With the continuous progress of science and technology and the rapid development of the Internet, higher requirements have been put forward for network performance. EONs (Elastic Optical Networks) is proposed as an optical network with high reliability, high efficiency and high survivability. Although there have been many researches on EONs and various performance indexes, it is still a problem how to evaluate the comprehensive ability of optical networks comprehensively. This paper designs a network design scheme evaluation model based on AHP (Analytic Hierarchy Process) and business priority. According to the evaluation results, different protection schemes are adjusted, which provides valuable reference for the construction of network planning scheme. The basic performance index is obtained according to the scheme and network planning algorithm, and the survival performance index is obtained according to the protection algorithm. AHP was used to establish the hierarchical structure model for these two categories, paired comparison matrix was constructed through the comparison of two performance indicators, consistency test was conducted, and the final weight was calculated. Finally, according to the weight of the total order of the weighted hierarchical weighted calculation, the final decision basis. Multiply the weight of the decision by 100 to get a percentage score. Based on the score, it can determine whether the solution is suitable, and then adjust the business priority and network design solution, as well as provide effective reference for network planning.
