IP Telephony and Reliability: Protecting Mission-critical Phone Systems from Power Threats

Thu, 01 Jan 1970 00:00:00

IT managers who are used to implementing power protection for IT network or data center applications face new challenges in protecting their enterprise IP telephony systems. Users demand the same high level of reliability for IP telephony and its converged voice/data/ video applications as they demand from the conventional phone systems that IP telephony replaces.

IP telephony equipment in remote wiring closets is typically less secure, less protected, and far more apt to be at risk from higher repair times. Accordingly, IT managers must consider the complete protection system required to provide a high-availability system. The six requirements for achieving high-availability in wiring closets and other remote locations are:

Power quality
System redundancy
Precision cooling
Remote monitoring and management
Physical security of system equipment
Mission-critical service

Proxy-Driven Rate-Distortion Optimized Video Streaming Over Wireless Network Using Asynchronous ...

Thu, 01 Jan 1970 00:00:00

Video streaming over wireless network is challenging due to node mobility and high channel error rate. This paper proposes a joint server/peer, proxy-driven video streaming architecture to support high quality video streaming service over IEEE 802.11-based wireless networks. The video proxy tracks peer mobility pattern, coordinates among multiple senders and performs rate-distortion optimized streaming. The joint server /peer streaming is formulated as a combinatorial optimization problem and the paper introduces the concept of asynchronous clocks to decouple the problem into three steps: first deciding the candidate set of potential senders among the wireless peers based on their mobility pattern, then selecting the sender in each optimization instance using asynchronous clocks, and finally applying point-to-point rate-distortion optimization framework between the selected sender-receiver pair.
