Close though it varies a bit from one test to another. As discussed several days ago we can mitigate (but not solve) broadband bufferbloat to a decent, if not ideal, degree by using bandwidth shaping facilities found in many recent home routers. It is used to prevent packet loss which occurs as the lower bandwidth link cannot handle traffic at the. However, it is fairly simple to address ISP bufferbloat using RouterOS's "simple queues". Developed by Kathleen Nichols and Van Jacobson as a solution to the bufferbloat problem, CoDel (Controlled Delay Management) is a queuing discipline that uses a packet’s sojourn time (time in queue) to make decisions on packet drops. The best way to imagine Bufferbloat is to picture a highway with vehicles travelling at a constant pace. Bufferbloat is when those buffers are not being managed, and therefore are oversize for extended periods, imposing excessive.
