations. The first and second locations correspond to the priority of a packet, where the first location has higher priority than the second locations. The output packet organizer has a third location. The third location has a higher priority than the first location. The first and third locations are coupled to a scheduler that serves the first and third locations. The second locations coupled to the scheduler through a round robin pointer.

    摘要: A method is described that involves presenting packet header information from a packet and packet size information for the packet to a pipeline that comprises multiple stages. One of the stages identifies, with the packet header information, where input flow information for the packet is located. The input flow information is then fetched. The input flow information identifies where input capacity information for the packet is located and the input capacity information is then fetched. Another of the stages compares an input capacity for the packet with the packet's size and indicates whether the packet is conforming or non-conforming based upon the comparison. The input capacity is calculated from the input capacity information.

    摘要: An apparatus having a pipeline having a series of stages. At least one of the pipeline stages has a first interface for coupling to a memory that stores output capacity information for a packet. The output capacity information is obtainable from the packet's packet header information or internal information where the internal information is used within a service provider's network. At least one of the pipeline stages has a second interface that receives packet size information; a third interface that receives the output capacity information; and comparison logic coupled to the second and third interfaces. A method that involves presenting packet header information and packet size information to one or more pipeline stages where the packet header information and the packet size information correspond to a packet. Then, determining within a stage associated with the pipeline, with the packet header information, output capacity for the packet. Then, comparing within a stage associated with the pipeline, the output capacity with the packet size to determine appropriate delay for the packet.

    摘要: A micro-programmable controller is disclosed for parsing a packet and encapsulating data to form a packet. The micro-programmable controller loads an instruction within the micro-controller. The instruction word has a plurality of instruction fields. The micro-controller processes the plurality of instruction fields in parallel. Each instruction field is related to a specific operation for parsing a packet or encapsulating data to form a packet. The programmable micro-controller can be programmed to handle packets to support new types of protocols by programming a template to string specific routines together based on an instruction set specific for parsing and encapsulating.
