Abstract: Described is an improved approach to ensure high availability for established sessions (e.g., application layer sessions) over network connections that negotiates and renegotiates encryption keys (e.g., TLS/SSL) at clean boundaries to ensure in-transit data are properly handled during migration of an application (e.g., a reverse proxy server instance). Connected TCP sessions may be handed off to another application (e.g., from existing proxy server to new/upgraded proxy server) and after establishing a new TLS session with a new encryption key, data transfer may be resumed between a client and a server using the new/upgraded application in a client-server architecture.

Abstract: Some embodiments are directed to an improved approach to implement deployments where a client can get application-level redirects to different servers, where the service is running in a different cloud environment. Dynamic port mapping may be performed at runtime. Routes may be added to IP tables to implement redirects from a first cloud to a second cloud.

Abstract: A computer program product, system, and computer implemented method for application-level redirect trapping and creation of NAT mapping to work with routing infrastructure for private connectivity in cloud and customer networks. The approach disclosed herein generally comprises a method of leveraging a reverse connection endpoint and IP address mapping controller to capture redirection messages from a private cloud or network (e.g., a service consumer network or a service consumer hybrid cloud). This allows at least the IP address mapping controller to manage a cloud networking infrastructure to provide for a service provider network (e.g., a public cloud) to support applications that overcome the isolation requirements of a private cloud or network to perform useful work. For example, without saddling the private cloud or network user with a heavy pre-configuration burden, the approach disclosed herein supports redirection to dynamically determined IP addresses at the private cloud or network.

Abstract: The present disclosure relates generally to establishing a connection between a client and an endpoint in a manner that reduces network latency. In an example, a network layer proxy receives a request of a client for an endpoint connection establishment, the request including endpoint information. The network layer proxy sends, to an application layer proxy, the endpoint information, the endpoint information sent using a connection-less protocol. Thereafter, the network layer proxy receives, from the application layer proxy, a network address of an endpoint selected by the application layer proxy based on the endpoint information and application layer information. The network layer proxy sends a response to the client such that a connection is established to the endpoint using a connection-based protocol and such that the connection bypasses the application layer proxy.
