IP Network Parameters
3.3 IP Network Parameters
3.3.1 Quality of Service (QoS)
The QoS technology based on layer 2 and the two QoS technologies Diffserv and TOS/IP Pre-
cedence based on layer 3 are allowing the VoIP application to request and receive predictable
service levels in terms of data throughput capacity (bandwidth), latency variations (jitter), and
delay.
3.3.1.1 Layer 2 / 802.1p
QoS on layer 2 is using 3 Bits in the 802.1q/p 4-Byte VLAN tag which has to be added in the
Ethernet header.
The CoS (class of service) value can be set from 0 to 7. 7 is describing the highest priority and
is reserved for network management. 5 is used for voice (RTP-streams) by default. 3 is used
for signaling by default.
