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: 11849381Abstract: A cellular data communication network includes a gNodeB connected to a UPF by an IP network. A first translation module translates GFP packets into IP packets transmitted over the IP network. A second translation module translates the IP packets back into IP packets and forwards the IP packets to the UPF. A PFCP proxy snoops information and provides it to a BGP module that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF. The BGP module may program the first translation module with an SR policy associated with a binding SID that is bound to an interface to the gNodeB. The SR policy may invoke translation according to a function. The routing module may be programmed to embed GTP information in an SRH header that is used by the first translation module. BGP module may also distribute routing and VPN updates.Type: GrantFiled: June 29, 2021Date of Patent: December 19, 2023Assignee: Arrcus Inc.Inventors: Keyur Patel, Tetsuya Murakami

Patent number: 11539615Abstract: Disaggregated border gateway protocol (BGP) enables an eBGP session between an internal node an external node to continue despite failover of a perimeter through which the eBGP session is established. eBGP control traffic is trapped by a perimeter router and forwarded to a BGP speaker on the internal node through an IP tunnel. Failover is detected in response to a change in a source address of the IP tunnel over which eBGP control traffic is received. The BGP speaker announces routes to the external node that include a reference to an internal address of an active perimeter router. In response to failover, the BGP speaker announces updated routes referencing the standby router for the perimeter router.Type: GrantFiled: October 23, 2020Date of Patent: December 27, 2022Assignee: ARRCUS INC.Inventors: Tetsuya Murakami, Kalyani Rajaraman, Keyur Patel
