Outlines of current research
SDN concept
SDN concept

The Internet traffic becomes explosive due to endless request from users. Network administrators have to cope with a lot of difficulties to support the request. They have to learn configuration based on product's manual. Implementation of a new solution is difficult due to the limitation of product operating system. We study network technologies to make the network easier to be controlled, implement, and less complex.

Software Defined Networking

SDN separates the network control and data forwarding planes. This allows network engineers and administrators to respond quickly to changing requirements of the network from a centralized controller. The network administrator can avail of improved network programmability to flexibly control the physical switches from the controller, which runs all the intelligent control and management software, regardless of the vendor or the model of the switches used.

OpenFlow is a widely known protocol for SDN networks that enables the controller to interact with the forwarding plane of the switches and thus make adjustments to the network. The hardware switches can also use OpenFlow messages to inform the controller when a packet arrives with no specified forwarding instructions. The forwarding instructions are based on a flow entry. The controller specifies the set of parameters and how packets that match the flow entry should be processed.

Optical packet/burst switching

Optical packet switched networks are emerging as a serious future candidate for the evolution of optical telecommunication networks to support high-throughput services such as voice over IP (VoIP) and high quality video streaming on demand. In an optical network with optical packet switches interconnected with optical fibers running wavelength division multiplexing (WDM), packets are transmitted from source to destination without any optical-electrical-optical (O/E/O) conversion.

Buffering at intermediate nodes is eliminated. The use of optical buffering through fiber delay lines (FDLs) to delay a packet for a specified amount of time while waiting for a future transmission may not feasibly to provide a large delay time.

Network control and management

In an IP network, a packet travels from source to destination using a routing table to guide a route. The routing table is dynamically configured using a routing protocol based on traffic condition. Adopting a suitable routing scheme can gain higher network throughput.
