Lattice are higher, and single to cover ASON equipment manufacturing costs in million ranks, the whole network forms extensive Intelligent Optical Network using ASON physical equipments
It is costly to carry out performance verification consuming.Meanwhile newly-built ASON network construction periods are too long, are unfavorable for transmitting based on New Generation Optical
The deployment and development of technology and optical-fiber network management and control technology.
Include at present mainly two aspects for the research of the verification method of optical-fiber network performance, one is based on the small of ASON equipment
Scale networking performance is verified；One is carry out large-scale network-estabilishing performance verification by the way of software simulation.Based on ASON equipment
Small-scale networking performance verification method can test performance parameter and deployable of the ASON equipment in localized network, pass through
The workflow of relevant device in a network is checked to the operation of ASON equipment.But in extensive backbone network, business granularity,
The network environment parameters such as type of service, business duration and physical device deployment scenario are different from small scale network, therefore
This kind of method is limited to deployment of the ASON in large-scale network-estabilishing and performance verification reference significance.The packet by the way of software simulation
It includes and certain agreement such as general multiple protocols mark exchange agreement (Generalized Multiprotocol is based on by design
Label Switching, GMPLS), the void of hypertext transfer protocol (Hyper Text Transfer Protocol, HTTP)
Quasi- node simulation ASON equipment or other physical entities simulate relevant information exchange stream using the message format of consensus standard
Journey and mode of operation test its performance parameter in large-scale network-estabilishing, and obtain the relevant information such as handling capacity of network, obstruction
Rate etc., further, it is also possible to by way of mathematical modeling certain innovatory algorithm of simulated implementation, function workflow, compare it
The performance boost obtained with traditional approach.But the method for software simulation, due to all being realized using code, depended software is transported
The factors such as row environment, Code Design method, and due to being realized by Software for Design in agreement, not necessarily have to physics
The scalability of equipment can not verify the actual performance of physical equipment networking.
