    • The system of the present invention guarantees quality of service with respect to packets transmitted/received between an external network capable of providing differentiated services and a home network. The system includes a packet classifier, a marker, a priority class queue, a scheduler and a token bucket. The packet classifier classifies the packets according to addresses and traffic types. The marker allocates information on priorities to packets transmitted from the home network to the external network. The priority class queue has a plurality of queues classified according to the priorities. The scheduler services packets stored in the priority class queue according to the priorities. The token bucket drops packets, bandwidths of which are above a preset maximum bandwidth, when the packets are generated.
    • 本发明的系统保证了能够提供差分服务的外部网络与归属网络之间发送/接收的分组的服务质量。 该系统包括分组分类器,标记,优先级队列,调度器和令牌桶。 分组分类器根据地址和流量类型对报文进行分类。 标记将从家庭网络传送到外部网络的分组的优先级信息分配。 优先级队列具有根据优先级分类的多个队列。 调度器根据优先级对存储在优先级队列中的数据包进行服务。 当生成数据包时,令牌桶丢弃其带宽高于预设最大带宽的数据包。

    • Provided is a method of resource management and call admission control in an access network in a hierarchical manner.The method of resource management and call admission control in an access network includes: (a) collecting resource information on all of devices constituting the access network and hierarchically constructing the resource information on the access network; (b) when a user requests a connection to the access network, hierarchically extracting position information on the access network from the resource information and connecting the extracted position information to link information in the hierarchically constructed resource information; (c) when a user who succeeds in connecting requests call admission control for an IP communication service, determining an availability of the resources of the hierarchically constructed position information; and (d) when the availability is certified, allocating a band required to the IP communication service to the link information and a part of a margin band of a service class to which the user belongs to respond to the call admission control request.
    • 提供了一种以分级方式在接入网中进行资源管理和呼叫准入控制的方法。 接入网中资源管理和呼叫准入控制的方法包括:(a)在构成接入网的所有设备上收集资源信息,并在接入网上分层构建资源信息; (b)当用户请求连接到接入网络时,从资源信息分层提取接入网络上的位置信息,并将所提取的位置信息连接到分层构造的资源信息中的链路信息; (c)当成功连接请求的用户呼叫用于IP通信服务的接纳控制时,确定层次构造的位置信息的资源的可用性; 以及(d)当可用性被认证时,将IP通信服务所需的频带分配给用户所属的链路信息和服务类别的边缘带的一部分以响应于呼叫许可控制请求。
