Information
To
meet the demanding needs of your business and to help hone your
competitive edge, a world-class IP provider must demonstrate key
criteria: a robust infrastructure, advanced technology, extraordinary
capacity and reach, dependable and multi-tiered security, support
for a rich array of applications and services, guaranteed service
levels, a global presence and the ability to supply services not
just to its own customer base but to other providers.
The
highly reliable AT&T IP Backbone allows AT&T to take a position
as a Tier 1, world-class provider of IP services, meeting all
of the criteria listed above. Some of the many features of the
AT&T IP infrastructure – all owned and controlled by AT&T – include:
-
Multiple,
high-speed OC-48 (2.5 Gbps) and OC-192 (10 Gbps) interoffice
trunk facilities; AT&T was the first ISP with a fully operational,
coast-to-coast OC-192 IP Backbone; AT&T was first ISP to establish
a cross-country OC-48 link and the first to carry live customer
traffic via an OC-192 link
- A
highly reliable core network, consisting of more than 53,000 miles
of fiber optic cable and more than 80 self-healing SONET rings
– more than any other carrier in the industry
- An
additional 16,500 miles of next-generation (OC-192 and OC-768-capable)
fiber currently being deployed
- Default-free
routing, in which packets flow directly from the AT&T IP Backbone
to other ISP networks via peering or customer connections – the
most direct route possible
- PeerMon,
a real-time monitoring tool that detects possible changes or modifications
to the routes of AT&T’s routes as advertised by peers in order
to enhance routing stability
- Consistently
low latency, supported by Service Level Agreements (SLAs) of 60
milliseconds for a network-wide average roundtrip between city
pairs in the US and 120 milliseconds for the average round-trip
delay of the fastest link between New York and London and between
Washington, DC and Amsterdam
- Low
packet loss, with a network-wide average of no more than 0.7%
- Multi-layered
security architecture and physical security for all backbone nodes
- Support
for Virtual Private Networks, intranets and extranets, Web hosting,
IP-enabled fax, IP-EDI, managed security services and much more
- Multiple
access choices, including dial, private line, ATM, frame relay,
cable modem and DSL (Digital Subscriber Line)
- Global
reach through points-of-presence in 850 cities in more than 50
countries
