Seamless end-to-end Ethernet VLAN path provisioning over multi ASON and GMPLS network domains is successfully achieved. Two interworking scenarios 1) ASON and GMPLS, 2) GMPLS and GMPLS are confirmed in both control and data planes.
A novel OSNR-based IRWA algorithm and the required GMPLS extensions for dynamic provisioning in translucent WSON are presented. Experimental evaluation and validation in the ADRENALINE test-bed shows an important blocking reduction compared to transparent networks.
This paper describes a multi-layer network management system for an IP/MPLS/GMPLS network, which provides integrated control and management from a packet to a lambda, even under a multi-vendor environment. The developed proto-type NMS successfully demonstrated such integrated topology management and hierarchical resource management of IP flow, MPLS LSPs and GMPLS LSPs. In addition, targeting the effective...
Traffic engineering in backbone networks is an important issue in supporting an appropriate QoS level to accommodate various types of traffic flows efficiently. Automatically switched optical networks and generalized multiprotocol label switching control planes are promising functionalities to achieve the sophisticated mechanism of interdomain traffic engineering. In this article we address dynamic...
Dynamic protection mechanism was proposed to provision each individual LSP in a group LSP with differentiated survivability. A resilient multi-QoS burst streams transmission over the group LSP was demonstrated in a GMPLS-controlled transparent optical network.
We present test results for all-optical switching transport network based on GMPLS. A LMP-WDM interworking operation between DWDM and PXC was indicated to improve reliability and manageability.
The GMPLS/OXC network testbed of JGN II is introduced from the viewpoint of GMPLS network architecture as well as actual network operation. The advanced experimental results of IPv6/GMPLS and MPLS/GMPLS interworking are described using this testbed. Ongoing research projects are introduced and the future view of GMPLS development is also discussed considering the results of the demonstration and operational...
