摘要： A generic multi-stage nested hash unit that provides support for generic, multi-stage nested hashes accelerates a wide range of security algorithms and protocols. The supported security algorithms and protocols include SSL v3 MAC, TLS PRF, and SSL v3 Key Material Generation. The hash unit allows the same code to be used to generate the MAC even when the MAC algorithms are different, for example, for SSL and TLS protocols.

摘要： Method and apparatus for performing centralized cyclic redundancy checks (CRC). For one embodiment a current thread of execution compares a connection index with that of a previous thread of execution. If they share the same connection index, a CRC calculation may be performed without providing a CRC residue to a centralized CRC unit since the most recently produced CRC residue by would be associated with a preceding sequential cell of the same packet. For an alternative embodiment a current thread of execution requests a CRC calculation and provides a connection index to the centralized CRC unit, which is used to access a content addressable memory (CAM). A hit in the CAM indicates that the CRC unit may use the CRC residue associated with the connection index in the CAM since it would have resulted from a preceding sequential cell.

摘要： Congestion management techniques for communication networks are described. In an example embodiment, an apparatus may comprise circuitry, a communication component for execution by the circuitry to receive a send request identifying a message to be received from an initiator device via a packet transfer process and transmit an acceptance to grant the send request, and a scheduling component for execution by the circuitry to determine whether to defer the packet transfer process and in response to a determination to defer the packet transfer process, select a value of a delay parameter to be included in the acceptance. Other embodiments are described and claimed.

摘要： A network packet may be forwarded by reading a table containing a plurality of flags to determine which of the plurality of flags is set or cleared and performing an operation on the packet to decapsulate or encapsulate the packet in accordance with values of the flags.
