Explanation:
RTP or TCP IP header compression is a mechanism that compresses the IP header in a data
packet before the packet is transmitted. Header compression reduces network overhead and
speeds up transmission of RTP and TCP packets.
Cisco IOS software provides a related feature called Express RTP/TCP Header Compression.
Before this feature was available, if compression of TCP or RTP headers was enabled,
compression was performed in the process-switching path. Compression performed in this manner
meant that packets traversing interfaces that had TCP or RTP header compression enabled were
queued and passed up the process to be switched. This procedure slowed down transmission of
the packet, and therefore some users preferred to fast-switch uncompressed TCP and RTP
packets.
Now, if TCP or RTP header compression is enabled, it occurs by default in the fast-switched path
or the Cisco Express Forwarding-switched (CEF-switched) path, depending on which switching
method is enabled on the interface. Furthermore, the number of TCP and RTP header
compression connections was increased.
If neither fast-switching nor CEF-switching is enabled, then if TCP or RTP header compression is
enabled, it will occur in the process-switched path as before.
The Express RTP and TCP Header Compression feature has the following benefits:
1. It reduces network overhead.
2. It speeds up transmission of TCP and RTP packets. The faster speed provides a greater benefit
on slower links than faster links.
