摘要： Methods, systems, and apparatus provide efficient and flexible networking quality of service as well as transport protocol design. A hybrid transport/network quality of service (HNTQ) scheme improves the performance of TCP over specific links or network paths that are subject to high latency, a high bandwidth-delay product, high packet loss, and/or bit errors. A callback mechanism can be used between a packet scheduler and a transport module to control the transmission rate of packets across one or more connections or links.

摘要： In a network, a query originator injects queries of network devices into the network at a query node using query messages. The network transports the query messages to the network devices, or to network nodes at which queries about the network devices can be answered. Query responses from the network devices or network nodes are directed through the network to a collection node or nodes. As an internal network node receives multiple query responses from network devices, the internal network node might aggregate, as needed, the multiple query responses into an aggregated query response that preferably occupies less bandwidth than the aggregated multiple query responses. Where the result desired at the collection node is a computed function of the multiple query responses, the computed function can be performed at each internal network node on the multiple query responses received at that node, thus distributing the computation needed to form a collected response to the query. Queries might request real-time or non-real-time responses and queries might request one response, periodic responses or one response for each occurrence of an event. The internal network nodes might store lookup tables, or access a centralized lookup table, that specify details of queries, thus obviating the need for each query message to carry all of the necessary details of the query.

摘要： Protocol acceleration is performed between clients and servers over a network wherein transport connections are established between clients/servers and/or their proxies for acceleration of traffic that uses certain protocols. A first transport connection for a first application protocol and a second transport connection for a second application protocol can be made between two proxies, wherein a client-side proxy is in communication with a client and a server-side proxy is in communication with a server, and the proxies use information from message payloads flowing between the client device and the server device over the first transport connection for acceleration of traffic over the second transport connection. Examples of transport protocols include a file server protocol and a storage access protocol. Cross-protocol acceleration can be expanded so that information obtained for one client on one protocol can be used to accelerate traffic for another client with the same or different protocol.

摘要： In a network including WAN accelerators and segment-oriented file servers, a method comprises responding to a client request to manipulate a file via a network file protocol by receiving a first request at a first WAN accelerator, wherein the request is a request to open a file located at a file server that is a segment-oriented file server, sending a local request for the file, corresponding to the first request, from the WAN accelerator to the file server, using a segment-aware network request protocol, returning at least a portion of the requested file in the form of a representation of a data map corresponding to the at least a portion of the requested file stored on the file server and using a data map for reconstruction of the requested file.

摘要： Network traffic information from multiple sources, at multiple time scales, and at multiple levels of detail are integrated so that users may more easily identify relevant network information. The network monitoring system stores and manipulates low-level and higher-level network traffic data separately to enable efficient data collection and storage. Packet traffic data is collected, stored, and analyzed at multiple locations. The network monitoring locations communicate summary and aggregate data to central modules, which combine this data to provide an end-to-end description of network traffic at coarser time scales. The network monitoring system enables users to zoom in on high-level, coarse time scale network performance data to one or more lower levels of network performance data at finer time scales. When high-level network performance data of interest is selected, corresponding low-level network performance data is retrieved from the appropriate distributed network monitoring locations to provide additional detailed information.

摘要： A method and apparatus are provided for scheduling a heterogeneous communication flow. A heterogeneous flow is a flow comprising packets with varying classes or levels of service, which may correspond to different priorities, qualities of service or other service characteristics. When a packet is ready for scheduling, it is queued in order in a flow queue that corresponds to the communication flow. The flow queue then migrates among class queues that correspond to the class or level of service of the packet at the head of the flow queue. Thus, after the head packet is scheduled, the flow queue may be dequeued from its current class queue and requeued at the tail of another class queue. If the subsequent packet has the same classification, it may be requeued at the tail of the class queue or may remain in place for another servicing round.
摘要翻译：提供了一种用于调度异构通信流的方法和装置。异构流是包括具有不同等级或级别的服务的分组的流，其可以对应于不同的优先级，服务质量或其他服务特征。当一个数据包准备好进行调度时，它会在与通信流对应的流队列中排队。然后，流队列在对应于在流队列的头部处的分组的类或服务级别的类队列之间迁移。因此，在头分组被调度之后，流队列可以从其当前类队列出队并在另一队列的尾部重新排队。如果后续分组具有相同的分类，则可以在类队列的尾部重新排列，或者可以保留在另一个维修周期的位置。

摘要： For an accelerated transaction, a client directs a request to a client-side transaction handler that forwards the request to a server-side transaction handler, which in turn provides the request, or a representation thereof, to a server for responding to the request. The server sends the response to the client via the server-side transaction handler and the client-side transaction handler. When data is to be sent between handlers, the sending transaction handler compares data segments with segments stored in its persistent segment storage and replaces segments with references to entries in its persistent segment storage that match or closely match the segments to be replaced. The transaction accelerators could handle multiple clients and/or multiple servers and the segments stored in the persistent segment stores can relate to different transactions, different clients and/or different servers. Persistent segment stores can be prepopulated with segment data from other transaction accelerators.
