Quality of Service

New Networking technologies, Services and Applications are all arriving on the market, each with an aim to deliver a Quality of Service (QoS) that is equal to or better than the legacy equipment.

Service providers and network operators have trusted brands, the maintenance of which is critical to their business. The challenge is to make new technology work in a way that meets customer expectations for quality, availability and reliability, while still offering network operators the flexibility needed to adapt quickly to new technology.

Quality of Service (QoS) parameters are a key factor in the roll-out of new technology. ETSI works on several QoS specifications and has been particularly active in Interoperability events on speech quality.

QoS parameters are increasing in importance as networks become interconnected and a large number of operators and providers interact to deliver communications.

3GPP™ Technical Specification Group SA2 covers Quality of Service requirements for access to both packet and circuit switched GSM and 3G networks.

ETSI TISPAN

TISPAN is the ETSI technical committee for fixed networks and for migration from switched circuit networks to packet-based networks with an architecture that can serve in both.

TISPAN is responsible for QoS studies in Next Generation Networks. The following TISPAN Working Groups address QoS:

• TISPAN WG1 - Cooperation with the ITU-T SG12 (QoS aspects)
• TISPAN WG3 - For QoS level provisioning and related control protocols
• TISPAN WG5 - Study and define QoS aspects in the customer network.

ETSI STQ

STQ is ETSI's technical committee for Speech, Transmission Planning, and Quality of Service.
