Write the TCL script and set up a network shown in the figure below. There are 6 nodes, of which 2 and 3 nodes are used as FTP servers and clients, and nodes 4 or 5 are used as the source and purpose of CBR traffic, while nodes 0 and 1 node are used for nodes 0 and 1 nodes. Do forwarding equipment. The link attributes between each node are shown in the figure.

CBR (Constants Bit Rate) is the fixed code rate, which means the constant bit rate.
The meaning of the node 4 at a constant rate of 1Mbps should be sent with 1KB IP package at a constant rate of 1Mbps.
CBR: Constant Bit Rate, fixed transmission rate. Fixed code rate (CBR) is a term used to describe the quality of service quality (QOS). The word corresponding to this word is a variable or variable ratio (VBR). When describing the codec, the CBR encoding refers to the output code rate (or the input code rate of the decoder) of the encoder should be fixed (constant). CBR is very useful when multimedia communication is performed in a limited bandwidth channel, because at this time the highest code rate is limited at this time, and the CBR can better use such channels. However, CBR is not suitable for storage, because CBR will cause enough code rate to encode the complex content part (resulting in a decline in quality), and at the same time, it will waste some code rates in the simple content part.
