Quality on Demand (QoD)
The QoD capability allows establishing prioritized connections between your mobile device and another device or service on the internet.
It allows you to manage the amount of stable bandwidth (connection speed) and the latency (message delay) of network connections for each device, according to your current demand. This prioritized connection flow is established through what we call "QoD sessions".
What is quality of service?
This is the technology underpinning QoD. Oftentimes, predictable network performance can be difficult to achieve when there's heavy network traffic, over wide area network (WAN) connections, especially for applications or devices that will require a lot from the network. Quality of service is then used to manage and prioritize the flow of data over a network.
For instance, when prioritizing critical services like Voice over IP (VoIP), video streaming or latency-sensitive applications, it is important to ensure that different traffic types receive preferential or specific treatment, according to demand. So, by managing bandwidth, latency and balancing the network, quality of service empowers a more consistent and reliable user experience!
QoD profiles and why you need them
Now that you learned the general concept behind quality of service, it is time to talk about QoD profiles.
Since networks are shared resources, various applications/devices compete for bandwidth. So, there are certain parameters (different upload/download speeds) that you can specify to ensure how a mobile network should behave. They are what we call QoD profiles, and you must choose the desired one when programming the network.
For example, a single application could overwhelm the network unnecessarily,
in which case and whenever necessary, you could lower the bandwidth it receives
with a small up/downlink profile parameter (DOWNLINK_S_UPLINK_S).
However, some parameters need to be followed and there is a list of profiles
you can choose to address various needs.
Imagine if every user could choose their desired speeds with no limitations?
This all could lead to poorer quality, congestions or even unfairness in the network.
QoD profiles ensure developers or network administrators can allocate bandwidth to their resources, create or delete specific session flows and program the network according to their need. Learn more about QoD profiles.
