SSP: Speeding up Small Flows for Proactive Transport in Datacenters

2020

Proactive transports nowadays have drawn much attention because of fast convergence, near-zero queueing and low latency. Proactive protocols, however, need an extra RTT to allocate ideal sending rate for new flows. To solve this, some …

Bridging pre-trained models and downstream tasks for source code understanding

2022 · Proceedings of the 44th International Conference on Software Engineering

With the great success of pre-trained models, the pretrain-then-finetune paradigm has been widely adopted on downstream tasks for source code understanding. However, compared to costly training a large-scale model from scratch, how to effectively adapt …

DC4: Reconstructing Data-Credit-Coupled Congestion Control for Data Centers

2022

Congestion control is crucial for the overall performance of data center networks and still faces considerable challenges. Recently, credit-driven congestion control has been emerging to enable precise flow control for current high-speed and highly dynamic …
