Description
Technical field
The present invention relates to computer network data communication technical field, more particularly to a kind of masterslave switchover and load sharing
Network equipment system.
Background technology
The network equipments such as mid-range-and-low-end routers, interchanger are the indispensable visual plants of data communication field, are existed at present
Processing of the commercial equipment to packet chain of command and forwarding surface is substantially following several modes in various networks：
1st, traditional sense master control borad is switched, and takes various measures to ensure the stability of master control board switching, is held
Mistake etc., but there is no redundancy protecting to forwarding surface；System is only backuped to master control borad, and conversion board is not backed up.Once turn
Send out plate to break down, the data forwarding flow that the interface below this conversion board receives will abandon entirely, cause service disconnection；
2nd, master control borad and conversion board all back up, but there was only master control borad and the work of main conversion board during system worked well, standby
Master control borad and standby conversion board are Status of Backups, and the forwarding resource wave of standby conversion board is so caused in system worked well
Take；
3rd, load sharing is only supported in system between the forwarding card of part, active and standby, a pair of forwarding cards are only supported between the forwarding card of part
Between can not support load sharing and active and standby simultaneously；
4th, two pieces of conversion boards dock one piece of interface board, and two pieces of conversion boards of normal condition share interface board and receive the forwarding data to come,
Masterslave switchover occurs during one piece of conversion board failure, all forwarding data are sent to another piece of conversion board processing.Although forwarding surface is born
Lotus is shared, but forwarding surface bandwidth is not lifted.
, can either be to forwarding it is therefore desirable to provide a kind of method and network equipment system of masterslave switchover and load sharing
The active and standby of face is backed up, and ensures the stability in system forwards face；The load sharing of converting flow, lifting system are disclosure satisfy that again
Forwarding surface bandwidth.
The content of the invention
, can be to forwarding surface it is an object of the invention to provide a kind of masterslave switchover and the network equipment system of load sharing
The active and standby stability for being backed up, ensureing system forwards faces；The load sharing of converting flow is disclosure satisfy that again, and lifting system turns
Fermentation bandwidth.In order to realize foregoing invention purpose, the technical scheme is that：
A kind of network equipment system of masterslave switchover and load sharing, including hardware components and software section, hardware components are main
Including two pieces of master control borads, two pieces of business conversion boards, two group interface plates；Software section includes system control module, business-driven mould
Block, forwarding module, interface board control module；
Control axis of the master control borad as the present invention, carries the operation of whole software systems；Every piece of master control borad has two to disappear
Passage is ceased, connects two pieces of conversion boards respectively；Also there is a message channel between two pieces of master control borads, for synchronically controlling information and be
System state；
Conversion board, for handling all business converting flows, every piece of conversion board has two first line of a couplet message interfaces, connects two pieces respectively
Master control borad；Every piece of conversion board has two groups of second line of a couplet interfaces, is connected respectively with two group interface plates；There is high-speed data between two pieces of conversion boards
Forwarding channel；
There are two upper connecting ports on interface board, for connecting two pieces of conversion boards.
System control module is mainly operated in above master control borad, is responsible for the control to machine system operation；
Business-driven module is mainly operated in above conversion board, the forwarding information that primary recipient system control module issues, and is integrated
The forwarding-table item needed into forwarding module；
Forwarding module is mainly operated in above conversion board, and the business converting flow for entering conversion board is handled；
Described interface board control module is mainly operated in above interface board, the message that meeting reception system control module is sent, is cut
Connecting port is changed, conversion board is corresponded to being sent to from the data forwarding flow of outer reception.
During normal work of the present invention, only one piece of master board is in running order, and another piece is in Status of Backups.Once
Masterslave switchover operational order is broken down or received in master board, and master board can restart, and standby control panel is changed into master board,
The operation of adapter whole system.
Every piece of conversion board has two first line of a couplet message interfaces, connects two pieces of master control borads respectively.Every piece of conversion board has two groups of second lines of a couplet
Interface, for connecting interface plate.Every piece of interface board has two upper connecting ports, for connecting two pieces of conversion boards.Two pieces of conversion boards
All normal work when, converting flow that the first group interface plate receives can on be sent to the processing of the first conversion board, the second group interface plate connects
The converting flow of receipts can on be sent to the second conversion board processing.If the first conversion board breaks down, control system is notified that first
The upper connecting port of group interface plate switching, is handled the second conversion board is sent on converting flow.Likewise, if the second conversion board goes out
Existing failure, control system are notified that the upper connecting port of the second group interface plate switching, located the first conversion board is sent on converting flow
Reason.There is high-speed data forwarding channel between two pieces of conversion boards, it is possible to achieve the first group interface plate and the second group interface plate forwarding flow
The intercommunication of amount.Two pieces of master control borads of the system form the man-to-man backup of chain of command, two pieces of conversion boards and two group interface plate shapes
Into the active/standby backup and load sharing in data forwarding face.The active/standby backup of forwarding surface can either be provided, ensure system forwards face
Stability, disclosure satisfy that the load sharing of converting flow, lifting system forwarding surface bandwidth again.
