Appl. No.:

12/772771

Inventors:

Pankaj Shukla - San Jose CA, US
Manish Gupta - San Jose CA, US

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

H04L 12/26

US Classification:

3702411, 370216, 370217, 370 22, 370242, 370248

Abstract:

An example network system includes a layer two (L2) device and a layer three (L3) device. The L2 device includes a control unit is configured to determine a preferred network path from a first L2 network in which the L2 device resides to an intermediate L3 network in which the L3 device resides that couples the first L2 network to a second L2 network having a second L2 device. The control unit includes a management endpoint (MEP) module. The MEP module executes an operations, administration, and management (OAM) protocol to monitor the first L2 network and output an L2 frame in accordance with the OAM protocol to the L3 device to notify the L3 device that it is within the preferred network path. A MEP module of the L3 device executes an OAM protocol that outputs L2 frames to the L2 device indicating the status of the L3 network.

International Classification:

H04J 1/16

US Classification:

3702411, 370245

Abstract:

In general, techniques are described for simultaneously testing connectivity to same or different remote maintenance endpoints of the same maintenance association. Specifically, a network device may include a control unit that simultaneously executes both a first and a second maintenance session. The control unit maintains first and second session identifiers that uniquely identifies the first and second maintenance sessions. The control unit receives via the first maintenance session input that specifies parameters for a maintenance message and generates the maintenance message in accordance with the parameters such that the maintenance message includes the first session identifier. The network device also includes an interface card that forwards the maintenance message to another network device in order to determine connectivity between these two network devices. By generating the maintenance message to include the first session identifier, the control unit may upon receiving a response to the maintenance message resolve to which of the maintenance session the response corresponds.

International Classification:

H04L 12/26

US Classification:

370218

Abstract:

Data traffic loss in a an Ethernet Ring that is multihomed, in an active-standby manner, to a VPLS transport network (such as a Border Gateway Protocol (BGP) multihomed Ethernet Ring, an MC-LAG multihomed Ethernet Ring, or some other type of active-standby multihomed Ethernet Ring, etc.) (ring) is avoided. The exemplary multihomed ring running Ethernet Ring Protection (ERP) protocol includes a Ring Protection Link (RPL), a first node and a second node linked with a designated border router and a standby border router of the network, respectively. The data traffic loss in the multihomed ring is avoided by (i) receiving an indication that the link between the first node and the designated border router has failed; and (ii) invoking, responsive to the received indication, an ERP Media Access Control (MAC)-flush in the ring, even in the absence of a failed link in the ring and without activating the specified RPL. The ERP MAC-flush causes subsequent data packets from each of the plurality of nodes in the ring to be forwarded to the standby border router via the second node.

US Classification:

3702411, 370242, 370252, 370401

Abstract:

In general, techniques are described for preparing a computer network for planned events. A network device comprising a control unit and an interface implements these techniques. The control unit is configured to be a member a maintenance association that verifies connectivity a single service instance. The interface outputs a maintenance message to an additional network device to verify connectivity between the network device and the additional network device. The control unit receives an indication to initiate a planned event capable of disrupting the maintenance association. Prior to the control unit performing the planned event, the interface generates a modified maintenance message indicating that the planned event will be performed by the network device. The interface then transmits the modified outgoing maintenance message to the additional network device to direct the additional network device to avoid detecting the planned event as a connectivity fault.

International Classification:

H04L 12/741

Abstract:

A cloud service provider's enterprise edge device and network interface are configured to establish a single tunnel connection with a remote server for delivering data packets to multiple distinct virtual machines on the remote server. The provider's enterprise edge device stores the network address information for each virtual machine and remote server to attach the destination network addresses to the data packet for transmission to the appropriate virtual machine on the remote server. Utilizing a single tunnel to transmit data packets to multiple virtual machines increases scalability at the provider's enterprise edge device and reduces system resources compared to other implementations in which the provider uses a tunnel for each virtual machine on a remote server.
