The SNMP source code was modified so we could poll the encoder boxes for information concerning CPU temperatures, fan speeds and voltages. Thanks to Linux, we did not need to make any expensive maintenance requests of vendors. Given these fine freely available tools, we can detect and fix trouble without the customer even knowing that anything was wrong. One last Linux feature needs to be mentioned before closing. We shape the traffic on our pipe while the audio signal moves through our network toward the Internet.
Sound quality depends on available bandwidth.
The audio signal shares the pipe with monitoring and management traffic. Under normal circumstances, this should not present a problem. However, should a sudden surge in log activity occur or a new software package be sent back up the line, traffic shaping allows us to ensure it does not cut into the bandwidth required for our customer's broadcast. Global Media Corporation produces the best audio signal possible for Internet listeners, while providing a cost-effective solution to broadcasters. Without Linux, we could not have achieved all we have as cheaply and effectively.
