US Patent:

8081639, Dec 20, 2011
Filed:

Aug 18, 2009
Appl. No.:

12/583267
Inventors:

Lawrence D. Weizeorick - Lisle IL, US
Bruce R. Zelle - Naperville IL, US
Steven T. DeLong - Woodridge IL, US
Assignee:

Tellabs Operations, Inc. - Naperville IL
International Classification:

H04L 12/28
H04J 3/06
US Classification:

37039562, 370503
Abstract:

Clock recovery is used in a variety of communications network applications to enable nodes using different clocks to operate in an effectively synchronized manner. Example embodiments of the present invention include an apparatus and corresponding method for supporting client data transport with timing transparency and require neither a common clock to be available at both the ingress and egress sides of the connection nor overhead bytes to recover a client clock. Rather, client traffic clock recovery may be performed in example embodiments of the present invention entirely in the egress data path using the client data received from the ingress side after removing the clients signal from a higher level carrier signal.

US Patent:

48721590, Oct 3, 1989
Filed:

Mar 31, 1988
Appl. No.:

7/175546
Inventors:

Jayant G. Hemmady - Naperville IL

Assignee:

American Telephone and Telegraph Company AT&T Bell Laboratories - Murray Hill NJ
International Classification:

H04J 326
US Classification:

370 60
Abstract:

A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024. times. 1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator.

Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second.

International Classification:

Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched.

The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user.
