Selectively disabling reliability mechanisms on a network connection

Abstract

Computerized methods, systems, and computer-storage media for establishing and managing a transmission control protocol (TCP)-based tunnel ("tunnel") are provided. The tunnel spans between a data center and a private enterprise network and connects endpoints, of a service application, that reside in each location. During communication, the endpoints transmit data packets over one or more channels (e.g., higher-level channel and lower-level channel) that comprise the tunnel. Each of the channels supports reliability mechanisms (e.g., congestion-control mechanism and loss-recovery mechanism) integrally running thereon, for ensuring complete data-packet delivery. To prevent unwarranted performance degradation caused by duplicative efforts of reliability mechanisms, a fabric controller is employed to selectively disable one or more of the reliability mechanisms individually. The selective disablement of the reliability mechanisms is invoked by predefined criteria, such as instructions from a service model or detected identity of a source / destination endpoint, and is invoked on a per network connection basis.

Description

Background technique [0001] Large-scale networked systems are common platforms used in a variety of settings for running applications and maintaining data for business and operational functions. For example, a data center (eg, physical cloud computing infrastructure) can simultaneously provide multiple services (eg, web applications, email services, search engine services, etc.) to multiple customers. These massively networked systems typically include a large number of resources distributed throughout the data center, where each resource resembles a physical machine or a virtual machine running on a physical host. When a data center hosts multiple tenants (such as customer programs), these resources are optimally allocated from the same data center to the different tenants. [0002] Customers of a data center often require business applications running in a private enterprise network (eg, servers managed by customers geographically remote from the data center) to interact wi...

Problems solved by technology

[0004] When a TCP-based connection is run on top of another TCP connection, the interaction between these mechanisms used by the inner TCP connection and the outer TCP connection can lead to exaggerated retransmissions and flow throttling, which in turn leads to Significant drop in performance of the entire connection
