Albany & Pontiac facilitiesare operating with outdatedtechnology. Network uses

cat5 cable along withpatches and hubs.

Corporate & China facilitieshave been modernized withEthernet, switches, hubs andVoIP for phone services.

All facilities operate on astandard star topology.

2



Outdated network equipment and separatetelephone system hinder the Pontiac & Albanyfacilities from effectively communicating with theother locations.

The Ethernet back bone and VoIP processor coupledwith the use of routers and satellites provide a stableenvironment for the Corporate facilities.

3



Increase connection at the Pontiac &Albany facilities.

Upgrade both cabling and switches to allowsupport of VoIP and Ethernet backbone.

Implement Quality of Service (QoS) at the

corporate office to eliminate network congestion.

Install VoIP capabilities to take advantage ofthe lower cost of long distance calling.

Inadequate security documentation at

some locations

No user definition for system access

Insufficient security protocols

No data backup policies in place

8



Develop user authentication protocols

Apply Content filters

Implement System firewall

9



Improve security documentation that meetsfederal, state and business requirements.

Apply user authentication devices to limit accessto the network.

Apply content filters to manage and observe howusers interact with the system.

Implement Firewall to protect from outsideintrusions.

All of the Riordan sites are currentlyutilizing a standard star topology.

The star topology provides a centralconnection point with a hub or switch.

This is ideal for Riordan sites becauseif a cable goes bad then typically it

will only affect one computer rather than the entire network like a bustopology.

12



Most network designers prefer the star topology, because these topologiesmake it simple to add network devices without disruptions to the network.

It is also easy to detect faults and to remove parts as each device has itsown cable.

New stations can be added easily and quickly.

A single cable failure won't bring down the entire network.

The star topology is susceptible to bottlenecking and single-point failurebecause all the nodes rely on a single connection device (the hub).

Total installation cost can be higher because of the larger number ofcables, but prices are constantly becoming more and more competitive.

Reduces network congestion.

Lessens data breaches because itsends the packet to the destinationonly.

Allows each station to utilize fullbandwidth without sharing.

To improve the efficiency of Riordan·s telephoneand data networks Team D suggests:

Update all outdated wiring to Ethernetconnections.

Make use of switches to enhance the operationsof hubs.

Implement documented security measures.
