The Study of RED Algorithm Used Multicast Router Based Buffer Management

摘要

The CBT method that is a dual shared tree enables both a transmitter and a recipient to exchange data through the shortest route to the center core. This method is used to solve the expansion problem of multicast by using a core. However, the current Multimedia Routing Method that involves a packet switching of Best-Effort method tries to transmit only single packet; thus, it causes congestion of data around a core and RP. As for a solution of this problem, the thesis suggests the RED algorithm applied Anycast method. The Anycast Protocol is a way to transfer a packet to an optimal server or a host that is able to redistribute the packet to the most adjacent router or Anycast group members who have Anycast address. Likewise, Anycast redistributes a packet of a core, then again redistributes it to any adjacent router and transmits the packet to an optimal host. In order to redistribute a packet of Core, RED Algorithm is adopted to disperse traffic congestion around the core.
