Dynamic Control Frames in Reservation-Based Packet Scheduling for Single-Hop WDM Networks

In reservation-based packet scheduling algorithms for single-hop WDM networks, one of the wavelengths is used as a control channel which is shared by all of the nodes for transmitting reservation information. Time on the control channel is divided into control frames of fixed length. Each of the control frames is further divided into a number of control slots. Before transmitting a data packet, a node sends a control packet in a control slot to inform all other nodes of its intention to send a data packet. The data packet can then be scheduled for transmission. Each of the nodes in the system is assigned a dedicated control slot. Free control slots in the control frames cannot be used by other nodes. The control packets generated by those nodes that have more data packets to send must be transmitted in the next or later control frames although there are a number of free control slots. The result of delaying the transmissions of control packets is increased packet delays. This effect ...
