	An advanced LEO satellite network model based on MPLS-TP (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Advanced Intelligence and Awareness Internet, AIAI 2010, October 23, 2010 - October 25, 2010, Beijing, China 作者: Zhang Y. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 LEO (Low Earth Orbit) satellite networks are capable of providing broadband access to end users in any part of the world. With the characteristics of high-speed movement and rapid dynamic topology of LEO satellites networking has always been one of the key issues in LEO satellite network. MPLS-TP (Multi-Protocol Label Switching-Transport Profile) is an excellent packet transport network (PTN) technology in terrestrial networks which can support multi-service and have perfect function of QoS (Quality of Service) OAM (Operation Administration Maintenance) and survivability. In this paper the characteristics of LEO satellite network and functional architecture of MPLS-TP are introduced. Then an advanced LEO satellite network model based on MPLS-TP (ALSN-M) is proposed which can guarantee a connection-oriented seamless data transmission. Furthermore topology and routing algorithms of proposed LEO satellite network model is analyzed. In the end the paper describes how to setup and remove a LSP (Label Switched Path) and how to maintain an exiting LSP when a handover happens.
