本文描述了光-GMPLS-路由器（Hikari-router）网络中的多层流量工程和信令技术。多层流量工程，它产生的IP和光子层的动态合作，描述了以提供IP服务的成本效益的目标。当第3层业务负载变得过多时，触发光子直通路径的建立，这更好地使用了光层（LI）资源。使用扩展IBGP在边缘光子路由器之间交换有关流量的数据。为了实现多层流量工程，我们提出了一个OSPF的扩展，这两个数目的总波长和未预留的波长，和RSVP-TE扩展，最大限度地减少所需的波长转换的数量。此外，本文提出了一种基于拓扑的多层拓扑设计方案，其中IP流量测量在广义多协议标签交换（GMPLS）中进行。我们的设计方案产生了光标签交换路径（OLSP）网络拓扑，即OLSP放置，可以在IP流量需求波动的情况下最大限度地降低网络成本。换句话说，OLSP网络拓扑被动态地重新配置以匹配IP业务需求。通过该方案对网络进行重新配置，从而有效地利用网络资源。
This paper describes multilayer traffic engineering and signaling technologies in the photonic-GMPLS-router (Hikari-router) network. Multilayer traffic engineering, which yields the dynamic cooperation of IP and photonic layers, is described with the goal of providing IP services cost-effectively. The establishment of photonic cut-through paths is triggered when the Layer 3 traffic loads become excessive which better uses the optical layer (LI) resources. Data on traffic volumes are exchanged among edge photonic router using an extended IBGP. To realize multilayer traffic engineering, we propose an OSPF extension that advertises both the number of total wavelengths and the number of unreserved wavelengths, and an RSVP-TE extension that minimizes the number of wavelength conversions needed. In addition, this paper presents a heuristic-based multilayer topology design scheme in which IP traffic measurements are performed in generalized multiprotocol label switches (GMPLSs). Our design scheme yields the optical label switch path (OLSP) network topology, i.e. OLSP placement that minimizes network cost in the face of fluctuations in IP traffic demand. In other words, the OLSP network topology is dynamically reconfigured to match IP traffic demand. Networks are reconfigured by the proposed scheme so as to utilize the network resources cost-effectively.
