Three key needs are identified; rapid introduction of new services, dynamic customisation of services by clients, and minimal management overhead. Application layer active networking, perhaps the most pragmatic and immediately realisable active network proposal, is a potential solution to all three. Combining eXtensible Markup Language and Application Layer Active Networking yields strong benefits for networked services. A Wide range of applications can be developed based on the flexibility of XML and the richness of expression afforded by the metadata. A system of network intermediaries based on caches, which are also active and driven by XML metadata statements, is described.

It is composed by ROADM remotely controlled by a GMPLS- based control plane. The paper highlights some open issues in the deployment of services-aware intelligent optical networks.

In this scenario dynamic routing based on traffic engineering techniques is a key issue. This paper deals with dynamic routing in ASON/GMPLS networks based on using network failures information. We define three routing strategies which differ in the use of failure information. Their performance is evaluated by simulation in terms of request blocking probability and availability
