Patent number: 11909664Abstract: A segment identifier (SID) manager interfaces with clients by way of a library. Clients implementing network services and needing SIDs according to internet SRv6, are allocated blocks by the SID manager using the library. Clients assign SIDs from the block independent of the SID manager using the library. Where a threshold portion of the block is assigned, the library requests an additional block of SIDs from the SID manager. Clients transmit context mappings of assigned SIDs to the SID manager for use by administrators and to enable recovery in the event of failure.Type: GrantFiled: January 5, 2022Date of Patent: February 20, 2024Assignee: Arrcus Inc.Inventors: Keyur Patel, Kalyani Rajaraman, Ravindra Vaishampayan, Derek Man-Kit Yeung, Lalit Kumar, Tetsuya Murakami, Matthew Anderson

Patent number: 10671590Abstract: Aspects of the embodiments are directed to synchronizing at least a portion of a link-state database. A network element can lose an adjacency. The network element can transmit a request to a neighboring network element for synchronization of a link-state database. The request can include a version number of a last synchronized link-state database from the neighboring network element. The neighboring network element can determine whether the version of the link-state database is greater than or less than a copy of the link-state database stored by the neighboring network element. If the requested version number is less than the neighboring network element's link-state database version number, then the neighboring network element can send changes to the link-state database since the requested link-state database version number.Type: GrantFiled: September 1, 2016Date of Patent: June 2, 2020Assignee: Cisco Technology, Inc.Inventors: Alfred C.

Patent number: 10432757Abstract: Message summarization and flood suppression may be provided. A proxy (e.g., an IGMP Proxy) process may be used to reduce the flooding of messages (e.g., IGMP messages) over a network (e.g., an EVPN network). A triggering process may also be provided for provider edge (PE) devices to setup their underlay multicast tunnels. The proxy may comprise two components: i) a proxy for reports (e.g., IGMP reports); and ii) a proxy for queries (e.g., IGMP Queries).Type: GrantFiled: July 26, 2018Date of Patent: October 1, 2019Assignee: Cisco Technology, Inc.Inventors: Ali Sajassi, Samir Thoria, Ravindra Nandalal Rathi, Keyur Patel, Derek Man-Kit Yeung
