Application Switching

Application switching, illustrated in figure B-4, also is capable of changing
bandwidth use, but the change is determined entirely by the type of application

Figure B-4
Application Switching diagram
In a system configured for application switching, the Remote site modem/router
looks for a packet in the data stream coming from the LAN that is configured
using the H.323 stack protocol and containing an H.225 signaling protocol. In
the illustration shown in Figure B-4, the signal is a voice call initiated at the
Remote site.
The packet is examined to determine the port number, then, from the allocated
port ranges, the modem/router determines the type of application being sent.
The modem/router sends a switch request to the VMS requesting a carrier for
the application type. Typical applications include:
• Video
