In these exercises, you will explore some basic multicast concepts via simple IP multicast applications that have been in usage for several years and are known as Mbone tools. The Mbone was the original implementation of IP multicast on the Internet. In these exercises all the hosts (your PCs) are connected to the same LAN—no multicast routing is needed at this stage. | A Laboratory Exercises-Applications and IP Multicast Overview In these exercises you will explore some basic multicast concepts via simple IP multicast applications that have been in usage for several years and are known as Mbone tools. The Mbone was the original implementation of IP multicast on the Internet. In these exercises all the hosts your PCs are connected to the same LAN no multicast routing is needed at this stage. It includes the following exercises Laboratory Exercise A-1 Session Announcements Laboratory Exercise A-2 Audioconferencing RAT and Whiteboarding WB Laboratory Exercise A-1 Session Announcements Objective The objectives of this laboratory exercise are With a short overview and some experimentation with the IP multicast SDR application from the Mbone tool set you will learn how session announcements are used and how actual multicast applications for example audioconferencing and whiteboarding are started. You will create and observe your own sessions. Prerequisites The software for the next exercises is already installed on the workgroup PCs. Installed MBone applications can also be found on the following URL http multimedia software Note The current version of these tools will not run on Windows 95 platform unless it has the Winsock2 Upgrade for Windows95 which is available from Microsoft at http windows95 downloads contents wuadmintools s_wunet workingtools w95sockets2 Task 1 Multicast Session Directory SDR SDR is a session directory tool designed to allow the advertisement and joining to multicast conferences. Step 1 For this exercise launch the SDR application from Start- Programs- Mbone Tools- sdr menu or launch C Program Files Mbone from the command line or Microsoft Explorer and observe the multicast sessions that are being advertised on the network. After starting the SDR application a similar display to Figure 1 will appear. SDR listens and announces multicast sessions on the .
