摘要： A method and system for extracting and building end-to-end route information in a multi-area Internet protocol (IP) autonomous system (AS) is disclosed. The method and system enable a user, such as a network administrator, to explicitly identify a full set of paths (links and routers) that a given IP packet would potentially traverse from its entry point in the source area of the AS where it originates until its exit point in its intended destination area.

摘要： A method and system for monitoring traffic and path information in a packet communication network operated according to an IP routing protocol is disclosed. The method and system enables a user, such as a network administrator, to explicitly identify a full set of paths (i.e., links and routers) that the traffic of a specific customer or set of customers, such as service providers hosted at a hosting site, is using when traversing the network. The system allows the dynamic monitoring of the set of active links carrying traffic belonging to the specific customer or set of customers, and the proportion of that traffic that is carried by each active link. This allows, among other things, the identification of network links that are critical for ensuring a high level of service to key customers.

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 and apparatus are provided for resource allocation with guarantees. A resource allocator is coupled to a controller. The resource allocator allocates resources between a plurality of arrival processes. A dedicated resource pool and a shared resource pool are provided. When an arrival process is identified, the resource allocator obtains a predefined characterizing value for the identified arrival process. Responsive to the obtained predefined characterizing value, resource from one of the dedicated resource pool or the shared resource pool is allocated to the arrival process. The controller is utilized for tracking resource use and for providing the predefined characterizing value for each of the plurality of arrival processes. The dedicated resource pool has a predetermined capacity greater than or equal to the total of all the low threshold values for each of the arrival processes. The dedicated resource pool provides the guarantees with the shared pool providing statistical multiplexed resource use. The controller increments a usage charge for the arrival process when a resource is allocated and decrements the usage charge at the end of use of the allocated resource. The controller evaluates use for the identified arrival process and updates the predefined characterizing value.

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 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.
