 battery, and nonvolatile memory. It independently establishes the Internet Protocol security (IPsec) tunnel that secures the remote access connection, and its WWAN interface makes the laptop reachable by the IT organization virtually anytime and anywhere. The Evros gateway is an enhanced secured access server that is deployed within the network perimeter. It hosts the enterprise end points of the IPsec tunnels and exploits the extended reachability of the laptop to improve the effectiveness of all Overview of Cognitive NGSDP Model remote management functions. The Evros management server is a software suite for the management of all Evros components [70]. 6.5 Summary IMS combined with SDP will lead to a new future for telecom operators and multi- media markets, while the actual constructions of NGSDP should take into consid- eration APIS-Applications, Performance, Intelligence, and Security. Cognitive NGSDP focuses more on performance and intelligence aspects, combining cognitive functions with NGSDP requirements. Principles of cognitive domain management and theories of cognitive science, machine learning, and decision making are utilized to contribute to the implementation of cognitive processes. Security problems, from business processes, telecom networks, and software engineering should all be consid- ered to guarantee correct services execution, system security, and attacks prevention. With this overview of Cognitive NGSDP, we hope it can help understanding and actual progresses of SDP. And we believe SDP development and progress will lead to a new considerable future for both telecom industries and global customers.
