Abstract. This paper presents the researches for better integration between services and networks by simplifying the network layers structure and extending the ontology use. Through an ontological viewpoint, FINLAN (Fast Integration of Network Layers) was modeled to be able to deal with semantics in the network communication, cross-layers, as alternative to the TCP/IP protocol architecture. In this research area, this work shows how to integrate and collaborate with Future Internet researches, like the Autonomic Internet.

Given the growing need for interoperability among various communication services (IP, PSTN, PLMN), ENUM technology has become fundamental to the development of VoIP services. Through modeling and simulation, this paper presents a performance study of the ENUM protocol considering the response time for E.164 numbers resolution which is an important performance requirement that is directly linked to the connection establishment time in VoIP systems. The scenarios include the study of TTL influence, retransmission timeouts for lost queries, distribution of the number of hops, etc. Simulation results allowed us to find a good value of TTL for ENUM protocol. We also found that the distribution of the number of hops is one of the most important factor that impact the response time.
