    Abstract: A system and method can implement highly available Internet Protocol (IP) based communication across multiple independent communication paths. The system can have different IP addresses associated with different interfaces and communication paths and can implement communication fail-over as part of the communication layers above the IP layer, e.g. at the application level. The system can provide a balance between an average fail-over time and implementation complexity, and can achieve simplicity and robustness while providing high communication performance.

    Abstract: Systems and methods for multicast send duplication instead of replication in a high performance computing environment. A method can provide a plurality of switches, a plurality of hosts, the plurality of hosts being interconnected via the plurality of switches, wherein a host of the plurality of hosts comprises a multicast sender node, the sender node comprising a system image generation module and a current message sequence module. The method can organize the plurality of switches into two rails, the two or more rails providing redundant connectivity between the plurality of hosts. The method can send two or more duplicate multicast packets on different rails. Upon a receiving node receiving at least two versions of the same multicast packet, only one will be delivered to the communication stack/clients above the layer that handles the encapsulation header.

    Abstract: A system and method can ensure Internet Protocol (IP) address and node name consistency when performing remote transactions via multiple un-related IP addresses for the same remote peer. The system can ensure that all cooperating peer nodes are in full agreement of the names and IP addresses at any point in time. In particular, when network configurations can be updated dynamically, the system can ensure that such updates do not lead to inconsistent or failed transactions because a peer node has a stale view of what addresses to use. Furthermore, the peer node that initiates the transaction can verify that all the other peer nodes have exactly the same view of the overall system configuration, in order to ensure that each distributed transaction is carried out using consistent address information.

    Abstract translation: 当通过同一个远程对等体的多个不相关IP地址执行远程事务时，系统和方法可以确保Internet协议（IP）地址和节点名称的一致性。 系统可以确保所有合作对等节点在任何时间点完全符合名称和IP地址。 特别地，当网络配置可以动态更新时，系统可以确保这样的更新不会导致不一致或失败的事务，因为对等节点具有要使用的地址的陈旧视图。 此外，启动事务的对等节点可以验证所有其他对等节点具有与整个系统配置完全相同的视图，以便确保使用一致的地址信息来执行每个分布式事务。

    Abstract: A system and method can support network management in a network environment. The network environment can include a plurality of configuration daemons (CDs), wherein each CD resides on a switch in the network environment. The CD operates to receive a configuration file that includes a list of known management key (M_Key) values. Furthermore, the CD operates to store the configuration file, and make the configuration file available to a local subnet manager(SM) on the switch, wherein the local SM is associated with a currently used M_Key value. Then, the CD operates to update the local SM with a new M_Key, after receiving an instruction from a master CD that is associated with a master SM in the network environment.
