Why my network is slow?

Why my network is slow?

 Why my network is slow? That is a common question.

network slownetwork

That is a common question shared by anyone who is part of the company, always expressed with sentence stress of not completing some work on time, often with frustration at failing to meet at other times serving as an excuse to justify delayed delivery of any jobs

There are a large number of possible causes of slow network, under the following part common causes will be listed.

1 .- Viruses on the network
Probable PC infected with viruses trying to infect other PC in this process by sending traffic and congested network resources

2.-Failed PC

Failed NIC from any PC Causing high network utilizations as a consequence high level of switch CPU processing will be observed making network to stop responding properly

A higher impact is done in networks without vlans

3.-Bad configuration or connections from switches and routers

As an example a common problem is a PC connected trough several ports to the same switch without a channel group configuration

4. – Server or services failure.

5.-Tasks or jobs that normally causes network congestion.

Setting business PCs to download patches for Windows or Antivirus without specification of time, this has caused during office hours 100 or 200 pcs try to update patches becoming a severely congested network

6. – Denial of service attacks
Many companies use large resources to protect themselves from hackers in the world but do not look to the internal staff that voluntarily and involuntarily can cause damage to the network through attacks designed to stop the network through congestion of network resources

The above points are just a sample of what can make your network slow, when problems occur the level of urgency to address them is very high, these slowness problems a great majority of times are difficult to resolve.

It takes a great experience and measurement tools to allow visibility of network behavior at this stage it is advisable that you obtain advice from an expert who will help to reduce response times, even better would be to proactively analyzed the network and identify vulnerabilities for avoid future network problems
