Embodiment Construction

[0016] review

[0017] According to one or more embodiments of the present disclosure, an electronic device maintains one or more tunnel-based overlays for a communication network. The communication network includes two or more physical provider networks. The device maintains a mapping between one or more overlays of the communication network and specific applications. The device adjusts a mapping between one or more overlays of the communication network and a specific application. The device causes one or more routers in the communications network to route traffic for a particular application according to an adjusted mapping between one or more overlays of the communications network and the particular application.

Abstract

The invention relates to an intelligent wide area network (IWAN). In one embodiment, an electronic device maintains one or more tunnel-based overlays for a communication network. The communication network includes two or more physical provider networks. The device maintains a mapping between a particular application and the one or more overlays for the communication network. The device adjusts the mapping between the particular application and the one or more overlays for the communication network. The device causes one or more routers in the communication network to route traffic for the particular application according to the adjusted mapping between the application and the one or more overlays for the communication network.

Description

technical field [0001] The present disclosure relates generally to computer networks, and more specifically, to techniques for implementing intelligent wide area networks. Background technique [0002] Enterprise networks carry a rapidly growing volume of business and non-business-critical traffic. Typically, business applications (eg, video collaboration, cloud applications, etc.) use the same Hypertext Transfer Protocol (HTTP) and / or HTTP Secure (HTTPS) technologies used for non-business-critical web traffic. This complicates the task of optimizing network performance for specific applications, since many applications use the same protocol, making it difficult to differentiate and select traffic for optimization. [0003] As the number of business and non-business critical applications grows, so does the number and variety of service level agreements (SLAs) available to the network. In general, an SLA refers to a target or threshold level of performance guaranteed by a n...
