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： Method and apparatus for implementing use of a network connection table. In one aspect, searching for network connections includes receiving a packet, and zeroing particular fields of connection information from the packet if a new connection is to be established. The connection information is converted to an address for a location in a direct table using a table access process. The direct table stores patterns and reference information for new and existing connections. The connection information is compared with at least one pattern stored in the direct table at the address to find reference information for the received packet.

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 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 system and method in accordance with the present invention allows for an adapter to be utilized in a server environment that can accommodate both a 10 G and a 1 G source utilizing the same pins. This is accomplished through the use of a high speed serializer/deserializer (high speed serdes) which can accommodate both data sources. The high speed serdes allows for the use of a relatively low reference clock speed on the NIC to provide the proper clocking of the data sources and also allows for different modes to be set to accommodate the different data sources. Finally the system allows for the adapter to use the same pins for multiple data sources.
摘要翻译：根据本发明的系统和方法允许在可以使用相同引脚容纳10G和1G源的服务器环境中使用适配器。这是通过使用可以容纳两个数据源的高速串行器/解串器（高速serdes）来实现的。高速serdes允许在NIC上使用相对较低的参考时钟速度来提供数据源的适当时钟，并且还允许设置不同的模式以适应不同的数据源。最后，该系统允许适配器为多个数据源使用相同的引脚。

摘要： A system and method for computing a blind checksum includes a host Ethernet adapter (HEA) with a system for receiving a packet. The system determines whether or not the packet is in Internet protocol version four (IPv4). If the packet is not in IPv4, the system computes the checksum of the packet. If the packet is in IPv4, the system determines whether the packet is in transmission control protocol (TCP) or user datagram protocol (UDP). If the packet is not in either of TCP or UDP the system attaches a pseudo-header to the packet and computes the checksum of the packet based on the pseudo-header and the IPv4 standard.
