    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: 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: A method for improving the efficiency of Internet Protocol Control Block (INPCB) lookup operations at a TCP receiver and TCP sender. The TCP/IP stack is modified such that every data packet generated includes both data and INPCB address information. Specifically, the TCP/IP stacks of a sending device and a receiving device are modified to provide a contemporaneous transmission of INPCB addresses along with each data packet. The TCP/IP stack of the receiver is also modified such that the receiver echoes this INPCB address along with each TCP packet sent back to the sender to eliminate the necessity of an INPCB address lookup operation at the sending device. Contemporaneous transmission of data and INPCB addresses facilitates direct delivery of data packets to the corresponding sockets.

    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.

    摘要: A method, system and apparatus for maintaining a two-byte identification field of IP headers when a Gigabit Ethernet is in use are provided. Since the IP identification field is of two bytes, there is a limited number of identification numbers that may be used. Due to the high data transfer rate of the Gigabit Ethernet, this number may be reached within one second. Hence, there may be a possibility that two or more packets may have the same identification number while in transit. In a representative embodiment, one identification number is used for packets that may not be fragmented; thus, freeing the rest of the numbers for packets that may be fragmented.
