Abstract

This document describes a remote presentation infrastructure. In an exemplary embodiment at least a portion of the data associated with a remote presentation session can be transported via a connectionless oriented channel established between a client and a remote presentation session. In an embodiment, a gateway computer system can be used to route data to and from a remote presentation session. In this embodiment, the gateway computer system can be configured to establish connectionless oriented channels and route data between remote presentation sessions and clients over connectionless oriented channels. In addition to the foregoing, other techniques are described in the claims, the attached drawings, and the description.

Claims

1. A computer-readable storage medium including instructions that upon execution by a processor cause a computer system to:

receive a connection request via a datagram addressed to a public network address of the computer system, the datagram addressed from a client network address for a client, the datagram including a resource network address for a remote presentation session in a payload;

associate the client network address with a private network address for the computer system and the resource network address;

receive first data for the remote presentation session, the data addressed to the private network address; and

send the first data via a connectionless oriented channel to the client network address in response to determining that the private network address is associated with the client network address.

2. The computer-readable storage medium of claim 1, further comprising instructions that upon execution cause the computer system to:

determine that second data received via the connectionless oriented channel from the client is addressed from the client network address; and

send the second data to the resource network address in response to determining that the client network address is associated with the private network address.

3. The computer-readable storage medium of claim 1, further comprising instructions that upon execution cause the computer system to:

receive a second connection request via a second datagram addressed to the public network address of the gateway, the second datagram addressed from a second client network address for a second client, the second datagram including the resource network address in a payload; and

associate the second client network address with a second private network address for the computer system and the resource network address.

4. The computer-readable storage medium of claim 1, the first data being indicative of a graphical user interface from the remote presentation session.

5. The computer-readable storage medium of claim 1, the first data being indicative of audio from the remote presentation session.
