Lab Trial of Multi-Domain Path Computation in GMPLS Controlled WSON Using a Hierarchical PCE
Optical communications Networks assignment routing algorithms.
2015/5/21
We report the design, implementation and lab-trial of an H-PCE for multi-domain path computation in GMPLS networks and the required PCEP protocol extensions. We quantitatively show the benefits of par...
Evolutive Lightpath Assessment in GMPLS-controlled Transparent Optical Networks
GMPLS-controlled Transparent Optical Network Lightpath Assessment
2015/5/15
A method to mix impairments estimations and in-field measured data is proposed to evaluate the Quality of Transmission of new lightpaths. It is applied before lightpath establishment and increases the...
Point-to-Multipoint VLAN path signaling demonstration on the GMPLS controlled Ethernet test network
Networks multicast Optical communications
2015/6/5
This paper provides the demonstration of GMPLS controlled Point-to-Multipoint Ether-net path establishment. The prototype RSVP-TE is extended for supporting peer and overlay model networks. Detailed R...
Efforts of standardization bodies illustrate that Ethernet is conquering carrier environments. Resulting technologies intend to overcome Ethernet bridging limitations. Validated through emulation, we ...
Segment Restoration Scheme with QoT-guarantees in GMPLS-controlled Translucent Networks
QoT-guarantees GMPLS-controlled Translucent Networks
2015/8/3
The paper proposes and evaluates a segment restoration scheme exploiting regenerators used in provisioning. The scheme guarantees seamless quality of transmission (QoT) in failure-prone dynamic GMPLS-...
