In the management of spatial mobility assessment requires the organization of systematic monitoring, which includes identifying the mobility potential in spatial and temporal interpretation, th...

This paper describes methods to reduce channel contention during distributed setup of high-speed connections in a mesh network of Cross-Connects (XCs) [1]. A particular aspect of contention addressed here is when two different connection requests arrive on a pair of adjacent XCs and they choose the same restoration channels from spare inventory. Such a contention problem is often referred to as...
