Abstract

The invention discloses an inter-domain intercommunication control system of heterogeneous optical networks, comprising multiple inter-domain intercommunication devices, a network management device and adaption unit devices; the inter-domain intercommunication devices comprise memory cells for storing computer programs and storing network information databases and configuration files supporting the inter-domain intercommunication devices to realize related functions; communication units for realizing the communication between the inter-domain intercommunication devices and the network management device, the communication among the adaption unit devices, and the intercommunication among the multiple inter-domain intercommunication devices; encryption units for carrying out authority authentication to users of the inter-domain intercommunication devices and encrypting and decrypting the communication data among the multiple inter-domain intercommunication devices; central control units for controlling the inter-domain intercommunication devices according to the computer programs stored in the memory cells and processing the communication data of the communication units. According to the system of the invention, the intercommunication among multi-domain heterogeneous optical networks is conveniently managed and controlled.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a control system for inter-domain intercommunication of heterogeneous optical networks. Background technique [0002] Optical fiber networking technology has been widely used in the core network due to its advantages of large capacity, high bandwidth, extremely low transmission loss, and strong anti-interference ability. [0003] At present, the core optical network is characterized by a high degree of heterogeneity, that is, the entire network system is jointly operated by multiple vendors, the entire network system has network equipment manufactured by multiple vendors, and the entire network system uses transmission systems developed by multiple vendors. This makes it difficult to achieve joint management and control between different network domains, which leads to insufficient security and low efficiency of the current intercommunication and interconnection between he...

[0003] At present, the core optical network is characterized by a high degree of heterogeneity, that is, the entire network system is jointly operated by multiple vendors, the entire network system has network equipment manufactured by multiple vendors, and the entire network system uses transmission systems developed by multiple vendors. mechanism, which makes it difficult to achieve joint management and control between different network domains, resulting in insecure and low-efficiency intercommunication among current heterogeneous optical networks

[0004] The development of Path Computation Element (PCE) technology has greatly solved the problem of routing calculation in the network. However, PCE is only a single computing entity, which cannot realize the management and control of inter-domain intercommunication of heterogeneous optical networks.
