packets in a queue for transmission. ERT-805 is provides four different types of queue that is FIFO (default in all router), WFQ (Weighed fair queuing), priority queuing and custom queuing.

6.4.1 FIFO- First IN First Out

The traffic for FIFO is transmitted in the order received, without regard bandwidth consumption. In FIFO all packets is treated equally. Packets are sent out an interface in the order. This method is default for all router interfaces.

6.4.2 WFQ – Weighted Fair Queuing

WFQ is an automated method that provides fair bandwidth allocation to all network traffic. WFQ breaks up the train of packets within a conversation to ensure that bandwidth is shared fairly between individual conversations and that low-volume traffic is transferred in a timely fashion
