Optimizing Congestion Control by using Devices Authentication in Software-Defined Networks

Congestion Control Using OpenFlow in Software Defined Data Center Networks

this paper studies congestion control issue in data center networks and proposes a potential solution based on OpenFlow protocol. A main feature of the emerging data center networks is their performance in hosting different cloud applications and services. Since congestion management is necessary to effectively utilize numerous data center applications, in this paper we present an efficient met...

Authentication and Access Control Architecture for Software Defined Networks

In this work, we propose a host authentication and access control architecture for software defined networks. The key idea is to authenticate at Layer 2, using IEEE 802.1X standard and Extensible Authentication Protocol (EAP). EAP exchanges authentication information between the supplicant host and a RADIUS authentication server. We developed the proposed authenticator as an OpenFlow applicatio...

Control in Software - Defined Networks

Control traffic balancing in software defined networks

To promise on-line and adaptive traffic engineering in software defined networks (SDNs), the control messages, e.g., the first packet of every new flow and network traffic statistics, should be forwarded from software defined switches to the controller(s) in a fast and robust manner. As many signaling events and control plane operations are required in SDNs, they could easily generate a signifi...

A profit optimizing strategy for congestion control in signaling networks

Congestion control in the signaling system number 7 (SS7) is a necessity to fulfil the requirements of a telecommunication network that satisfy customers’ requirements on quality of service. Heavy network load is an important source of customer dissatisfaction as congested networks result in deteriorated quality of service. With the introduction of a Congestion Control Mechanism (CCM), that ann...
