Fault Isolation For Communication Networks For Isolating The Source Of Faults Comprising Attacks, Failures, And Other Network Propagating Errors

View page
US Patent:
6442694, Aug 27, 2002
Filed:
Feb 27, 1998
Appl. No.:
09/031899
Inventors:
Ruth Bergman - Lexington MA
Muriel Medard - Champaign IL
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
G06F 1130
US Classification:
713201, 714 57, 709224
Abstract:
A technique for isolating faults in a communication network is described. The techniques can be utilized in high speed communications networks such as all-optical networks (AONs). The technique is distributed, requires only local network node information and can localize attacks for a variety of network applications. The technique is particularly well suited to the problem of attack propagation which arises in AONs. The technique finds application in a variety of network restoration paradigms, including but not limited to automatic protection switching and loopback protection and provides proper network operation reduced, or in some cases no data loss and bounded delay time regardless of the location of the attack or the physical span of the network. Since the technique is distributed, and its associated delays do not depend on the number of nodes in the network. Hence the technique avoids the computational complexity inherent to centralized approaches.

US Patent:
6507012, Jan 14, 2003
Filed:
Apr 30, 2001
Appl. No.:
09/845702
Inventors:
Muriel Medard - Champaign IL
Stephen R. Chinn - Westford MA
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H01J 4014
US Classification:
250225, 356 731, 25022717
Abstract:
Apparatus and techniques for detecting malfunctions, anomalies and attacks upon optical devices of a transparent all-optical network, including amplified links and optical nodes, of the network. A portion of an input signal of the optical device and a portion of an output signal from the optical device are coupled to an optical processing unit and a an optical to electrical signal converter. The electrical output signal of the converter is coupled to an electronic processing unit which generates a difference signal which is a function of the input and output signal portions for comparison to a predetermined set of parameters. The result of the comparison is an alarm signal indicative of the occurrence of a malfunction. Also described is an optical comparator capable of generating the difference signal which is indicative of perturbations in the optical device.

Method And Apparatus For Automatic Protection Switching

View page
US Patent:
6728205, Apr 27, 2004
Filed:
Feb 4, 1998
Appl. No.:
09/018354
Inventors:
Steven G. Finn - Framingham MA
Muriel Medard - Lexington MA
Richard A. Barry - Brookline MA
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H04L 1226
US Classification:
370217, 370400, 370254, 345440
Abstract:
A Bi-directional Link Self-healing Network (BLSN) for implementing bi-directional link automatic protection switching (APS) for an arbitrary edge or node redundant network and a technique for implementing APS recovery in response to an edge or node failure in a network is described. The BLSN technique does not require permanent allocation of spare capacity for each connection and allows sharing of capacity among many network connections by allocating capacity for use only in the event of a failure. The described technique allows loopback protection to be performed over node or edge redundant networks and operates such that the remains connected after the failure of a node or an edge in the network. The technique makes use of connected directed subgraphs of the network. Also described are techniques for generating the directed subgraphs on node and edge redundant networks having an arbitrary network topology.

Assignee:
Network Appliance, Inc. - Sunnyvale CA
International Classification:
H04L 12/28
US Classification:
370389
Abstract:
A method and apparatus for a communications network that executes a medium access control (MAC) protocol that permits multiple access to a shared medium or shared switching fabric. The MAC protocol uses a bandwidth allocator to regulate access to the network by sending a permission message to a node, allowing it to transmit to a specific set of nodes for a specific length of time. The medium and switching fabric can carry one or more protocols, each of varying framing format and native bitrate. The switching fabric provides a connection-oriented bufferless data transport service that preserves frame ordering. An illustrative embodiment uses a slotted master/slave time-division multiplexed access (TDMA) scheme to allow flexible provisioning of network bandwidth.

Assignee:
NetApp, Inc. - Sunnyvale CA
International Classification:
G01R 31/08
US Classification:
370216, 370242, 370404
Abstract:
A fiber-optic networking system that can survive a break in the fiber and restore full connectivity to all nodes in the network. The network can detect the presence of a cut in the fiber, locate the cut, recover from the cut, and restore the communication capacity that was available before the cut. The network is also capable of automatically determining the existence and identity of the nodes in the network, the distance of the node from the headend, and the executing procedures to handle both planned and unplanned (i. e. , during a fault) removal of nodes from the network.

Minimum-Cost Routing With Network Coding

US Patent:
7414978, Aug 19, 2008
Filed:
Dec 30, 2004
Appl. No.:
11/027889
Inventors:
Desmond S. Lun - Cambridge MA, US
Muriel Medard - Cambridge MA, US
Tracey Ho - Champaign IL, US
Ralf Koetter - Champaign IL, US
Niranjan Ratnakar - Urbana IL, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H04B 7/00
US Classification:
370238, 370396, 370390, 709232
Abstract:
A method and computer program product for performing minimum cost routing with network coding is presented. The method and system model a network as a directed graph. A cost per unit flow is associated with each link of the directed graph. A link capacity is associated with each link of the directed graph. A network code is then computed that sets up a routing connection that achieves an optimal cost using the cost per unit flow for each link of the directed graph and using the link capacity for each link of the directed graph.
