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, it9s 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 9zero9 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 SAVVIS9 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 SAVVIS9 global
peering coverage.
The DataBank network: AS13767
Our network architecture utilizes Foundry and Cisco carrier
class routing and switching equipment to provide a Highly
Redundant and Highly Available Multi-Homed Internet Aggregation
Hub. We utilize Foundry RX16 and Cisco 6500 series switches
and routers in our network to provide up to 3.84 Tbps of
switching and routing capacity. This coupled with multiple
Gigabit trunks from multiple Internet service providers makes
DataBank9s IP Hub one of the most robust in the industry.
Network features include:
- 3.84 Tbps of switching and routing capacity designed
for the needs of Enterprise and carrier-class customers
- Multiple Gigabit Ethernet backbone trunks
- Core network is designed for 9zero9 packet
loss
- Embedded sFlow per port supports scalable hardware-based
traffic monitoring across all switch ports without impacting
performance
