-### TrafficShaping
+### Bandwidth
 
 The `bandwidth` field enables traffic shaping for an Egress, by limiting the
 bandwidth for all egress traffic belonging to this Egress. `rate` specifies
 the maximum transmission rate. `burst` specifies the maximum burst size when
 traffic exceeds the rate. The user-provided values for `rate` and `burst` must

 e.g. 300k, 100M, 2G. All backend workloads selected by a rate-limited Egress share the
 same bandwidth while sending egress traffic via this Egress. If these limits are exceeded,
 the traffic will be dropped.
