摘要： A switch element and a method for routing packets in an IB Multi Level switch and network is provided. The method includes determining if alternate routing is enabled for a packet; determining an alternate route address for the packet, if alternate routing is enabled; and routing the packet using the alternate route address, if the alternate route address is valid. The switch element includes a routing table in a port that determines a base route address; and if alternate routing is enabled for a packet, the port determines an alternate route address for a packet; and routes the packet using the alternate route address.

摘要： A cache memory contains a number of RAMs. The RAMs are addressed by independent hashing functions, so as to access a set of locations, one in each RAM. If the required data item is resident in the addressed set, it is accessed. Otherwise, the least-recently used location in the set is selected for overwriting with data from main memory. The contents of the RAM location that is about to be overwritten are saved, and then used to access the memory again in order to address a further set of locations. If any of this further set of locations is less recently used than the saved contents, the saved contents are loaded back into that location.
摘要翻译：高速缓冲存储器包含多个RAM。这些RAM通过独立的散列函数来寻址，以便访问一组位置，每个RAM中有一个。如果所需的数据项目驻留在寻址集中，则会被访问。否则，选择集合中最近最少使用的位置以用来从主存储器的数据进行覆盖。将要保存要重写的RAM位置的内容，然后再次访问存储器，以便寻址另一组位置。如果这些进一步的位置中的任何一个位置比保存的内容不到最近使用，则将保存的内容加载回该位置。

摘要： A method for balancing load on a network by selecting a path based on a load balancing algorithm and assigning one of several pairs of endpoint addresses for a flow based on the path selected. One pair of endpoint addresses corresponds to a first path and another pair of endpoint addresses corresponds to a second path. If the first path is selected, the first pair of endpoint addresses is assigned to the flow. If the second path is selected, the second pair of endpoint addresses is assigned to the flow. In one embodiment, based on the assigned pair of endpoint address, the flow is switched to an endpoint by the selected path.

摘要： Method and system for processing packets received from a network is provided. The system includes an adapter having a processing module that separates a header of a network packet from data, forwards the header to a host system and stores data associated with the network packet in a memory device of the network adapter. The host system processes the header and determines a destination for the network packet data. The method includes determining header boundary in a network packet, wherein an adapter coupled to a host system determines the header boundary; ending header information to the host system; and storing data associated with the network packet in a memory device of the adapter.
