    For over 30 years of its existence, the Internet has evolved from traditional data networks in the largest multiservice networks. Some Internet service has been created from scratch (like e-mail), some of them (eg. television, or Internet telephony) is the adaptation of services previously implemented in specialized networks (broadcast television network, Plain Old Telephone Service - POTS, etc.). Implementation of new services is a complex issue. New services may interact with existing applications. Problems can also occur with services adapted from specialized networks - for example, due to much lower transmission quality than required. In this paper an analysis of contemporary services and requirements is described. We show problems, which occur due to the heterogeneity of multiservice network, as well as how to solve these problems.
