A devised Global Concurrent RSA algorithm to maximize connection restorability is experimentally evaluated.

However, to the date, not much use of this service has been made by operators. This work addresses the reasons behind this fact, identifies the key technical design factors in a multicast-capable network and the challenges to face for an effective use of multicast at the optical layer.

In many ways, IPv6 technology has addressed several problems that can pave the way for this technology. This paper analyses IPv6 from the active networking viewpoint and introduces an active network architecture developed in the context of the IST project GCAP. During the last years most of internet actors' interest has focused on service cre a- tion and content production, and this trend has grown at the pace of the business d e- velopment of the internet. Being the first one to put a new service into the internet market represents an advantage over competitors whose magnitude is deemed to be much higher than the one obtained in conventional markets. In some cases, new se r- vices mean new protocols ...

This small-cell approach faces a number of technological challenges when it comes to the design of an appropriate backhaul network. However, not less importantly, it also poses a financial challenge for operators, given the high cost of deployment and maintenance of a large amount of active devices connected at gigabit speeds scattered over a metropolitan area.
