·     High level of redundancy is expected in network design to eliminate single point of failures and traffic bottle necks.

·     Sales and Marketing Team need to access Network resources using WIFI connectivity.

·     Proper methods for networking monitoring and troubleshooting need to be established.

·     All possible network security mechanisms should be implemented.

·             Discuss the importance and impact of network topologies and network protocol suites while comparing the main network topologies and network protocol suites that are used in network design using examples. Recommend suitable network topologies and network protocol suites for above scenario and justify your answer with valid points.

Answer 1

Network topology is the the description of the arrangement of nodes for example switches and routers. This topology have numerous impacts for example error or fault detection is made easy using network topologies. This topology allows for dynamic network routing, meaning traffic has multiple paths it can travel across. network topology helps us understand two crucial things. Network topology allows us to understand the different elements of our network and where they connect and they show us how they interact and what we expect from their performance. examples of this topologies are start topology, bus topology, ring topology, mesh topology and hybrid technology. Network protocols allows connected devices to communicate with each other. Protocols are very important since they are the reason users in various department communicate internally or externally. Protocol suite is a set of communications protocols used in the internet and similar computer networks. this suite defines end-to-end data handling methods for everything from packetizing, addressing and routing to receiving. Star topology is the most preferred since each network component is physically connected to a central node such as a router or switch. When the central node receives a packet from a connecting node, it can pass the packet on to other nodes in the network. Internet protocol and Transmission Control Protocol suite. IP is used for broadcasting and transmitting data over the Internet while TCP enables two hosts to establish a connection and exchange streams of data and guarantees delivery of data and guarantees that packets will be delivered in the same order in which they were sent.
