摘要： A fast and scalable pattern making engine is presented. The engine represents variations on a Shift-And method capable of matching patterns in data streams having high speed data rates. In one aspect of the invention high speed is achieved by accessing the pattern RAM in parallel. In another aspect, the input is likened to TDM and individual slots or channels are accessed separately. The two aspects can also be combined to provide a scalable and high speed pattern matching engine. The engine is adaptable to streams of known length or more complex expressions such as regular expressions with arbitrary length.

摘要： A selective, flow-based datapath architecture is described. A Flow Control Block Manager (FCBM) is located in a flow-based datapath for selectively and intelligently processing packets in the Flow Path. If, according to the FCBM, efficiency gains can be achieved by creating a flow control block and employing flow-based processing on a packet stream, the packets are processed accordingly. If, however, insufficient gains are anticipated the packets are processed in a flow-unaware manner. The FCBM determines the manner in which to process packets based on a set of criteria.

摘要： A frame work to build and use a generic content switch is provided. The applications and the routing policy for the content switch are provided by the application provider. The content switch, however, is managed by a network provider so that there is a clear separation of the switching action and the switching policy. The basic framework consists of two key elements; a content switch and a user-defined application that also contains the switching policy.

摘要： The resilient packet ring (RPR for short) is receiving much attention as a telecommunications network architecture. The RPR consists of dual counter-rotating ringlets and implements a ring protection scheme such as ring wrap and source steering. Topology discovery is an important aspect of the network management of the RPR. Herein described is a new topology discovery algorithm which performs in multiple phases. According to one phase of the algorithm, a station on the ring periodically exchange with only its neighboring stations a control messages containing a topology database. The topology database indicates addresses of stations on the ring and their link status. The algorithm should find applications not only in RPR but also other ring architectures.

摘要： A method and system for logical group endpoint discovery in a data communication network is disclosed. A network endpoint receives from a source a request identifying a logical group and determines whether a port associated with the endpoint is a member of the logical group. If a port associated with the endpoint is a member of the logical group, the endpoint transmits to the source a reply identifying the port and the logical group. The request may be multicast while the reply may be unicast. The logical group may be a VLAN or a multicast group. The source and endpoint are preferably 802.1ag maintenance endpoints. The request may include an IEEE 802.1ag continuity check multicast address as a destination address.

摘要： A binary-tree-based arbitration system and methodology with attributes that approximate a Generalized Processor Sharing (GPS) scheme for rendering fairer service grants in an environment having a plurality of competing entities. Arbitration based on probabilistic control of arbiter nodes' behavior is set forth for alleviating the inherent unfairness of a binary tree arbiter (BTA). In one implementation, BTA flag direction probabilities are computed based on composite weighted functions that assign relative weights or priorities to such factors as queue sizes, queue ages, and service class parameters. Within this general framework, techniques for desynchronizing a binary tree's root node, shuffling techniques for mapping incoming service requests to the BTA's inputs, and multi-level embedded trees are described.

摘要： A virtual router network (VRN) for performing real-time flow measurements (RTFM) is provided. The VRN effectively reduces the number of traffic metering points required thereby simplifying the aggregation and exportation of flow records to a collector. The collector may be service manager in a network management system. The metering points, in a preferred embodiment, are at virtual interfaces (VI) which are edge nodes in VRN. One of the virtual interfaces is selected as a master virtual interface and act as a collector and distributor of flow related information. In one aspect of the invention the VRN is used to provide, non-invasively, per-flow delay monitoring in a communication system.
