    • A dual-connection option allows preservation of network connectivity to a device or path by providing a second, redundant connection which takes over if a first connection fails. One goal is to provide communication with all critical devices at all times. If the ability to communicate with a device is lost because part of the connection to the device or the device itself has been destroyed, recovery from such loss is provided. The invention is preferably embodied in a particular implementation of the proposed Redundant Links standard, and satisfies the requirements of the proposed IEEE 802.12 standard, while adding specific enhancements to the proposed standard, such as storing and/or reporting conditions that lead up to a failure; accommodating minor, temporary disruptions; allowing status inquiries with regard to a redundant link while maintaining a primary connection; and continuing testing the redundant link after an initial verification.
    • 双连接选项允许通过提供第二个冗余连接来保留到设备或路径的网络连接,如果第一个连接失败,则连接该接口。 一个目标是随时提供与所有关键设备的通信。 如果与设备通信的能力丢失,因为与设备或设备本身的连接的一部分已经被破坏,则提供从这种丢失的恢复。 本发明优选地体现在所提出的冗余链路标准的特定实现中,并且满足所提出的IEEE 802.12标准的要求,同时添加对所提出的标准的特定增强,例如存储和/或报告导致故障的条件 ; 容纳轻微的,暂时的中断; 允许在维护主要连接时关于冗余链路的状态查询; 并在初始验证后继续测试冗余链路。

    • One embodiment disclosed relates to a networking apparatus. The networking apparatus includes a plurality of blade subsystems and a master system communicatively coupled to the blade subsystems. A particular blade subsystem is configured to provide an additional feature in relation to processing network packets. The remaining blade subsystems are configured to send non-packet information to the one blade subsystem by replacing original information in a packet with the non-packet information. The particular blade subsystem is further configured to retrieve the non-packet information from the packet. Other embodiments are also disclosed.
    • 公开的一个实施例涉及网络装置。 网络设备包括多个刀片子系统和通信地耦合到刀片子系统的主系统。 特定刀片子系统被配置为提供与处理网络分组相关的附加特征。 剩余的刀片子系统被配置为通过用非包信息替换分组中的原始信息来向一个刀片子系统发送非分组信息。 特定刀片子系统还被配置为从分组中检索非分组信息。 还公开了其他实施例。
