  • Enhancement to the IS-IS protocol for eliminating unwanted network traffic
    Patent number: 11962603
    Abstract: Systems and methods for enhancing a routing protocol of a telecommunications network are provided. In one embodiment, a method for enhancing the Intermediate System to Intermediate System (IS-IS) routing protocol is provided. The method includes receiving a packet from a first peer device on a network; determining whether a mismatch exists in an authentication of the packet from the first peer device; and responsive to an authentication mismatch, sending a flush instruction to a plurality of peer devices on the network to remove any link state packets from the first peer device. The plurality of peer devices are configured to remove all link state packets from the first peer device regardless of a type of authentication and a type of mismatch.

  • Enhancement to the IS-IS protocol for eliminating unwanted network traffic
    Patent number: 11252162
    Abstract: Systems and methods for enhancing a routing protocol of a telecommunications network are provided. In one embodiment, a method for enhancing the Intermediate System to Intermediate System (IS-IS) routing protocol is provided. The method includes the steps of determining if a password on a received Link State Protocol data unit (LSP) is authenticated and determining if the LSP is generated by an authenticated node. If the LSP password is not authenticated or the LSP is not generated by an authenticated node, the method further includes the step of setting a lifetime expiration timer of the LSP to zero.
