摘要： Discovery of intermediate network devices is performed using a technique that piggybacks upon the existing standard TCP (Transport Control Protocol) “SACK” (Selective Acknowledgment) option in a SYN/ACK packet so that discovery information may be shared between pair-wise-deployed peer intermediate devices when a TCP/IP connection (Transport Control Protocol/Internet Protocol) is first established between network endpoints using a conventional three-way handshake. Use of the SACK option is combined with another technique which comprises modifying the original 16-bit value of the TCP receive window size to a special arbitrary value to mark a SYN packet as being generated by a first peer device. The marked SYN when received by the second peer device triggers that device's discovery information to be piggybacked in the SACK option of the SYN/ACK packet. The first device then piggybacks its discovery information in the SACK option of the ACK packet which completes the three-way handshake.

摘要： Creating different congestion control modules (CCMs) that can be plugged into a network communications stack (e.g., a TCP/IP stack). Software abstractions defining transport control events, congestion control algorithms and other information may be exposed by an application programming interface, e.g., of an operating system, and these abstractions may be used to define a CCM. The network communications stack may be configured to select one of multiple available CCMs to control congestion for a given connection. This selection may be based on any of a variety of factors including, but not limited to: network environment; connection path characteristics; connection link characteristics; a value of a socket parameter of an application; other factors; and any suitable combination of the foregoing. Thus, CCMs may be selected and implemented on a per-connection basis.

摘要： A network interface that provides improved processing of received packets in a networked computer by classifying packets as they are received. Further, both the characteristics used by the network interface to classify packets and the processing performed on those packets once classified may be programmed. The network interface contains multiple receive queues and one type of processing that may be performed is assigning packets to queues based on classification. A network stack within an operating system of the networked computer can route packets classified by the network interface to application level destinations with reduced processing. Additionally, the priority with which packets of certain classifications are processed may be used to allocate processing power to certain types of packets. As a specific example, a computer subjected to a particular type of denial of service attack sometimes called a “SYN attack” may lower the priority of processing SYN packets to reduce the effect of such an attack.

摘要： Techniques are provided for adjusting to changes to the latency for a connection between two nodes on a network. In accordance with some embodiments, when a transmitting node encounters a retransmission timeout for a packet sent to a receiving node, the latency for the connection is newly measured and used to calculate a new retransmission timeout period for subsequent transmissions by the transmitting node. In some embodiments, the latency is not newly measured if the transmitting node receives a selective acknowledgement from the receiving node, since a selective acknowledgement may indicate that congestion on the network is only temporary.

摘要： Efficiently polling a DMA module to determine if the DMA copying of a packet payload to an application buffer is complete. For communication packets received from a network, a processing module may be configured to poll the DMA module at times when it is likely that the DMA copying of packet payloads is complete. Packets may be received and processed in batches. The polling of the DMA module for a packet belonging to a first batch may be deferred until the processing of a next batch. An exception may occur if a predefined amount of time elapses following the completion of the processing of the first batch before the next batch is received. In response to the predefined amount of time elapsing before the receipt of the next batch, the DMA module may be polled, i.e., prior to the next batch being processed.
摘要翻译：有效地轮询DMA模块，以确定分组有效载荷到应用程序缓冲区的DMA复制是否完整。对于从网络接收的通信分组，处理模块可以被配置为在可能的情况下对分组有效载荷的DMA复制完成的轮询DMA模块。数据包可能会被批量接收和处理。属于第一批的数据包的DMA模块轮询可能会延迟到下一个批处理。如果在接收到下一个批次之前完成第一批处理完成后经过预定义的时间量，则可能会发生异常。响应于在接收下一个批次之前经过的预定义的时间量，可以轮询DMA模块，即在下一个批处理之前。

摘要： Methods and apparatus are provided for controlling live migration of a virtual machine from a first host to a second host in a data center. A virtual machine manager may distribute to at least one host in a virtual network an updated mapping policy that maps a customer address of the virtual machine to a provider address of the migrated virtual machine. The updated mapping policy enables hosts in the virtual network to communicate with the migrated virtual machine. The updated mapping policy can be a shadow policy. The shadow policy is transmitted to hosts in the virtual network by the virtual machine manager before live migration of the virtual machine completes and is maintained by recipient hosts in an inactive state until triggered. The virtual machine manager notifies hosts in the virtual network to activate the shadow policy when live migration completes.

摘要： Aspects of the subject matter described herein relate to selecting a source interface with which to establish a connection. In aspects, a profile for each network location a host has seen is maintained in a data store. The profile includes information about the network interfaces available to a source host at the network location. This information indicates, among other things, the reliability of each interface of the source host. Based on the profile, an interface is selected with which to establish a connection. If the interface is unsuccessful in establishing the connection, the interface is de-prioritized and another interface may be selected.
