網路群播資源管理之集中式架構設計與實現
Architecture Design and Implementation for Centralized Multicast Resource Management over IP/MPLS Network
摘要
本文探討在IP/MPLS網路環境中，提供具備Diffserv QoS品質保證之群播路由服務。為了控制管理群播網路資源有效利用，我們提出集中式管控架構設計，提供跨網域群播路由機制PIM-SM與MSDP整合，群播樹計算、資源保留以及群組管理。現有的群播協定大多屬於分散式控制與演算法，路由器額外負荷重，同時需參與封包傳送。而IP群播路由協定隨著加入群組數量增加，將造成資源分配不足與加入失敗的問題。系統實作在於將群播封包經過QoS分類，加上資源等級之頻寬分割，並採用集中式群播控管機制，將封包傳送功能從群播控制功能中分離，應用MPLS-TE建立點對多點標籤傳送路徑(LSP)。我們將討論與展示系統運作之成果。

In this paper, we present a Diffserv QoS guaranteed multicast service in IP/MPLS network. To achieve efficient multicast resource allocation, we propose the centralized control and management architecture. With collection of network information for centralized multicasting requests, this architecture can perform QoS multicast routing and resource management, and reservation. Due to the scalability and QoS guarantee issue from distributed IP multicasting, the router is required to maintain large amount of multicast forwarding states. Our proposed centralized architecture based on PIM-SM/MSDP multicast routing protocol can support sparse group management and resource management across inter-domain multicast network. Finally, the implemented system operations are demonstrated.
