Embodiment

[0088] Step 211: Establish an auxiliary information buffer pool on the NFC, allocate all auxiliary information blocks, each auxiliary information block corresponds to a unique serial number, and initialize all auxiliary information blocks.

[0089] Open up a continuous storage space on the NFC as an auxiliary information buffer pool. NFC divides the auxiliary information buffer pool into several auxiliary information blocks with the same storage space, and each auxiliary information block sets a unique corresponding serial number. In addition, the NFC sets the status flags of all auxiliary information blocks to an idle state.

[0090] Step 212: When the NFC performs redirection rule matching on the message flowing through the NFC, if the message matches a redirection rule successfully, save the auxiliary information of the redirection message, and send the message to the specified IAC.

[0091] For a successfully matched message, the NFC first saves the supplementary informa...

Abstract

This invention provides a method for recovering and redirecting message character information including: 1, a first part carries out match of redirection rule to messages flowing through local part and stores the character information of the successful messages, 2, the first part redirects said message to the second part and the message caries the identification information of the redirected message character information found out in the first part when returning the message, 3, the first part receives the message returned by the second part to recover the character information of the original message based on the identification information carried in the message.

Description

technical field [0001] The present invention relates to the network field, in particular to a method for restoring characteristic information during redirection between NFC (Network Forwarding Component, network forwarding component) and IAC (Independent Application Component, independent business component) in OAA (Open Application Architecture, open application architecture) And IAC and NFC that apply the method. Background technique [0002] With the rapid development and gradual refinement of network services, traditional network devices are no longer handy in handling these services. For example, devices are required to be able to forward data and access voice, and devices are required to perform load sharing and content security filtering. At this time, it is difficult for an independent technology manufacturer to provide all the services required by users at the same time. For this reason, users generally need to purchase equipment from multiple manufacturers and co...
