Network animator is the considered as the animator tool in the process of network trace and packet trace in real time as the graphical representation. On the other hand, the network simulator is denoted as the open source tool to simulate both the wired and wireless computer networks. Nam and Ns are capable to be utilized together for the creation of simulated network and to analyze the process. Additionally, we have provided the instructions for the installation process in the following.
Install Instructions
- cd to your ns-allinone
- remove the nam-1.0a11 directory (rm -rf nam-1.0a11)
- expand the ext-nam-1.0a11.tar.gz archive (tar xzvf ext-nam-1.0a11.tar.gz)
- cd nam-1.0a11
- build the extended nam editor (./configure; make clean; make)
The above mentioned steps are about the process of starting the source distribution for the installation. In addition, we have enlisted the steps to start the binary distribution process in the following.
- expand the ext-nam-1.0a11.gz file (gunzip ext-nam-1.0a11.gz);
- put the nam binary in your path
Packets in Nam
While a trace line refer as the packet then the event type may be + (enqueue), – (dequeue), r (receive), d (drop) and h (hop). In addition we have highlighted all the process in the following.
- -n <sequence number>
- It is the provision of the packet sequence number
- -P <packet type>
- It provides an ASCII string specifying a comma separated list of packet types and some of the values are highlighted below
- SRM
- SRM data packet
- NACK
- Generic negative acknowledgement
- ACK
- Generic acknowledgement
- TCP
- The tcp data packet
- -p <pkt-type> is the descriptive name of the type of packet seen
- -d <destination id> is the destination node
- -e <extent> is the size (in bytes) of the packet
- -s <source id> is the originating node
- -t <time> is the time the event occurred
- – Leave queue
- The packet left the queue from <source id> to <destination id>
- + Enter queue
- The packet entered the queue from <source id> to <destination id>
- D Drop
- The packet was dropped from the queue or link from <source id> to <destination id>. Drop here doesn’t distinguish between dropping from queue or link and this is decided by the drop time
- R Receive
- The packet finished transmission and started to be received at the destination
- h Hop
- The packet started to be transmitted on the link from <source id> to <destination id> and is forwarded to the next hop
- type -t time -e extent -s source id -d destination id -c conv -i id
Until now, we have provided the fundamental guidance and required steps related to Nam in Ns2. For more details on simulation tools, software, protocols, algorithms, research techniques and etc. the research scholars can contact us and for more reference you guys can take a look into our website.
