Riordan Manufacturing WAN Analysis
INTRODUCTION
Riordan Manufacturing is a large plastics manufacturer with 550
employees in four locations. The locations Riordan operates are
San Jose, California, Albany, GA, Pontiac, Michigan, and
Hangzhou, China. The San Jose, California facility is the
corporate office and is connected to the other facilities through
a Wide Area Network (WAN). Each location has a different
telephone and data network. According to Moore’s law, the rate
of technology advancement doubles every 24 months.

2. Companies have difficult tasks with staying current with
advancing WAN technology. Within the past several years,
platform as a service (PaaS) and infrastructure as a service
(IaaS) have emerged as a leading local area network (LAN) and
WAN infrastructure option. Riordan has an existing WAN
infrastructure that is outdated and expensive to maintain. Before
Riordan can upgrade the existing WAN to the most current
technology, Riordan needs understand their business goals and
requirements, and evaluate the existing WAN for strengthens
and weakness. Understanding the business goals and
requirements will have a direct impact on the WAN technology
that will be implemented.
Section II
Riordan is in the process of relocating their Hangzhou,
China office to the Shanghai port area. The relocation of the
office will result in significant cost savings, and will provide
their operations with a more substantial urban infrastructure and
will put them into a better position to market and ship their
Chinese products throughout Europe and Asia. Currently they
are spending over $100,000 on travel for training on the new
intergraded systems; we can develop Riordan a distance
learning solution so that we can provide effective training
through teleconferencing. A new network infrastructure
including workstations will have to be designed, purchased,
installed and tested.
Their IT network is very slow and outdated, currently they
are using outdate software and need to update to Windows 8
based environment and Microsoft upgrades to Office 10. The
workstations need to be updated the RAM and hard drive space
is inadequate. Instead of using the 8 separate printers I would
add a print server and add two printers to the network so that all
users can print from those two. We need to cut down on the
number of switches and streamline the network, by installing a
Cisco ASR 1006 with serial, Ethernet and Fiber modules as the
core router and upgrading the switch to a Cisco 3750X 48 port
switch you will be able to connect all servers, routers, VoIP

3. phones, and workstations from one switch. The satellite
connection and the T3 will be connected directly to the ASR
1006. All switches, routers and servers will either use a Cisco
SFP-10G-LH for fiber connection and Cisco GLC-T 1000BASE-
T SFP for Ethernet connections.
The network is currently using a 100baseT backbone; we
would like to upgrade this to a 1000baseT backbone utilizing a
fiber optic or 10G Ethernet backbone. By upgrading the 35
VoIP phones to Cisco IP 9951 VoIP conference phones that can
be used for individual effective training for long distances.
The WIN, WIN Exchange and UNIX server and data storage
devices are outdated and should be updated to Cisco MCS 7835
Unified Call manager with Publisher/TFTP and
Subscriber/Conference will provide voice and Email. The Cisco
3545 ISDN can be used for video conference. The NAS is
inadequate and has no redundancy by upgrading to NETAP
DS2246 with 72 600GB hard drives will be used for data
storage. The VoIP router will no longer be needed with the
installation of the MCS 7835. A standalone APC Symmetric
uninterruptible power supply (UPS) will provide 3 hours of
power in case of loss of power.
In the development of their system’s architecture, its initial step
would be to provide a definition for the process of
communicating information to other places using their new
system. The network that Riordan Manufacturing has can
facilitate communication and transmission of information to
every location that they have.
Riordan Manufacturing has four physical locations that are
currently interconnected by a WAN network, the Wan
connection between the corporate headquarters office in San
Jose and the China facility is done by a satellite link using a
KA band satellite with a 51.8 MBS data transfer rate and AES
end to end transmission. Riordan Manufacturing's corporate
headquarters is divided into four sections using a 100 base T
Ethernet connection. The Administrator section handles the
main operational functions it gives the number of employees in

4. specific areas, a description of the various computers used and
their individual locations and 36 VOIP telephones. The
Research and Developments section has a 1000baseF network
and is MAC based there are 15 employees each with computers;
this section includes 3 high-end color printers and a plotter. The
1000baseF network is connected to the corporate LAN through a
switch. The next section is for servers, the servers that Riordan
Manufacturing are using are IBM and include a WIN server, a
WIN Exchange server, and a UNIX server, which hosts the
corporate SAP ERP the WIN servers are IBM HS20 blade
servers and the main UNIX server is an IBM p series. The last
section is the communications section which has two main parts
the first is the data link to the Satellite base station through a
switch and a VOIP router to connect the two facilities with
voice. The satellite operates in Ks band @ 51.8mb and is setup
to handle an OC1 data rate with end-to-end encryption. The
second part of communications is a router to provide a T3
connection through a firewall to the outside network.
Riordan Manufacturing – Albany, GA
The Albany Georgia location network uses 20 office computers
for its administration operations, the Albany location server is
an HP BL460P blade server, which does the local printing, file
exchanges, and interfaces back to the home office. A local NAS
system does a local data backup and a link to the
router/firewall provides the T2 connection to the outside
network. Internally the factory floor is connected to the main
LAN through a 24 port Linksys EF2H24 Cisco switch.
Riordan Manufacturing – Pontiac MI
The Pontiac Michigan network uses 45 office computers for its
administration operations, the Pontiac Michigan location server
is an HP BL460P blade server, which does the local printing,
file exchanges, and interfaces back to the home office. A local
NAS system does a local data backup and a link to the
router/firewall provides the T2 connection to the outside
network. Internally the factory floor is connected to the main
LAN through a 24 port Linksys EF2H24 Cisco switch. A 5KVA

5. UPS is used for backup power.
The Shanghai China Headquarters is also divided into sections,
the Administrator section handles the main operational
functions it gives the number of employees in specific areas, a
description of the various computers used and their individual
locations and 35 VOIP telephones. The Research and
Developments section has a 1000baseF network and is MAC
based there are 15 employees each with computers; this section
includes 3 high-end color printers and a plotter. The 1000baseF
network is connected to the corporate LAN through a switch.
The servers at the Shanghai China headquarters are all IBM and
include a WIN server, a WIN Exchange server, and a UNIX
server, which hosts the corporate SAP ERP the WIN servers are
IBM HS20 blade servers and the main UNIX server is an IBM p
series. A 5KVA UPS is used to provide backup power for the
server room.
Riordan Manufacturing’s current interconnected WAN network
is Ethernet based and is using Cat5E cabling with RJ45
connectors throughout all of its facilities. Each computer or
device is connected with Cat5E cabling and RJ45 connectors to
either a Cisco 2950 switch a local gateway or to a Linksys
EF2H24 24 port hub.
When determining how a network will function, deciding on
both the logical and physical topology is imperative. Depending
on which logical topology is decided on, the method in which
data is transmitted may vary. According to Rouse, 2013, it
cannot be assumed that a physical topology dictates what logic
the network will adhere to. It is entirely possible to have
various physical network topologies all employing the same
logic. This is important to understand as a network is developed
and implemented for enhancing communication flow. Failure to
understand concepts imperative to the foundation of network
can severely hinder a networks performance.
Riordan Manufacturing wants to enhance communication
efforts throughout the organization and by doing so, increase
productivity. There are several different logical network

6. topologies that could benefit their demands. When developing
the network there are several key areas that must be identified
for Local Area Networks. First and foremost is scalability.
When a network increases the number of devices capable of
accessing it, there needs to be adequate resources available for
doing so. Failure to have necessary expansion capabilities can
hinder potential of the network and prevent future
advancements.
All though some efforts within a network can be
classified as redundant, there are clearly needs for redundancy
in well-tuned networks. These redundancies ensure that similar
processes and procedures are followed through with on each
occasion. When there is a failure to a given area within a
network, it is possible to pin-point the area at fault with
appropriate understanding of redundancies. This element also
plays a crucial role when seeking to expand a network, as the
previously determined guidelines are already in place for the
new configuration to adapt to. When integrating addition
devices, the easier the process can be, the better it is for
network and the network administrator(s).
There are many pieces to a network that require
subsequent actions to be possible. In other words, many factors
leading up to a certain process are required for the current
process to be functional. One area that this is evident is with the
use of multi-threading and multiple channel distribution.
Important factors such as stream lined communications need to
be efficient and dependable in order for multiple outlets to
process and distributed data through various channels. If a fault
is preventing information flow from one channel it can affect
other channels performance. Wireless and Wide Area Network
functionality with a LAN environment can be beneficial to a
network for many reasons. There are several key attributes that
need to be accounted for when attempting to seamlessly blend
LAN and WAN together.
1. Identifying the Physical and Logical Locations of
Important internetwork Equipment, for example, Routers,

7. Switches, and Firewalls.
2. Documenting the names and Addresses of Existing
Network Servers and Interconnection devices.
3. Documenting the Types and Lengths of the Physical
Cabling and All the Layer Two Circuits.
Scalability and highly available WAN network is going to play
an important role into Riordan Manufacturing and Technical
goals because will improve all activities between their
headquarters, from San Jose, Albany, GA, Pontiac, MI,
Hangzhou, China, and the new relocation in Shanghai. Because
the company’s connectivity relies on services from external
sources is important ensure that the service providers offer to
the company a very competitive service level agreement (SLA)
to guarantee a scalable and reliable enterprise WAN network.
The service level agreement guarantee the best availability the
provider can promise. It is important if the provider does not
offer a trustworthy service level agreement for all WAN links.
The company should switch to a new provider who can offer it.
In addition, it is necessary make sure the WAN links are more
scalable and reliable.
Another important fact is that Riordan need to consider is
a backup WAN links. To obtain a reliable WAN is necessary to
add a backup WAN link to the primary link and to configure the
routers. This will provide a high quality of availability of all the
WAN service includes if the primary link goes down. For
example, Riordan Manufactory should add an ISDN backup
circuit to the primary T2, and T3.
Another new way to implement a reliable WAN network is
multi-homing the WAN using BGA4, which is a configuration
of several network interfaces IP addresses, which allow the
enterprise network to have more than one entry point into the
Internet. In addition, this provides fault tolerance for
applications requiring Internet access and high availability for
enterprise public accessible servers, such as public e-mail web
servers. Due Riordan Manufacture consist of several
headquarters we suggest to use the Border Gateway Protocol

8. which is used to make core routing decisions on the Internet,
and allows to the enterprise to create loop free, inter domain
routing between different autonomous systems.
Another, important fact that Riordan Manufacture needs to
considers selecting the best routing protocol. Considering that
our team is proposing equipment from Cisco one of the best
protocols that we can suggest is Open Shortest Path First
(OSPF) which is ease of deployment and fast convergence, it is
appropriate for large company, such as Riordan Manufacture,
and it maintains all of the advantages of Link State protocols.
Some of the features include (Cisco, 2013):
· Support IPv4 and IPv6 networks and it is easy transition to
IPv6
· For large dynamic multipoint and Virtual Public Network
deployment is superior scaling of Interior Gateway Protocol
· Only routing table changes, not the entire routing table, are
propagated when change occurs
· It is more efficient use of links, through equal cost multipath
and unequal cost load sharing
This protocol will be compatible with the rest of the network
because come from the same Cisco Company. In addition,
Riordan will have a strong WAN by ensure and service level
agreement, a backup WAN links, and using multi-homing using
BGP4 will guarantee a scalable and reliable for the company.
