摘要： A method, apparatus, and computer instructions for processing packets in a network layer. A packet is received for transmission in which the packet includes a destination address. A routing entry for the destination address is identified. A determination is made as to whether a flag indicating the packet is to be broadcast has been set in the routing entry. Header information is placed in the packet in which the header information indicates that the packet is a broadcast packet in response to the flag being set.

摘要： A method, system, and computer program product in a computer-readable medium for delivering data, received from a network, to a storage buffer assigned to an application is proposed. An application designates a communication buffer within a local data processing system for buffering data communicated with an application. The local data processing system reports to a network interface of the local data processing system a memory address of the designated communication buffer, and the data processing system creates a cookie containing the memory address. The data processing system then sends the cookie form the local data processing system to a remote data processing system, such that the remote data processing system may address data directly to the designated communication buffer.

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.

摘要： A method, system and apparatus for reducing dataflow disruption when increases in path maximum transmission unit (PMTU) are being detected are provided. Conventionally, when increases in PMTU are being detected, an increased-in-size data packet is sent by a transmitting host. If an intermediate link is unable to process the data packet through, it drops the data packet and sends an error message to the transmitting host. The transmitting host has to reduce the size of the data packet and resend it. The procedure outlines in this disclosure obviates the need to resend the data packet. It does so by transmitting an old data packet that has been increased in size. Hence, there is no need to resend the data packet if it is dropped.

摘要： A method, system and apparatus for multicasting or broadcasting a piece of data from one partition of a partitioned computer system to a plurality of partitions of the system are provided. When a partition needs to transfer data to more than one partition of the system, the partition first stores the data into a global memory accessible by all partitions of the system. The memory is then marked “read-only” to ensure that the data is not over-written and the Ids (identifications) of the recipient partitions are passed to a piece of firmware or hardware of the computer system. This firmware or hardware then alerts the recipient partitions that there is a piece of data ready to be read in the memory. Once all the recipient partitions have read the data, the global memory is reverted to a “read” and “write” memory.

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.

摘要： Responsive to detecting a need for a mobile device to transfer out of a first network, requests are sent from the mobile device to a communication endpoint in mSCTP. The first request is to stop transmissions to a first address of said mobile device. The second request is to add an intermediary address of a mobility support service designated for receiving any communications already in transmission when the first request is sent. The communication link for the mobile device is then transitioned from the current address at the first network to a second address at a second network. The first network and the second network are non-intersecting networks. The mobile device then indicates to the mobility support service that the handover from the first network to the second network is complete. The mobility support service responds to the completion by sending a third request in mSCTP to the communication endpoint to continue communication with the mobile client at the second address.
