Title:Study of Multiple Path Discovery Approach for Mass Data Transmission in Next Generation Wide Area Layer2 Network
Abstruct:Currently, bandwidth allocation of VLAN path in Wide Area Ethernet depends on link bandwidth. Aggregation of multiple end-to-end paths is effective to avoid this limit. This paper proposes multiple independent paths discovering method using extended Ethernet frame flooding technique in next generation Wide Area Ethernet which virtually enables high capacity transmission by aggregating multiple paths. Implementing the algorithm to software switches and evaluates the delay of discovered multiple paths.

Title:A Study of Parallel Transmission Technique with GMPLS in Intelligent Cloud Network
Abstruct:With the appearance of the cloud network, high speed data communication among data centers is necessary. However, because the data is transmitted through the Internet, network bandwidth is not enough. To construct large bandwidth WAN at low cost, we propose an Intelligent Cloud Network. In the Intelligent Cloud Network, data delivered with parallel transmission and lower cost private lines that are lower bandwidth are applied as multiple routes. In this paper, we propose parallel transmission system. In this system, parallel routes are set up with GMPLS. The proposed system is implemented on the software switch to evaluate parallel transmission.

Title:A Protection Scheme with Double Optical Trees in Active Optical Access Network
Abstruct:We study a novel optical access network with active optical switches, called ActiON (Active Optical Network), as a next generation access network to replace PON (Passive Optical Network). In this paper, we focus on the reliability of optical access networks and propose a protection scheme for ActiON by connecting two ActiON trees. Finally we discuss the availability and the component cost of the proposed architecture.
