摘要： A method, system and apparatus for negotiating parameters for an IPSec connection between a requesting client and an iSCSI system using a computer system other than an iSCSI system are provided. By design, the iSCSI system monitors TCP (Transmission Control protocol) port 500 for secure requests. When a request enters port 500, the iSCSI system transmits all information received on port 500 to a computer system better suited to handle IPSec parameter negotiations. After the computer system has negotiated the parameters, the parameters are passed to the iSCSI system for a secure data transaction to ensue.

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： Network input processing is distributed to multiple CPUs on multiprocessor systems to improve network throughput and take advantage of MP scalability. Packets are received by the network adapter and are distributed to N receive buffer pools set up by the device driver, based on N CPUs being available for input processing of packets. Each receive buffer pool has an associated CPU. Packets are direct memory accessed to one of the N receive buffer pools by using a hashing function, which is based on the source MAC address, source IP address, or the packet's source and destination TCP port numbers, or all or a combination of the foregoing. The hashing mechanism ensures that the sequence of packets within a given communication session will be preserved. Distribution is effected by the network adapter, which sends an interrupt to the CPU corresponding to the receive buffer pool, subsequent to the packet being DMAed into the buffer pool. This optimizes the efficiency of the MP system by eliminating any reliance on the scheduler and increasing the bandwidth between the device driver and the network adapter, while maintaining proper packet sequences. Parallelism is thereby increased on network I/O processing, eliminating CPU bottleneck for high speed network I/Os and, thus, improving network performance.
摘要翻译：网络输入处理分配到多处理器系统上的多个CPU，以提高网络吞吐量并利用MP可扩展性。数据包由网络适配器接收，并分配给设备驱动程序设置的N个接收缓冲池，基于可用于数据包输入处理的N个CPU。每个接收缓冲池都有一个关联的CPU。数据包是通过使用基于源MAC地址，源IP地址或数据包的源和目标TCP端口号的散列函数或全部或前述的组合来访问N个接收缓冲池中的一个的直接存储器。散列机制确保给定通信会话内的数据包序列将被保留。分配由网络适配器实现，该网络适配器在将数据包DMA到缓冲池之后向与接收缓冲池相对应的CPU发送中断。这通过消除对调度器的任何依赖，并增加设备驱动程序和网络适配器之间的带宽，同时保持适当的数据包序列，从而优化了MP系统的效率。因此，在网络I / O处理上并行性增加，消除了高速网络I / O的CPU瓶颈，从而提高了网络性能。

摘要： A method, computer program product and system for detecting a first-hop dead gateway. In one embodiment, a method comprises the step of sending a TCP packet of data from an application of a sender host to a receiver host through a first gateway, where the first gateway is a first-hop away from the sender host. The method further comprises the step of TCP failing to receive an acknowledgment of received data from the receiver host. The method further comprises the step of deleting an ARP entry associated with the first gateway in the sender host. The method further comprises the step of establishing a new communication using the first gateway by the application or new application of the sender host. The method further comprises the step of sending an ARP request to the first gateway by the sender host. If the sender host receives a response from the first gateway, then the method further comprises the step of sending a TCP or non-TCP packet of data using the first gateway if the new communication was a TCP or non-TCP communication, respectively. If the sender host does not receive a response from the first gateway, then the method further comprises the step of selecting an alternative path through an alternative first-hop gateway in the routing table of the sender host. The application or new application of the sender host then sends the TCP or non-TCP packet of data using the alternative gateway if the new communication was a TCP or non-TCP communication, respectively.

摘要： Network input processing is distributed to multiple CPUs on multiprocessor systems to improve network throughput and take advantage of MP scalability. Packets received on the network are distributed to N high priority threads, wherein N is the number of CPUs on the system. N queues are provided to which the incoming packets are distributed. When one of the queues is started, one of the threads is scheduled to process packets on this queue at any one of the CPUs that is availableat the time. When all of the packets on the queue are processed, the thread becomes dormant. Packets are distributed to one of the N queues by using a hashing function based on the source MAC address, source IP address, or the packet's source and destination TCP port number, or all or a combination of the foregoing. The hashing mechanism ensures that the sequence of packets within a given communication session will be preserved. Distribution is effected by the device drivers of the system. Parallelism is thereby increased on network I/O processing, eliminating CPU bottleneck for high speed network I/Os, thereby improving network performance
