               (a)    adding Participant to a unique collocated network
                      interconnect in vivo testbed in which Participants
                      exchange data among their client networks as well as with
                      NASA networks and other cooperating commercial and Federal
                      networks that are similarly attached at this testbed which
                      is known as MAE-West (Metropolitan Area Exchange - West
                      Coast) which is part of the ▇▇▇▇ Internet Exchange;
               (b)    facilitating (1) the metering and analysis of internet
                      traffic flows, (2) the study of new algorithms for caching
                      internetwork flows, and (3) the development of new
                      approaches to traffic moderation by aggregating
                      Participants on a common testbed to share in the resulting
                      costs and benefits;
               (c)    providing new technology transmission facilities, either
                      terrestrial or satellite, that stimulate competition and
                      cost moderation as new network capabilities are introduced
                      by Participants; use of such new technology is essential
                      to efficient operation of NASA and other Federal networks;
        The foregoing statements of purpose (a) to (c) support NASA-▇▇▇▇
Research Centers role as NASA lead center for Information Systems Technology.
        This interconnect testbed shall be located at NASA ▇▇▇▇ Research Center
