2002 - cesnet

Figure 8.6: Example of a detailed summaryFor the deployment in CESNET2, we opted for a Linux PC server. Functionalityof some modules can be improved by a SQL database. We decided to useMySQL. Server is controlled by a scripting language, so its configuration is quitecomplicated. Later on, a web server will be activated, in which it will be possibleto create and administer accounts.The server is intended for calls from SIP clients, to phone lines connected to theprivate branch exchange at CTU + CESNET + ICHT. In addition, there is anotherserver at the Strahov student hostel, ready for use. The hostel will be connectedto the IP telephony network after we solve the issue concerning the authenticationof calls from SIP clients.The existing H.323 network and its clients need to be interconnected with thenew SIP infrastructure. As it is impossible to transfer the entire network to theSIP protocol (for both organisational and technical reasons), we decided for anincremental implementation of SIP in our network, with the use of a H.323/SIPtranslating gateway and a dual configuration of H.323 + SIP within voice gateways.The testing environment, which we are using for the verification of featuresand restrictions of individual products, is described in Figure 8.7.116 High-speed National Research Network and its New Applications 2002
