摘要： An exclusive VCC is maintained between each two communicating work stations (MT pair). The handoff method differs if the MT moves to a coverage area having a base station connected to the same switch as the previous coverage area (intra-switch mobility) or to a coverage area having a base station connected to a different switch than the previous coverage area (inter-switch mobility). In intra-switch mobility, the switch changes the path directly to the new base station and eliminates the path through the original base station. In inter-switch mobility, the switch performs the path set-up. The path may be elongated from the switch connected to the original BS, to the new BS, rather than from the original BS to the new BS. This eliminates the path through the original base station. The exclusive VCC between the MT pair permits path elongation to be minimized.

摘要： A method and system are disclosed for constructing a power spectrum based connection admission control table and using such a table in a communications network, such as an ATM network. Power spectrum parameters, such as the power spectrum DC component .gamma., half power bandwidth B.sub.w and average power .PSI..sub.w are transformed to .gamma., an equivalent half power bandwidth B.sub.e and an equivalent average power .PSI..sub.e, where B.sub.e is a predetermined constant. Since B.sub.e is constant, the transformation reduces the memory requirements for constructing a connection admission control table.

摘要： A system and process are provided for controlling congestion at a node of an asynchronous transfer mode (ATM) communications network. The process and system utilize fuzzy logic in determining whether or not to "admit," i.e., allocate a virtual channel (VC) for, new communications (or calls) to the node. Fuzzy logic is also use to control the rate cells are transmitted to the node for communications already "admitted," i.e., for which a VC has already been allocated. The fuzzy logic rules for bandwidth estimation in admission control may be developed from an "equivalent capacity" model. The fuzzy logic rules for adjusting cell transmission rates may be developed from a "two-threshold" congestion control model.

摘要： A method and system for providing system security services is disclosed. The server of a vendor of a content inspection engine receives a current set of definition data in a first format from the server of a definition data file generator through a network. The vendor and the definition data file generator are two unaffiliated legal entities. Then the server of the content inspection engine vendor makes available the definition data to be used by a network device via the network. The network device utilizes the content inspection engine and the definition data in a second format that the content inspection engine recognizes in its unmodified state to provide system security services to a number of devices that are attached to the network device.

摘要： A shared memory management mechanism and method for a high-speed network releases network packets efficiently and maintains the requirement of First In First Out. A series of linked lists including a linked list for each output queue and a linked list of used broadcast packets aids a buffer manager in efficiently managing the buffers in the shared memory. The linked lists include a special data format that encodes the broadcast status, links, and whether the next entry in the list is for unicast or broadcast frames. A scanning procedure scans the broadcast status to efficiently release the broadcast frame buffers. A dynamic scanning procedure consumes less bandwidth than the scanning procedure to efficiently release the broadcast frame buffers.

摘要： A scheme for arbitrating access to a data bus shared among a plurality of competing sources is provided. Each competing source is assigned an adjustable priority weighting value (PWV) which is initially set to an initial value based on the bandwidth requirements of the competing source. During arbitration, the PWVs of those competing sources requesting access to the bus are compared, and the competing source with the smallest PWV is granted access. The PWV of the competing source which was granted access to the bus is reset to its initial value and the PWV of each competing source which requested, but was denied, access is reduced by one for subsequent comparisons. The arbitration scheme of the present invention is further applied to two-level arbitration. Each competing source is classified into a competing source group, and the requests from the grouped competing sources are processed by first level arbitration. First level arbitration passes one competing source for each group to a second level arbiter. The second level arbiter compares the PWVs of the competing sources resulting from first level arbitration to determine the competing source with the smallest PWV, and adjusts the PWVs after access to the bus has been granted.
摘要翻译：提供了一种用于仲裁访问多个竞争源之间共享的数据总线的方案。每个竞争源被分配有可调优先权重值（PWV），其基于竞争源的带宽需求被初始设置为初始值。在仲裁期间，比较了请求访问总线的竞争源的PWV，允许访问具有最小PWV的竞争源。允许访问总线的竞争源的PWV重置为其初始值，并且请求但被拒绝访问的每个竞争源的PWV减少一个用于随后的比较。本发明的仲裁方案进一步适用于两级仲裁。每个竞争源被分类为竞争源组，来自分组竞争源的请求通过一级仲裁处理。第一级仲裁将每个组的一个竞争源传递给第二级仲裁器。第二级仲裁者比较由一级仲裁产生的竞争源的PWV，以确定具有最小PWV的竞争源，并且在访问总线之后调整PWV。
