There exists a waste of bandwidth resources due to the heuristic algorithms for the preemption in multi-protocol label-switching (MPLS) networks.
目前多协议标签交换(MPLS)网络中大多采用启发式算法进行抢占，造成了带宽资源的浪费。

We put forward a new method to realize optical label switches using the phase shifted effective in Bragg phase shifted grating and device a experiment to achieve optical labelswitching.
Generalized multi-protocol labelswitching (GMPLS) supports peer model networks. GMPLS technology and routing mechanism are the key technologies for constructing peer model based optical Internet.
