Feature Transparency In A Telecommunications Network

View page
US Patent:
6650632, Nov 18, 2003
Filed:
Jun 30, 1998
Appl. No.:
09/106449
Inventors:
Lev Volftsun - Herndon VA
Clay H. Neighbors - Reston VA
Fred R. Rednor - Arlington VA
Andrew West - Leesburg VA
Adrian Kingston - Sterling VA
Mikhail Rabinovitch - Herndon VA
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04L 1228
US Classification:
370352, 370465
Abstract:
An auxiliary communication network is introduced into a virtual private network for passing signaling messages that present features not supported by the public, primary communication network portion of the virtual private network. Protocol converters are positioned within the virtual private network to intercept signaling messages, establish a connection through the auxiliary network, determine whether the intercepted messages present unsupported features, and, in which case, route corresponding feature requested through the auxiliary communication network. Preferably, the auxiliary network connection is established in a direction reverse to and in response to the primary network connection.

Overload Reduction In A Communication System

US Patent:
6707792, Mar 16, 2004
Filed:
Jun 30, 1998
Appl. No.:
09/107839
Inventors:
Lev Volftsun - Herndon VA
Clay H. Neighbors - Reston VA
Fred R. Rednor - Arlington VA
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04L 1266
US Classification:
370235, 370352, 370389, 370467, 379229, 379265, 709103, 709310
Abstract:
A method and apparatus for reducing overload conditions of a node of communication system is disclosed. One or more pairs of predefined upper and lower overload threshold values are stored. A rejection proportion value is stored in association with each of the pairs of overload threshold values. Messages arrive at the node and are processed by it. The current processing load or saturation level of the node is continuously measured in real time. The current saturation level is associated with one of the predefined pairs of overload threshold values. The node rejects a number of messages equal to the rejection proportion value that is associated with the overload threshold values that correspond to the current saturation level. Preferably, only call initialization messages, such as call setup messages or initial address messages, are rejected. Accordingly, the node rejects those messages which, if acknowledged, would lead to the creation and transmission of numerous other messages and would worsen the overload condition.

Universal Protocol Conversion

US Patent:
6741610, May 25, 2004
Filed:
Aug 16, 1999
Appl. No.:
09/375844
Inventors:
Lev Volftsun - Herndon VA
Clay H. Neighbors - Reston VA
David S. Turvene - Arlington VA
Fred R. Rednor - Arlington VA
Anatoly V. Boshkin - Herndon VA
Mikhail Rabinovitch - Herndon VA
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04J 316
US Classification:
370466
Abstract:
A scalable, programmable software based application run on a programmed general purpose digital computer is used for interconnecting a plurality of heterogeneous network nodes. The application has the ability to convert between any two signaling protocols used, such as those used over a telecommunications network, by converting an originating protocol to a universal non-protocol specific representation, and then converting the universal non-protocol specific representation to a receiving protocol. A call context is used to store information elements created from the originating protocol so that a universal call model applies inter-working rules. The universal call model is also in communication with state machines associated with both the originating and the terminating sides in order to supply the appropriate response signals anticipated by the originating and terminating sides received when each is in communication with its own protocol. As such, the universal call model allows both the originating and terminating sides of a call to operate independently of each other by virtue of the fact that each side deal through the universal call model and not directly with the side for which the protocol message is being converted. Therefore, any protocol is easily converted to any other protocol by first translating the protocol message to the universal protocol non-specific format.

US Patent:
7187651, Mar 6, 2007
Filed:
Mar 3, 2004
Appl. No.:
10/792957
Inventors:
Lev Volftsun - Herndon VA, US
Clay H. Neighbors - Reston VA, US
Fred R. Rednor - Arlington VA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04L 12/66
H04L 12/28
H04J 3/22
G06F 9/00
US Classification:
370235, 370352, 370389, 370467, 709103, 709310
Abstract:
Reducing overload conditions of a node of communication system comprises storing one or more sets of overload range values, where each set represents a range of used capacity of a component of the node. A rejection proportion value is stored in association with each of the sets of overload range values. Messages arrive at the node and are processed by the node. The current processing load or saturation level of the node is continuously measured in real time. The current saturation level is associated with one of the overload ranges. The node rejects a number of messages equal to the rejection proportion value that is associated with the overload range that corresponds to the current saturation level. In an embodiment, only call initialization messages, such as call setup messages or initial address messages, are rejected. The node may be a call processor in a telecommunication network, such as a universal protocol converter.
