Openflow-based server load balancing gone wild

by Richard Wang, Dana Butnariu, Jennifer Rexford - In Proceedings of the 11th USENIX conference on Hot topics in management of internet, cloud, and enterprise networks and services , 2011
"... Today’s data centers host online services on multiple servers, with a front-end load balancer directing each client request to a particular replica. Dedicated load balancers are expensive and quickly become a single point of failure and congestion. The OpenFlow standard enables an alternative approa ..."

Constructing Load-Balanced Data Aggregation Trees in Probabilistic Wireless Sensor Networks

by Jing (selena He, Shouling Ji, Yi Pan, Yingshu Li
"... Abstract—Data Gathering is a fundamental task in Wireless Sensor Networks (WSNs). Data gathering trees capable of performing aggregation operations are also referred to as Data Aggregation Trees (DATs). Currently, most of the existing works focus on constructing DATs according to different user requ ..."

Power System Dynamics as Primal-Dual 1 Algorithm for Optimal Load Control

by Changhong Zhao, Ufuk Topcu, Na Li, Steven H. Low , 2013
"... We formulate an optimal load control (OLC) problem in power networks where the objective is to minimize the aggregate cost of tracking an operating point subject to power balance over the network. We prove that the swing dynamics and the branch power flows, coupled with frequency-based load control, ..."

Swing dynamics as primaldual algorithm for optimal load control

by Changhong Zhao, Ufuk Topcu, Steven Low - California Institute of Technology , 2012
"... Abstract—In electricity transmission networks, loads can pro-vide flexible, fast responsive, and decentralized sources for frequency regulation and generation-demand balancing, com-plementary to generation control. We consider an optimal load control (OLC) problem in a transmission network, when a d ..."

A Distributed Learning Automata based Gateway Load Balancing Algorithm in Wireless Mesh Networks

by Maryam Kashanaki, Zia Beheshti, Mohammad Reza Meybodi
"... Abstract Wireless Mesh Networks (WMNs) are a rapidly maturing technology for providing high bandwidth broadband service to a large community of users. In WMNs, gateway nodes act as a central point of connectivity to the wired infrastructure (typically the Internet). Therefore traffic aggregation occ ..."

Node Load Balance Multi-flow Opportunistic Routing in Wireless Mesh Networks

by Ifsa Publishing, Wang Tao, Li Wenwei, He Shiming , 2014
"... Abstract: Opportunistic routing (OR) has been proposed to improve the performance of wireless networks by exploiting the multi-user diversity and broadcast nature of the wireless medium. It involves multiple candidate forwarders to relay packets every hop. The existing OR doesn’t take account of the ..."

With node load balance constraint, NMOR allocates the flow rate iteratively and the rate allocation decides the candidate forwarder selection of opportunities routing

Balanced Relay Allocation on Heterogeneous Unstructured Overlays

by Hung X. Nguyen, Daniel R. Figueiredo, Matthias Grossglauser, Patrick Thiran
"... Abstract — Due to the increased usage of NAT boxes and firewalls, it has become harder for applications to establish direct connections seamlessly among two end-hosts. A recently adopted proposal to mitigate this problem is to use relay nodes, end-hosts that act as intermediary points to bridge conn ..."
