Extensible network traffic engineering platform for increasing network resiliency in cloud applications

Abstract

The invention discloses an extensible network traffic engineering platform for increasing network resiliency in cloud applications. In various examples, an extensible network traffic engineering platform monitors network traffic and application performance to dynamically update network ingress and egress communication paths for increasing performance of the application such as a cloud gaming application, a cloud virtual reality (VR) application, and / or another high performance application types. Pluggable, distributed, application-centric network monitors, policy engines, and network configurators are implemented at the edge to detect degraded network and application performance and dynamically update network routing to account for the same.

Description

Background technique [0001] Network streaming applications such as cloud gaming, cloud virtual reality (VR), remote workstations, and / or other application types can be extremely sensitive to network performance parameters such as latency, jitter, and packet loss. Routing of network traffic on the Internet is often facilitated using the Border Gateway Protocol (BGP), but BGP is not delay, loss or congestion aware, causing network traffic to be frequently directed on sub-optimal paths. For example, network traffic directed on sub-optimal network paths (eg, via any number of autonomous systems (ASs)) can affect the quality of the application experience, reducing the responsiveness of the game due to lag, latency, stuttering, dropped frames, etc. [0002] A conventional method for routing traffic is to have multiple connections with two or more different Internet Service Providers (ISPs), so that when one ISP goes down, another ISP can be utilized to maintain the connection.

Problems solved by technology

However, these network monitors are not application-specific nor pluggable, thereby reducing their effectiveness and scalability for optimizing network traffic routing on a per-application basis

Thus, network traffic updates can reroute traffic in a manner that satisfies the monitor's criteria, but said criteria can actually result in a net reduction in quality of service (QoS) for a particular application because the monitor is not tailored to handle application-specific data and / or make network routing updates in favor of supported application types
