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, intercepting packets of a control session initiated by a client between the client and a connection broker to obtain data from a host; initiating a new control session to the connection broker on behalf of the client; receiving host information from the connection broker; replacing address information of the network device for the host information in a control session message and sending the control session message from the network device to the client; storing at the network device data that maps the client to the host; receiving at the network device 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; the network device 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; replicating multimedia data from a multimedia source; and sending the multimedia data to multiple clients.
