About Savvis | Print |

SAVVIS has engineered its Internet network around a single platform - AS3561 - which enables one global IP backbone, rather than regional Autonomous Systems (AS) stitched together.  That means 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:

  • Customer users 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
  • 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.
  • Migration path to MPLS as combine Layer-2/Layer-3 protocol
  • Core network is designed for “zero” packet loss.

SAVVIS implements route-policies with all of its' customers wishing to utilize BGP4 routing in lieu of static routing. In order to allow customers the flexibility to update their routing-policy dynamically, SAVVIS utilizes a routing-registry (a database of routing information) known as the SAVVIS-RR. The SAVVIS-RR is a commercial routing-registry and is maintained for the use of SAVVIS's customers.


If a customer is already registered at another routing-registry, the customer may continue to use that routing-registry and update as needed. When requesting BGP4 routing, be sure to advise SAVVIS at that time as to the alternate routing-registry used, so the route-policy may be set up accordingly. SAVVIS mirrors the data stored on many routing-registries currently used throughout the Internet (to ensure SAVVIS mirrors the registry in question, please email savvis-rr@savvis.net.

The SAVVIS Global AS3561 IP backbone has peering connections with twelve Tier 1 US and twelve Tier 1 European backbone providers. SAVVIS exchanges traffic with some of these peers on both sides of the Atlantic.   This makes a total of 20 peers.  SAVVIS has built new optical links for a total of 125GBps of aggregate bandwidth to its peers, thus providing faster and more reliable access to all 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, DECIX, and AMSIX operating at STM1 or higher speed.  SAVVIS AS3561 is a transit-free network.  These provide direct connections to peer networks of a size and scope similar to SAVVIS, i.e. the largest backbones in the Internet.  This enables SAVVIS to announce a full routing table, with direct connections to all top level networks.  These connections provide our customers with direct access to 100 percent of the global Internet address space.  The benefits to SAVVIS customers include: faster access, minimum AS hops, lowest possible packet loss and latency and a better ability to plan for future growth for ISPs that are connected with the SAVVIS IP backbone.


With these established Tier 1 peering arrangements, SAVVIS is one of the leaders in the industry in finding efficient ways to route IP traffic through our network and beyond.

Driving part of the globalization of the Internet, SAVVIS has extended its’ 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 provides direct transit connections to about 1,000 ISPs in the US and over 100 direct connections to ISPs in over 50 countries.  In both 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 companies across all markets 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 meet our peers at major exchange points around the country, namely: Chicago, Seattle, Ashburn, Washington DC, Atlanta, Dallas, New York City, Palo Alto, Los Angeles, San Jose, and San Francisco.   In Europe AS3561 meets its’ peers in London, Paris, Frankfurt, and Amsterdam.

SAVVIS peers with twelve pan-European Regional Tier 1 networks providing SAVVIS customers direct access to most European routes. In Asia, SAVVIS has subsidiary and customer networks that provide excellent connectivity into the region. 


Due to certain clauses contained in the Peering Agreements, which protect the disclosure of the peering details, SAVVIS and its’ peers are prohibited from disclosing specifics of our Tier 1 peering arrangements.  However, the performance of our network and the rich connectivity it provides are a testimony to the quality and user experience that SAVVIS delivers.
