Abstract

Modern network has a complex structure that includes diverse and heterogeneous equipments to cope with multi-purpose functions. For proper administration of networks with complex structures, NETCONF protocol has been proposed. It still, however, has a few unresolved issues with each layer of the protocol. Tackling one of the less attended issues of NETCONF, this article suggests a technique which can efficiently update the configuration data of network equipments when multiple administrators are present. Specifically, for efficient updates of the network equipment configuration, we propose to add a pre-examination of the data dependent to algorithm in 오퍼레이션 layer and modify the data structure for managing XML documents for changing the configurations of network equipments. We have implemented and experimented with our method and confirmed that our approach brought an significant overall performance improvement to NETCONF.

현대의 네트워크는 다목적의 기능을 수행할 수 있도록 이기종 장비들까지를 포함하여 복합적으로 구성된다. 복합적 구성의 네트워크 관리에 적합한 NETCONF가 제안 되었지만 현재까지도 프로토콜의 각 계층에 몇몇 문제가 존재한다. 본 논문에서는 NETCONF가 가지고 있는 문제점 중에서 다른 연구들에서는 많이 다루지 않는 분야인 다수의 관리자가 존재할 때 네트워크 장비 설정 데이터의 갱신을 효율적으로 할 수 있는 기법을 제안한다. 오퍼레이션 계층의 연산에 데이터 종속성 선행 검사를 추가하여 효율적으로 개선하고 네트워크 장비 설정 정보 변경을 위한 XML 문서를 관리할 자료구조도 수정하여 효율정인 장비 설정 갱신이 가능하도록 개선한다. 제안한 기법을 구현하고 실험을 수행한 결과 기존 NETCONF보다 개선 기법을 적용한 NETCONF가 전반적인 성능 향상을 이루었음을 확인하였다.
