....Page 5 internet address translation, and checksum implementation. Bhar ] They found the socket layering and connection to be the most expensive categories. 2.4 Using Silence Deletion Rabiner viewed voice as a measure of energy and presented an algorithm for discovering the endpoints of words. [Rabi75] Henning Schulzrinne implemented an audioconferencer with silence deletion. Schu92] Their deletion algorithms is an adaptive form of the HAM algorithm (see Section 3.2.4 of the present document) 2.5 Our Contributions We measure the per byte CPU loads for several basic operations (Read, Send, ....

....adding sound packets that arrive simultaneously. Writing is the CPU load for delivering the incoming samples to the audio device. Our model asserts we can predict audioconference CPU load from the sum of the above pieces. 3.2 Silence Deletion Silence deletion treats sound as a measure of energy. [Rabi75] It views the energy in one of three ways: 1. The energy of each byte (b[i] 2. The average energy over many bytes (power) 3. The changes in energy. Equations for the three methods are: Method 1: Read Silence Send Receive Add Write Deletion (microphone) speaker) FIGURE 1. Our ....
