US 10735320

US Patent 10735320, titled "Application wire," was issued on August 4, 2020, from an application filed on August 8, 2019. The patent is currently assigned to K Mizra LLC, and the inventors are Ping Pan and Richard D. Gitlin.

Abstract:
The patent describes a method for managing data transfer in a Multiprotocol Label Switching (MPLS) network. At an MPLS node, information related to an application flow is identified from unencapsulated packet headers or an ingress data stream. Based on stored data that maps application flows to pseudowires, a plurality of pseudowires are determined for paths through the MPLS network. This stored data indicates a distributed mapping of the application flow via at least one of these pseudowires for a sending device application. Finally, data related to the sending device application is communicated via at least one of the determined pseudowires.

Plain-Language Overview of Independent Claims:

• Claim 1 (Method): This claim describes a process performed at a network node within an MPLS network. The method involves identifying data related to a specific application (an "application flow") by examining its unencapsulated packet headers or the incoming data stream. Once identified, the node uses pre-configured data that links application flows to "pseudowires" (virtual connections) to determine which pseudowires to use as paths through the MPLS network. A key aspect is that this pre-configured data allows for a "distributed mapping," meaning an application flow can be split and sent over multiple pseudowires. The method concludes by sending the application's data through one or more of these chosen pseudowires.

• Claim 8 (Device): This claim describes a physical device, such as an edge router, equipped with a processor and memory. The device is programmed to carry out the functions described in Claim 1. Specifically, it can identify application flow information from packet headers or data streams, determine appropriate pseudowires for distributed mapping of the application flow through an MPLS network based on stored mapping data, and then communicate the application's data using those pseudowires.

• Claim 15 (Computer-Readable Non-Transitory Medium): This claim covers a computer storage medium (like a hard drive or flash memory) that holds software instructions. When a processor executes these instructions, it performs the same method as described in Claim 1: identifying application flow information, determining a plurality of pseudowires for a distributed mapping of the application flow through an MPLS network based on stored data, and communicating the application data via those pseudowires.
