Task 1
Requirement Gathering
The requirement of the call centre should be identified for the development of the network
solution and the Netsim simulator should be used for the development of the network solution. A
qualitative and quantitative analysis is made on the requirement of the users and the software
needs for the development of the network solution. A meeting must be arranged with the
stakeholders and the quality of the information depends on the success of the network. The creation
of the questionnaires also helps in identification of the needs and it should be shared with the users
associated with the development of the call centre network. The number of users and the floor plan
of the building of the call centre should be analysed for the development of the network framework.
The number of vlans and the Pc required for the connection with the department should be
identified and separate vlan should be created for each of the floor for increasing the efficiency of
the network.
Technique used for collecting requirements
There are different techniques used for the analysis of the requirement such as:
Prototyping – A prototype of the network is created and is shared with the group of users for
identification of the changes in the network plan and develop the final network according to the
needs of the users.
Brainstorming – New ideas and technologies should be identified for the development of the
network. The risk associated with the network should also be analysed for the implementation of
the security features in the network.
Survey – A survey should be made on the current network infrastructure and the upgrades that
should be implemented and the constraints acting on the network should be identified. The needs
for the development of the framework should also be justified and migration to different technology
should also be identified for the preparation of the network solution.
The backup and the recovery time of the network should be minimum and the network
boundaries should also be identified for identification of the hardware needs for the development of
the network solution. The selection of the network protocol is also important for the reduction of
the errors in the configuration and delivering a fully working and secure network solution for the call
centre. The use of redundant link and the VLANs improves the performance of the network and
reduces the effort of management of the network.

Figure 1: Network Solution for the Call Centre
Network Design Justification
The device used for the configuration of the call centre network is Cisco 2811 series router
and it is fast Ethernet interface is subdivided into two parts for the two VLAN created for the
network. For the expansion of the network new router can be connected with the router serial
interface and both the router should be configured with IP routing for enabling transferring of data
packets from one router to another interface. The Pc are configured with the DHCP settings such
that the PC connected in each of the floor of the building can be assigned with an IP address
automatically. The network plan is created for meeting the growing needs of the organization for the
upcoming five years and for that the latest technology are used such that the network settings does
not becomes obsolete. The use of the latest technology helps in development of an Ipv6 ready
network solution and the interface can be configured with Ipv6 such that it can communicate with
the Ipv6 network for sending and receiving of data packets from the network configured with Ipv6
address. The configuration of the two different VLAN in the network helps in dividing the network

into two different communication channel and reduce the congestion in the network and reducing
the response time of the network. The backup router is deployed in the network that can be used if
the core router fails and increases the network uptime.

Performance Metrics
For the analysis of the performance of the network different network monitoring tool such
as Wireshark, PRTG network monitoring software can be installed in the server for the analysis of the
traffic flow of the network between the different hosts connected in the network. The decision of
the network helps in increasing the performance of the network. The use of the network monitoring
tool helps in generating a notification and alert for the network if any intruder tries to access the
network illegally. The illegal attempt should be monitored and stored in the network for recording
the current activity of the users connected in the network. The performance metrics consists of the
time, cost, resource, scope, quality and the different actions included for the development of the
network solution. The performance metrics helps in identification of the internal performance of the
network and quality of the network by identification of the outputs. The output obtained from the
network is compared with the desired output for the identification of the network performance.

The ping test is used for analysis of the time required for accessing different vlan and it is
found that for the same vlan the average response time is 62 ms and for connecting with the
different vlan the average response time is 65ms. There are no jitter in the network since different
communication channel are used for the network and it reduces congestion and increases the
efficiency of the network.
