Abstract
Techniques allow an intermediate (IM) device to transparently intercept and dynamically modify signaling messages being exchanged by a client and a server when negotiating setup and delivery of a multimedia stream from a streaming server. The techniques also allow an IM device to dynamically convert the real-time multimedia stream from a first transport layer protocol to a second transport layer protocol, and the reverse, based on the particular topology of the network including the presence and location of any security devices that may block the multimedia stream. The IM device may be configured to dynamically modify messages intercepted between the client and the server to change a transport layer protocol indicated by the messages from the Transmission Control Protocol (TCP) to the User Datagram Protocol (UDP), and the reverse, and convert a UDP data stream to TCP packets and inject the TCP packets into an established TCP session.
