Scope


Lab performs research on software for telecommunications. Main areas of interest are software engineering methods and tools, software architectures, networks, real time systems, and protocols.

The research spans on both methodological approaches and tools for software architecture specification, design and test, and on the novel applications and features of specific interest for the industrial telecommunication sector, such as protocols for wireless internet access, as well as real time and embedded multiprocessor systems used for switch operative control.

The research activity is organized into strategic projects that involve personnel from ISTI, Pisa University, Scuola S. Anna, and ERI. A number of young researchers will work full time in the laboratory, and will act as the connecting agents between the senior researchers from academia and industry. These projects will consider real world case studies and problems provided by ERI, and develop and experiment on them innovative ideas and techniques.

Projects

Pisatel objectives will be pursued through the joint conduction by the academia and ERI of a set of strategic research projects, that will be selected on an annual basis.
On the one hand, these projects will show up the complex problems and constraints faced by the industrial partner, while on the other, they will provide an effective benchmark for the validation and refinement of the latest research results from the academic labs.
The projects will consider real world case studies and problems provided by ERI, and, although the researchers will be free to experiment innovative ideas and techniques, they will be monitored and reviewed at short term intervals.
Young researchers are recruited to work on the strategic projects.

Integrating Wireless, Wireline and Internet Networks


Three communication networks, namely the emerging "mobile" wireless, the classical "fixed" wireline, and the alternative"computer-centric" internet, are evolving in a relatively independent way. However, their interactions increase day by day.

It is of paramount importance to investigate how these three systems could be integrated so to form a common unique communication space, in which the users of any one of the above networks can easily and "transparently" access the other two.

The main purpose of this project is to investigate such an integration. The initiative is inside the JAIN MAP API international project.

The activities include the implementation of a Java interface for the MAP protocol for wireless networks, and the addition of new services/primitives to JAIN MAP for integrating the three networks into a single communication space.

Analysis and Development of Real Time Software

Many embedded applications have real-time characteristics, as they timely interact with their environment: the response to any event must be provided within a deadline, otherwise some data might be lost.

However, most design methodologies and tools do not currently take into account real-time constraints into the design cycle. Many important design and implementation decisions are still taken based on the designer’s experience.

The objective of this research is to provide a methodology for supporting the design and analysis of real-time applications in the telecommunications domain.

Quality And Validation of Software Architecture


The Software Architecture emerges as a crucial notion to specify and analyze complex systems: SA provides at a high level of abstraction a tractable description of the static and dynamic aspects that are relevant for design decisions and for system-level evaluations

SA = Structure + Behavior


The goal of this project is to develop and experiment rigorous approaches to the early evaluation, testing, and validation of large complex applications centered on the description of the SA.

The investigation also encompasses methods and tools for evaluating the functional and non-functional properties of SAs obtained by the assembly of reused or acquired components, according to the promising paradigm of Component-based Software Engineering.

Emphasis is on the transferability of the proposed methodologies: practical notations, such as UML, and widely used tools are adopted, and prototype tools and technologies are developed.

Video Transcoding


In the last few years, telecommunication systems are gaining increasing importance in everyday life. Many new digital multimedia communication services and devices, such as videomessaging, videoconference, gaming, remote teaching and digital television, have appeared in the market.

It is needed to adapt the media content to different network characteristics, channel bandwidth and access terminals in order to enable delivery with acceptable service quality. Video transcoder's aim is to convey an incoming compressed video bitstream to the outgoing link without the need of fully decoding and re-encoding (a very time- and processing-consuming activity).

A typical application of video transcoding process

Video transcoding converts a compressed video bit stream:

The goal of this project is to develop efficient solutions for achieve an optimal video quality in real-time video transcoding.


Next (third) generation of mobile telephone systems are based on CDMA radio channel access technique that adapt dynamically the channel bandwidth according to the number of users. We investigate new transcoding solutions in order to have a good quality of the video communications forced to smaller channel bandwidth.

We started with studying MPEG-4 video codec and with implementing two temporal video transcoding architectures together with new frame skipping policies. Successively we built an implementation of the same temporal transcoder based on H.263 codec. Moreover, we done an exaustive testing of all architectures combined with all policies.
Currently, we are studying the new H.264 codec and we try to combine the temporal with the quality transcoding.

Network processors


With the growing relevance and pervasiveness of telecommunications, a good deal of interest has been recently drawn by the study of Network Processors (NPs) since they play an important role in the design of modern routers.

Our research explores the main characteristics of the existing NP architectures and the difficulties intrinsic to design software applications for this kind of platforms.

On the other hand we review the basic principles underlying the well-known Model-Based Development approach investigating how such techniques can be applied to embedded systems.

In this context, we have launched a research initiative to investigate the applicability of models and meta-models in the context of NPs.
