Research Problem

The objective of the project is to develop a hybrid switching technology that can connect cell-based ATM, n x 64 kbit/s (PDH/E1, ISDN) and IP traffic simultaneously. The switch is based on FSR technology developed by VTT, and the software is based on an ATM switch controlling software developed in TOVE (Transparent Object Virtual Exchange) project.

Research Plan

The project is divided into two parts. VTT is developing the switch, and HUT is developing the controlling software. The project started early in 1998 and will finish in the end of 2000.

Project Description

Future networks will consist of heterogenous transport solutions. ATM is seen as one of tomorrow's broadband technologies, but to handle interactive multimedia services the transport network must support variety of connections. TOVE project developed an open and standard based infrastructure for ATM networks, and a distributed call and control software for B-ISDN networks. In SCOMS the software is derived to be able to handle also other bearer networks to form a scaleable and flexible controlling software for a multidiscipline switch.The TOVE software is distributed with CORBA, so adding new functionality and new protocols is quite easy and does not need modifications to the old software. SCOMS adds functionality to connecting PDH and ISDN and interworking between them and ATM. Adding IP functionality is an important part of research, and will be implemented during year 2000. OVOPS++ (Object Virtual Operations system ++) -framework, that was developed in TOVE for protocol implementation, is used and further developed in SCOMS.
