Hierarchical Channel Adaptive Packet Scheduling Mechanism for Satellite Networks

1. the art that the invention defined in the claims The invention will here on a hierarchical channel adaptive packet scheduler and method for a satellite communication network. 2. The invention attempts to solve the technical challenges The invention here in the scheduling for the packet to be transmitted to a receiving device in the ACM (Adaptive Coding Modulation) the function is provided a transmitting apparatus [alias ACM Router in a satellite communication network, each receiving apparatus, even if the weather conditions of the area are different from each other in different levels of service, such as the amount of packets to be transmitted and to remain the same each other, fairness between users], the real-time service to each of the receiving device [EF service], best service [bE service] and adaptive service [AF service; in the class to be supported at the same time, in the satellite communication network providing a hierarchical channel adaptive packet scheduler and method that purpose. 3. Resolution of the subject matter of the invention, The present invention at least one of which is in the packet scheduling apparatus of [alias ACM router] The transmission device provided with a (Adaptive Coding Modulation) ACM function, a packet from each other are to be transmitted gatgoseo each service class of different service levels queued in the satellite communication network the multi-class-specific queue; At least one local queue a packet is to be transmitted to each region having different weather conditions are queued; And class-specific queues according to the service level and transmitted by the weather conditions of the packet destination in the transmission destination packet and includes a queue controller for by queuing the packet to the class-specific queues, and local queue provide the region cue transmitted to the receiving device . 4. An important use of the invention, The invention yiyongdoem like DVB-S2 system. DVB-S2, ACM, QoS, packet scheduling, the hierarchical channel adaptive, regional, class specific
