Patent number: 11799778Abstract: A network device may receive a packet and may determine whether a next header of the packet is an Internet protocol (IP) header, an Internet control message protocol (ICMP) header, or a segment routing header. The network device may determine, when the next header of the packet is the IP header, whether policy processing of the packet is set to ultimate segment decapsulation and may discard the packet when the policy processing of the packet is not set to ultimate segment decapsulation. The network device may decapsulate an outer header of the packet when the policy processing of the packet is set to ultimate segment decapsulation and may process the packet after decapsulating the outer header of the packet, to generate a processed packet. The network device may forward the processed packet toward a destination.Type: GrantFiled: October 11, 2022Date of Patent: October 24, 2023Assignee: Juniper Networks, Inc.Inventors: Sri Karthik Goud Gadela, Swamy Sadashivaiah Renu Kananda, Jamsheed R Wania, Alex Baban, Amit Kumar Shrivastava, Mohan Tatineni

Publication number: 20230327974Abstract: A first network device may receive an advertisement that includes a prefix for a second network device, wherein the advertisement is destined for a third network device. The first network device may determine, based on a network topology, whether a next hop is one hop away or multiple hops away. The first network device may selectively modify the advertisement to include a first segment identifier, based on the next hop being one hop away and to generate a first modified advertisement, or may modify the advertisement to include a second segment identifier, based on the next hop being multiple hops away and to generate a second modified advertisement. The first network device may forward the first modified advertisement or the second modified advertisement toward the third network device.Type: ApplicationFiled: June 1, 2023Publication date: October 12, 2023Inventors: Kiran KUSHALAD, Rajendra Prasad BOLLAM, Rajesh Shetty MANUR, Salih K A, Shraddha HEGDE, Sri Karthik Goud GADELA, Swamy Sadashivaiah KANANDA

Patent number: 11611506Abstract: This disclosure describes techniques that include determining, at an egress node in an SRm6 network, how to process a packet that may arrive without a segment routing header and/or a compressed routing header. In one example, this disclosure describes a method that includes receiving, by an egress node of a segment routing network, segment routing advertisements; configuring, by the egress node and based on the segment routing advertisements, information enabling the egress node to recognize encapsulated packets arriving at the egress node without a compressed routing header; receiving, by the egress node, a packet that does not have a compressed routing header; and de-encapsulating, by the egress node and based on the stored information, the packet.Type: GrantFiled: October 9, 2020Date of Patent: March 21, 2023Assignee: Juniper Networks, Inc.Inventors: Sri Karthik Goud Gadela, Swamy Sadashivaiah Renu Kananda, Ronald P.

Patent number: 11323371Abstract: This disclosure describes techniques for using Operations, Administration, and Management (OAM) operations when routing packets using micro SIDs in segment routing. For example, a network device comprises one or more processors configured to: receive a packet; determine whether the packet is encapsulated with one or more micro segment identifiers (SIDs); in response to a determination that the packet is not encapsulated with one or more micro SIDs, determine whether the packet has reached a segment routing tunnel endpoint; and in response to a determination that the packet has reached the segment routing tunnel endpoint, initiate Operations, Administration, and Maintenance (OAM).Type: GrantFiled: January 28, 2021Date of Patent: May 3, 2022Assignee: Juniper Networks, Inc.Inventors: Sri Karthik Goud Gadela, Swamy Sadashivaiah Renu Kananda, Ronald P.

Patent number: 11070464Abstract: The techniques describe forwarding multicast traffic using a multi-level cache in a network device forwarding plane for determining a set of outgoing interfaces of the network device on which to forward the multicast traffic. For example, a multi-level cache is configured to store a multicast identifier of a multicast packet and multicast forwarding information associated with the multicast identifier, such as identification of one or more egress packet processors of the network device to which the multicast packet is to be sent for forwarding to the set of one or more egress network devices, and/or outgoing interfaces of the network device toward each egress network device of the set of one or more egress network devices. The multi-level cache is also configured to store respective multicast identifiers that are to be encapsulated with outgoing multicast packets that are forwarded to the set of one or more egress network devices.Type: GrantFiled: October 16, 2018Date of Patent: July 20, 2021Assignee: Juniper Networks, Inc.Inventors: Sri Karthik Goud Gadela, Sharmila Koppula, Babu Singarayan, Sunanda L.
