     Network topology is simply a graph.

     The most popular representations of the graph are adjacency list/matrix. Adjacency list node has the following structure (for ex.):

     template <class T>struct Node { T data; std::vector<Node*> childs;};

     If you later want to use graph algorithms, better use adjacency matrix Adjacent matrix

   • Topology Changes in Spanning Tree Protocol (STP)

     Spanning Tree Protocol (STP) is used to prevent loops in the network due to redundant connections between switches in the network. It determines an efficient path from non-root switches to root switches with the help of Bridge Protocol Data Unit (BPDUs).  BPDU carries information regarding topology changes within the network to notify all the switches about the change.

     BPDU

     There are two types of BPDUs that are involved in the topology change mechanism in STP:

     Topology Change Notification (TCN) BPDUs: Non-root switch that encounters topology change in the network transmits TCN BPDU to...

     • Configuration BPDU: Root switch sends configuration BPDUs with set TC (topology change) and TCA (topology change acknowledgment) bit in flags field to notify all the switches about the topology change.
     • Topology Change Notification (TCN) BPDUs: Non-root switch that encounters topology change in the network transmits TCN BPDU to notify root switch about topology change along with regulating the currently used topology by the network.

   • Basic Network Attacks in Computer Network

     Many people rely on the Internet for many of their professional, social and personal activities. But there are also people who attempt to damage our Internet-connected computers, violate our privacy and render inoperable the Internet services. 

     Given the frequency and variety of existing attacks as well as the threat of new and more destructive future attacks, network security has become a central topic in the field of computer networking. 

     How are computer networks vulnerable? What are some of the more prevalent types of attacks today?

     Malware – short for malicious software which is specifically designed to disrupt, damage, or gain authorized access to a computer system. Much of the malware out there today is self-replicating: once it infects one host, from that host it seeks entry into other hosts over the Internet, and from the newly infected hosts, it seeks entry into yet more hosts. In this manner, self-replicating malware can spread exponentially fast. 

     Virus – A malware which requires some form of user’s interaction to infect the user’s device. The classic example is an e-mail attachment containing malicious executable code. If a user receives and opens...
