This article presents a review of the investigation of the possibility of increasing the efficiency of existing line test solutions for troubleshooting testing for IPTV over xDSL, by the results of experimental research on real system under commercial exploitation. At the beginning of this article the main weaknesses of the existing troubleshooting testing are described. In the continuation of the article the physical layer parameters of xDSL transceiver are listed. In the reset this article provides a few specific examples of xDSL lines with their physical layer parameters of xDSL transceivers followed by analysis how they can be used for the purposes of more efficient measurement of parameters of copper pairs.
This paper proposes metrics based on QoS preferences of MNs, and QoS abilities of MAPs, in order to perform a simulative evaluation of the Hierarchical Mobile IPv6 (HMIPv6) network implementation with QoS-aware dynamic MAP selection. The chosen metric meets the desired level of QoS, while retaining MAP load balance, while the DiffServ mechanism ensured the required QoS for HMIPv6 network implementation with QoS-aware dynamic MAP selection.
