Variable Forward Error Correction For Optical Communication Links

View page
US Patent:
7930616, Apr 19, 2011
Filed:
Apr 12, 2007
Appl. No.:
11/786696
Inventors:
Ornan Gerstel - Los Altos CA, US
Loukas Paraschis - Palo Alto CA, US
Peter Lothberg - Los Altos CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H03M 13/00
US Classification:
714776
Abstract:
A method and system for setting a variable forward error correction overhead in an optical transport network frame for an optical link at a node are disclosed. In one embodiment, a method includes selecting a forward error correction overhead, signaling an optical node the selected forward error correction overhead, and setting the forward error correction overhead in the optical network transport frame for use in transmission of data over the optical link. In one embodiment, the forward error correction overhead is complementary to the data payload to maintain total transmission rate.

Sideband Filtering Of Directly Modulated Lasers With Feedback Loops In Optical Networks

View page
US Patent:
20060177225, Aug 10, 2006
Filed:
Feb 4, 2005
Appl. No.:
11/051699
Inventors:
Loukas Paraschis - Mountain View CA, US
James Theodoras - Plano TX, US
Ornan Gerstel - Los Altos CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04J 14/02
US Classification:
398087000
Abstract:
In a WDM optical network DML signals are sideband filtered to compensate for chirp with a feedback loop carrying signals from a monitor unit which helps maintain the sideband filter offset from a peak output of the DMLs. Network components with filtering characteristics, such as AWGs, can be used as the sideband filters. The monitor units monitor the Q-factors or BERs of the filtered signals and the sideband offset is maintained by temperature control of the sideband filters with respect to the DMLs.

Proactive Protection Mechanism Based On Advanced Failure Warning

View page
US Patent:
20080232244, Sep 25, 2008
Filed:
Mar 21, 2007
Appl. No.:
11/726225
Inventors:
Ornan Gerstel - Los Altos CA, US
Gabriele Maria Galimberti - Bovisio Masciago (MI), IT
Loukas Paraschis - Palo Alto CA, US
Anand Girish Parthasarathy - San Jose CA, US
Humayun Sohel - Santa Clara CA, US
Assignee:
Cisco Technology, Inc. - San Jose CA
International Classification:
H04J 3/14
US Classification:
370218
Abstract:
In one embodiment, an apparatus can include: (i) logic configured to detect an advanced warning indication, such as for a degraded signal condition, on a first link between first and second network devices, where the detection can utilize a number of corrected bits and forward error correction (FEC), for example; and (ii) logic configured to reroute packet traffic from the first link to a second link when the degraded signal condition is detected.

Variable Forward Error Correction For Optical Communication Links

US Patent:
20110167314, Jul 7, 2011
Filed:
Mar 10, 2011
Appl. No.:
12/932948
Inventors:
Ornan Gerstel - Los Altos CA, US

Peter Lothberg - Los Altos CA, US
Assignee:
CISCO TECHNOLOGY, INC. - San Jose CA
International Classification:
H03M 13/05
G06F 11/10
US Classification:

US Patent:
20210258665, Aug 19, 2021
Filed:
Dec 18, 2020
Appl. No.:
17/127248
Inventors:
- Annapolis Junction MD, US
Sanjoy Bardhan - Annapolis Junction MD, US
Sharfuddin Syed - San Jose CA, US
Biao Lu - Saratoga CA, US
Loukas Paraschis - Menlo Park CA, US
Hao Su - San Jose CA, US
International Classification:
H04Q 11/00
H04L 9/32
H04L 9/00
Abstract:
Methods and systems for secure autonomic optical transport networks are disclosed, including a method of adding a network element in an optical network, comprising: verifying, with a new network element, a first identifier certificate from a proxy network element; verifying, with the proxy network element, a second identifier certificate from the new network element; using a registrar for verifying the second identifier certificate from the proxy network element and sending domain specific parameters to the proxy network element for forwarding to the new network element; generating, on the new network element, a local certificate derived from a secure module and sending it to the proxy network element for forwarding to the registrar; enrolling, with the registrar, the new network element in the autonomic domain; and signing, with the registrar, the local certificate and sending the signed local certificate to the new network element.

In-Service Data Plane Encryption Verification

US Patent:
20200280566, Sep 3, 2020
Filed:
Feb 20, 2020
Appl. No.:
16/796733
Inventors:
- Redwood Shores CA, US
- Sunnyvale CA, US
Abhinava Sadasivarao - San Ramon CA, US
Radhakrishna Valiveti - Union City CA, US
Sharfuddin Syed - San Jose CA, US
Loukas Paraschis - Menlo Park CA, US
Assignee:
Oracle International Corporation - Redwood Shores CA
Infinera Corporation - Sunnyvale CA
International Classification:
H04L 29/06
G06F 21/60
Abstract:
A method of executing in-session encryption verification includes receiving a plurality of client data packets for transmission through a network; receiving one or more test data packets for verifying an encryption device; merging the client data packets and the one or more test packets into a data stream; selecting security parameters for each packet in the data stream based on a corresponding packet type; encrypting each packet in the data stream using the encryption device and the corresponding security parameters; and transmitting the data stream comprising encrypted packets through the network. The method also includes decrypting the encrypted packets at a receiving system using congruent techniques.
