The History Of The Cost Breakdown

Published Date: 02 Nov 2017

The proposed networks between the new and existing campus premises and also within the premises will require new hardware, software, services and human resources to implement, administer and maintain. The proposed network design for this project was developed taking the cost of the project and future expansions to consideration. Although equipment and installation costs can be considerably low, the consistency of these tasks and the hardware used will determine the maintenance and administration costs in the long run.

The following section attempts to cover the costs and expenses of hardware and services required for the proposed network. Labour costs for the project have not been included in this cost breakdown. The following hardware components were specially chosen for their cost efficiency and flexibility. Some components are not relatively the "minimum requirements" for the job but these were chosen mainly considering possible future extensions and geographic growth.

This section also contains a brief technical description on each component which would represent as to why these were chosen for the specific job. The cost breakdown and prices are subject to minor changes due to the ever changing market and technology industry. All specified device prices were obtained through Barclays, Sri Lanka by studying and requesting information on such purchases, considering stock and retail purchases.

Wi-Fi Router

The proposed device in this instance is Cisco Aironet 1140 Wireless Access Point. These devices are used in every floor of the new campus premises to offer wireless connectivity to students, staff and authorized visitors. This primary device works as an access point and can be configured to work as a router where needed.

This device can be considered way over the minimum requirements for this design but has been proposed due to its increased throughput and future extensions where wider coverage might be facilitated with these existing high-end devices.

L2 Switch (24 Port)

The Cisco SLM2024 24-Port Gigabit Smart Switch will be used for all L2 switch (24 ports) requirements throughout the network.

This piece of hardware has an easy-to-use web browser interface which will make installation quick and effortless. The high-speed connectivity of the device will support bandwidth-intensive applications which will be constantly run from within the campus network.

The Wi-Fi router is also capable of keeping potential intruders out of the network using its switch port level security measures.

This device is also capable of offering basic Quality of Service (QoS) technology which will help ensure a consistent network experience to all students and staff. This will include support for the fluid use of networked applications, including voice, video, and data storage.

The device is shipped by the manufacturer with a limited lifetime warranty and the manufacturer offers local technical assistance and support as well.

L2 Switch (8 Port)

The Cisco SPS208G 8-Port 10/100 + 2-Port Gigabit SP Switch will be used for the 8 port L2 switch needs within the proposed network.

This piece of networking hardware is categorized as a cost-effective access or Customer Premises Equipment (CPE) switch.

It features comprehensive security features for robust multitenant separation and is optimized for triple-play (VoIP, video, and data) services as well.

This component also boasts service provider provisioning and management features to enhance maintenance and administration capabilities.

Features at a Glance

Eight 10/100 switched RJ-45 ports that deliver up to 200 Mbps of throughput per port

One 10/100/1000 switched RJ-45 port

One mini Gigabit Interface Converter (mini-GBIC) port delivering up to 1000 Mbps

5.6 Gbps nonblocking, store-and-forward switching mechanism

L3 Switch

The preferred device for a L3 switch is the Cisco Catalyst 4908G L3 Switch. It provides non-blocking routing and switching for IP, IPX, and IP multicast. The product also offers wire-speed Layer 2 switching for non-routable protocols such as NetBIOS and DECnet local-area transport (LAT). This capability allows network administrators to patch-up and upgrade their multiprotocol backbones with the Catalyst 4908G-L3 without having to build parallel networks, as is often required with IP-only switches. This is quite a useful option and might be very useful in future extensions of the campus network.

This new switch provides standard performance that is needed for mid-sized campus backbones with just the right port density and capacity. It is very suitable for connecting together multiprotocol traffic from multiple wiring closets or other switches.

Features at a Glance

Eight ports of 1000BaseX Gigabit Ethernet with gigabit interface converter (GBIC) support, all ports with Layer Three switching capability at wire speed

High Performance—over 11 Mpps Layer Three Switching and Routing of IP, IPX, and IP Multicast

22 Gbps non-blocking switch fabric

High Performance CPU with Cisco IOS® system software

Quality of Service (QoS)—multiple queues with Weighted Round Robin (WRR) scheduling

Comprehensive management tools based on standard CiscoWorks2000 applications

Access List Support on all ports

Wiring and Cables

Cabling is one of the most important aspects in a network design but is sometimes overlooked. In this design, the approximate length requirements for the wiring have been increased considering future additions to the network within the new campus premises. Additional wiring is a must in any modern network design, if it is to facilitate the addition of devices and hosts in the future.

The CAT 5 cable will be used for all wiring purposes throughout the campus premises. This level of consistency will help future maintenance and administration of the network and facilitate effortless upgrades and integrations.

Sri Lanka Telecom (ISP) ADSL Line (16 Mbps)

The two SLT ADSL lines will be treated as the primary internet access lines for the entire campus premises. The high-speed requirement is mainly due to the large number of students that will be constantly accessing the internet through workstations located in the labs and through a variety of personal wireless devices. It is important that higher-speeds are offered to keep the quality of service in the expected level.

Dialog (ISP) ADSL Line (8 Mbps)

One of these two Dialog ADSL broadband lines will be used solely by the Research Lab for its purposes. The other connection will be used as the primary backup for the entire campus premises in case of primary line outage. The lower bandwidth and usage statistics have been considered as a cost cutting measure. This is due to the fact that, this backup network will not be used as heavily as the primary lines in normal circumstances.
