This version shall not be in the same pipeline than other TrafficShapingHandler. The general use should be as follow: Create your unique GlobalChannelTrafficShapingHandler like: `GlobalChannelTrafficShapingHandler myHandler = new GlobalChannelTrafficShapingHandler(executor);` The executor could be the underlying IO worker pool `pipeline.addLast(myHandler);` Note that this handler has a Pipeline Coverage of "all" which means only one such handler must be created and shared among all channels as the counter must be shared among all channels. Other arguments can be passed like write or read limitation (in bytes/s where 0 means no limitation) or the check interval (in millisecond) that represents the delay between two computations of the bandwidth and so the call back of the doAccounting method (0 means no accounting at all). Note that as this is a fusion of both Global and Channel Traffic Shaping, limits are in 2 sets, respectively Global and Channel. A value of 0 means no accounting for checkInterval.
