QoS Features

Methods of faster data transfer...

5G's QoS solution will allow you to get the appropriate level of service from your online applications so that you can offer your customers the appropriate levels of service that they rightly deserve. In order to ensure that data is being correctly shared amongst your applications, there are various measures that are taken.

We have listed these, for your interest, below:

Priority Queuing

The oldest of the queuing techniques is Priority Queuing. Using this method, traffic is prioritized with a priority-list, applied to an interface with a priority-group command. Depending on the application you wish to concentrate on, the traffic will go into one of four queues: high, medium, normal, or low priority. From here, when the broadband router is ready to send through a data packet, it will first search the high priority queue for a packet. If it finds one, the packet is sent, if not, the medium queue is checked and so on until the low priority queue is checked and any packets there are sent. This process then repeats for the next packet.

Generally intended for use on low bandwidth links, it ensures that the high priority traffic must go out the interface at all costs, and any other traffic can be dropped.

Custom Queuing

With Custom Queuing, up to 17 queues are used to effectively distribute bandwidth across an interface. The system queue, or Queue 0 will always be serviced first, being used for critical interface traffic, including keepalives. Any remaining traffic is assigned through queues 1 to 16. These queues are serviced periodically in numerical order.

Custom Queuing is aimed at even distribution of bandwidth to provide the best possible service for your business critical applications. So for example, you may set it up so that IP receives roughly 50% of a link, DLSw 25%, and IPX 25%. This method works by sending packets from each queue in turn. As each packet is sent, a byte counter is employed. Once the byte counter has exceeded the default or configured threshold for one queue, transmission is moved on to the next queue. Each time a queue is moved down, the byte limit is decreased to provide additional fairness to the mechanism.

Weighted Fair Queuing

In this method of QoS, traffic streams are automatically sorted without the need for the user to first define the access lists. Using Weighted Fair Queuing, both one and two way streams of data can be managed, i.e. traffic between pairs of applications, or voice and video management. This method also automatically smooths out network bursts to reduce latency.

With Weighted Fair Queuing, data packets are sorted by weight to determine transmission order. So the effect of this method could be seen as classifying sessions as either high or low bandwidth, with low bandwidth applications getting priority over high bandwidth traffic, which shares whatever is left over.
