    摘要： Methods and apparatus are provided for alternative routing of a connection between a source node and a destination node in a PNNI hierarchical network. The alternative routing method comprises responding to a failed connection between said nodes due to a sole-access element of the network structure as seen by the source node, where a said sole-access element is an element which provides sole access to the destination node in said network structure, by: selecting at least one non-sole-access element of the route used by the failed connection in said network structure; identifying an alternative route for the connection in said network structure which does not utilize the at least one selected element; and using the alternative route for establishment of the connection between said nodes.

    摘要： A mechanism is provided for sharing a communication used by a parser (parser path) in a network adapter of a network processor for sending requests for a process to be executed by an external coprocessor. The parser path is shared by processors of the network processor (software path) to send requests to the external processor. The mechanism uses for the software path a request mailbox comprising a control address and a data field accessed by MMIO for sending two types of messages, one message type to read or write resources and one message type to trigger an external process in the coprocessor and a response mailbox for receiving response from the external coprocessor comprising a data field and a flag field. The other processors of the network poll the flag until set and get the coprocessor result in the data field.

    摘要： A method for oversubscribing bandwidth in a communication network, is disclosed. The method includes policing a first data flow and outputting a first output data flow from the first meter, in relation to a first Committed Information Rate (CIR) and a first Peak Information Rate (PIR); policing a second data flow and outputting a second output data flow from the second meter in relation to a second CIR and a second PIR; and policing an aggregated output data flow of the first output data flow and the second output data through a third meter of the oversubscription module, where the aggregated output data flow is policed in relation to a third CIR and a third PIR.

    摘要： A method, computer program product and system for processing TCP/IP packets. A TCP protocol stack may store a payload of a received TCP/IP packet in a data fragment list. The TCP protocol stack may further read the header of the received packet to extract a value used to index into a table storing a list of transport control blocks (TCBs). The TCP protocol stack may further perform a lock and a read operation on the TCB indexed in the table. The TCP protocol stack may further transmit the payload to the TCP application without requiring the application to perform a lock, read, write or unlock operation on the indexed TCB since the TCP protocol stack and the TCP application are operating on the same thread. By the TCP application foregoing the lock, read, write and unlock operations on the TCB, there is a reduction in the number of memory accesses.
