The Internet has historically been built on the assumption of a smart edge and a dumb network. This design philosophy is also reflected in end-to-end Internet congestion control. The stability and general fairness of the current Internet are heavily ...

The Internet congestion control landscape is rapidly evolving. Since the introduction of BBR and the deployment of QUIC, it has become increasingly commonplace for companies to modify and implement their own congestion control algorithms (CCAs). To ...

Since its introduction in 2015, QUIC has seen rapid adoption and is set to be the default transport stack for HTTP3. Given that developers can now easily implement and deploy their own congestion control algorithms in the user space, there is an imminent ...

Packet loss due to link corruption is a major problem in large warehouse-scale datacenters. The current state-of-the-art approach of disabling corrupting links is not adequate because, in practice, all the corrupting links cannot be disabled due to ...

The QUIC standard is expected to replace TCP in HTTP 3.0. While QUIC implements a number of the standard features of TCP differently, most QUIC stacks re-implement standard congestion control algorithms. This is because these algorithms are well-...

Since its introduction in 2016, BBR has grown in popularity rapidly and likely already accounts for more than 40% of the Internet's downstream traffic. In this paper, we investigate the following question: given BBR's performance benefits and rapid ...

Packet corruption loss is a serious problem in datacenter networks. A large-scale study by Microsoft reported that the number of packets lost due to corruption is comparable to those lost due to congestion. Previous attempts to mitigate the impact of ...

In 2016, Google proposed and deployed a new TCP variant called BBR. BBR represents a major departure from traditional congestion control as it uses estimates of bandwidth and round-trip delays to regulate its sending rate. BBR has since been introduced ...

In 2016, Google proposed and deployed a new TCP variant called BBR. BBR represents a major departure from traditional congestion control as it uses estimates of bandwidth and round-trip delays to regulate its sending rate. BBR has since been introduced ...

In 2016, Google proposed and deployed a new TCP variant called BBR. BBR represents a major departure from traditional congestion-window-based congestion control. Instead of using loss as a congestion signal, BBR uses estimates of the bandwidth and round-...

Automated program repair has been used to provide feedback for incorrect student programming assignments, since program repair captures the code modification needed to make a given buggy program pass a given test-suite. Existing student feedback ...

Microbursts can degrade application performance in datacenters by causing increased latency, jitter and packet loss. The detection of microbursts and identification of the contributing flows is the first step towards mitigating this problem. ...

TCP does not work well in modern cellular networks because the current congestion-window-based (cwnd-based) congestion control mechanism intimately couples congestion control and packet dispatch, which provides TCP with only indirect control of the ...

Neighbor discovery is essential for docking applications, where mobile nodes communicate with static nodes situated at various rendezvous points. In existing neighbor discovery protocols, the probabilistic protocols perform well in the average-case but ...

Recent advances in unmanned aerial vehicle (UAV) technologies have made it possible to deploy an aerial video surveillance system to provide an unprecedented aerial perspective for ground monitoring in real time. Multiple UAVs would be required to cover ...

We study the performance impact of the Message in Message (MIM) mechanism in modern 802.11 networks. The MIM mechanism refers to the capability of receiver to abandon an ongoing reception of an 802.11 MAC frame and shift to decode another frame with a ...

With the significant increase in cellular data usage, it is critical to better understand the characteristics and behavior of cellular data networks. With both laboratory experiments and crowd-sourcing measurements, we investigated the characteristics ...
