Addressing and secure control-plane network design in GMPLS networks
1: This document describes a control-plane network design for general scalable GMPLS networks. We use the Circuit-Switched High-speed End-to-End ArcHitecture (CHEETAH) network as an example to illustrate how we implemented our design. The CHEETAH network is a Synchronous Optical NETwork (SONET) based network that uses Sycamore SN16000 switches. While some of the specifics related to this switch...
متن کاملGMPLS-Based Control Plane for Optical Networks: Early Implementation Experience
Generalized Multi-Protocol Label Switching (GMPLS) extends MPLS signaling and Internet routing protocols to provide a scalable, interoperable, distributed control plane, which is applicable to multiple network technologies such as optical cross connects (OXCs), photonic switches, IP routers, ATM switches, SONET and DWDM systems. It is intended to facilitate automatic service provisioning and dy...
متن کاملControl Plane Protection Using Link Management Protocol (LMP) in the ASON/GMPLS CARISMA Network
In the ITU-T ASON architecture, the control plane is responsible for providing intelligence to the network. The GMPLS paradigm pleads for a separation between the control plane and the forwarding plane. If the control plane is deployed disjoint from the forwarding plane, recovery mechanisms to ensure its proper operation are required. In this paper, on one hand, a quasi-associated mode backup c...
متن کاملGMPLS Control Plane Auto-discovery Evaluation and Its Interfacing with OSS in IP Optical Network
This paper compared the auto-discovery functionality between GMPLS and ASON, and found the current LMP in GMPLS needs to be modified to meet with the requirements of the ITU-T standard. To efficiently communicate the auto-discovered information between the control plane and the management plane, we proposed the interface between the two planes should be standardized.
متن کاملRecovery from control plane failures in GMPLS-controlled optical networks
The health status of the control plane and the data plane of a GMPLS-controlled optical network is independent in the physically separated control network implementation. In most control plane designs, besides the topology information, the entities of the routing protocol only record the number of available wavelengths on each link. However, the status of each wavelength is maintained by the en...
