An obgp-based inter-domain lightpath setup mechanism with diffserv support 的支持区分服务的域间光路建立机制
The phase difference in the two arms of a mzi is vital for a mzi-based sensor, and the phase ( of each lightpath ) should be determined with an accurate modal analysis mzi两臂光路问的相位差对于mzi传感器至关重要,因此它们各自的相位值必须通过精确的模式分析来确定。
By using this algorithm, the difference in blocking rates among lightpath connection requests for different distances is reduced by updating the initial priority levels and fairness in the wavelength assignment improved 该算法在支持多优先级的动态门限法的基础上,通过更新初始优先级减少了不同距离光路连接请求间的阻塞率差别,改善了公平性。
Simulation results show that the developed scheme performs well in terms of qos performance metrics such as the lightpath hop length and the network maximal link load . for ip over wdm networks consist of oxcs and routers, which are inter-connected by optical fibers, chapter 3 presents a novel routing and wavelength assignment algorithm based on k-shortest path 对于由大量路由器和oxc通过光纤互连而组成的ipoverwdm网络,第三章创新性地提出了将ip层矛咣层综合考虑进行:路由选择,并利用k??最短路由对有长度限制的请求进行资源分配的算法。
A key issue in networks design is to optimize routing and wavelength assignment ( rwa ) for lightpaths . rwa solves how to find out an appropriate lightpath and assign a wavelength reasonably in order to make full use of the limited resource and provide communication capability as large as possible 优化光通道的选路和波长分配(rwa)是网络设计的核心问题,其主要任务是寻找一条合适的光路并为之合理地分配波长,使有限的资源充分发挥作用,以提供尽可能大的通信容量。
