JGN-X

The aim of expansion of Openflow in the JGN-X testbed is to advance the research and development environment for New Generation Network by implementing the New Generation Network (NwGN) technology on JGN-X and to build a integrated management operation system on it.

• To build a New Generation Network technology as a testbed
  – To propose, build, and test the networking model for service providers
     and carriers through operational management
  – To propose a model for a Virtual Network Operator
• Network Infrastructure for Cloud Computing
  – Efficient usage of computer resource by collaborating with virtual server
     and storage systems
• Manage user traffic by Flow*
  – Unlike legacy VLAN management, this system is able to avoid VLAN tag
     exhaustion problems
• To able to provide automated slice allotment for users
  – To be able to choose which network resource users want to use

One of the challenges that may be solved by various experiments on this testbed is the challenge of dynamic flow management technology.

Figure below is the layers to the network virtualization environment which Openflow testbed aims to build on the JGN-X network.

Usage of Openflow testbed as one of the networks to transmit video content between broadcasting companies.

• Year 2010
  Building the first wide area Openflow network
• Year 2011
  Using dynamic flow management to manage operation on a wide area testbed network

The JGN-X is to make experiments to extract necessary conditions to make a effective testbed for users. In this experiment, necessary items from both users and operators are needed to find and adopt.
