摘要： A system and method for scalable status change detection in a network of nodes includes embedding node coordinate positions into a virtual map environment. A cluster of nodes are represented with a representative node to form a hierarchy of nodes and clusters where changes in a status of the representative node imply a status change in the nodes of the cluster. By selectively monitoring the representative nodes for the changes in status, the representative nodes create a capability for scalable monitoring of the network.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, an improved mechanism for handling receipt of data packets in a system utilizing an offload network adapter. The offload network adapter may include logic that permits the offload network adapter to delay notification of data reception to the host system in different ways. The advantage of delaying the notice of data packet reception to the host system is the potential for aggregation of several data packets, which can arrive immediately after the first one, for example, in a single notification. Given a stream with continuous data packet arrival, a value may be set, either statically or dynamically, for notification delay and this value may be configurable for the host system per communication socket.

摘要： A mechanism for bottleneck avoidance is provided in an intelligent adapter. The mechanism allows the adapter to be used such that host/adapter system throughput is optimized. The bottleneck avoidance mechanism of the present invention determines when the adapter becomes a bottleneck. If certain conditions exist, then new connections are refused so that the adapter can process packets for existing connections. If certain other conditions exist, the adapter may migrate workload to the host processor for processing. These conditions may be determined by comparing memory usage or central processing unit usage to predetermined thresholds. Alternatively, the conditions may be determined by comparing adapter response time to host response time.

摘要： A method of generating an annotated network topology of a network is described. The method includes determining available bandwidth “B” of a network on a network path connecting a pair of endpoints by performing Transfer Control Protocol (TCP) flows between the pair of endpoints, the network having a plurality of network paths, identifying a bottleneck link in the network path, and annotating all edges in a network path, wherein available bandwidth annotation of links inside the network is determined using end-to-end network measurements. A system for generating the annotated network topology of a network is also described.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter is provided. The connection establishment mechanism provides the ability to offload connection establishment and maintenance of connection state information to the offload network adapter. As a result of this offloading of connection establishment and state information maintenance, the number of communications needed between the host system and the offload network adapter may be reduced. In addition, offloading of these functions to the offload network adapter permits bulk notification of established connections and state information to the host system rather than piecemeal notifications as is present in known computing systems.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided. The memory management mechanism permits both buffered sending and receiving of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism permits grouping of DMA buffers that can be shared among specified connections based on any number of attributes. The memory management mechanism further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system in bulk, and expedited transfer of data to the host system.
