Class of Service network performance guarantees
BT is leading the market with the prioritisation and partitioning of voice, multimedia and data applications
The market is demonstrating a growth voice, multimedia and data traffic that require various performances with service level guarantees. As a result, BT has launched a 6 Class of Service (CoS) model for both its UK and global MPLS platforms to address this growing trend in the growth of multiple applications used by customers including:
-
Increasing use of (multiple) ERP applications to support critical business processes
-
Increasing use of and interest in IP Telephony and streaming video applications LANs becoming more sophisticated. Quality of Service (QoS) mechanisms being introduced in customer networks
-
Differential Services (‘DiffServ’) de facto standard for CoS implementations
The 6 CoS model is outlined below:
| Application Class of Service |
Application Examples |
|
Voice
A any-to-any IP service capable of delivering Voice over IP applications for those customers wishing to construct "do it yourself" voice solutions. Underwritten by installation, availability, round trip delay, packet delivery and jitter Service Level Agreements.
|
IP Voice
|
|
Multimedia
Optimised to support real-time video applications, the Multimedia class is underwritten by Service Level Agreements on Installation, Availability, Round Trip Delay and Packet Delivery. A maximum of four Assured Data classes (see below) are available when the Multimedia class is ordered.
|
Video conferencing, video streaming
|
| Assured Data (up to 4 applications or mix of multimedia applications)
Up to four Assured Data classes are available for mission-critical or delay-sensitive data applications. Each critical data application can be assigned to a dedicated Assured Data class allowing bandwidth to be dedicated to individual critical data applications. This prevents critical data applications having to compete for the same bandwidth and ensures the performance of each application. Assured Data classes are an any-to-any IP service underwritten by Installation, Availability, Round Trip Delay and Packet Delivery Service Level Agreements.
|
Mission critical, delay sensitive applications such as
- Oracle
- SAP
- ERP
- Data Warehousing
- Critrix
- Client Server
- Multimedia applications
|
|
Standard Data
A basic any-to-any IP transport service for delay-tolerant data applications such as e-mail or intranet access. The Standard Data class is underwritten by Installation, Availability and Round Trip Delay Service Level Agreements.
|
Delay tolerant applications such as
- Internet/Intranet Browsing
- File transfers
- Other applications that can accommodate variable throughput delay
