An Efficient Storage Technique for Network Monitoring Data
Telecom operators have to constantly monitor the network for a number of tasks, such as billing, management, provisioning, dimensioning, etc. Some of these tasks such as billing require the analysis of the data in near real-time, while others are performed a posteriori on historical data sets. Monitoring modern networks involves storing and transferring huge amounts of data. For this reason, compression techniques are typically used in order to reduce the space and time needed for these operations. The main drawback of this approach is that, when data has to be processed, a preliminary decompression is necessary, which increases the time and computational power needed.
