Network Overview
......................................................
To deliver on our 99.9% Service Level Agreement, Hitdriven
Hosting partnered with the best of the best in data center operations - Savvis
(DFW1 - located in Dallas, Texas)
Our networks architecture utilizes the Enterprise routing and switching engines from Juniper and Cisco.
SAVVIS DFW1 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.
Customers are only one hop away from content hosted on the SAVVIS network.
Network Highlights
- 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
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 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 with the SAVVIS IP backbone.
