Development of Update Methods for Configuration Data of NETCONF Protocol considering Multiple Network Administrators

Abstract

Currently a number of managers exist to manage heterogeneous networks, in this situation, the NETCONF protocol for efficient network management has been proposed as a new protocol. However, the standard NETCONF protocol stack continuous improvement since the establishment but in four layers still have some problems. Especially in situations where there are multiple administrators, problems are more highlighted in operation layer. In this paper, we focus on these issues and the Operation layer has improved the efficiency and flexibility of operations among NETCONF four layers. Additionally, for the inefficiency of updates improved the device settings based on improved operation techniques. In addition, standard protocol NETCONF did not proposed content layer data structure and we propose standard technique of content layer that can generate configuration structure of devices. Improved the three techniques are applied appropriately to the NETCONF, the proposed method and the existing NETCONF was performed experiment to compare with experimental four factors. Compare key factor are four kind as maintaining the probability of network function, the reaction performance about command, the number of control packets, performance of data creation in content layer. Such factors after performing the experiment, the proposed method in this paper is superior to the existing NETCONF and there was confirmed by analysis Experimental results. 과 RPC 계층에서 처리 속도를 증가시키는 연구들이 다수 존재하고 있다 [6,7]. 다른 부류의 연구는 네트워크 회선 상에 부가적인 제어 메시지를 감소시키려는 노력과 관련 된 연구들이 있다 [8][9][10].Operation 계층에 포함된 연산 중 <lock> 연산을 수정 하거나 장비 설정과 관련된 메모리를 부분적으로 잠글 수 있게 개선하는 연구들도 있다 [11][12][13][14].지금까지
