Today, the company utilizes reliable but outdated networking technologies that cannot

be considered as the most efficient already. Therefore, the following technologies were

proposed to be used instead to solve this issue: WiMAX, VoIP, and SIP. The reasoning of

such choice is simple: WiMAX technology is flexible and allows a company to choose the

one, which is needed to cover the particular needs. WiMAX specifications have the range of

working frequency, bandwidth, output power, transmission techniques and access methods of

coding and modulation, the principles of re-use of radio frequencies and other parameters.

Voice over Internet protocol has already become essential for the companies of

different size and scale throughout the world and it is the basic communication instrument for

most of them. It allows transmission of voice signals over the Internet and other IP networks.

This protocol can be used in the offices of Riordan Manufacturing as the main connectivity

tool during the working process. However, since VoIP requires the establishing of the quality

internet connection (a symmetrical 10 Mbps connection), it is preferable to use SIP protocol

between the offices in different regions. It can be used to transfer data via VoIP as well as

PSTN.

The overall network infrastructure of the Riordan Manufacturing is outdated as well.

Bus and ring topologies require establishing of a very reliable and strong connection to assure

interoperability of the business and its continuity. Star topology with application of newest

achievements such as wireless communications within office is an excellent solution instead

of bus topology.

The connections between regional offices should be improved using new

achievements in securing connection because WAN connections need to be protected by the

appropriate means. In addition, backup connection between all key offices must be

established to guarantee that any unexpected events would not shut down the business.

In order to improve network infrastructure and identify any security issues the current

network in Riordan Manufacturing can be present, it is important to conduct traffic analysis.

It is a set of procedures, aimed to deduce information from patterns by intercepting and

examining messages (Alder, Bettati, Callas, & Matthewson, 2010; Mitchell, 2010).

It is easy to conclude what effect data rates have on each part of the Riordan

Manufacturing network. The lower data rates within offices are the less effective the work of

the regional offices is. As the result, the efficiency of the regional branch in overall meaning

will be lower than it could have been using high-speed connection. In addition, low-speed

network do not allow Riordan Manufacturing implementing such new tools as

videoconferencing, facilitated online communication, etc. and it can influence the quality of

the work process rather substantially (Alder, Bettati, Callas, & Matthewson, 2010; Mitchell,

2010).

Satellite connections between different regions should have high quality and assure

high data rates because slow process of strategic data transmission could influence decision-

making process. It means that inappropriately slow transmission of some part of the

managerial or financial data between regional branches could lead to the process of stalling

within the company and loss of positions in the future. Therefore, modern means of

communication must assure the highest data rates possible in order to facilitate and support

decision-making processes within Riordan Manufacturing.

Therefore, the company needs to have the appropriate network topologies and the

necessary hardware (Cisco.com, 2008). It is necessary to assure that all computers have

access to the networks resources via switches and segments’ switches are connected together

via routers. It is the only possible best strategy to ensure the availability of network access

within Riordan Manufacturing. Thus, the company needs to rebuild its network to comply

with modern needs (Cisco.com, 2008).
