This paper introduces a dynamic bandwidth assignment algorithm designed for ring topology (R-DBA) in order to meet the needs of the construction of Metropolitan Area Network (MAN).This algorithm targets ring topology, based on fair iteration, supports various Qos services and has previous assignment mechanism.
Large switched Ethernet networks are deployed in campus networks, data centers and metropolitan area networks to support various types of services. Congestion is usually handled by deploying more switches and installing higher bandwidth link bundles, although a better use of the existing infrastructure would allow to deal with congestion at lower cost. In this paper, we use constrained-based local...
In agile all-optical networks, time division multiplexing in the optical domain is applied on wavelength channels to further divide each wavelength channel into subchannels in order to enable bandwidth virtualization. By introducing intelligent control, agile all-optical networks can serve dynamic and flexible bandwidth on demand. Metro networks with a ring topology are considered, and the protection...
Topology design of metro Ethernet networks is a constrained optimization problem, so we need to consider multiple criteria with different units, simultaneously. In this paper, we define three major criterions: load balancing over links, load balancing on switches and shortest path selection. We can weigh the importance of each criterion based on our goal. We study a design method of network topology...
Wireless mesh networking technology has gained prominence in recent years with a diverse range of applications from small community-based networks to metropolitan area networks. Such mesh networks typically comprise a wireless backbone connected to the wired infrastructure with wireless client residing at the edge. The wireless routers and access points of a wireless mesh network (WMN) are connected...
