ISSUE-128: Need more description on how bandwidth should be estimated

Need more description on how bandwidth should be estimated

State:
POSTPONED
Product:
Network Information API
Raised by:
Giridhar Mandyam
Opened on:
2012-12-01
Description:
Current specification states that bandwidth (when UA can estimate it) should be "an estimation of the current bandwidth in MB/s (Megabytes per seconds) available for communication with the browsing context active document's domain."

There needs to be more specificity as to how the UA should estimate bandwidth. For instance, a UA that estimates bandwidth only on the basis of the previous resource request may exhibit significant variability in the bandwidth estimation. On the other hand, a UA that estimates bandwidth by smoothing over a long time period may provide an unusable estimate.

Related notes:

[fjh]: note in spec about issue is in section 1.2 Outstanding issues : "One concern is that bandwidth may be hard to implement, can be quite power-consuming to keep up-to-date and its value might be unrelated to the actual connection quality that could be affected by the server.
