Patent number: 10291532Abstract: A network device may receive first route information from an Ethernet virtual private network (EVPN) device and/or a provider backbone bridging EVPN (PBB-EVPN) device. The network device may generate second route information based on the first route information. The network device may provide the second route information to permit network traffic to be transferred between the EVPN device and the PBB-EVPN device. The network device may receive the network traffic to be transferred between the EVPN device and the PBB-EVPN device after providing the second route information. The network device may modify the network traffic to be compatible with the EVPN device or the PBB-EVPN device after receiving the network traffic. The network device may provide the network traffic between the EVPN device and the PBB-EVPN device after modifying the network traffic.Type: GrantFiled: June 29, 2017Date of Patent: May 14, 2019Assignee: Juniper Networks, Inc.Inventors: Maruthi Kishore Tiruveedhula, Wen Lin

Patent number: 10110470Abstract: A device may receive a route identifier that includes a range identifier or a configuration identifier. The range identifier may identify a range of broadcast domain identifiers associated with a first device. The configuration identifier may identify an Ethernet segment identifier (ESI) configuration of the first device. The device may identify the range identifier or the configuration identifier included in the route identifier. The device may select a designated forwarder from among multiple devices based on the range of broadcast domain identifiers or based on identifying the configuration identifier. The designated forwarder may be the same designated forwarder selected by at least one other device.Type: GrantFiled: September 14, 2016Date of Patent: October 23, 2018Assignee: Juniper Networks, Inc.Inventors: Maruthi Kishore Tiruveedhula, Rukesh Dorai, Sudhin Jacob

Patent number: 9680734Abstract: Techniques include providing ingress protection for multipoint label switched paths (LSPs). According to the techniques, a primary ingress node and a backup ingress node of a network are both configured to advertise a virtual node identifier of a virtual node as a next hop for a multicast source. Two or more egress nodes of the network then use the virtual node as a root node reachable through the primary ingress node to establish a multipoint LSP. After the multipoint LSP is established, the primary ingress node forwards traffic of the multicast source on the multipoint LSP. When failure occurs at the primary ingress node, the backup ingress node forwards the traffic of the multicast source along a backup path and onto the same multipoint LSP with the virtual node as the root node reachable through the backup ingress node. The techniques enable ingress protection without tearing down the multipoint LSP.Type: GrantFiled: May 16, 2016Date of Patent: June 13, 2017Assignee: Juniper Networks, Inc.Inventors: Maruthi Kishore Tiruveedhula, Raveendra Torvi

Patent number: 9654386Abstract: An apparatus may include a processor and a control plane that directs the processor to (1) detect that at least a portion of an initial branch path of a point-to-multipoint label-switched path has failed over to a failover route that rejoins the initial branch path at a network node and (2) establish an alternate branch path that merges with the initial branch path at the network node. The apparatus may also include a network interface and a data plane that uses the network interface to transmit data via the alternate branch path, where after the data plane begins transmitting data via the alternate branch path, the control plane instructs the network node to forward data from the alternate branch path rather than from the failover route. Various other apparatuses, systems, and methods are also disclosed.Type: GrantFiled: May 9, 2016Date of Patent: May 16, 2017Assignee: Juniper Networks, Inc.Inventors: Raveendra Torvi, Vishnu Pavan Beeram, Maruthi Kishore Tiruveedhula

Patent number: 9363169Abstract: An apparatus may include a processor and a control plane that directs the processor to (1) detect that at least a portion of an initial branch path of a point-to-multipoint label-switched path has failed over to a failover route that rejoins the initial branch path at a merge-point device and (2) establish an alternate branch path that merges with the initial branch path at the merge-point device. The apparatus may also include a network interface and a data plane that uses the network interface to transmit data via the alternate branch path while data is still being transmitted via the initial branch path, where after the data plane begins transmitting data via the alternate branch path, the control plane instructs the merge-point device to forward data from the alternate branch path rather than from the failover route. Various other apparatuses, systems, and methods are also disclosed.Type: GrantFiled: March 31, 2014Date of Patent: June 7, 2016Assignee: Juniper Networks, Inc.Inventors: Raveendra Torvi, Vishnu Pavan Beeram, Maruthi Kishore Tiruveedhula

Patent number: 8953437Abstract: In general, techniques are described for performing a graceful restart for a computing network utilizing downstream on demand (DOD) label distribution. In one example, a method is provided that includes establishing a communication session for Label Distribution Protocol (LDP) that uses a downstream on demand label distribution mechanism for distributing labels. A first label mapping message is exchanged between two routers that defines at least a first label to be applied by an upstream router when forwarding one or more of the data packets to a destination. When the communication session fails, a forwarding state comprising the first label is preserved, and one or more data packets are forwarded based on the first label. The communication session is gracefully restarted. Once the communication session is reestablished, a second label mapping message is exchanged between the routers.Type: GrantFiled: January 4, 2012Date of Patent: February 10, 2015Assignee: Juniper Networks, Inc.Inventor: Maruthi Kishore Tiruveedhula
