Switching equipment for performing a switching operation for a high-speed packet in broadband Integrated Services Digital Network

Abstract: Switching equipment in provided for performing a switching process of a fixed length cell consisting of data and a cell header. A line interface provided in the switching equipment accommodates a plurality of lines and, at the same time, processes the data from each line on a cell unit. The line interface includes individual units and a common unit. The individual units are individually connected to the plurality of lines accommodated therein and individually process the cells. The common unit is connected to the individual units and, at the same time, effects batch-processing of the cells processed by the individual units.

Custom service control system

Abstract: In a custom service control system connected to a communication system including a plurality of user terminals and an exchange, a first memory stores service management processes respectively provided for the user terminals. A second memory stores a plurality of service processes respectively providing communications services. The service management processes includes pieces of custom data showing service processes respectively usable by the user terminals. A control unit selects service processes in response to requests from the user terminals in accordance with the service management processes.

Allocated and dynamic bandwidth management

Abstract: An ATM network switch and method of utilization for adaptively providing integrated services therein is disclosed. In providing such integrated services, if the allocated bandwidth for one connection has been consumed, or if the connection is not entitled to allocated bandwidth, the connection can optionally use dynamic bandwidth arbitration, or a combination of both allocated and dynamic. The switch includes an input port processor, a bandwidth arbiter, and an output port processor. Cells are transmitted from the input to the output, under the control of respective port processors and the bandwidth arbiter. Flow control is implemented on a per-connection basis. Individual queues are then assigned to traffic type groups in order to provide traffic type flow control. Based upon prioritization information associated with the cell at the input, cells are prioritized and transmitted from the output, with each cell maintained in the same order, relative to other cells on a connection, in which it was received.

Method and system for enabling queue camp-on for skills-based routing

Abstract: In an automated call management method and system, automated processing is used to collect customer information that enables skills-based call routing and a camp-on approach to efficiently handling calls. The customer information is preferably acquired through use of a web-compatible form that is submitted by the customer. The form includes information that identifies agent attributes that are considered advantageous to handling a particular call, includes the callback telephone number, and may include the time at which the callback should be initiated. In another embodiment, the information is acquired using interactive voice recognition techniques. After an agent queue is selected on the basis of a correlation between identified agent attributes and the skills of a particular agent or agent group, a camp-on request is generated to initiate a connection when an appropriate agent is available.

Asynchronous transfer mode based service consolidation switch

Abstract: An asynchronous transfer mode (ATM) based service consolidation switch (10) includes an input/output module (22) having a to-switch port (TSPP) processor (90) and a from-switch port processor (FSPP) (92). The TSPP (90) and the FSPP (92) communicate with a bandwidth arbiter (114), multipoint topology controllers (116), and a data crossbar (117) on a switch control module (32). The TSPP (90) receives traffic over links for conversion into an internal cell format. Internal cells are buffered until allowed to transfer to an appropriate FSPP (92). Multipoint topology controllers (116) performs translations for internal switch flow control through interactions between the TSPPs (90), FSPPs (92), and the bandwidth arbiter (114). The bandwidth arbiter (114) performs appropriate bandwidth arbitration to allow internal cells to flow from TSPPs (90) to FSPPs (92) over the data crossbar (117).

Hierarchical resource management with maximum allowable allocation boundaries

Abstract: A system for managing resources such as buffers and bandwidth which are allocated to competing entities through two or more levels in a telecommunications network is disclosed. The system provides a tool to allocate resources for use by individual entities. Each entity may be assigned a Minimum -- Guaranteed variable and a Maximum -- Allowed variable. When an entity requests resources the system determines if the entity is using its respective minimum guaranteed resource allocation which is specified by the Minimum -- Guaranteed variable. If the entity is not using its respective minimum guaranteed resource allocation, the system allocates a resource unit to the requesting entity. The system also allows a requesting entity to use additional resource units above the resource allocation specified by the Minimum -- Guaranteed variable, provided such resource units are available. If the entity has reached its respective minimum guaranteed resource allocation, but has not reached the respective maximum allowed resource allocation specified by the Maximum -- Allowed variable and no intervening level is using its respective maximum allowed resource allocation, then a resource unit is allocated to the requesting entity.

Frame classification using classification keys

Abstract: An improved method and apparatus for recognizing, classifying and processing frames received at a frame processor in a computer network is disclosed. Following receipt of a frame at an input port of a frame processor, source and destination addresses are parsed from the frame. A plurality of lookup tables are provided in a memory, each of which contains a search field and a classification key field. Source or destination addresses are stored in the respective search fields along with other information associated with the frame and a compact classification key is stored in the corresponding classification key field. Searches are performed of the respective search fields within the respective lookup tables to determine whether a match exists between the each of the destination and source addresses and other information and the search field within the lookup tables. In the event the searches yield a match, a classification key associated with each respective address is retrieved. Classification keys corresponding to addresses thus retrieved are concatenated and the concatenated value is employed as the basis for a further search of the search field of another one of the lookup tables to identify a classification key which is employed to specify the manner of further processing of the received frame.
