摘要： Coupling circuitry (such as an intelligent network adaptor) couples a network to a host. The host is executing an operating system and is configured for transfer of data between the host and at least one peer via the network using at least one stateful connection to a peer according to a connection-oriented protocol. Indications of attempts to establish stateful connections with a host are received. The coupling circuitry processes each of the received indications by attempting to establish a stateful connection to a peer indicated by that connection establishment attempt indication such that, for a genuine attempt by a peer to establish a stateful connection with the host, the coupling circuitry interoperates with the peer to perform establishment-phase protocol processing of the attempted stateful connection. For each of the established stateful connections, the coupling circuitry operates to cause a state of that established stateful connection to be provided from the coupling circuitry to the host, wherein the operating system of the host handles data transfer phase protocol processing of that established stateful connection.

摘要： Packet switching is facilitated between a source and a destination through a network interface card. In accordance with an aspect, a NIC is configured to switch ingress packets—coming from the network—selectively to one or multiple destinations (in a NIC which is capable of replicating packets) on the host computer, and alternatively or additionally (in a NIC which is capable of replicating packets) back to one or multiple destinations on the network. In multi-port NICs, this capability effectively allows a NIC to perform the basic functions of a standalone network switch as well as additional useful functions.

摘要： Efficient congestion control in a packet switched network is facilitated between at least one source and at least one destination. The source organizes known destinations, at above the link layer, into groups, each group containing one or more destinations. The group for each source packet may be identifiable by data natively present in the packet header. In some example, the source assigns an arbitrary identification to each group, and the source labels packets destined to a group with the identification for that group. A network node sends “PAUSE” packets containing at least one pause information indication back to a traffic source. The pause indication is associated with at least one group identification used by the source. The source reacts to the pause request by stopping or resuming packet transmission to the at least one group identification. Transmission to other destination groups is not affected.

摘要： The present invention is in the field of virtualization of Network Interface Cards and Controllers (NIC) that connect to for example a host computer that can have multiple functions and OS's (referred to as guest functions and guest-OS's) running on it simultaneously and, in particular, relates to the virtualization of the operation of a single NIC such that it can be used simultaneously by multiple guests in such a manner that memory references due to the network traffic originating from and destined to a particular guest is kept separate from other network traffic, and that allows the Media Access Controller (MAC) within the NIC to operate such that it only accepts network packets that are destined to one of the guest-functions or guest-OS's, and the MAC is not required to operate in promiscuous mode where it accept all incoming packets in order to implement the virtualization features.

摘要： A method of operating intelligent network interface circuitry facilitates the tunneling of packets between at least one process, executing on a host computer, and a peer via a network, via the network interface circuitry. Packets are received from the process executing on the host computer. Modulation event tokens are managed, including receiving and providing modulation event tokens. Modulation events are processed. It is decided whether to transmit the received packets out to the network in association with modulation event processing, and the received packets are transmitted out to the network based on the deciding step. Based on a result of the modulation events processing step, modulation event tokens are caused to be fed back for receipt by the modulation event tokens managing step. As a result, the packets are tunneled through the network interface circuitry and the transmission of the packets is modulated out to the network.

摘要： A host is coupled to a network via an intelligent network adaptor. The host is executing an application configured to receive application data from a peer via the network and the intelligent network adaptor using a stateful connection according to a connection-oriented protocol. The intelligent network adaptor performs protocol processing of the connection. Application data is copied from host memory not configured for access by the application (possibly OS-associated host memory) to host memory associated with the application (application-associated host memory). The application data is received from the peer by the intelligent network adaptor and copied to host memory not configured for access by the application. The operating system selectively provides, to the intelligent network adaptor, information of the memory associated with the application. At least one portion of the application data for the connection is provided directly from the intelligent network adaptor to the memory associated with the application.

摘要： Transfer of data is facilitated between at least one application and a peer via a network. Data destined for the peer is provided from the at least one application for transmission to the peer via the network. Modulation event tokens are managed, and protocol processing of the data with the peer is based in part on a result of the modulation event tokens managing such that protocol processed data is caused to be transmitted to the peer via the network nominally with desired data transmission rate characteristics. A result of the protocol processing step is fed back to the to the modulation event tokens managing. The desired data transmission rate characteristics may include, for example, shaping and pacing.
