홈네트워크 사업자는 빠르게 확대 되는 시장 환경에 맞춰 확장성, 신뢰성, 유연성, 저비용의 구조로 홈네트워크 서비스를 제공하는 것에 대해 많은 고민을 하고 있다. 기존 클라이언트-서버 방식은 홈네트워크를 서비스하는데 있어 복잡성, 고비용 등 다양한 문제가 존재한다. 본 논문에서는 이러한 문제를 해결하기 위한 P2P-SIP(Peer to peer - Session Initiation Protocol) 구조를 제안한다. 분산된 자원의 접근을 지원하는 P2P(Peer to peer) 통신 방식의 단말에서 기존의 SIP(Session Initiation Protocol)기반 네트워크 장치들이 가지던 기능을 제공한다. 또한 단말의 이동성을 고려한 네트워크 기반의 PMIPv6(Proxy Mobile IPv6)기술을 적용하여 이동성 관리에 따른 지연시간을 최소화한다. 특히 제안하는 P2P-SIP 구조는 평면 구조에 비해 지역 내 다양한 홈네트워크 간의 뛰어난 확장성과 유지비용을 절감하는 매우 효율적인 구조임을 보여줬다.
Abstract
Home network providers have many worries about providing home network services with an expandable, reliable, flexible and low-cost structure according to the expanding market environment. The existing client-server system has various problems such as complexity and high costs in providing home network services. In this paper we propose the P2P-SIP structure. P2P communication terminal supporting access of distributed resources provides functions which the existing SIP-based network devices have. Because diverse terminals in a home network access through networks, also, partitioning network domains with home gateways to manage, and applying the network-based PMIPv6(Proxy Mobile IPv6) technology considering mobility of terminals would help to have a more efficient home network structure. Especially, the proposed P2P-SIP structure proves itself as a very efficient structure to have an outstanding expandability among different home networks in a region, and to reduce maintenance costs.
