Abstract: PURPOSE: A packet transfer method for duplexing protocols of a network layer and a transmission layer is provided to enable protocols to perform the same process simultaneously in an active board and a standby board. CONSTITUTION: Virtual interfaces(103,113) handle a task related to a path of packets. A packet having layer header information(201-203) comes into an active main processor board(101). When the packet passes a virtual interface layer(L2), its L2 layer header(MAC header(201)) is removed and thus the packet is changed to a packet(205) having only an L3 header. The packet(205) is copied so that the original one(205) is transferred to an upper protocol stack(102) and the copied packet(207) is transferred to a processor board(116) in a standby state through a duplex ether path(104). When the copied packet(207) is transferred, the L2 layer header(MAC header(201)) is attached to the copied packet(207). Accordingly, Ethernet physical device(105) of the active processor board(101) and the Ethernet physical device(112) of the standby processor board(116) have the same MAC address and IP address.
Abstract translation: 目的：提供一种网络层和传输层双工协议的报文传输方式，使协议能够在活动板和备用板中同时进行相同的处理。 构成：虚拟接口（103,113）处理与数据包路径有关的任务。 具有层标题信息（201-203）的分组进入活动主处理器板（101）。 当分组通过虚拟接口层（L2）时，其L2层报头（MAC报头（201））被去除，因此分组被改变为仅具有L3报头的分组（205）。 复制分组（205），使得原始（205）被传送到上层协议栈（102），并且复制分组（207）通过双工以太网路径被传送到处于待机状态的处理器板（116） （104）。 当复制的分组（207）被传送时，L2层头（MAC头（201））附加到复制的分组（207）。 因此，有源处理器板（101）的以太网物理设备（105）和备用处理器板（116）的以太网物理设备（112）具有相同的MAC地址和IP地址。
