Abstract

Methods, apparatus, and computer program products are disclosed for facilitating access to one or more services in a network environment. At a host, a request is received from a client machine in communication with the host over a network. An asynchronous service description file indicates one or more asynchronous communication techniques configured to be performed to access or communicate with a service over the network. The asynchronous service description file is a conversion of a synchronous service description file indicating one or more synchronous communication techniques for accessing or communicating with a synchronous service. The asynchronous service description file is provided to the client machine.
