Description
Technical field
The present invention relates to communication fields, more particularly to message processing method and device.
Background technique
In an ip network, when message length is more than MTU (Maximum Transmission Unit, maximum transmission unit)
When, data sending terminal needs to transmit message fragment, after data receiver receives fragment, according to the offset information weight of fragment
Group goes out complete message.Fragment passes through the gateway based on connection status, firewall such as based on state-detection, with NAT
When the router of (Network Address Translation, network address translation) function, it is also desirable to be carried out to fragment message
Recombination, could finishing service processing.
With the expansion of network size, web database technology is continuously increased, in order to improve the processing capacity of gateway, more
It is designed to distributed structure/architecture come more high-end gateways.Distributed structure/architecture generally includes master control borad, interface board and business
Plate is communicated by internal bus between these boards, and as shown in FIG. 1, FIG. 1 is the distributed structure/architecture gateways of the relevant technologies
The schematic diagram of system composition.Wherein, master control node of the master control borad as system, interface board external connection to network, business board pair
Flow into system carries out business processing.When IP packet reaches interface board, interface board according to the five-tuple information of message (i.e.
Source IP, destination IP, protocol number, source port, destination port) cryptographic Hash is calculated, and be diverted to message according to the cryptographic Hash
Purpose business board.For a size is more than MTU and the IP package of fragment transmission, only first fragment message has included
Whole five-tuple information, remaining fragment only include source IP, destination IP and protocol number, do not include source port and destination port, interface
Plate can not will be shunted according to five-tuple shunting information according to the binary group information of message.It is based on five-tuple and binary as a result,
The hash algorithm that group shunts not can guarantee the fragment message of same connection and non-fragment message calculates identical cryptographic Hash, thus
Cause fragment and non-fragment message based on same five-tuple information that may be divided to different business boards.
Summary of the invention
It is same the technical problem to be solved by the present invention is to not can guarantee under current distributed structure/architecture to the mode of message shunting
The problem of fragment message of five-tuple and non-fragment message are assigned to same business board is based on the problem, the present invention provides
A kind of message processing method and device.
According to an aspect of the invention, there is provided a kind of message processing method, comprising: the business board of distributed system exists
When receiving message, judge whether message is fragment message；If not, message is handled by business board, if so, carrying out to message
Recombination, the purpose business board of message is determined according to the five-tuple information of the message after recombination；Message is sent to purpose business board.
Wherein, the purpose business board of message is determined according to the five-tuple information of the message after recombination, comprising: after recombination
Message five-tuple information carry out Hash calculation, obtain the first cryptographic Hash；Corresponding purpose industry is searched according to the first cryptographic Hash
Business plate.
Further, the above method further include: distributed system business board before receiving message, distribution system
Whether the message that the interface board judgement of system receives is fragment message, if so, carrying out Hash according to the binary group information of message
It calculates, obtains the second cryptographic Hash, the message received is sent to by corresponding business board according to the second cryptographic Hash, if it is not, then
Hash calculation is carried out according to the five-tuple information of message, obtains third cryptographic Hash, the message that will be received according to third cryptographic Hash
It is sent to corresponding business board.
Wherein, the binary group information of fragment message includes: the source IP address and purpose IP address of fragment message.
Further, the above method further include: before message is sent to purpose business board, carry purpose in messages
The identification information of business board；When message reaches business board, purpose business panel sign is deleted.
According to another aspect of the present invention, a kind of message process device is provided, comprising: first judgment module is used for
The business board of distributed system judges whether message is fragment message when receiving message；Determining module, for sentencing first
When the judging result of disconnected module is no, message is handled by business board, when the judging result of first judgment module is to be, to message
It is recombinated, the purpose business board of message is determined according to the five-tuple information of the message after recombination；Sending module is used for message
It is sent to purpose business board.
Wherein it is determined that module includes: computing unit, by being carried out based on Hash according to the five-tuple information of the message after recombination
It calculates, obtains the first cryptographic Hash；Searching unit, for searching corresponding purpose business board according to the first cryptographic Hash.
Wherein, device further include: the second judgment module, for the business board in distributed system receive message it
Before, whether the message that the interface board judgement of distributed system receives is fragment message；Sending module is used for: judging mould second
The judging result of block is to carry out Hash calculation when being according to the binary group information of message, obtain the second cryptographic Hash, breathe out according to second
The message received is sent to corresponding business board by uncommon value, when the judging result of the second judgment module is no, then according to report
The five-tuple information of text carries out Hash calculation, obtains third cryptographic Hash, is sent to the message received according to third cryptographic Hash
Corresponding business board.
Wherein, the binary group information of fragment message includes: the source IP address and purpose IP address of fragment message.
Further, above-mentioned apparatus further include: mark module, for before message is sent to purpose business board,
