Traffic sampling has become an indispensable tool in network management. While there exists a plethora of sampling systems, they generally assume flow rates are stable and predictable over a sampling period. Consequently, when deployed in networks with dynamic flow rates, some flows may be missed or under-sampled, while others are over-sampled. This paper presents the design and evaluation of dSamp, a network-wide sampling system capable of handling dynamic flow rates in Software-Defined Networks (SDNs). The key idea in dSamp is to consider flow rate fluctuations when deciding on which network switches and at what rate to sample each flow. To this end, we develop a general model for sampling allocation with dynamic flow rates, and then design an efficient approximate integer linear program called APX that can be used to compute sampling allocations even in large-scale networks. To show the efficacy of dSamp for network monitoring, we have implemented APX and several existing solutions in ns-3 and conducted extensive experiments using model-driven simulations. Our results indicate that, by considering dynamic flow rates, APX outperforms the existing solutions by up to 10% in sampling more flows at a given sampling rate.

In the era of big data, distributed key-value stores are widely used in various fields. These systems efficiently store and manage massive amounts of data by distributing data across different. It also splits data into multiple fine-grained shards for management purposes. However, the minimum unit of hardware resource usage perception is the node because it is difficult to measure the hardware resource usage of the shard since it is a logical structure, and the corresponding data is scattered in different locations in the nodes. This inconsistency in granularity leads to challenging hardware resource usage management while the unit of management is shard. To solve this problem, we propose a new hardware resource usage measurement framework FDHM, which integrates a measurement model based on the shard and node attributes and a dynamic attribute update mechanism to achieve fine-grained and dynamic measurement. We implemented a lightweight integration of FDHM on TiKV and tested it. Experimental results show that FDHM significantly improves the accuracy of hardware resource usage measurement compared with existing methods. And we also verified its benefits in resource management through a case study.
