    • A method is provided in one example and includes querying for a total capacity for data transmissions for a local network segment, and identifying an available capacity for the local network segment by subtracting a sum of current aggregate consumption of the local network segment from the total capacity. The method also includes comparing the available capacity to a requested capacity that is generated by a network element for a specific communication session. If the requested capacity is equal to or greater than the available capacity, the request is withheld and not transmitted. In more specific embodiments, if the requested capacity is less than the available capacity, the request is transmitted. The query can be communicated to a gateway. In still other embodiments, the query includes a specific query as to a capacity allocated for video data and the network element is a set-top box.
    • 在一个示例中提供了一种方法,并且包括查询本地网段的数据传输的总容量,以及通过从总容量中减去本地网段的当前总消耗量的总和来识别本地网段的可用容量 。 该方法还包括将可用容量与由特定通信会话的网络元件生成的所请求容量进行比较。 如果所请求的容量等于或大于可用容量,则请求被拒绝并且不被发送。 在更具体的实施例中,如果所请求的容量小于可用容量,则发送该请求。 该查询可以传送到网关。 在其他实施例中,查询包括关于为视频数据分配的容量的特定查询,并且网络元件是机顶盒。
