Network Traffic Control

It is the process of reducing bandwidth congestion by managing, controlling prioritizing and reducing the flow of traffic. Traffic management is more important than any other aspect of website hosting because the smoothness of running of the website depends on how well it is able to handle traffic during peak hours. Too much traffic can cause latency, packet loss and even end in the server crashing.

There are various techniques used for efficient traffic management like traffic shaping or packet shaping, bandwidth management, putting quotas, patches. It is necessary to first measure the total network traffic and identifies the primary causes of network congestion in order to use the above mentioned tools effectively.

Network Management techniques

Traffic shaping

A method which ensures that large downloads don’t get in the way of net access by hogging the entire bandwidth all day long. This is done by generally limiting the bandwidth allotted to that specific file.

It is very efficient in improving latency and increasing available bandwidth.  On the basis of certain criteria or priority, some kind of packet data is delayed so as to optimize speed for other packets.

General method of implementation of packet shaping includes delaying of metered traffic, such that each packet has to comply with traffic contract. And this is done by implementation of leaky bucket / token bucket methods.

 Bandwidth management

Another method of controlling and measuring the traffic on a network link so as to avoid filling the capacity of the link and prevent congestion.

This is done by Traffic classification- dividing traffic into specific groups on the basis of some criteria such that other tools of traffic shaping may be applied to each individual class.

Congestion Reduction

POLICING

When the number of packets exceeds the allotted traffic size for a certain bandwidth, the excess packets are either dropped or marked for future transfer.

Persistent Session routing policy

Network Traffic Control

Requests from the same user are routed to the same server by continuing the session.

Content based routing

Network Traffic Control

Requests are routed according to the content it asks for.

Server based Routing Policy

Network Traffic Control

Requests are routed to servers based on the number of pending request and overall traffic. It is assumed that each server has the same content and is able to meet any request. This is very useful in reducing workload by regulating the number of connections to the server.

Protocol based routing

Network Traffic Control

Requests are routed based on the protocol used by the client.  FTP request go to FTP servers, HTTP goes to HTTP etc.

In order to keep PCs up to date with security fixes, a lot of patching has to be done. Worms and viruses are responsible for a lot of bandwidth clogging and congestion. That is why it is necessary to remove them early.

Another way of reducing load on servers , is by limiting the bandwidth, by giving specific quotas of bandwidth to every user, for a specific period of time. This is generally don in universities and other shared networks.
