IPVPN in a class of its own
ntl:Telewest Business extends its class of service to a new
level
Our converged solutions have now been enhanced to provide
eight Classes of Services across the IPVPN portfolio.
This develpoment now means we offer a greater Class of Service
choice than any other UK communications provider*.
The new Class of Service offering is available
immediately on all dedicated ntl:Telewest Business IPVPN services,
which range in speed from 64 Kilobits-per-second (kbps) to 1
Gigabit-per-second (Gbps). Demand for greater granularity of
traffic prioritisation is primarily being driven by large corporate
and public sector organisations. Many of these organisations use
ntl:Telewest Business’ own Ethernet
circuits to access the IPVPN service, and these access options have
been available nationwide since November 2006.
Having eight Classes of Service enables
organisations to ring-fence their most critical network traffic,
such as the data created by different types of core business
management systems, from other less crucial traffic.
“We've turned up the heat in the UK business
communications sector by taking Class of Service to a new level,”
said MD Stephen Beynon. “Communications are the lifeblood of the
modern organisation and customers increasingly want highly specific
prioritisation of their network traffic.
“With eight Classes of Service we enable them
to assign higher priorities to the likes of video and core business
management applications than email and web browsing traffic. This
puts customers in much greater control of how their information is
carried over networks, depending on its importance,” said Mr
Beynon.
The eight Classes of Service are:
- Real Time 1: Voice media (real time). These are typically
variable rate ‘inelastic’ applications that require low jitter and
loss, plus very low delay. Normally these are Voice over IP (VoIP)
and sensitive video applications that do not have the ability to
change encoding rates, or to mark packets with different importance
indications.
- Real Time 2: Video media (real time). This is recommended for
delay-sensitive and jitter-sensitive video applications such as
IPCCTV.
- Customer Control: This is best suited for peer-to-peer and
client-server signalling and control functions, using protocols
such as SIP, SIP-T, H.323, H.248 and Media Gateway Control Protocol
(MGCP).
- Application 1: Multimedia video conferencing, which are not
purely real-time in nature, or business-critical applications.
- Application 2, 3 and 4: Business-critical applications. These
three classes are best suited for applications that require
bandwidth and loss guarantees but have a reasonable level of
tolerance for jitter and latency. The application classes are
equivalent to each other in terms of priority; however each can be
guaranteed bandwidth independently of one other.
- Standard: The Standard service class is for applications that
have not been identified as requiring differentiated treatment and
is often referred to as best effort.
