Practice TasksAssignment4 1.Create a network consisting of two nodes: PC1 and PC2. Node PC1 should generate andsend packets (with incremental packet IDs i.e., Pk1, Pk2, Pk3,...) to PC2 node. At nodePC2, it should send back numbered acknowledgement (i.e., Ack1, Ack2, Ack3,...)messages to node PC1. Hint: To generate a message/packet having different sequencenumber each time, following code snippet will be helpful:msgname [20];sprintf (msgname, "tic-%d", ++seq);CMessage *msg = new cMessage (msgname);charAssignment5 2.Create a network consisting of three nodes i.e., Server, PC1, and PC2 (Topology shownin Figure 4.15).

Create a network consisting of two nodes: PC1 and PC2. Node PC1 should generate andsend packets (with incremental packet IDs i.e., Pk1, Pk2, Pk3,…) to PC2 node. At nodePC2, it should send back numbered acknowledgement (i.e., Ack1, Ack2, Ack3,…)messages to node PC1. Hint: To generate a message/packet having different sequencenumber each time, following code snippet will be helpful:
char msgname[20];
