A Unified Framework for Mining Batch and Periodic Batch in Data Streams

Zirui Liu;Xiangyuan Wang;Yuhan Wu;Tong Yang;Kaicheng Yang;Hailin Zhang;Yaofeng Tu;Bin Cui

IEEE Transactions on Knowledge and Data Engineering

Batch is an important pattern in data streams, which refers to a group of identical items that arrive closely. We find that some special batches that arrive periodically are of great value. In this paper, we formally define a new pattern, namely periodic batches. A group of periodic batches refers to several batches of the same item, where these batches arrive periodically. Studying periodic batch...Show More

Layer-3 load balancing is a key topic in the networking field. It is well acknowledged that flowlet is the most promising solution because of its good trade-off between load balance and packet reordering. However, we find its one significant limitation: it makes the forwarding paths of flows unpredictable. To address this limitation, this article presents BurstBalancer, a simple yet efficient load...Show More

SketchINT: Empowering INT With TowerSketch for Per-Flow Per-Switch Measurement

Kaicheng Yang;Sheng Long;Qilong Shi;Yuanpeng Li;Zirui Liu;Yuhan Wu;Tong Yang;Zhengyi Jia

IEEE Transactions on Parallel and Distributed Systems

Year: 2023 | Volume: 34, Issue: 11 | Journal Article |

Cited by: Papers (1)

HTML

Network measurement is indispensable to network operations. INT solutions that can provide fine-grained per-switch per-packet information serve as promising solutions for per-flow per-switch measurement. The main shortcoming of INT is its high network overhead incurred by collecting INT information, making INT impractical for production deployment. Sketches that can compactly record per-flow infor...Show More

1 Network measurement is indispensable to network operations. Two most promising measurement solutions are In-band Network Telemetry (INT) solutions and sketching solutions. INT solutions provide fine-grained per-switch per-packet information at the cost of high network overhead. Sketching solutions have low network overhead but fail to achieve both simplicity and accuracy for per-flow measurement...Show More
