VoIP QoS - Quality of Service

The VoiceHost broadband network supports QoS and heres how

The VoiceHost broadband network supports QoS levels 1 - 4 and our entire core honours QoS from 3rd Party networks providing the correct markings have been applied and kept thoughout the transmissions.
QoS cannot make a lossy connection non-lossy, nor remove jitter, but if packet-loss and jitter arise from modest congestion or packets being delayed respectively, QoS can help.

CS3 | VoiceHost QoS

The CS (Class-Selector) codepoints above are in the form ‘xxx000′. The first three bits ‘xxx’ are the IP precedence bits for backwards compatibility, while the last 3 bits are set to zero. Each IP precedence value is mapped to a DiffServ value known as Class-Selector codepoints. If a packet is received from a non-DiffServ aware router that used IP precedence markings, the DiffServ router can still understand the encoding as a Class-Selector codepoint.
The DiffServ model also introduced two types of forwarding classes : AF & EF.

EF | VoiceHost QoS
The EF (Expedited Forwarding) traffic is often given strict priority queuing above all other traffic classes. The design aim of EF is to provides a low loss, low latency, low jitter, end-to-end expedited service through the network. These characteristics are suitable for voice, video and other real-time services.
