Scalable Approach to Dynamic SLA Negotiation Mechanism in Protected Shared Mesh Optical Networks

Abstract

This paper investigates the scalability issues concerned with the dynamic SLA negotiation mechanism proposed in the previous study. The previous work presented a dynamic service level agreement negotiation mechanism considering intra- and inter-domain communications over shared mesh optical networks which may cause heavy control overheads in a dynamic environment such as the control plane of GMPLS-based networks. In this paper, two main issues regarding the dynamic propagation of information will be analyzed: i) control overhead, and ii) propagation delay. The paper employs some alternative means of communication to reduce the overheads and resolve the possible scalability issues.
