摘要： A method and management port for an indirect loop protocol associated with an interconnect device. In one embodiment, a method to handle a request sent to an interconnect device includes receiving the request at a destination switch from a host network adapter; generating a response to the request in the destination switch; and returning the response to the host network adapter, wherein the destination switch includes a management port for addressing the interconnect device that implements an indirect loop protocol.

摘要： In one embodiment a method for processing an incoming packet in a port of an interconnect device includes speculatively forwarding the incoming packet to multiple buffers within the port prior to determining which of the multiple buffers is a target buffer for the packet, decoding the packet, and determining which of the multiple buffers is the target buffer for the packet using the decoded packet. The method further includes notifying an agent associated with the target buffer that the target buffer is an intended owner of the data packet. In one embodiment, agents associated with the multiple buffers are designated to process packets that are not subject to a credit-based flow control method.
摘要翻译：在一个实施例中，用于在互连设备的端口中处理输入分组的方法包括在确定多个缓冲器中的哪一个是分组的目标缓冲器，对分组进行解码之后，将输入分组推测地转发到端口内的多个缓冲器，以及使用解码的分组来确定多个缓冲器中的哪个是分组的目标缓冲器。所述方法还包括通知与所述目标缓冲器相关联的代理，所述目标缓冲器是所述数据分组的预期所有者。在一个实施例中，与多个缓冲器相关联的代理被指定为处理不受基于信用的流量控制方法的分组。
