AS3561 - The SAVVIS backbone
network
- SAVVIS has engineered its network around a single
platform - AS3561 - which enables one global IP backbone,
rather than regional Autonomous Systems stitched together.
That means that once data gets on the network, it’s
a single BGP hop to the global network node nearest
its destination. This minimizes the number of router
hops and reduces the risk of downtime when traffic has
to traverse multiple networks.
Some of our international competitors support services
on multiple continents through joint ventures and partnerships.
SAVVIS owns its own network - there are no joint ventures
that may affect performance and support.
A single AS means:
• Customers are only one hop away from content hosted
on the SAVVIS network.
• Access to all of
the routes on the Internet.
• A single end-to-end
Service Level Agreement.
Network features include:
• Based on industry-leading
Juniper core routers and Cisco equipment specifically
designed for the needs of Tier 1 "carrier-class"
customers.
• OC-48/OC-192
backbone trunks, supporting MPLS protocol.
• AS3561
is consistently rated over time as having the lowest
latency, lowest packet loss, and highest reliability.
• SAVVIS firmly segregates Layer-2 (transmission) and
Layer-3 (routing):
• Layer-2 is ATM-based for traffic management.
• Core network is designed for “zero” packet loss.
• SAVVIS is moving
to more efficient MPLS Layer 2 protocol

SAVVIS primarily peers in Chicago, Seattle, Washington
DC, Atlanta, Dallas, New York City, and San Francisco.
Peering
The SAVVIS Global AS3561 IP backbone has peering connections
with 13 Tier 1 US and five Tier 1 European backbone
providers. SAVVIS has built new OC-3 [STM-1] and OC-12
[STM-4] for a total of 26GBps connections to its largest
direct connect peers, thus providing faster and more
reliable access to their networks. With these enhancements,
SAVVIS is able to allocate sufficient bandwidth to each
peer, aiding in effective capacity planning.
In Europe, SAVVIS maintains pan-European
private peering connections at LINX, PARIX and AMSIX
operating at STM1 or higher speed with GTS/Ebone, Infonet/AUCS,
UUNET AS703, Teleglobe and KPNQwest/EUNET. Additional
European peering connections are under consideration.
These connections will provide
our US customers with direct access close to 100 percent
of the global address space and our European customers
with direct access to 90 percent of the European address
space. The benefits to SAVVIS customers include: faster
access, minimum AS hops, lowest possible packet loss,
and a better ability to plan for future growth for ISPs
that peer with the SAVVIS IP backbone.
With an aggressive peering plan,
including peering agreements with the largest Tier 1
backbones, SAVVIS is one of the leaders in the industry
in finding efficient ways to route IP traffic through
our network and beyond.
With the globalization of the
Internet and SAVVIS' response of expanding the US based
IP backbone to a truly global backbone under one AS3561,
peering has become increasingly complex and the established
peering policies have been amended. SAVVIS has formulated
a global peering policy to maximize the benefits of
peering to our customers and also provide equitable
treatment of our peering partners.
In addition to its peering relationships,
SAVVIS has direct transit connections with over 1,300
ISPs in the US and 100 direct connections to ISP's in
over 70 countries. In peering and transit arrangements,
SAVVIS' global AS3561 stands for quality, unsurpassed
in the industry.
SAVVIS is a Tier 1 ISP that offers
both IP connectivity and e-business solutions to enable
global corporations to quickly reach their desired Internet
content. To offer our customers efficient access to
destinations that reside outside of SAVVIS’ Global IP
Network, peering has been established at select major
cities where our backbone nodes are present. In the
USA, we have established peering relationships with
the four other Tier 1 ISPs: AT&T (ANS), Genuity
(GTE Interlink), UUNET (WorldCom), and Sprintlink.
As is the case with all Tier
1 ISPs, SAVVIS is prohibited from peering directly with
any network outside the USA; however, our 270 transit
relationships with 80 countries will provide the customer
with excellent connectivity to overseas markets. We
peer with five pan-European Regional Tier 1 networks
including: UUNet (WorldCom), Ebone (GTS), AUCS (AT&T
and Infonet), EUNET (KPN/Qwest), and France Telecom
(which includes Global One and Equant), providing SAVVIS
customers access to 90 percent of all European routes.
In Asia, SAVVIS is establishing similar peering connections
in Japan to provide similar route coverage. Once these
peering arrangements are in place, no other Tier 1 ISP
will be able to match SAVVIS’ global peering coverage.
