SAN FRANCISCO--(BUSINESS WIRE)--April 5, 2000

Yipes Communications Inc., the leading optical IP network provider, announced today that it has selected the Service Management Architecture (SMA) from Jyra (OTCBB:JYRA) as part of its premier network service management portfolio. Jyra software agents will be placed at every point of presence (POP) on Yipes' next-generation network to monitor end-to-end network and application response time for its customers.

[pilcrow (paragraph sign)] Yipes provides business customers with light-speed data services featuring unmatched flexibility and scalability using the familiar and pervasive Ethernet interface. Customers may select LAN-to-LAN service between business locations or high-speed Internet access, both scalable from 1 Mbps to 1 Gbps, in 1 Mbps increments. With true bandwidth-on-demand, Yipes customers pay only for what they need.

Yipes is also setting a new standard for customer service. Yipes' services are backed by aggressive Service Level Agreements, which assure business quality of service, low latency and guaranteed bandwidth availability.

Jyra agents will measure hop-by-hop latency throughout the Yipes state-of-the-art optical IP network and alert Yipes' Network Operations Center (NOC) should the response time exceed pre-agreed service levels. Jyra SMA's distributed architecture can capture the end-to-end response time data from local, regional and national perspectives.

"The remarkable ability of Jyra's Service Management Architecture to scale with Yipes' rapidly-expanding IP networks was instrumental in our decision to purchase it," said Dr. Kamran Sistanizadeh, Vice President of Network Architecture at Yipes. "Jyra is providing us with a critical tool to offer highly flexible and reliable managed services to our customers now and in the future."

Jyra has successfully marketed the SMA to Service Providers throughout Europe in the past two years. Yipes is the first large U.S. service provider to deploy Jyra's SMA. "Yipes' decision to select our SMA in their portfolio for SLA monitoring is a strong endorsement of Jyra's cutting-edge technology in the U.S. market," said Erfan Ibrahim, VP of North American Sales at Jyra Research Inc.

"Yipes' optical fiber access at up to a gigabit per second really opens up the bottleneck that so far has held back new services that need truly broad bandwidth," said Bill Flanagan, Program Director at The Burton Group. "But business customers need reliable, assured services as well as raw bandwidth, and Jyra's solution will help Yipes deliver true business quality of service."

Yipes network services are available today in Boston and suburban San Francisco, Los Angeles and Denver. Yipes plans to have a nationwide footprint by the end of this year, with services available in major cities coast to coast.

Yipes is the defining provider of a new class of managed optical IP networks. Yipes leverages the elegance of native Ethernet technology to provide service that is smoothly scalable (in 1 Mbps increments) from 1 Mbps to 1 Gbps, enabling the next generation of Internet services. Yipes' networks provide roughly twice the bandwidth at 80 percent of the price of traditional data communications services. Yipes' is funded by Norwest Venture Partners, New Enterprise Associates (NEA), The Sprout Group/DLJ, Soros Private Equity Partners, Chase Capital Partners/Hambrecht & Quist, BancBoston Ventures/Robertson Stephens, NewSpeed Capital and strategic investors Juniper Networks, Inc., Extreme Networks and Intel Capital.
