摘要： A method in a network element includes processing input packets using a set of two or more functions that are defined over parameters of the input packets. Each function in the set produces respective interim actions applied to the input packets and the entire set produces respective end-to-end actions applied to the input packets. An end-to-end mapping, which maps the parameters of at least some of the input packets directly to the corresponding end-to-end actions, is cached in the network element. The end-to-end mapping is queried with the parameters of a new input packet. Upon finding the parameters of the new input packet in the end-to-end mapping, an end-to-end action mapped to the found parameters is applied to the new input packet, without processing the new input packet using the set of functions.

摘要： A method for communication, in a network element that includes multiple ports, includes buffering data packets entering the network element via the ports in input buffers that are respectively associated with the ports. Storage of the data packets is shared among the input buffers by evaluating a condition related to the ports, and, when the condition is met, moving at least one data packet from a first input buffer of a first port to a second input buffer of a second port, different from the first port. Respective output ports, via which the buffered data packets are to exit the network element, are selected from among the ports. The buffered data packets are forwarded to the selected output ports.

摘要： Systems and methods for input/output command management. In embodiments of the invention an input/output command fully executes after a lock has been obtained for the command on all storage segments relating to the command, in a predetermined order. Some embodiments of the invention allow overlapping access to storage and/or to individual storage segments by a plurality of input/output commands. In some embodiments of the invention, prioritization of commands is facilitated through the usage of a sharing policy and/or wakeup policy.

摘要： A network interface adapter includes an outgoing packet generator, adapted to generate an outgoing request packet for delivery to a remote responder responsive to a request submitted by a host processor and a network output port, coupled to transmit the outgoing request packet over a network to the remote responder. A network input port receives an incoming response packet from the remote responder, in response to the outgoing request packet sent thereto, as well as an incoming request packet sent by a remote requester. An incoming packet processor receives and processes both the incoming response packet and the incoming request packet, and causes the outgoing packet generator, responsive to the incoming request packet, to generate, in addition to the outgoing request packet, an outgoing response packet for transmission to the remote requester.

摘要： There is provided according to an example of the claimed subject matter, a system and a method for managing access to a shared storage entity. According to an example of the claimed subject matter, a system for managing access to a shared storage entity can include two or more initiator entities, two or more local sequencing agents and an arbitration module. Each of the two or more local sequencing agents can be associated with a respective one of two or more initiator entities which generate I/O requests for accessing the shared storage entity. Each local sequencing agent can be adapted to locally sequence its respective initiator entity's I/O requests. The arbitration module can be adapted to manage an access cycle to the shared storage entity by allocating to each one of the plurality of initiator entities a monolithic/continuous chunk of the access cycle to implement its own I/O access sequence, wherein chunk allocation is determined according to subframe allocation criteria related to the functional characteristics of each of the initiator entities.
