Leased Line Traffic Management

What is traffic management or shaping?

Data usage is growing at a continual exponential rate. This brings with it challenges for operators and network end user businesses.

Operators need to be able to manage the growth of IP on their networks to balance effective scaling with service guarantees.

End user businesses need to manage the allocation of traffic across their networks so that essential services have the bandwidth to operate effectively.

Traffic management solutions help service providers and business network managers solve these challenges by controlling the traffic types across their network infrastructure. The result is a scalable, high-performance network that delivers a high quality of experience and maximises profitability.

QOS quality of service

What is quality of service (QOS) and how does this help?

Quality of service is the application of intelligent routing according to the network usage. It is a feature of routers and switches which prioritizes traffic so that more important traffic can pass first. The result is a performance improvement for critical network traffic. QoS equipment is useful with VoIP phones or in LANs with high volumes of local traffic.

For example VoiP phone call traffic can be allocated a higher priority than You Tube video streaming. By enforcing a rule like this the network manager can be assured that mission critical applications such as voice will always have priority no matter how busy the network is.

How can I apply QOS on my network?

The application of QOS is performed on both your local router and across your network routing. It is therefore something which you need to implement on your own equipment and in conjunction with your network provider.

It is important to identify the need for QOS early in your procurement process as not all network solutions can offer end to end QOS. If you require this then you will usually need to purchase an MPLS network offering.

A good example of where QoS is needed is VoIP traffic. VoIP traffic needs to be delivered within a certain time to the destination, or it becomes obsolete. Therefore, QoS should prioritize the VoIP traffic to ensure that it is delivered within a certain time constraint. To achieve this, it is possible within Cisco IOS to queue VoIP with a higher priority than FTP or HTTP traffic and to make sure that if congestion occurs, FTP or HTTP traffic is dropped ahead of the VoIP traffic. Cisco IOS has several mechanisms to do this on a router.
