摘要：
We analyze the cost of IP- over- WDM networks employing survivable traffic grooming protection. The network cost is evaluated in terms of total number of optical transceivers in the network, total amount of electronic switching, and maximum number of optical transceivers at a node. The network cost is compared with the cost of networks employing other protection strategies, namely, IP protection and WDM shared protection. The minimum cost problem is mathematically formulated for the three protection approaches. Our results show quantitatively that the evaluated survivable traffic grooming protection scheme is the most effective. (C) 2007 Optical Society of America.
