摘要

In a software defined network, the controller needs to obtain/collect traffic measurement information (i.e., flow statistics) from switches for different applications, such as traffic engineering. Existing solutions seldom consider the per-switch cost, which may lead to heavy statistics collection cost (e.g., high CPU overhead) on some switches. Due to limited com...
