Bermuda network topology
The Bermuda project name orginates from the triangle of connectivity
provided by the network between Southampton, UCL and Lancaster,
though the acronym also represents "Bringing Enhanced Routing to
Multimedia Users in Distributed Academia".
The links used the JANET Managed Bandwidth Service (MBS), which enabled the
three links to be established over ATM PVCs at a 2Mbit/s maximum data rate.
The SuperJANET network has since been upgraded to SuperJANET4, which currently has no equivalent to the
previous MBS. As a result, the connections are being converted to tunneled
IPv6in-IPv4 connections. Methods to restore native connectivity are
being sought.
The diagram also show's BT Exact's IPv6 Trial network, to which Southampton
connected (via UCL) during its participation in the 6INIT project.
UKERNA is currently considering methods to expand the IPv6 trial to any
interested UK academic site. A roadmap for deployment should be produced
by November 2001. It is expected that the extended deployment will peer
with Internet 2 (probably at the 6TAP) and
European and Japanese IPv6 networks.
