19 Advantages save 3 messages, save latency, ANDing on the fly As discussed above, active network can merge data from multiple sites and thus reduce traffic flowing on the network. This feature is valuable for real time applications which require very low and predictable response time. We ll explore further the details in implementing ANDing of our bit-oriented DV and PV into active nodes. We expect our research will greatly reduce response time while minimizing the bandwidth requirements in a cost-effective manner. In distributed real time database system, the bandwidth is a shared resources.
Network congestion is inevitable because of the random nature of traffic.
Network congestion will cause information loss. Such mechanisms cannot avoid data loss when the network is in temporal congestion status. This results in uncertain transmission time. The worse case is in broadband database applications because of the large propagation bandwidth product, whereas burst broad bandwidth requirements will likely cause temporal network congestion. Thus we need to work out a new mechanism for our metadata transfer and processing to avoid data loss during temporal congestion.
