Sprint Network
Information
In
1992, Sprint became the first interexchange carrier (IXC) to offer a commercial
Internet service. As an Internet pioneer, Sprint has continued to prove itself
as a leader in IP technology and networking time and again, from being the first
carrier to implement a GigaPOP backbone architecture in 1997, to deploying the
first trans-Atlantic OC192 in 2001.
Sprint has often been called a "technology and engineering company," and herein
lies the key to Sprint's success in IP networking. The SprintLinkTM backbone was
built from the ground up as a 100% native IP platform with reliability as the
number 1 priority. The SprintLink backbone is engineered so that all network
links do not exceed 50% utilization. Links between backbone nodes are configured
using multiple logical adjacencies via diverse physical paths. Simply put,
multiple links are provisioned in pairs. For example: 2 physically diverse
circuits, Circuit A and Circuit B, would be provisioned between cities and both
Circuit A and Circuit B are active. If Circuit A were to be cut, all impacted
traffic would instantly be diverted to Circuit B (see sidebar, Technology
Highlight).
In
addition, Sprint engineers have developed a patented 4-fiber, bi-directional
line-switching SONET ring which functions as a U.S. domestic access network for
Sprint Internet customers. This unique access architecture provides millisecond
restoration that, in the event of an outage or fiber cut, seamlessly re-routes
customers' traffic to avoid traffic interruption. It is this robust and
"redundantly, redundant" network architecture that allows Sprint to provide
unsurpassed survivability.
Today, the Sprint Internet backbone extends to more than 400 points of presence
in the United States, Europe, and Asia carrying roughly one-quarter of the
world's Internet traffic. Building on a history of technology innovation, Sprint
continues to explore advancements in IP networking so Sprint's backbone
maintains one of the highest levels of efficiency possible. With performance
metrics backed by a state-of-the-art Network Operations Center and
industry-leading Service Level Agreements, you can be confident that your
business information will be delivered quickly and reliably.

History
As
an Internet pioneer, Sprint has the knowledge and the experience to deliver
industry innovations that can improve your business performance. Here's a
timeline of Sprint's key accomplishments.
1992
Sprint was the first interexchange carrier (IXC) to provide a
commercial Internet service using a T1 network
1993
Sprint was first to deploy an all DS3 native IP network, and a DEC
FDDI Gigaswitch PoP Architecture
1995
Sprint launched the world's fastest transoceanic Internet link —
capable of carrying Internet traffic at 155 Mbps, 17 times faster than
before. This was the world's first international broadband Internet
service
Sprint began working with Cisco to build the next router required for
making the Internet scalable OC3 US network using Cisco 7500 routers
1996
Sprint was the first IXC to offer a commercial intranet service using
a dedicated, native IP backbone. This means you can open up your
intranets to more locations economically and maintain a high-level of
performance
Begin deployment of OC-12 four fiber bi-directional SONET rings
Beta testing of Cisco Gigaswitch router (GSR) began in early 1996 with
production deployment in late 1996
1997
Sprint was the first ISP to deploy a GigaPOP backbone — using Cisco
gigabit switching routers connected by all OC-12 Packet-Over-SONET
(PoS) wide area network links — the world's first OC-12-based network
dedicated exclusively to Internet traffic using Cisco 12012 GSR
routers. This advanced network design allowed Sprint to deliver the
performance and reliability demanded by your business
1998
Sprint launched Web Hosting services with 100% site availability SLA
with dual Internet Data Centers or 99.5% with single site internet
Data Center
First provider to deploy OC48 IP network links utilizing
Packet-Over-SONET (PoS) over Dense Wave Division Multiplexing (DWDM)
1999
Sprint took the Editor's Choice award for WAN Access by Network
Computing. 1999 also saw the launch of Sprint Internet VPN, Sprint
eCommerce Storefront, and EDI Services
Sprint became the first Internet provider to offer native
multicasting. Sprint was the first to roll out nationwide OC48 DWDM
all IP network
First to deploy Cisco 12016 routers in production network
2000
Sprint launches Sprint E|Solutions to provide E-business and managed
services. Sprint also offers suite of E-business solutions for
E-commerce, intranet, extranet, and Internet solutions
Sprint announces industry-leading Internet SLAs
Sprint receives Network Computing's Well-Connected Electronic Commerce
Award and E-Commerce Host Service Provider
Sprint is the first carrier to be awarded Cisco Gold Certification
status for Managed Network Services
2001
Sprint sets new standard with industry-leading packet loss SLA, and
has undergone an aggressive Internet Data Center expansion
Sprint was the first to provide OC-192 transatlantic capability.
Industry's first transoceanic OC192/STM-64 deployed in Europe and Asia
Sprint migrated all backbone routers to Cisco 12416 GSR routers
