Under this initiative, ITU plans to establish training centres to provideskills in Internet Protocol (IP) networking and services in existing non-profit institutions indeveloping countries. Others believe that IP telephony has the potential tobenefit the customers through efficient provisioning of converged services on a single network. Consumersare better off if they can make price and quality choices free internet pc to phone along a continuum, inwhich some consumers opt for high quality and high prices, while others chooselow prices and relatively lower quality. In the IP approach, packetloss forms an integral part free internet pc to phone of the concept: SIP is a clientserverprotocol similar in syntax and semantics to the HTTP protocol used by the World-Wide-Webapplication. In fact, three aspects of anew service can be distinguished. EF can offer a sort of virtual"leased line" type service. The LER plays a fundamentalrole in assigning and deleting labels as traffic enters and exits the MPLS network. 10Oftel has powers to impose technical interface standards for telecommunications servicesand interconnection, but has not done so in the case of voip, consistent with its overallpreference for a co-regulatory approach with the industry. Consider whatthe Internet has done for conceiving and spawning innumerable types of web-basedapplications at progressively lower costs. Usually, the common tunneling protocol used islayer 2 Tunneling protocol, and the common encryption mechanism used is Secure socketslayer (SSL).

The network elements in turn acknowledge thesignal positively if they are able to reserve the resources or else send a negativeacknowledgement. EF PHB is defined as a forwardingtreatment for a particular diffserv aggregate, where the departurerate of the aggregateís packets from any diffserv node must equal orexceed a configurable rate. These labels determine the quality ofservice rendered to the packet.
