–This paper considers two important aspects related to the control plane of Traffic Engineered IP/MPLS networks: the " flooding reduction " mechanisms and the evaluation of processing cost for signaling and routing protocols. The flooding reduction mechanisms are needed to reduce the amount of information exchanged by Traffic Engineering enabled routing(More)
This paper describes a Session Initiation Protocol (SIP) based solution for mobility management that provides seamless mobile mul-timedia services in a heterogeneous scenario where different radio access technologies are used (802.11/ WiFi, Bluetooth, 2.5G/3G networks). The solution relies on the so called " Session Border Controllers " which are now widely(More)
In this paper we discuss a methodology for performance evaluation of the solutions for vertical handovers between different wireless access technologies in IP network. The performance evaluation is based on simple analytical models and covers both the ideal case (no packet loss) and the real case where there is a given packet loss rate. The methodology is(More)
In this paper we report our two years experience in designing and implementing a new middleware solution for distributed mobile applications exploiting the Session Initiation Protocol (SIP) and the JavaScript Object Notation (JSON). The proposed solution has been designed to port the Simple Middleware Independent LayEr (SMILE) framework to mobile devices(More)
