Congestion Control Mechanism in Networks

Lots of unwanted data transmission make the network lead to a problem of congestion. One solution to reduce congestion is to understand the availability of bandwidth, processing power and memory. In real practice it is very difficult to know about the availability and then do the data transmission. One parameter is considered here, that is the available empty space in the memory so that the data loss won't happen which avoid retransmission of data which leads to reduce congestion. Basically when data transmission needs to happen, the available queue length of all the nodes are known to each other. To update the queue length, all the nodes periodically sends the current queue length to all the other nodes. When it's periodic update again it leads to congestion. The proposed algorithm is not going to send periodic update regarding the status of the queue length. When the queue length reaches threshold in any node, that node sends a caution message to all the other nodes that not to send data. So that number of periodic updates will get reduced and by that congestion will be reduced.
