An Integrated Multi-service Software Simulation Platform: SIMPSONS Architecture

2005

This paper describes SIMPSONS (SIp and MPls Simulations On NS-2), which is a software platform for simulating multiple network scenarios, such as Telephony Over IP (TOIP), and multi-services networks extending the functionalities of Network Simulator NS-2. The innovative aspects of SIMPSONS is the complete integration of control protocols and traffic engineering mechanisms inside the same simulation tool. In fact, next generation networks must meet basically two fundamental requirements: support of Quality of Service (QoS) and Traffic Engineering (TE) functionalities. SIMPSONS is able to simulate DiffServ, MPLS, OSPF and SIP and their interaction in everything TOIP scenario. So with this po…

Congestion Avoidance Using DYnamic COdec MAnagement: A solution for ISP

2005

The large diffusion of VoIP is an essential key for the success of emerging Internet service providers. These ISPs conflict with the interests of historical and predominant network maintainers which often control the network infrastructure and telephone services. To win this competition, emerging ISPs have to adopt strategic QoS solutions which will capture the attention of network users and phone clients. This paper presents a solution which is able to obtain the same performance of a 64 Kbps channel reducing the costs for over-provisioning network bandwidth. DyCoMa is a mechanism studied for VoIP applications in network with a limited bandwidth for multimedia services. It works preventing…

Transport service for session initiation protocol in SIP-T scenarios

2005

The traditional telephone service has undergone deep changes in the years concerning the techniques of commutation and signaling. Today, public switched telecom networks (PSTNs) and private integrated services networks (PINSs) are strongly directed to adopt IP-based backbone. If it is possible to transfer the voice on packet switching network, in such reliable way, using voice over IP (VoIP) techniques, there is not still a valid alternative to the signaling systems, reliable and unfailing, like signaling system n.7 (SST). Session initiation protocol (SIP) seems to be the best candidate. SIP is an application layer signaling protocol and the problem remains still opened for what it concerns…
