Advanced Network Design: Analysis, Configuration for Call Center

This report details the development of a network solution for a 24/7 call center, emphasizing continuous availability and minimal data packet delivery time. The report includes a requirement analysis, identifying necessary network framework components and suitable protocols for router and switch configurations. Requirement gathering techniques involved brainstorming, questionnaires, and stakeholder meetings to assess user needs and building floor plans. The network design incorporates six layer 3 switches, layer 2 switches for management, Cisco 2811 series routers, and Cisco 7960 VOIP phones. The network is segmented into subnets based on the organization's floor plan to enhance security and efficiency. Security measures include a SYSlog server for monitoring network traffic. VLANs are implemented for data and voice traffic to improve performance and reduce collisions. The design aims to meet the call center's requirements for the next five years, with scalability for future growth. Redundant links are incorporated to ensure continuous connectivity, and tools like PRTG network monitor are suggested for performance analysis. The report concludes that by identifying the call center's requirements, errors in the network solution can be minimized, leading to an effective and available network.

Introduction
The report is prepared for a 24/7 call centre for the development of the network solution for
the organization such that the network device are available all the time and it is able to deliver the
data packet to the destination taking minimum time. For the development of the report a
requirement analysis is done on the needs for the development of the network framework. The
protocols that should be used for the configuration of the network is identified for the configuration
of the routers and the switches used for the development of the network solution. Different
techniques are used for gathering the requirement from the user such as brainstorming, using set of
questionnaires and arrangement of stakeholder meetings. The number of user and the floor plan of
the building of the call centre should be evaluated for the development of the network.
Task 1
Requirement Gathering
The main requirement of the organization is to develop a network solution for a 24/7 call
centre that requires different hardware and software for the development of the network. A
research has been done on the latest technology that can be applied in the network for the
development of the network infrastructure. The success of the network solution depends on the
quality of information gathered form the different sources. Questionnaires should be created and
distributed to the users for the identification of the requirement of the network solution. An
appropriate cabling plan should be used for interconnecting the different departments and
identification of the needs of the upgrades of the current network devices installed in different
location of the organization.
Technique used for collecting requirements
A quantitative and qualitative analysis should be used for the identification of the requirement
for the development of the network solution for the Call Centre. For gathering the requirement of
the network the data is gathered from the users, applications and the devices. Stakeholder meetings
should be arranged for the identification of the needs of the software and the hardware required for
the development of the network solution. The constraints identified from the existing network and
the expected growth of the network should be identified for creating an interoperability within the
existing network. The services that are needed for the development of the network infrastructure
should be identified for designing the architecture of the network. The existing network architecture
should also be analysed for incorporating it with the existing network. The components that are
needed to be identified are listed below:

 Upgrades of the systems
 Migration from one technology to another
 Use of network protocol for upgrading the network infrastructure.
It is also important to identify the dependency of the user and constraint of the existing network
such as the change in the size and the scope of the network framework. The boundaries of the LAN
or WAN should also be defined. The number of users using the system and the list of application and
software installed in the system should be listed for the development of the network infrastructure
and dividing the network into smaller subnets for increasing the security of the network.

Network Design Justification
The network is designed with 6 layer 3 switch for the management of the distribution of the
data packets in the network. In the management department two layer 2 switches are used for
connecting the hosts with the network. Two routers are installed in two different floors of the
building and cisco 2811 series router is used for each of the floors. Cisco 7960 VOIP phone is used for
the call center for making call using the internet and reach the client. The Phones are connected
with the laptops for reducing the cabling cost and increasing the accessibility of the system. The
network is divided into different subnet following the floor plan of the organization and reduce the
generation of broadcast messages for increasing the efficiency of the network solution. The current

network designed for the call centre can meet the requirement of the next five years and more
devices can be added in the network for handling the growth of the organization in future. For
increasing the security of the network the SYSlog server is used and it monitors the current flow of
the data traffic in the network.
