Layered PCE based multi-domain optical network secure light path establishment protocol

Abstract

The invention discloses a layered PCE based multi-domain optical network secure light path establishment protocol. Aiming at the problems of security problem and comprehensive efficiency existing in a multi-domain optical network light path establishment process, a new GO-PCE (Global Optimizing secure light-path protocol based PCE in multi-domain optical network) is designed by combining with a trust model and a key management scheme, adopting a globally optimized multi-domain trusted path selection, usable wavelength calculation and wavelength distribution strategy, and utilizing a TLS based bidirectional identity authentication, TCP-AO based source authentication, identity cryptography based encryption and digital signature technology and a Path-Key based privacy protection mechanism. The secure service requirements such as confidentiality, completeness, authenticity, non-repudiation, freshness and privacy can be met; compared with an SD-PCE and pH-PCE light path establishment protocols, the layered PCE based multi-domain optical network secure light path establishment protocol has relatively low blocking rate and relatively short light path establishment time delay.

Description

technical field [0001] The invention relates to the technical field of multi-domain optical networks, in particular to a multi-domain optical network security optical path establishment protocol based on layered PCE. Background technique [0002] In 2009, the IETF proposed the security requirements for the establishment of optical paths in multi-domain optical networks in RFC 5520, but no relevant effective solutions were proposed. In 2009, Professor Zhou Xianwei of Beijing University of Science and Technology proposed an ASON secure optical path establishment protocol, but this protocol is only suitable for single-domain optical networks. In 2004, Sun Weiqiang proposed a hybrid mode-based cross-domain optical path establishment protocol CLEP in literature [34]. In 2014, Wang Zongwei [35] A scheme to establish a cross-domain optical path based on SD-PCE and pH-PCE was proposed. In the same year, Qiu Zaimeng [36] Cross-domain solutions based on PCE-based optical networks ha...
