    摘要： An impingement cooling sleeve includes a sleeve body having an inner surface to face a transition duct and an outer surface facing opposite the inner surface. At least one cooling hole is formed within the sleeve body and is used to direct cooling air toward the transition duct. At least one conduit member is attached to the sleeve body and is associated with the at least one cooling hole. The conduit member has a first opening to define an air inlet and a second opening to define an air outlet. In one example, the first opening is spaced apart from the outer surface of the sleeve body by a distance. In one example, the first opening comprises an annular end face surface that defines a plane that is obliquely orientated relative to the outer surface of the sleeve body.

    摘要： TCP/IP traffic passing over a TCP connection is initially load balanced by a TCP offload network interface device (NID) in fast-path between multiple ports of an aggregation team. A failure then occurs on one of the ports. Processing of the TCP connection then switches to slow-path. The function of the failed port is then assumed by another functioning port of the team such that fast-path processing of the TCP connection by the TCP offload NID automatically resumes. The two ports of the TCP offload NID (the failed port and the port that assumes its functionality) use different MAC addresses. Fast-path load balancing and fail-over are therefore possible without the use of a Fast-Etherchannel switch that would have required the two ports to use the same MAC address.
