Linuxネットワークスケジューラ（tc qdisc）のPOLICEDという名前は、

Question

POLICEDは、入力パケットの速度が制限され、超過するパケットが廃棄されることを意味します。

include/linux/netdevice.hの "skb is police by police"というコメントがありました。

もちろん、同様ですが、この名前の後ろには物語がありますか？

menuconfig NET_SCHED 
     bool "QoS and/or fair queueing" 
     select NET_SCH_FIFO 
     ---help--- 
      When the kernel has several packets to send out over a network 
      device, it has to decide which ones to send first, which ones to 
      delay, and which ones to drop. This is the job of the queueing 
      disciplines, several different algorithms for how to do this 
      "fairly" have been proposed.

config NET_ACT_POLICE 
     tristate "Traffic Policing" 
     depends on NET_CLS_ACT 
     ---help--- 
      Say Y here if you want to do traffic policing, i.e. strict 
      bandwidth limiting. This action replaces the existing policing 
      module. 

      To compile this code as a module, choose M here: the 
      module will be called act_police.
