摘要： System and method for maintenance and examination of timers for a computer system having connections in a networking system. Timer values in a connection table each indicate a timeout for a timer for a connection, where each connection has multiple timers, and one of the timer values is written to a global timer array for each connection such that the global timer array can be scanned to determine when timeouts occur for active connections. Sparse restart of a timer includes restarting the timer if data is communicated with a connected computer before the timeout occurs and after a predetermined time interval after timer start, and not restarting the timer if data is communicated before the timeout occurs and within the predetermined interval after timer start.

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.
摘要翻译：一种用于处理TCP / IP数据包的方法，计算机程序产品和系统。 TCP协议栈可以将接收到的TCP / IP分组的有效载荷存储在数据片段列表中。 TCP协议栈可以进一步读取接收到的分组的报头，以将用于索引的值提取到存储传输控制块（TCB）列表的表中。 TCP协议栈还可以对表中索引的TCB进行锁定和读取操作。 TCP协议栈可以进一步将有效负载传输到TCP应用，而不需要应用程序对索引的TCB执行锁定，读取，写入或解锁操作，因为TCP协议栈和TCP应用程序在相同的线程上运行。通过TCP应用程序对TCB进行锁定，读取，写入和解锁操作，存储器访问次数减少。

摘要： A system and method for transmitting data from a first site to a second site over a shared Multi-Protocol Label Switched (MPLS) network comprising a plurality of routers, including an ingress router in communication with the first site and an egress router in communication with the second site, includes configuring a plurality of label switching paths between the ingress router and the egress router over a plurality of label switching devices. The method further includes performing a first lookup on one of at least one virtual routing and forwarding (VRF) table stored in the ingress router, whereby the first lookup identifies one routing table from a plurality of routing tables stored in the ingress router, each routing table being associated with one of the plurality of label switched paths, and performing a second lookup on the one routing table, wherein the routing table defines the associated label switched path between the ingress router and the egress router for a virtual private network (VPN) between the first site and the second site.

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.
