How do you plan
• Sales gathers information
• Hands information to planning and to the Network
Architecture team to design the network and do a costbenefit analysis. (i.e., will it pay for itself and make us
profitable?)
• Submit request to finance for approval. (Business plan
approval)
• Back to Planning once approved to finalize the design.
• Then to the Network Engineering to implement, test and
turn up the equipment.
• Completed design goes into system so that its capacity
can be sold, provisioned and monitored.
• Sales gathers information from customers
and from survey’s, etc. and determines a
demand.
• Network Architecture works with the
vendor to test equipment and get pricing
contracts signed.
• Planning works with Network Architecture,
the vendor to get right equipment for
lowest cost and to get delivery estimates.
Network Traffic Planner
• Verifies with other planning groups before
submitting the plan.
•
•
•
•
Facilities planning – is there space for the equipment?
Power planning – Is there sufficient power?
Can the equipment be timed and monitored?
Do we have sufficient fiber between the cities to
support the equipment (OSP – Fiber).
• Are we able to drop where the customer wants
us?
• Provide information back to these groups for
forecasting.
What does the planner have to know?
• How does the equipment work? (all of the
equipment)
• How do you protect that traffic in case
there is a network failure?
• They have to know the financials- Is this the
best cost solution or is there a cheaper way to do this
without spending money?
• How long with this build last – when will we
need to do the next overbuild based on trending?
• How to monitor the network – how can I see
how fast we are growing or when I should plan for the
next build?
What skill-sets do you need?
• Attention to detail
• Database knowledge is a real plus.
(Access, SQL, etc. – know how to use them.
You will be analyzing a lot of data and this
makes it easier).
• As in anything – hard work
