    • A method and Bridge in a Provider Backbone Bridge Network (PBBN) for enabling frames from a Higher Layer Entity attached alternatively to a Provider Instance Port (PIP) on an I-Component of a Backbone Edge Bridge or to a Customer Backbone Port on a B-Component of the Backbone Edge Bridge, to reach an intended entity in the PBBN. A Virtual Instance Port Service Access Point (VIP SAP) is configured for every VIP and every Higher Layer Entity configured on the I-Component. An Enhanced VIP Port Connectivity function utilizes the VIP SAP to tunnel customer-initiated Layer 2 Control Protocols (L2CPs). A Special Multiplexed SAP handles the frames of the Higher Layer Entity, and is assigned an I-SID value that is universally recognized to identify the L2CPs. A Service Instance Multiplex Entity utilizes the Special Multiplexed SAP to transfer frames between the PIP or the Customer Backbone Port and the entity inside the PBBN.
    • 提供者骨干桥网络(PBBN)中的方法和桥接器,用于使来自更高层实体的帧可替代地连接到骨干边缘桥的I组件上的提供者实例端口(PIP)或B上的客户骨干端口 - 骨干边缘桥梁的组件,以达到PBBN中的预期实体。 虚拟实例端口服务接入点(VIP SAP)被配置为在I组件上配置的每个VIP和每个更高层实体。 增强的VIP端口连接功能利用VIP SAP来隧道客户发起的第2层控制协议(L2CP)。 特殊的多路复用SAP处理较高层实体的帧,并分配一个普遍被识别以识别L2CP的I-SID值。 服务实例复用实体利用特殊复用SAP在PIP或客户骨干端口与PBBN内的实体之间传输帧。
