Patent number: 7904571Abstract: A method and apparatus for generating at least one aggregate (e.g., a set of aggregates) for a given area of a network such that the number of aggregates is minimized subject to a maximum acceptable path selection error are disclosed. One operational benefit of the present method is that network administrators can select aggregates for an area based solely on the topology of the area without worrying about remaining areas of the OSPF network. Another benefit is that the present method enables trade-offs between the number of aggregates and the bound on the path selection error.Type: GrantFiled: May 31, 2006Date of Patent: March 8, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Charles R. Kalmanek, Jr., Guangzhi Li, Aman M. Shaikh, Jennifer M. Yates, Dongmei Wang

Patent number: 5524116Abstract: A frame layer communications system for packet-switched virtual circuits that provides error detection when the link layer both corrupts and discards cells. An illustrative embodiment of the invention provides two error detection mechanisms: the first for the user-data and the second for certain control information. When the frame is segmented into cells, the control information and information relating to the second error detection mechanism are segmented into a single cell.Type: GrantFiled: June 30, 1995Date of Patent: June 4, 1996Assignee: AT&T Corp.Inventors: Charles R. Kalmanek, Jr., William T. Marshall

Patent number: 5519836Abstract: A method of on-line routing of permanent virtual circuits is disclosed. The method uses an exponential cost function based on the network state and virtual circuit parameters to determine paths for the virtual circuits without scaling. The method may also advantageously use information available when multiple virtual circuits are requested to determine paths for the virtual circuits. Additionally, the method allows the routing selection to be refined so that the total cost of routing all the virtual circuits is reduced.Type: GrantFiled: March 25, 1994Date of Patent: May 21, 1996Assignee: AT&T Corp.Inventors: Rainer Gawlick, Charles R. Kalmanek, Jr., Kajamalai G. Ramakrishnan

Patent number: 5502816Abstract: A method of routing a requested virtual circuit in a network advantageously uses information about concurrent requests for other virtual circuits. Each virtual circuit request in a set of concurrent requests is specified by one or more parameters and each virtual circuit request is routed as a function of one or more parameters of a plurality of the requests. Thereafter, the routing of each request in the set of requests is refined according to a cost function so that the total cost of routing is reduced.Type: GrantFiled: March 25, 1994Date of Patent: March 26, 1996Assignee: AT&T Corp.Inventors: Rainer Gawlick, Charles R. Kalmanek, Jr., Kajamalai G. Ramakrishnan

Patent number: 5272697Abstract: Apparatus and methods for time multiplexing a resource among a plurality of entities at average rates and with deterministic delays between accesses to the resource by an entity. An entity accessing the resource receives a time slot on the resource; a fixed number of time slots constitute a frame. Each entity receives a fixed allocation of time slots in the frame. When an entity has work for the resource to do, it receives access to the resource for a number of slots in each frame equal to the lesser of the number of slots required to do the work and the number of slots in the allocation. A rate-controlled server is disclosed which defines a frame and allocations therein, as well as a hierarchy of servers which combines rate-controlled traffic with best effort traffic. In the hierarchy, a rate-controlled server activates a round-robin server when the entities served by the rate-controlled server do not require all the slots in a frame.Type: GrantFiled: February 23, 1990Date of Patent: December 21, 1993Assignee: AT&T Bell LaboratoriesInventors: Alexander G. Fraser, Charles R. Kalmanek, Srinivasan Keshav

Patent number: 5014265Abstract: A method of controlling congestion in a virtual circuit packet network. A initial packet buffer is assigned to each virtual circuit at each node into which incoming packets are stored and later removed for forward routing. If a larger buffer is desired for a virtual circuit to service a larger amount of data, then additional buffer space is dynamically allocated selectively to the virtual circuit on demand if each node has sufficient unallocated buffer space to fill the request. In one embodiment, the criterion for dynamic allocation is based on the amount of data buffered at the data source. In alternative embodiments, the criteria for dynamic allocation may be further based on the amount of data buffered at each node for a virtual circuit and the total amount of free buffer space at each node of a virtual circuit. Signaling protocols are disclosed whereby data sources and virtual circuit nodes maintain consistent information describing the buffer allocations at all times.Type: GrantFiled: November 30, 1989Date of Patent: May 7, 1991Assignee: AT&T Bell LaboratoriesInventors: Ellen L. Hahne, Charles R. Kalmanek, Samuel P. Morgan

Patent number: 4841295Abstract: A local area data distribution system includes a plurality of data processing stations connected to a common bus. Individual data processing stations contend with each other for access to the bus while the bus is held at a predetermined and controlled but overridable logic state by applying their priority code bit by bit to the bus and comparing the logic state of the bus with the bit they are applying thereto. A biasing arrangement holds the bus at the predetermined and controlled logic state during the contention interval at a signal level that may be easily overridden by an output of any one of the individual data processing stations.Type: GrantFiled: July 24, 1986Date of Patent: June 20, 1989Assignee: American Telephone and Telegraph Company, AT&T Bell LaboratoriesInventors: Robert H. Delaney, Charles R. Kalmanek, Jr., Robert C. Restrick, III

Patent number: 4787082Abstract: In a local data distribution network configuration a plurality of bidirectional data distribution busses are each connected to a bus master control circuit at a terminal end of the bus. Connected to each of the data distribution busses are a plurality of passive outlets to which intelligent connectors or stations may be connected. Each station has a unique address and is utilized for individually coupling data processing devices to the bus. Grouped pluralities of the bus master control circuits are included within a bus termination hub facility. Data from any of the bus master control circuits may be transferred by the bus termination hub via a data trunk as part of a star type configuration, to a central switching circuit such as a virtual circuit switch. Direction of data flow on each of the bidirectional busses and periodic temporary synchronization of the stations is controlled in response to signals transmitted to the bus by the bus master control circuitry associated with that bus.Type: GrantFiled: July 24, 1986Date of Patent: November 22, 1988Assignee: American Telephone and Telegraph Company, AT&T Bell LaboratoriesInventors: Robert H.
