LEADING INTERNET VENDORS TEST INTERNET2 QUALITY OF SERVICE TECHNOLOGY
First Qcon Event Tests Emerging IETF Internet QoS Standard
Research Triangle Park, North Carolina--November 12, 1999--Network engineers
from Internet2 corporate members gathered last week for the first Qcon
Interop event to test Internet Protocol (IP) Quality of Service technology.
Advanced network applications such as better-than-TV quality video and
real-time collaboration require Quality of Service (QoS) technology being
developed by the Internet2(tm) QBone initiative to provide the guaranteed
network performance not possible with today's Internet technology.
"This event provided experience and information on the status of commercial
implementations differentiated service that will further serve as a
significant proof of concept test of expedited-forwarding based premium
service that we are developing and deploying as part of the Internet2 QBone
initiative," said Ben Teitelbaum, chair of the Internet2 Quality of Service
Working Group.
Cisco Systems, Nortel Networks, Hitachi and Cabletron Systems provided
equipment which was tested with support from Netcom Systems. Tests provided
quantitative measures to validate implementations of the differentiated
services (DiffServ) components of standards currently under consideration by
the Internet Engineering Task Force. These standards aim to provide QoS for
IP networks. Extensive results from the Qcon event, which will be published
next month, will provide valuable information on the state and quality of IP
QoS implementations in commercial routers.
Qcon, held at the North Carolina Super Computer Center, was sponsored by the
Internet2 QBone initiative, Netcom Systems, the North Carolina Network
Initiative (NCNI) and North Carolina State University. As the first of a
planned series of events, last week marked initial progress towards
developing an automated suite which will allow the Internet2 community to
test DiffServ implementations.
