Odposlech a záznam telekomunikačního provozu / Wiretapping and recording of telecommunication trafficFrolková, Klára January 2016 (has links)
This thesis is devised as an analysis of the legal framework of the institutes of wiretapping and recording of telecommunication traffic, as well as the survey of the telecommunication traffic, which is included in the § 88 and § 88a of the act no. 141/1961 Coll., Criminal Procedure, as amended. The aim of this thesis was to analyze in detail the current and valid legal framework with respect to the protection of human rights and to point out the fact that the use of these institutes often finds itself on the threshold of considering the interference with the personal sphere of an individual to be justified/justifiable as well as the slight overstepping of such threshold by the public authorities, which I assume. The thesis is divided into four connecting chapters, not including the introduction and the conclusion. In the first chapter, which is divided into two sub-chapters, I address primarily the legal evolution of the examined institutes, as to when was the first time these institutes were incorporated into the valid legal framework and brought to life, their subsequent development and the most important amendments throughout the years. The second sub-chapter outlines the technical development from the not so distant past to the present, where I think about the evolution of technical...

Modeling and adaptive resource management in integrated communication networks.Meempat, Gopalakrishnan. January 1989 (has links)
The focus of this dissertation is the development of resource management schemes for integrated networks, with the major contributions being: (i) the development of an optimal adaptive buffer management scheme for the packet-switched subsystem, (ii) the integration of a moveable-boundary hybrid switching scheme with the time assigned speech interpolation technique for implementing a congestion control mechanism for the packet-switched subsystem, and (iii) the development of an adaptive hierarchical scheme for implementing the access control and routing functions within the circuit-switched subsystem. The problem of buffer management at an integrated network node is formulated as a nonlinear programming problem with a convex objective function and an interative solution technique with fast convergence is proposed for a real-time implementation of the buffer management scheme in practical environments. In order to exercise an additional degree of control over the packet-blocking probability at each hybrid-switched link within the network, a new multiplexing scheme based on the integration of the moveable-boundary hybrid switching scheme and the time assigned speech interpolation technique is presented in this dissertation. The tradeoff between the corresponding decrease in the packet blocking probability and the increase in the circuit freezeout fraction is demonstrated by a detailed queueing analysis of the multiplexer. Specific algorithms are also presented in this dissertation for the solution of the access control and routing problems within the circuit-switched subsystem. In particular, an access control scheme is developed by solving an integer programming problem formulated using the policy of complete partitioning of the available bandwidth among the competing user classes. As an alternative to the completely partitioned approach, the problem of traffic routing is considered in a network that supports homogeneous traffic classes based on the policy of complete sharing. Finally, for the general case of networks with heterogeneous traffic classes, a hierarchical scheme is developed for the implementation of the access control and the routing functions at two functional levels, where the access control is implemented by the network supervisor who solves an appropriate linear integer programming problem periodically, and the routing function is handled by the individual nodes of the network on a distributed basis.
