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 apparatus are provided for scheduling the transmission of cells of a plurality of data streams in a communications network. An earliest deadline first (EDF) scheduler is provided for scheduling the transmission of cells of a plurality of data streams in a communications network to ensure that the connection or data stream with the earliest deadline is transmitted first. Each of the multiple data streams has a delay bound or deadline. Data of each data stream is enqueued to a corresponding data cell queue. A timing wheel time slot based on an identified target transmission time for each data cell queue is calculated utilizing an addition of a maximum delay value. A move forward timing mechanism includes a scan forward feature to identify a succession of virtual connection or data stream cell queues for transmission. A multiple tier cell scheduler is provided that includes at least two scheduling timing wheels. The priority of a first timing wheel is higher than the priority of a second timing wheel. The priority of the second timing wheel is higher than the priority of an optional third timing wheel. The third timing wheel includes a best effort operational mode. The relative rates between data streams are maintained, while the absolute rates of the data streams are increased or decreased in the lowest priority wheel.

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 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.
