摘要： One or more modules include a first portion that teams together multiple physical network interface ports of a computing system to appear as a single virtual network interface port to a switch to which the physical ports are linked. A second portion determines a receive port upon which a packet of a TCP session was received. A third portion assigns a transmit port to be the receive port, wherein the transmit port is used by the computing system to transmit packets of the TCP session. The third portion assigns the transmit port prior to a TCP offload engine (TOE) being enabled to offload from the system CPU processing of packets of the TCP session transceived on the assigned transmit/receive port. If a subsequent packet for the TCP session is received on a different second port, the transmit port is reassigned to be the second port.

摘要： Monitoring in switch networks is disclosed. Ports in a switch may include monitoring circuitry and a monitoring tap which allows traffic data to be diverted for monitoring prior to any significant transformation of the traffic by the regular port logic. Furthermore, the monitoring circuitry can receive signaling and convert it for subsequent analysis by a protocol analyzer. The ports and paths in the switch network can be configured to create monitor paths to enable diverted traffic data to be passed through the network to locations where a protocol analyzer can be easily attached. With wide bandwidth ports, there is no disruption to the system. Because only a copy of the data is routed to the analyzer, there is no change to the original signal path and latency is identical with or without the analyzer.
摘要翻译：披露了交换机网络中的监控。交换机中的端口可以包括监控电路和监控分接头，其允许在通过常规端口逻辑的业务的任何重大变换之前转发流量数据以进行监控。此外，监控电路可以接收信令并将其转换成协议分析器进行后续分析。交换机网络中的端口和路径可以配置为创建监视路径，以使转移的业务数据能够通过网络传递到协议分析器可以轻松连接的位置。对于宽带宽端口，系统不会中断。因为只有数据的副本才能路由到分析仪，所以原始信号路径没有改变，延迟与分析仪是否相同。

摘要： An Ethernet node includes a receiver and transmitter for coupling to an Ethernet link for transceiving Ethernet frames with a remote Ethernet node at a remote end of the Ethernet link. The Ethernet node sends to the remote Ethernet node credit information that enables the remote Ethernet node to know an amount of Ethernet frames the remote Ethernet node is allowed to send to the Ethernet node. The credit information may be specified on a VLAN priority basis and may be included in a header piggy-backed on a host Ethernet frame or may be included in an explicit frame. The credit information may incrementally replenish credits or may specify an absolute credit amount and may be sent in response to processing frames, detection of a frame error, receipt of a request from the remote node or other events.

摘要： Methods and systems are provided for verifying use of encryption keys. A request for verification information may be sent by a network element (e.g., server), with the request comprising combination of one or more identifiers, the combination associated with a particular I/O operation. The request may be sent to another element, which may be a centralized encryption management element (e.g., management server). In response to the request, key use verification information generated for the particular I/O operation may be received, and may be used thereafter in validating a corresponding encryption key, which may be used during data encryption or decryption, based on the received key use verification information and locally generated verification information associated with the particular I/O operation. The one or more identifiers include at least one of a target identifier, a LUN identifier, and a LBA range identifier.

摘要： A method for offloading Fiber Channel transmit data in an I/O operation. The transmit data includes Fiber Channel sequences, each Fiber Channel sequence includes multiple frames. The method includes generating a single transmit sequence request descriptor for transmitting all of the plurality of frames; creating an Ethernet header, a FCoE encapsulation header, and a Fiber Channel header for each frame in response to information in the transmit sequence request descriptor; creating start of frame and end of frame delimiters; inserting data into each frame; computing Fiber Channel CRC and Ethernet FCS for each frame; and transmitting the plurality of frames over a network. In each of the plurality of frames, the Ethernet header precedes the FCoE encapsulation header, which precedes the Fiber Channel header, which precedes the data. The data is followed by the Fiber Channel CRC, which is followed by the Ethernet FCS.

摘要： Methods and systems are provided for managing power consumption in network devices. In a network device that may comprise a plurality of ports, each of which being identified by a unique identifier and being adapted to handle separate network traffic, it may be determined whether a first port of the network device may need to be reactivated, where the first port may have been previously shut down by directing of traffic corresponding to the first port, through a virtual port generated on a second port. When the first port is to be reactivated, the virtual port may be turned off, and the first port may then be reactivated. Traffic being routed through the virtual port may be routed before shutting it down; and the paused traffic to and from the network device may be resumed through the first port after it is reactivated.

摘要： Disclosed herein is an improved method of using sockets in connection with TCP over certain local networks, such as the enhanced Ethernet. In particular, an accelerated socket protocol is provided to enhance data communications between different host computer systems connected to an enhanced Ethernet network. Under the accelerated socket protocol, a host computer, while sending a number of data packets, is able to indicate a particular data packet is a last ready data packet out of all packets ready to be sent by setting a PUSH bit in that particular data packet, which triggers an automatic acknowledgement message that confirms receipt of data from the receiver. In addition, while receiving data packets, the host computer can advertise an effective window that corresponds to the actually available receiving space in the host computer.
