AW: global one vpn

Hi,

I do not know many specifics about GO Intranet VPN service.

I know from a reliable source, that the service was announced in August 1999
first, but could not be implemented due to software problems, so actually
October/November 1999 was the date of establischment.

GO's VPN service is MPLS based, thats true, but I think it is based on CISCO
Tag Switching rather than true MPLS.

I had a project, where a customer wanted to replace its leased line backbone
an required high bandwidth. GO is restricted to 2 Mbps access speed, which
was not sufficient in this project. So if you consider GO, ask about
possible access speeds.

GO uses "MPLS", but does a few month ago not consider IPSec for its service,
so encryption and authentication can not be supported by GO. Ask this also,
if still philosophy.

Hope this helps.

Chavdar,

I'm not sure specifically what Global One's service
actually is, but you should know that MPLS doesn't
specify encryption itself.

MPLS (Multi-Protocol Label Switching) is where an edge
device tags an IP packet so other MPLS-aware routers
can transparently route it like a VC, apply QoS to it,
and do other funky things.  It can almost appear like
a bridge since multiple hops through MPLS routers
appear to be like one hop from the edge device on one
end to the edge device on the other end.

If your requirements of a VPN include encryption,
message integrity, and authentication, then MPLS alone
won't do it.

That said, however, many companies (inlcuding my own)
are building MPLS backbones to enable QoS and SLAs for
encrypted VPN traffic.

In that case, rate the service on the merits of the
VPN solution itself and drive hard into what their
MPLS network is really giving you.

Good luck.
Chris
