摘要： A mechanism is provided for identifying a snooping device in a network environment. A snoop echo response extractor generates an echo request packet with a bogus MAC address that will only be received by a snooping device. The snoop echo response extractor also uses an IP address that will cause the snooping device to respond to the echo request. Non-snooping devices discard the echo request packet. Upon receiving the response packet, the snooping device is identified.

摘要： A host enables any adapter of multiple adapters of the host to concurrently support any VIPA of the multiple VIPAs assigned to the host. Responsive to a failure of at least one particular adapter from among the multiple adapters, the host triggers the remaining, functioning adapters to broadcast a separate hardware address update for each VIPA over the network, such that for a failover in the host supporting the multiple VIPAs the host directs at least one other host accessible via the network to address any new packets for the multiple VIPAs to one of the separate hardware addresses of one of the remaining adapters.

摘要： The reassembly timer in a TCP/IP receiver is dynamically set to avoid data corruption on fast networks caused by IP identification wrap-around. A receiver independently sets the reassembly timer to a first reassembly time set by the user for fast networks or to a second reassembly timer set by the user for slow networks based on whether the receiver and sender are on the same subnet.

摘要： A computer implemented method and data processing system for the detection and recovery of a network interface card TCP acceleration offload failure. Responsive to a failure to receive an acknowledgement of a transmission control protocol segment containing a request for a transmission control protocol offload function in a network interface card, the transmission control protocol segment is retransmitted without the request for a transmission control protocol offload function. When an acknowledgement of the retransmitted transmission control protocol segment without the request for a transmission control protocol offload function is received, a counter is incremented which indicates a failure of the transmission control protocol offload function. Responsive to the counter exceeding a predefined number of allowed failures, all requests to the transmission control protocol offload function for the network interface card are stopped.

摘要： An embodiment allows an application to use a unique feature of an operating system residing on a LPAR different than its own. If the application makes a request for a feature not available in the operating system that it runs on, a transporter module can check its records to verify if such a feature exists on another operating system in a different LPAR. If it does exist, the transporter communicates to a facilitator of the operating system on the different LPAR though a hypervisor. The facilitator provides the unique feature to the transporter, who then forwards it to the application in need.
摘要翻译：实施例允许应用使用驻留在不同于其自身的LPAR上的操作系统的独特特征。如果应用程序要求其运行的操作系统中不可用的功能，则传输器模块可以检查其记录以验证是否在不同LPAR中的其他操作系统上存在此类功能。如果确实存在，运输商通过管理程序与不同LPAR上的操作系统的协调人进行通信。协调人为运输商提供了独特的功能，然后将其转发到需要的应用程序。

摘要： A graphic user interface of a network client (106) includes a stock ticker from a stock server (110) and a news sidebar from a news server (112) over the IP addresses advertised to the client (106) in its list of multi-homed addresses from the video server (104) specified under Stream Control Transmission Protocol (SCTP). The client accepts real-time data from the stock exchange server and the news agency server on the multi-homed IP addresses designated in the association with the video server (104) without knowing that the data is coming from a different source than the video server (104). The real-time data feeds from the video, stock and news servers are aggregated on the client (106) with enhanced speed because the feeds come directly to the client and not via the video server. The operating systems of the home server and remote servers utilize SCTP and specialized commands to implement the enhanced speed of real-time data aggregation being streamed to network clients without requiring modifications to existing client systems.

摘要： The server side Transfer Control Protocol is modified so that the server returns a SYNACK message with the window size equal to zero if the server is busy. When a client sends a TCP connection request and receives a synchronization acknowledgement message with the window size equal to zero, the client knows that the server received the connection request and that the server is busy. The client may then send an acknowledgement message to complete the three-way synchronization handshake, thus successfully completing the connection. Thereafter, the client side TCP may probe the server side TCP until a window update message is received from the server. When the server sends a window update message to set the window size to a non-zero size, the client knows that the server is no longer busy and the client application may then use the TCP connection.
摘要翻译：修改服务器端传输控制协议，以便服务器返回SYNACK消息，如果服务器正忙，则窗口大小等于零。当客户端发送TCP连接请求并接收到窗口大小等于零的同步确认消息时，客户端知道服务器接收到连接请求，并且服务器正忙。然后，客户端可以发送确认消息以完成三次同步握手，从而成功地完成连接。此后，客户端TCP可以探测服务器端TCP，直到从服务器接收到窗口更新消息。当服务器发送窗口更新消息以将窗口大小设置为非零大小时，客户端知道服务器不再忙，客户端应用程序可能会使用TCP连接。

摘要： TCP congestion avoidance is implemented upon retransmission of a packet and is reverted back to the original congestion state upon receipt of an early acknowledgement (ACK), indicating reordering of packets, thereby eliminating a needless restriction on TCP bandwidth. Upon receiving an ACK to a retransmitted packet, it is determined if the ACK resulted from receipt of the original reordered packet or the retransmitted packet, based on the arrival time of the ACK at the sender. If the round-trip-time (RTT) for the retransmitted packet is much lower than the average or current calculated RTT for the network link between sender and receiver, then the retransmission occurred as a result of a reordering event, and the congestion window is restored back to its value prior to the retransmission, thereby permitting the network link to continue operating at its original increased throughput.
摘要翻译： TCP拥塞避免在分组重传时实现，并且在接收到指示重新排序分组的早期确认（ACK）时被恢复到原始拥塞状态，从而消除对TCP带宽的不必要的限制。在向重传的分组接收到ACK时，基于ACK在发送方的到达时间确定ACK是否从接收到原始重新排序的分组或重传分组而产生。如果重发分组的往返时间（RTT）远低于发送方和接收方之间的网络链路的平均或当前计算的RTT，则重新发送作为重排序事件的结果，拥塞窗口为在重传之前恢复其值，从而允许网络链路以其原始增加的吞吐量继续运行。

摘要： Methods, systems, and media are disclosed for improved granularity of a response-request communication on a networked computer system. One example embodiment includes receiving the request-response communication by the networked computer system, and associating the request-response communication with a port, having a nodelay setting, from a set of ports on the networked computer system. Further, the example embodiment includes enabling, based upon the associating, the nodelay setting upon connection of the request-response communication with the port. Further still, the example embodiment includes sending, in accordance with the enabling, the request-response communication to a destination in communication with the networked computer system. In addition, further example embodiments include configuring the ports on the networked computer system with nodelay values indicating whether a particular port is assigned nodelay or no nodelay for a request portion or request portion of a request-response communication connecting to that particular port.
