Q32.
My company uses a Financial Application across the internet, and I want to
ensure that this traffic is prioritized over all other traffic.
Ans:
Configure HTB QoS on the WAN interface as explained in Q31. This will ensure
that this router prioritizes your application over all other traffic.
To ensure that every hop router prioritizes your application, configure the TOS/DiffServ
feature to appropriately set the TOS Octet in the IP Header of your application packets.
For example, a TOS Value of “00111101” can be used for critical traffic which should be
transmitted with low delay, high reliability and high throughput.
