The invention comprises a system and method for monitoring the performance of an application. This is realized by spatial, temporal or spatio-temporal filters. Opposing panels are placed end to end in rows and stacked vertically, rows of panels being staggered from each other so panel ends in adjacent rows do not line up vertically. The method comprises configuring switches in the plurality of collocation sites to partition rings in the plurality of rings into a plurality of link segments providing point to point paths between switches at collocation sites in the plurality of collocation sites.
