The Essential Report on IP telephonygeneral costing and pricing issues 57III. Thus, the packet will have a level of free long distance pc to phone priority in the router transmission queuecorresponding to the requested quality of service. An LSR is a high-speed router within an MPLS networkwhich is involved in setting lsps. The ipsec security association is a connection which provides securityservices for the traffic it transports. Two basic abstractions are used in that model: The Modify commandallows the MGC to modify properties, signals and events of a given termination. The imposition by national regulatory authorities of mandated access that increasescompetition in the short term should not reduce incentives for competitors to invest in alternativefacilities that will secure more competition in the longer term.

Traffic Shaping andpolicingtraffic shaping ensures that the traffic entering the network conformsto the agreed flow characteristic. Phbs are implemented using buffer and schedulingmechanisms.
The work was organized as follows: The evolution to IP-based networks canbe accomplished economically by deploying IP-based packet switches/routers that can beconnected by existing transport facilities. "The combination of the term "Internet" with the term "telephony" is seen as inappropriate. Later in this document, we shall be focusing on the discussion of problemsrelating to implementation of the IP telephony service and to the ways in which the PSTN andnetworks using IP technology interact. 7 Even though access servers to the Internet have been largely deployed in developed countries and traffic towards ispsswitched off from the telephony network as early as possible (congestion avoided at transit level), two problems remain:
