BT Ethernet
Ethernet is now the established and ubiquitous data interface and transport protocol
used in the local and private network. With the increasing use of Ethernet as the
origin and termination of data traffic across Local and Wide Area Networks (LAN
and WAN), the cost of ownership is rising for customers using existing data product
services. This is due to the high cost of interfacing LAN/ WAN router and switch
equipment using G703 or X21 data interfaces compared to that of a direct Ethernet
connection, known as the adaptation cost.
BT Wholesale Ethernet (BTW Ethernet) meets the requirements of customers looking
to provide an Ethernet option with full UK coverage for short, medium and long distance
data applications. Future plans also involve connectivity to BT's Global Ethernet
platform.
BTW Ethernet Service Overview
BTW Ethernet is an access and backhaul service allowing connection into the customer's
core network Points of Presence.
Since its launch in 2008, the geographic coverage has grown from the 106 Metro (EEA)
nodes being enabled, to 604 total nodes via deployment of Ethernet Edge Switches
(EES). Additional nodes will be deployed through subsequent rollouts (as detailed
in the 21CN Data Sets available from www.btwholesale.com. Click on Applications
then Networks and enter the NIPP area). The ultimate aim is to have full geographical
availability with the vision of 'any time, any place, anywhere'.
The service provides transparent, symmetrical, un-contended or contended (at 5:1)
bandwidth between two Ethernet ports in a point-to-point, point-to-multipoint or
meshed configuration. It is a flexible bandwidth, connection-oriented Ethernet data
service enabling customers to link two or more of their sites together across the
UK for data applications at defined 'Etherflow' bandwidths from 1Mbit/s through
to 1Gbit/s and 'Etherway' fibre access speeds of 10Mbit/s, 100Mbit/s and 1000Mbit/s.
'Etherway Copper' access speeds range from 1Mbit/s to 10Mbit/s.
A resilient access option, Etherway Protected 1, between the BT serving node and
the customer NTE (single interface presentation) can also be provided for both 100Mb
and 1000Mb access speeds at an additional cost.
Further enhancements will include 10Gb Etherway access speeds and Etherway Protected
2 based upon Openreach RO2 offering.
BTW Ethernet will be engineered for an end-to-end target availability of 99.93%
a maximum one way latency of <10ms, a maximum jitter of <3ms, and will come with
a maintenance package within tariff and be subject to BT standard terms and conditions
for BTW Ethernet.
The core network will be engineered to meet the availability and Quality of Service
(QoS) targets defined using automatic rerouting on failure as required. The target
end-to-end availability for BTW Ethernet using Etherway Protected access is 99.97%.
Each BTW Ethernet service will consist of two local access ends and a core link
between BT nodes where required. A Service Reference will be used to identify each
component including the customer's end-to-end Ethernet Virtual connection.
The number of remote sites connected to a single aggregate presented site will be
limited for practical reasons to 120 connections for 10BaseT and FE (100Mb) access
and 400 sites for Gigabit Ethernet fibre access and interface presentation. Up to
10,000 components can be allocated to any single network structure. A component
is considered to be an Etherway or Etherflow.
