The California Institute of Technology (Caltech) is a highly focused science and engineering research and education institution located in Pasadena, CA. Their challenges are to prepare for startup of major physics experiments, CMS and ATLAS, at the Large Hadron Collider, overcome limitations of long-range networks and storage to share massive amounts of data among global research collaborations. They chose Cisco to overcome these challenges. They have implemented high-speed intelligent switched IP network with 10 Gigabit Ethernet line cards and MPLS, VLANs and policy-based routing features help segment, prioritize and direct traffic flows across the global computing grid. The results of implementing Cisco were upgraded to higher density switches without changing switching chassis and achieved high performance in a production network to share process.
