Assume that an average SNMP message is 100 bytes long. Assume that a manager sends 40 SNMP Get commands each second. a) What percentage of a 100 Mbps LAN link’s capacity would the resulting response traffic represent? b) What percentage of a 128 kbps WAN link would the response message represent? What can you conclude from your answers?
To answer these questions, we need to calculate the amount of traffic generated by the SNMP Get commands per second and then compare it to the capacity of the LAN and WAN links.
First, let's calculate the amount of traffic generated by the SNMP Get commands per second:
Number of SNMP Get commands sent per second = 40
Size of each SNMP message = 100 bytes
Total traffic generated per second = Number of SNMP Get commands sent per second * Size of each SNMP message
= 40 * 100 bytes
a) What percentage of a 100 Mbps LAN link's capacity would the resulting response traffic represent?
To calculate this, we need to find the capacity of the LAN link in bits per second and then calculate the percentage.
Capacity of the LAN link = 100 Mbps = 100 * 10^6 bits per second
Percentage of LAN link capacity = (Total traffic generated per second / Capacity of the LAN link) * 100
= (40 * 100 bytes / (100 * 10^6 bits per second)) * 100
b) What percentage of a 128 kbps WAN link would the response message represent?
To calculate this, we need to find the capacity of the WAN link in bits per second and then calculate the percentage.
Capacity of the WAN link = 128 kbps = 128 * 10^3 bits per second
Percentage of WAN link capacity = (Total traffic generated per second / Capacity of the WAN link) * 100
= (40 * 100 bytes / (128 * 10^3 bits per second)) * 100
Now, let's calculate these percentages:
a) Percentage of LAN link capacity = (40 * 100 bytes / (100 * 10^6 bits per second)) * 100
b) Percentage of WAN link capacity = (40 * 100 bytes / (128 * 10^3 bits per second)) * 100
After calculating these percentages, you can conclude the following:
- If the resulting percentages are significantly below 100%, it means that the SNMP response traffic is not utilizing the full capacity of the LAN or WAN link. This suggests that there is available bandwidth on the network.
- If the resulting percentages are close to or above 100%, it means that the SNMP response traffic is nearing or exceeding the capacity of the LAN or WAN link. In such cases, the network may become congested, leading to potential issues with delay or packet loss.
By analyzing these percentages, you can assess the impact of SNMP response traffic on the network links and make necessary network capacity adjustments if needed.
