COIT20264 Network Design (HT2, 2019) - Routing and Switching Protocols

This report provides an overview of logical network design, focusing on routing and switching protocols and network security mechanisms. It explains how routing protocols facilitate communication between routers, enabling efficient data transmission across networks, and how switching protocols handle data traffic within a network. The report further discusses the evolution of network architectures, highlighting the shift towards data-centric designs and the integration of packet switching. Additionally, it explores network security, detailing various protection layers, software, hardware, and policies implemented to prevent unauthorized access and ensure data integrity. References are provided for further reading on interdependent network design and the implementation of Open vSwitch.

LOGICAL NETWORK
DESIGN

DISCUSSION OF ROUTING AND SWITCHING PROTOCOLS
Routing protocol identifies how communication is made between routers,
sharing information which enables them for selecting routes among any tow
computer network or nodes.
Routers perform functions of “traffic directing” on internet, one router passes
data packets to another router through network until the destination computer
is reached.

DISCUSSION OF ROUTING AND SWITCHING PROTOCOLS
(CONTINUED)
As data traffic outpaces voice traffic, data-centric architectures will be converted
from carrier networks, changing the course of performance of switch in
transport network.
Packet switching needs to be added to the network and transport network
should be optimized at same time, for meeting the packet switching’s
requirements.

DISCUSSION OF SECURITY MECHANISMS
Network security is used for protecting data transmission within the network. A
networking security system depends on protection layers and have multiple
components which includes security software and networking monitoring along
with hardware components.
All the policies and provisions are included in the network security by network
administrator for preventing and monitoring unauthorized access, modification,
denial or misuse of network-accessible resources and computer network.
