Display protocol interception in the network for services and network-based multimedia support for VDI

摘要

An apparatus and related method are provided for improving the performance of virtual desktop services. A network device is deployed in a network to intercept packets of a control session initiated by a client with a connection broker to obtain data from a host. The network device initiates a new control session to the connection broker on behalf of the client. The network device receives host information from the connection broker, replaces address information of the network device for the host information in a control session message and sends the control session message to the client. The network device establishes a data session with the client, initiates a data session with the host on behalf of the client and relays data between the data session with the host and the data session with the client such that the network device is transparent to the client and the host.

1. A method comprising:
at a network device: intercept packets of a control session initiated by a client between the client and a connection broker to obtain data from a host; terminating the control session between the client and the connection broker and initiating a new control session with the connection broker on behalf of the client; replacing client address information with address information of the network device such that the network device presents itself as the client to the connection broker; in response to initiating the new control session, receiving a control session message from the connection broker indicating host information; replacing the host information with the address information of the network device in the control session message and relaying the control session message to the client; storing data mapping the client to the host; receiving from the client a connection request message for a data session with the host and establishing a data session with the client, wherein the data session is multimedia streaming; based on the data mapping the client to the host, initiating a data session with the host on behalf of the client and relaying data between the data session with the host and the data session with the client such that the network device is transparent to the client and the host, wherein the connection broker is not in a data path of the data session with the host and of the data session with the client, wherein the network device is configured to modify the data session with the host on behalf of the client to provide service-level functions to the data session including quality of service, offloading data flows associated with the data session and computing a protocol specific performance characterization of the offloaded data flows; replicating multimedia data from a multimedia source; and sending the multimedia data to multiple clients.
