How Can This Be Useful on My Network?
If you are planning to implement on VoIP on circuit speeds less than 768 Kbps,
LFI is indispensable, in an AVVID environment where your network is a true
multiservice network and has data and video in addition to voice packets. At
speeds below this, the MTU of an IP/Ethernet packet (1500 bytes) will take
more than 15 ms to serialize. If you are really interested in good quality voice
transmissions, you need to use some kind of priority queuing like LLQ as well. If
your link speed is small, you will also obtain significant gains by another link efficiency
mechanism, RTP header compression.We will consider that next.
