The following chart represents the estimated total capacity of the backbone traffic.

Application	Percent Distribution Per Segment	Number of Simultaneous Sessions	Average Transaction Size	Estimated Total Capacity Required
SNMP	100%	324,000/hour	74KB	52.03 Mbps
Email	100%	23/hour	1.5MB	0.08 Mbps
Backup	100%	1/hour	50GB 51,200MB	113.78 Mbps
			Total	165.886 Mbps

SNMP

Step 1 – Determine Sessions Per Second – 324,000 / 3,600 = 90 SPS
Step 2 – Obtain KBps by Multiplying – 90 x 74KB = 6,660 KBps
Step 3 – Convert to Kilobits per second (Kbps) – 6,660 x 8 = 53,280 Kbps
Step 4 – Convert to Megabites per second (Mbps) – 53,280 / 1,024 = 52.03 Mbps
Step 5 – Repeat for all remaining applications and sum for total traffic.

Total of all Backbone Traffic: 52.03 + 0.076 + 113.78 = 165.886 Mbps

If you had a 1 Gbps backbone, it could be stated that you are utilizing almost 16.2%, which is well under the 40% maximum guideline.
