The key business drivers that led to the development of Rockwell’s global
network are:
The recognized need to speed up access to information because of customer
demand.
Handle product specifications and changes more rapidly with more control.
Leverage for advanced engineering and scientific computations that is Rockwell’s
distinctive business edge.
Implications for the types of transmission links selected for EURONET are:
More secure network because of the nature (private network).
Ability to handle data traffic without the interference of others users
that prevalent in a public network.
Transmission across great distances.
The EORONET is composed of a backbone network, which can link the main
European data center in London to Dallas, TX and Seal Beach, CA. Each data
centers have a large switch that connects it to the others through 71 T1
(1.544 mbps) digital circuits.
T1 (1.544 mbps)
T1 (1.544 mbps)
The integrated platform concept makes sense for Rockwell instead of two
seprate networks for the following major reasons:
The cost to build two networks would be exuberant.
With inceased capacity of T1 lines there is need for a duplicate network.
Situations in which an integrated network may not make sense are:
Capacity
Performance
The solution to simply increase the capacity of the private transmission
link is to use multiplexing of the data and data compression. Multiplexing
divides the transmission medium into partitions (channeling) allowing for
a larger virtual bandwidth. Data compression removes the redundant elements,
which can be regenerated at the end of the transmission.
If Rockwell had 30 major locations, instead of 3, it would make sense for
them to use a public network architecture because simply large costs and
logistics would be required to link 30 sites. Network administration issues
that are prevalent in the public network are as follows:
Security because third party intereference.
No control or troubleshooting over public network.
Upgrade dependent upon the provider of the network.
