We simulated a scenario where a bulk data transfer (simulating a firmware update) consumed 80% of the bandwidth. We then measured the Round Trip Time (RTT) of a ping packet sent every 100ms.

In a standard stack, data flows vertically. In jqbt, the jqbt_top interface acts as a gatekeeper. When an application creates a socket, it specifies a JQ_PRIORITY_CLASS . The jqbt_top module intercepts these calls and tags the socket buffer (skb) with a hardware-enforceable priority tag.

Alex had always been fascinated by the world of technology. As a young programmer, he spent countless hours tinkering with code, experimenting with new gadgets, and optimizing software. One day, while working on a project, Alex stumbled upon JQBT, a lightweight, open-source media player that had gained a significant following among audiophiles. He was impressed by its simplicity and flexibility, but there was one major caveat: the Bluetooth driver was subpar.
