Question

Perform research beyond the textbook to identify metrics that can be used to determine issues with network congestion or bottlenecking of data on a network. Then in your own words, identify how these metrics can be used to diagnosis and resolve network congestion.

Answer 1

Network congestion:

In computer networking and queuing theory reduced service quality when a network node is transferring more data than it can handle. It typically effects include the packet loss, network delay and losses of connections.

When too many packets are contending for the same link it will be effected the following

1. The queue overflows
2. Packets get dropped
3. Network is congested!

There are some causes to occur the congestion

1. Too many hosts connected in same broadcast domain

When you place too many hosts in a broadcast domain it can creates the network congestion.

2. Broad cost storm

Storm means request, so many requests in the same network it can create congestion or bottle neck.

3. Less band width

When we are using low band width network and push more date on to the network causes creates the bottleneck.

4. Adding retransmitting hubs

When building out a network there needs to be the integration of hubs, hubs retransmit data over a network. Hub means what are the things connected to our public network.

5. Multicasting

Multicasting means two packets send at the same time can causes the collision. This collision causes network congestion.

6. Outdated hardware

Most of the times we are using existed hard ware like switches routers and other network equipment, it causes the network bottlenecks

7. Bad configuration

Fat fingers and misconfiguration are two things that can cause network congestion.

8. Border gate way protocols

Border gateway protocol can be creating network congestion, it can sends all the traffic through the shortest logical path. It is not consider how much data transferred at present over the path.

To monitor the above significant we can resolve the network congestion
