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.

현재 이기종 네트워크를 관리하기 위해 다수 관리자가 존재하며, 이런 상황에서 효율적인 네트워크 관리를 위한 새로운 프로토콜로 NETCONF가 제안되었다. 그러나 NETCONF 프로토콜 표준은 제정 이래 지속적인 개선을 거듭해왔지만 여전히 4개의 계층에 몇 가지 문제점을 가지고 있다. 특히 다수 관리자가 존재하는 상황에서는 Operation 계층에서 문제점이 크게 부각된다. 본 논문에서는 이런 문제에 초점을 맞추어 NETCONF 4개 계층 중에 Operation 계층의 연산 효율성과 유연성을 개선하였다. 추가적으로 개선한 연산을 기반하여 장치 설정에 대한 갱신 기법의 비효율성을 개선하였다. 또한 NETCONF 표준 프로토콜에서는 제안하지 못한 Content 계층의 장비 설정 데이터 구조를 생성할 수 있는 표준적인 기법을 제시하였다. NETCONF에 세 가지 개선 기법을 적절하게 적용하고 기존 NETCONF와 제안 기법을 4가지 실험 인자로 비교하는 실험을 수행하였다. 주요 비교 인자는 네트워크 기능 유지 확률, 명령 반응 속도, 제어 패킷의 수, Content 계층에서 데이터 생성 속도라는 4가지 인자이다. 이와 같은 인자를 통해 실험을 수행 한 후 본 논문에서 제안한 기법이 기존 NETCONF 보다 우수함을 실험 결과 분석을 통해서 확인하였다.
