A simple insight about availability guarantee with time variation in survivable WDM mesh networks

Availability is an important metric in mesh works. Many previous works have discussed differentiated services provision with availability guarantee. Nowadays, a new request that will use the special wavelengths to transmit different availability traffic appears. In the duration of its holding time, customers will have different availability requirements. Based on this, we propose a simple scheme called time aware availability guarantee (TAAG) to discuss availability guarantee with time variation. Compared to time unaware availability guarantee (TUAG) scheme, TAAG performs better in resource utilization, blocking probability and traffic throughput.
