QUALITY OF SERVICE FOR VOICE

entire end-to-end 200–ms delay budget for voice traffic.Here are two causes of serialization delay:• The encoding process and the codec used. For instance, the G.729 codec, which is a type ofcompression that enables voice to be coded into 8-kbps streams, has an alg[r]

Switch Port Membership Modes • Switch ports are Layer 2-only interfaces associated with a physical port. A port can be configured to support these VLAN types: • Static VLAN - Ports on a switch are manually assigned to a VLAN. • Dynamic VLAN - This mode is not widely used in production networks and i[r]
