Embodiment Construction

[0039] Please refer to figure 1 The logic structure diagram of the line card board 1, the line card board 1 includes forwarding processing chip 11, logic device 12 and sub-card 13 from top to bottom, because the interfaces used by sub-card 13 and forwarding processing chip 11 are different, so logic device 12 It is mainly used to replace the package of the message sent by the daughter card 13 with the package corresponding to the interface of the forwarding processing chip 11, and perform message transmission. During the hot unplugging process of the subcard 13, if the subcard 13 currently has a message being forwarded, when the subcard 13 is hot unplugged, the complete message will be divided, resulting in only a part of the message being sent to the logic device 12 and Forward the processing chip 11. Broken newspapers will impact the forwarding processing chip 11, and even cause the forwarding processing chip 11 to hang up due to abnormal processing.

Abstract

The invention provides a method and a device for processing broken messages. The method is applied to a logic device, which is used for transmitting messages between a daughter card and a forwarding processing chip. The method comprises the steps of: detecting whether a message sent by the daughter card is a broken message; completing the message if the message is a broken one, and adding an error-reporting flag in a preset field of the message; and sending the completed message to the forwarding processing chip, so that the forwarding processing chip discards the message after recognizing that the message is broken one by means of the error-reporting flag. Therefore, impact of broken messages on the forwarding processing chip can be avoided, and forwarding performance of the forwarding processing chip can be ensured.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for processing fragmented messages. Background technique [0002] At present, on some routers, the line card board and the sub-card where the interface is located have formed a relatively mature separation mode, that is, the line card board mainly focuses on the forwarding processing chip to forward packets, and the sub-card integrates various ports. It is used to process message sending and receiving, and is responsible for converting the message into a format that the line card board can process. In order to better support the replacement of sub-cards, the hot-swapping technology of sub-cards is applied, so that the operation of plugging and replacing sub-cards can be realized without stopping the work of sub-cards. [0003] However, if the subcard is hot swapped while the subcard is forwarding traffic, there may be a certain probability of f...
