Communication traffic policing apparatus and methods are disclosed. Communication traffic restrictions for each communication link in a group of communication links are enforced by allowing transfer of communication traffic associated with respective communication links of the group at transfer rates up to respective per-link transfer rates. In a group enforcement stage, transfer of additional communication traffic associated with a communication link of the group, above the per-link transfer rate for the communication link, is allowed where a combined transfer rate of communication traffic associated with another communication link of the group and the additional communication traffic would not exceed the per-link transfer rate for the other communication link. Thus, one or more individual communication links of a group may be allowed to effectively exceed their per-link transfer rates if one or more other communication links of the group have sufficient spare capacity.
