Internet Technology and Protocols

Knowing the architecture of numerical transport networks for telephony and data and their evolution. Gaining an understanding of the transport problems of IP on the network backbones and MPLS technology. Understanding the architectures and protocols for the transport of the Voice over IP, from the point of view of signaling and the audio streams transport. Knowing the alternatives for access networks. Acquire a good knowledge of the technologies Ethernet switched for wired LANs, IEEE 802.11 for Wireless LAN and of network architecture for xDSL access.
