approaches for emulating network conditions

[flyingzl]

In general, it seems that we have the following two methods for emulating network conditions.

• emulateNetworkConditions API provided by Chrome DevTools Protocol, lpp-network-trace Emulator have utilized this API to simulate time-variant network conditions.

• TC/netem，DummyNet and equivalent tools at OS level. Guys from Akamai provided A GOOD EXAMPLE to utilize this method.

Currently, OS level emulation tools are not used by the Browser devtools, so I think this is still an open topic for us to discuss.
