This paper proposes new joint flow control and link scheduling (JFCLS) algorithms for the classical network utility maximization (NUM) problem with unknown utility functions. Our algorithm leverages the idea of optimism, i.e., being optimistic in using ...

Permissionless reputation-based distributed ledger technologies (DLTs) have been proposed to overcome blockchains’ shortcomings in terms of performance and scalability, and to enable feeless messages to power the machine-to-machine economy. These DLTs ...

Abstract: Pumps and valves are generally indispensable parts of the hydraulic system and a component that integrates the functions of pumps and valves plays an important role in the integration and lightweight development of hydraulic systems. In this ...

Incast occurs frequently in datacenter networks where a large number of senders send data to a single receiver simultaneously, which makes the last hop the network bottleneck. Incast can hurt flows' performance. However, congestion control protocols are ...

Congestion detection is the cornerstone of end-to-end congestion control. Through in-depth observations and understandings, we reveal that existing congestion detection mechanisms in mainstream lossless networks (i.e., Converged Enhanced Ethernet and ...

In microservice systems, availability can be ensured through a variety of measures, such as fault tolerance and flow limiting, which are collectively called the flow control. In the current mainstream system design, the flow control rules are ...

Filling liquefied natural gas (LNG) into the vehicles onboard tanks is one of the most dangerous production operations when using LNG as a motor fuel. Technical requirements form the volume of hazardous substance (LNG) stored at the refueling ...

Flow-control policies that balance server loads are well known for improving performance of queueing systems with multiple nodes. However, although load balancing benefits the system overall, it may negatively impact some of the queueing nodes. For ...

This article discusses the events that led to the publication of my paper 'A Control-Theoretic Approach to Flow Control' that won the Best Student Paper Award in 1991 and a Test-of-Time Award in 2007.

This article discusses my personal view of the events that led to the publication of the paper "Analysis and Simulation of a Fair Queueing Algorithm" that won a Test-of-Time Award in 2007.

Many applications in distributed systems rely on underlying lossless networks to achieve required performance. Existing lossless network solutions propose different hop-by-hop flow controls to guarantee zero packet loss. However, another crucial problem ...

Variable buoyancy system (VBS) is important for long-range autonomous underwater vehicles (AUVs) to adjust the buoyancy change caused by environmental density changes dynamically, and it is the core component of AUV to realize near-neutral buoyancy ...

The paper considers the model of a network with the nodes being one-server queueing systems. Non-stationary Poisson flows (traffic flows) are input flows to some queueing systems. A statistical simulation algorithm is proposed. It identifies weak points ...

In today's modern datacenters, the waiting time spent within a server's queue is a major contributor of the end-to-end tail latency of μs-scale remote procedure calls. In traditional TCP, congestion control handles in-network congestion, while flow ...

The present study numerically investigates the effect of a partially covered cylindrical shield on the flow/shock oscillation characteristics of a Hartmann whistle when the pulsating jet exits through the two small openings, a close to the cavity inlet, ...

The gap is widening between the processor clock speed of end-system architectures and network throughput capabilities. It is now physically possible to provide single-flow throughput of speeds up to 100 Gbps, and 400 Gbps will soon be possible. Most ...

Software-Defined Network (SDN) is a novel architecture created to address the issues of traditional and vertically integrated networks. To increase cost-effectiveness and enable logical control, SDN provides high programmability and centralized view of ...

This memo updates RFCs 4251, 4252, 4253, and 4254 by defining a mechanism for Secure Shell (SSH) clients and servers to exchange information about supported protocol extensions confidentially after SSH key exchange.

Network calculus is a methodology to analyse queueing networks in a (probabilistic) worst-case setting. To that end, many results have been

presented for different arrival and service processes and under different network topologies. Yet, in the ...

TCP performs slow start phase based on an exponential increase of the congestion window to predict the current network. Current TCP slow start does not work well under large bandwidth networks. The exponential growth of slow start phase cause burst ...
