Active Intra-ONU Scheduling with Cooperative Prediction Mechanism in EPONs
Dynamic bandwidth allocation in EPONs can be generally separated into inter-ONU scheduling and intra-ONU scheduling. In our previous work, the active intra-ONU scheduling (AS) utilizes multiple queue reports (QRs) in each report message to cooperate with the inter-ONU scheduling and makes the granted bandwidth fully utilized without leaving unused slot remainder (USR). This scheme successfully ...
متن کاملPriority Based Uplink Scheduling Scheme for WiMAX Service Classes
IEEE 802.16 standard supports five different service classes in order to support different needs of the mobile users with different QoS criteria. But, this standard doesn’t specify admission control and scheduling mechanisms and so far many solutions are proposed in the science world. In this paper we propose priority based uplink scheduling scheme for IEEE 802.16 standard that improves the QoS...
متن کاملThe necessity of multicast for IPTV streaming
The IPTV channels require high bandwidth for high clear television programs.. The use of multicast for IPTV service is considered necessary to resolve such problem. IP multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering single stream of data to thousand costumers. Applications that take advantage of multicast include IPTV services, distance learning,...
متن کاملFast retransmission for multicast IPTV
In a IPTV distribution network, broadcast television channels are distributed using multicast stream delivery. Packet loss occuring during transport will impair the displayed video signal and thus reduces the Quality of Experience. Due to the nature of video compression techniques a single lost packet can lead to visual impairments lasting for multiple seconds, so packet loss should be kept to ...
متن کاملAdaptive scheduling mechanism for IPTV over WiMAX IEEE 802.16j networks
A WiMAX technology is a very promising Broadband Wireless Access technology that is able to transmit different service types. This latter can have different constraints such as traffic rate, maximum latency, and tolerated jitter. The IEEE 802.16 Medium Access Control specifies five types of QoS classes: UGS, rtPS, ertPS, nrtPS, and BE. However, the IEEE 802.16 standard does not specify the sche...
