摘要： Translating between an Ethernet protocol used by a first network component and a Converged Enhanced Ethernet (CEE) protocol used by a second network component, the first and second components coupled through a CEE Converter that translates by: for data flow from the first network component to the second network component: receiving, by the CEE converter, traffic flow definition parameters for a single CEE protocol data flow; calculating, by a credit manager, available buffer space in an outbound frame buffer of the CEE converter for the data flow; communicating, by the credit manager to a CEE credit driver of the first component, the calculated size of the buffer space together with a start sequence number and a flow identifier; and responding, by the CEE credit driver to the CEE converter, with Ethernet frames comprising a private header that includes the flow identifier and a sequence number.

摘要： Systems and methods to communicate data frames are provided. A particular apparatus may include a first adapter having a first queue configured to store a data frame associated with a first priority. The adapter is configured to generate a first priority pause frame. A distributed virtual bridge may be coupled to the first adapter. The distributed virtual bridge may include an integrated switch router and a first transport layer module configured to provide a frame-based interface to the integrated switch router. The transport layer module may include a first buffer associated with the first priority. A first bridge element of the distributed virtual bridge may be coupled to the first adapter queue and to the first transport layer module. The first bridge element is configured to receive the first priority pause frame from the adapter and to communicate an interrupt signal to the first transport layer module to interrupt delivery of the data frame to the first queue.

摘要： An assignment constraint matrix method and apparatus used in assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device. The assignment constraint matrix is implemented as a plurality of qualifier matrixes adapted to operate simultaneously in parallel. Each of the plurality of qualifier matrixes is adapted to determine sources in a subset of supported sources that are qualified to provide work to a set of sinks based on assignment constraints. The determination of qualified sources may be based sink availability information that may be provided for a set of sinks on a single chip or distributed on multiple chips.

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： An addressing model is provided where all resources, including memory and devices, are addressed with internet protocol (IP) addresses. A task, such as an application, may be assigned a range of IP addresses rather than an effective address range. Thus, a processing element, such as an I/O adapter or even a printer, for example, may also be addressed using IP addresses without the need for library calls, device drivers, pinning memory, and so forth. This addressing model also provides full virtualization of resources across an IP interconnect, allowing a process to access an I/O device across a network.

摘要： A technique is provided to delete a leaf from a Patricia tree having a direct table and a plurality of PSCB's which decode portions of the pattern of a leaf in the tree without shutting down the functioning of the tree. A leaf having a pattern is identified as a leaf to be deleted. Using the pattern, the tree is walked to identify the location of the leaf to be deleted. The leaf to be deleted is identified and deleted, and any relevant PSCB modified, if necessary. The technique also is applicable to deleting a prefix of a prefix.

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.

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.
