International Classification:

G01R 31/08

US Classification:

370218, 370390

Abstract:

Packet switch operating methods and packet switches, using first processing circuitry of the packet switch, configure different second processing circuitry of the packet switch to periodically transmit control packets to a destination device via a port of the packet switch and, subsequent to the configuring and using the second processing circuitry, transmit the control packets to the destination device via the port during moments in time when the first processing circuitry is non-operational. Other packet switch operating methods and packet switches, using first processing circuitry of the packet switch, specify a configuration for a control packet processing procedure implemented by different second processing circuitry of the packet switch, communicate the configuration to the second processing circuitry, and using the second processing circuitry, transmit control packets according to the control packet processing procedure, the control packet processing procedure being configured according to the configuration.

Appl. No.:

11/595684

Inventors:

Dackary R. Busch - Veradale WA, US
Kevin Q. Daines - Liberty Lake WA, US

Loren Douglas Larsen - Spokane Valley WA, US

International Classification:

H04J 1/16

US Classification:

370252, 370401

Abstract:

This document describes tools that communicate an operational state of a transport service. The transport service provides connectivity between two or more networks, enabling the networks to exchange packets. The tools detect an operational state of a transport service. After doing so, the tools may convey the operational state of the transport service to at least one of the networks through a user-to-network interface port of a network interface device, send a message to a network interface device requesting that the network interface device convey the operational state to a network connected to the network interface device, or configure a network interface device to communicate the operational state.

International Classification:

H04L 12/26

US Classification:

370216, 3702362

Abstract:

Systems and methods with dynamic Connectivity Fault Management (CFM) and Continuity Check Messages (CCMs) that enable dynamic configurations to avoid limitations associated with static reconfigurations. Variously, a network, a method, and a network element are configured to implement a dynamic CFM method for dynamic notifications and actions taken based thereon between Maintenance End Points (MEPs). The systems and methods may also include a CCM attribute adjustment method between two MEPs, a CCM suspension and/or resumption method between two MEPs, and a MEP auto-discovery and leaving method. Advantageously, the systems and methods may be utilized in a variety of contexts including controlled maintenance, in-service software upgrades, network congestion, discovery of new remote MEPs, and the like to enable dynamic configurations between MEPs. The systems and methods may also apply to Carrier Ethernet, Multiprotocol Label Switching-Transport Profile (MPLS-TP), and the like.

Appl. No.:

13/489633

Inventors:

Marc HOLNESS - Nepean, CA
Kelly D. FROMM - Newman Lake WA, US
Cory D. GORDON - Colbert WA, US

Assignee:

CIENA CORPORATION - Linthicum MD

International Classification:

H04L 12/26

US Classification:

3702411

Abstract:

A Carrier Ethernet method includes receiving a request to initiate an Ethernet Operations, Administration, and Maintenance (OAM) session at a local device, setting up the OAM session at the local device responsive to the request, transmitting a Protocol Data Unit (PDU) from the local device to a remote device with information related to the OAM session and the request contained therein, and receiving the PDU at the remote device and setting up the OAM session at the remote device based on the information in the PDU. The OAM session can include Ethernet Frame Loss Measurement and can be initiated only at the local device without requiring operator involvement at the remote device

International Classification:

H04L 12/24
H04L 12/26
H04L 29/12
H04Q 11/00

Abstract:

Systems and methods of automatically creating and operating a Maintenance End Point (MEP) include, at a slave/reactive network device, receiving an Operations, Administration, and Maintenance (OAM) Protocol Data Unit (PDU) with a destination Media Access Control (MAC) address equal to an interface address of the slave/reactive network device; automatically creating the MEP based on the received OAM PDU and attributes contained in a header of the OAM PDU, wherein the MEP is with a master/active network device; and operating an OAM session with the master/active network device including exchanging Continuity Check Messages (CCMs) with an interval learned from received CCMs from the master/active network device. The systems and methods can further include automatically deleting the MEP responsive to failing to receive any OAM PDUs from the master/active network device during the operating for a predetermined time.

International Classification:

H04L 12/26

Abstract:

A method for measuring frame loss on a connection between a near-device (NED) and a far-end device (FED). The method includes: placing, on the connection, multiple test frames having a plurality of sequence numbers; obtaining, from the connection, a first reflected test frame having a first sequence number, a first FED receiving counter value from the FED, and an initial FED received count from the FED; obtaining, from the connection, a second reflected test frame having a second sequence number, a second FED receiving counter value from the FED, and the initial FED received count from the FED; and calculating a one-way frame loss value on the connection based on the second sequence number and the initial FED received count.

International Classification:

H04L 12/26

Abstract:

Ethernet fault management systems and methods using programmable Type-Length-Value (TLV) offsets combine software-based Operations, Administration, and Maintenance (OAM) protocol support with hardware-based fault management support to delegate generation and processing of OAM protocol messages to hardware devices with the software-based protocol support used to program hardware based on fixed offsets in the OAM protocol messages. The hardware can be designed to be flexible since the hardware can be agnostic to the logic within the OAM protocol which would reside in the software. The Ethernet fault management systems and methods combine the flexibility of software-based approaches with the speed and efficiency of hardware-based approaches.
