This paper reviews the work carried out under European ACTS KEOPS (KEys to Optical Packet Switching) project, centering on definition, development and assessment of optical packet switching routing networks capable providing transparency payload bit rate. The adopted approach uses packets fixed duration with low rate headers facilitate processing at network/node interfaces. concentrates networking concepts developed in project through a description implementation issues pertinent nodes...
Web-based applications rely on the HTTPS protocol to guarantee privacy and security in transactions ranging from home banking, e-commerce, e-procurement those that deal with sensitive data such as career identity information. Users trust this prevent unauthorized viewing of their personal, financial, confidential information over Web.
In this letter we consider burst switching for very high speed routing in the next generation Internet backbone. scenario, protocol (IP) packets to a given destination are collected bursts at network edges. We propose assembly mechanism that can reduce traffic autocorrelation or degree of self-similarity, and same time keep delay due formation limited

As it is happening in many fields that need efficient and effective classification of data, Machine Learning (ML) becoming increasingly popular network management monitoring. In general we can say ML algorithms are complex, therefore better suited for execution the centralized control plane modern networks, but also heavily reliant on necessarily collected data plane. The inevitable consequence may arise to transfer lots from plane, with risk cause congestion communication channel. This turn...
