In recent years, Path Computation Element (PCE) architecture has been standardized as a suitable solution for path computation in multi-domain network scenarios. The Traffic Engineering Database (TED) of the PCE is updated with the information of the control plane. However, there is a delay from the PCE replies to a ...Download Now
The implementation of Network Centric Services (NCS) is interesting for network operators, because it enables creating new business opportunities. A NCS combines IT and network resources. Examples of NCS are: Virtual PC, Video on Demand (VoD), SaaS or gaming. These services combined with Internet traffic growth impact the network cost ...Download Now
The recent attention that Path Computation Element (PCE) architectures have received is mainly because of its potential to provide feasible solutions for multi-layer networks and to solve the interconnection of services into multiple domains. In particular, complex routing problems emerge when light-paths cross multiple domains combined with multi-layer traffic engineering. ...Download Now
