What is the function of the network relay device?
The main function of relay equipment is to expand the transmission distance and transmit the signal along the depth!
Each segment can use different communication rates.(5) reliability is improved. When a network fails, it usually affects individual segments only.(6) performance is improved.
(1) the filter traffic repeater receives packets from a subnet which is forwarded only if the message is sent to another subnet attached to the repeater, otherwise it is not forwarded.(2) to enlarge the communication distance, but the cost is to increase some storage and forwarding delay.(3) the maximum number of nodes is increased.
