摘要： A method of controlling packet traffic in an IP network of originating, receiving and intermediate nodes to meet performance objectives established by service level agreements. Traffic statistics and performance data such as delay and loss rates relating to traffic flows are collected at intermediate nodes. A control server processes the collected data to determines data flow rates for different priorities of traffic. A static directory node is used to look up inter-node connections and determine initial traffic classes corresponding to those connections. The rates are combined with the initial traffic classes to define codes for encoding the headers of packets to determine their network priority.

摘要： The present invention is an apparatus for controlling client node access to data items maintained in a storage device. The data items include volatile data items. The apparatus comprises a communication device for communicating with multiple client nodes; and a processor, coupled to the storage device for polling the client nodes to exchange (e.g., retrieve and/or transmit) data related to the volatile data items, via the communication device. The processing system further controls client node access to the data items of the storage device. In this way, the apparatus and method of the present invention remedies the problems associated with directory server overload.

摘要： A method of providing a rate guarantee to individual or groups of flows in a router through intelligent management of buffers. Rate guarantees are provided by intelligently allocating and isolating the buffers available to each flow. In its most basic form, the method applies to output queued network devices with a simple FIFO scheduler, where a number of streams some with rate reservations are sought to be multiplexed onto an outgoing link. The method involves strictly partitioning the buffer into portions strictly reserved for each flow in proportion to its link reservation. This ensures that each stream obtains the link reservation rate in a scalable manner. A particular embodiment of the invention allow for a portion of the buffer to be strictly partitioned while allowing streams full access to the remainder of the buffer. Other embodiments utilize the use of a link scheduler to divide bandwidth amongst a number of queues, while using buffer management to facilitate bandwidth amongst a number of flows in each queue.

摘要： A method, apparatus, computer product and structure is presented for representing and managing large amounts of information concerning networks of elements. While being useful for communication networks, it can be also usefully deployed in the context of other networks such as distribution and transportation networks. The method uses a hierarchical construct called “catalog”—a set of elements (which could be “atomic” elements or catalogs themselves)—to organize information about physical or abstract entities relevant for modeling the network. A matrix construct whose rows and columns constitute such elements are used to model connections at different levels of abstraction. A common framework and representation provided using these two constructs is shown to be useful for visualization, administration, configuration, modeling, monitoring and manipulation of the network.

摘要： The present invention addresses the issue of controlling delay variations (jitter) in packet-switched networks by enhancing the capabilities of existing scheduling policies. The idea is to use a few bits in the header of packets to send jitter control information to the downstream network elements, so that the delay variation caused by the upstream network element, is compensated for by the downstream network element. The key point to observe is that packets (or cells in ATM) may be small, and therefore, not contain many bits in the header that can be used for jitter control. We describe a unique scheme, that utilizes the bits that are available for jitter control in an efficient manner, allowing for the desired jitter to be obtained with as few bits as possible.
摘要翻译：本发明通过增强现有调度策略的能力来解决分组交换网络中的延迟变化（抖动）的控制问题。想法是在报文头中使用几个比特来向下游网元发送抖动控制信息，从而使上游网元产生的延迟变化由下游网元补偿。要观察的关键点是分组（或ATM中的小区）可能很小，因此在报头中不包含可用于抖动控制的多个位。我们描述了一种独特的方案，它以有效的方式利用可用于抖动控制的位，从而允许以尽可能少的位获得所需的抖动。
