NET IP NETWORK DESIGN FOR Itelco

This study develops a new network design for ITelco, an information technology (IT) company. The developer of the network design is the Network Planning and Engineering Department of Information Services Technology, Inc. (ISTI).

ITelco Organizational Structure Relevant to Network Design

ITelco has network requirements for approximately 50,000 users (employees and clients). The distribution of users covers six North American locations. Table 1 (below on this page) documents the geographic distribution of ITelco network users. Figure 1 (on the following page) illustrates the geographic distribution of ITelco network users.

Chart 1 · Geographic Distribution of Users of ITelco Network

The geographic distribution of user clusters indicates the need for developing the company's new network as a wide area network (WAN). The presence of three user clusters in the Ottawa area allows the consideration of the desirability of a subsidiary network for the Ottawa region, as 30,000 (60 percent) of the users of the c

Rather than a code, the value "8" represents the size of a byte in bits in the equation (Ramaswamy, 1999). The code for bandwidth is "BW". The determination of bandwidth requirements requires solving the equation for both outbound traffic and inbound traffic. The full equation for estimating bandwidth requirements is as follows (Ramaswamy, 1999): BW = 8 x N x K x M / (K x P + T) BW = X bits/second Conversion of the bits/second value to 1,000 (K) bits / second yield a value that is most usable in bandwidth requirements analysis. Thus, BW = XK bits/second Where XK bit/second = (bits/sec) / 1,000 The determination of estimated bandwidth requirements for the ITelco WAN relied on the use of assumptions for some values and on company estimates for other values. The values used in the bandwidth estimations, together with data sources (assumptions or company estimates) were as follows: 1. Number of active users (maximum): a. Corporate Headquarters (Toronto): 5,000 (source: company estimate). b. Sales & Marketing (New York): 10,000 (source: company estimate). c. R&D LOB #1 (Ottawa): 10,000 (source: company estimate). d. R&D LOB #2 (Ottawa): 10,000 (source: company estimate). e. R&D LOB #3 (Ottawa): 10,000 (source
