SAVVIS Selects Sonoma Systems' for Its Business-Class Internet Access Service.

MARINA DEL REY, Calif.--(BUSINESS WIRE)--Oct. 4, 1999--

Sonoma Systems, a leading provider of integrated access devices, today announced that the Sonoma Access has been selected by SAVVIS Communications, a leading global internetworking solutions provider, to help deliver high speed, Ethernet-based Internet services to its corporate customers.

"The Sonoma Access integrated access device allows SAVVIS to maintain its end-to-end SLA guarantees to its customers. These SLAs, which are considered the most aggressive in the industry, demand the support of superior products. The Sonoma Access device has proven itself as a reliable, quality solution for our Ethernet Internet services. These Internet services, added to our successful managed data networking products, create a total solution for our customers," said Rick Bubenik, CTO and Executive Vice President of Networking Engineering for SAVVIS.

SAVVIS required a business-class Internet access solution that would efficiently interface to their customer's complex, constantly changing networks. In response to this need, Sonoma developed Port-Based Default Routes (PBDR). With PBDR, the need to frequently reconfigure the access device in response to network changes is eliminated, minimizing maintenance and operations cost. PBDR speeds provisioning, simplifies network maintenance and reduces service deployment costs for SAVVIS' line of Internet access services.

According to Bubenik, "Sonoma's innovative PBDR solution has enabled us to dramatically reduce provisioning and maintenance time. This was an important feature given our focus on customer satisfaction."

SAVVIS' Global Internet service using Sonoma Access is immediately available.
