Title: Method of scheduling for guaranteeing various kinds of QoS in Ethernet-PON
Inventor: KIM MYEONG HUN
IPC: H04L47/80
Filed: 2002-12-12
Abstract: PURPOSE: A QoS(Quality of Service) guaranteeing method in Ethernet optical network is provided to guarantee various QoS restriction conditions required by various kinds of multimedia application services. CONSTITUTION: A buffer manager of a system of an OLT checks whether buffers overflow at every moment. If the buffers overflow and thus newly arrived packets are lost, it is determined whether a loss rate measured on a real time basis is lower than a permissible loss rate in a corresponding class. If the loss rate measured on a real time basis is lower than the permissible loss rate in a corresponding class, the system maintains the current state. If even one of QoS restriction conditions applied to each class queue is violated, a scheduling algorithm operates to allocate a new band. The number of received packets are counted, and if the number of packets exceeds a periodical number and QoS numerical values experienced in each class exceed permissible numerical values with respect to delay, jitter and loss allocated to each class, the scheduling algorithm operates to allocate a new band.
