摘要： In one embodiment, a router establishes a serial-over-TCP/IP (Transmission Control Protocol/Internet Protocol) communication session between terminal units using raw-TCP encapsulation. For the session, the router maps serial characters to TCP out-of-band (OOB) communication fields, maps serial flow control signals to TCP/IP receiver-window advertisements, and dynamically adjusts a TCP/IP priority based on serial payload priority. Accordingly, the router may thus communicate data over the serial-over-TCP/IP session based on the mappings and priority.
摘要翻译：在一个实施例中，路由器使用原始TCP封装在终端单元之间建立串行TCP / IP（传输控制协议/因特网协议）通信会话。对于会话，路由器将串行字符映射到TCP带外（OOB）通信字段，将串行流控制信号映射到TCP / IP接收器窗口广告，并根据串行有效载荷优先级动态调整TCP / IP优先级。因此，路由器因此可以基于映射和优先级通过TCP / IP串行会话传送数据。

摘要： An intelligent network interface card (INIC) or communication processing device (CPD) works with a host computer for data communication. The device provides a fast-path that avoids protocol processing for most messages, greatly accelerating data transfer and offloading time-intensive processing tasks from the host CPU. The host retains a fallback processing capability for messages that do not fit fast-path criteria, with the device providing assistance such as validation even for slow-path messages, and messages being selected for either fast-path or slow-path processing. A context for a connection is defined that allows the device to move data, free of headers, directly to or from a destination or source in the host. The context can be passed back to the host for message processing by the host. The device contains specialized hardware circuits that are much faster at their specific tasks than a general purpose CPU. A preferred embodiment includes a trio of pipelined processors devoted to transmit, receive and utility processing, providing full duplex communication for four Fast Ethernet nodes.

摘要： Some embodiments provide a director agent, a server agent, and a specialized hand-off protocol for improving scalability and resource usage within a server farm. A first network connection is established between a client and the director agent in order to receive a content request from the client from which to select a server from a set of servers that is responsible for hosting the requested content. A second network connection is established between the server agent that is associated with the selected server and a protocol stack of the selected server. The first network connection is handed-off to the server agent using the specialized hand-off protocol. The server agent performs network connection state parameter transformations between the two connections to create a network connection through which content can be passed from the selected server to the client without passing through the director.

摘要： A Transmission Control Protocol (TCP) receiver receives a SYN segment from a TCP initiator that initiates a TCP handshake between the TCP initiator and a TCP server. A first value is extracted from a predefined portion of the SYN segment. A second value is computed using an authentication algorithm that includes at least using a cryptographic hash function that takes as input at least the source IP address of the encapsulating IP packet of the SYN segment and a shared secret between the TCP initiator and the TCP receiver. If the computed second value matches the extracted first value, then the TCP handshake is allowed to continue. If the computed second value does not match the extracted first value, then the TCP handshake is not allowed to continue.
