NETW206: Introduction to Switching
Submitted to:
Professor: Name of your professor
Date: Current date
As per the requirement, we are going to use the Cisco 4300 Video Surveillance model camera
in here. So we have to have a good reliable switching architecture for getting the maximum
throughput from these cameras. Otherwise they are acting as just ordinary video camera. When
we are speaking about the switching architecture of this project, first of all we have to fulfill some
major requirements. They are,
1. Must comply with the Cisco hierarchical design model;
2. Must provide physical, as well as logical, redundancy;
3. Must integrate 1Gb uplinks;
4. Must segment camera IP traffic from the existing network for security reasons;
5. Must support a minimum of 150 cameras;
6. Must utilize PoE for cameras to avoid the use of power bricks or power injectors;
7. Must provide sufficient bandwidth for full HD support; and
8. Must minimize rack space.

SUPPORT FOR HIGH-DEFINITION IP CAMERAS 2
First of all we’ll discuss about the Cisco hierarchical design model. The Cisco hierarchical
design model is a three-tiered or layered network model that is used to design and engineer
data communication networks. These three tires are,
Access layer - The access layer interfaces with end devices, such as PCs, printers, and
IP phones, to provide access to the rest of the network. The main purpose of the access
layer is to provide a means of connecting devices to the network and controlling which
devices are allowed to communicate on the network.
Distribution layer - The distribution layer aggregates the data received from the access
layer switches before it is transmitted to the core layer for routing to its final destination.
The distribution layer controls the flow of network traffic using policies and delineates
broadcast domains by performing routing functions between virtual LANs (VLANs)
defined at the access layer. VLANs allow you to segment the traffic on a switch into
separate subnetworks.
Core layer - The core layer of the hierarchical design is the high-speed backbone of the
internetwork. The core layer is critical for interconnectivity between distribution layer
devices, so it is important for the core to be highly available and redundant.
