The future Internet would benefit from the delivery of high performance services crossing several carriers and bringing new incomes to telco operators. Such services compel carriers to guarantee quality of service (QoS) inside their boundaries. As carriers are independently administrated, architectures and processes must be reconsidered so that requirements for autonomy and confidentiality are respected...
Providing inter-domain QoS guaranteed services is a huge challenge for operators and will bring new revenues to them. But, establishing end-to-end services requires a level of resource management that does not exist yet, even locally to an operator. Due to confidentiality and independence reasons, operators are afraid to cooperate which can not be avoided in the inter-domain context. We consider the...
This paper presents a testbed implementation of an inter-carrier GMPLS (generalized multi protocol label switching) service architecture recently proposed. This architecture couples the path computation element (PCE)-based control plane with a service plane managing discovery, composition and activation functions of inter-carrier service elements. The testbed implements the required PCE communication...
