Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is further detailed explanation.
Reference picture 1, shows a kind of step flow chart one of the embodiment of the method for looped network self-healing of the present invention, in the application
In, looped network refers to token-ring network, and the transmission method of token-ring network physically employs star topology, but in logic still
It is ring topology.
In such networks, there is a kind of special frame to be referred to as " token ", constantly transmit to determine a knot on loop
When point can send bag.Token is 24 bit lengths, there is the domain of 38, be respectively first delimiter (Start Delimiter,
SD), access control (Access Control, AC) and whole delimiter (End Delimiter, ED).First delimiter be it is a kind of with
Many different signal modes, are showed, purposes is to prevent it to be construed as other things as a kind of non-data signal.It is this
8 unique bit combinations can only be identified as frame headers and know symbol (SOF).
The media access control mechanism of token-ring network uses the round-robin method of distributed AC servo system pattern.In token-ring network
In there is a token (Token) to be transmitted successively in network access node intercomputer along ring bus, token is actually a spy
The frame of different form, itself and the use not comprising information, only control channel, it is ensured that can be only in synchronization only one of which node
Account for channel.When node on the ring is all idle, token around go in ring into.Node device could send data frame after there was only acquirement token,
Therefore it will not collide.Because token is transmitted successively in order on net ring, therefore for all log equipments, visit
The power of asking is fair.
Token has " spare time " and " busy " two states at work." spare time " represents that token does not have occupied, that is, is not set in netting
It is standby to transmit information；" busy " expression token is occupied, that is, has information to transmit in netting.Wish that the equipment for transmitting data is necessary
First it is detected that " spare time " token, it is set to the state of " busy ", then data are transmitted behind the token.When passed data are by mesh
Node device receive after, data are removed from net, and token is set to " spare time " again.
Described method specifically may include steps of：
Step 101, the malfunctioning node gateway that abnormality is in the looped network is detected；
Each node gateway has two kinds of working conditions in looped network：Normal condition and abnormality.When node gateway
When normal condition, represent that node gateway can normally receive the packet of upstream node gateway transmission, then packet is entered
Row processing, then the packet after processing is sent to downstream node gateway, when node gateway all in looped network is all in normal
During state, a looped network could be formed；When node gateway cannot normally receive upstream node gateway transmission packet, and/
Or, packet cannot be handled, and/or, it is not possible to the packet after processing is sent to downstream node gateway, all may be used
Abnormality is in predicate node gateway.
Because in whole looped network between each node being direct series connection, any one node gateway is out of order and can all made
Interruption into whole network, paralysis, therefore, in order to prevent because some or multiple node gateway failure abnormal networks
Interrupt, paralyse, or even loss of data is, it is necessary to which the working condition to all node gateways in looped network is detected.
In a kind of preferred embodiment of the invention, the malfunctioning node gateway of abnormality is in the detection looped network
The step of include：
Detect the heartbeat signal of each node gateway in the looped network；
When the heartbeat signal of node gateway, or, the heartbeat signal of node gateway can not be detected for error signal, then sentence
The fixed node gateway is in abnormality.
Heartbeat detection, it is general that simple heartbeat packet is sent using timing for judging whether counterpart device normally runs, such as
Do not receive other side's response in section at the appointed time really, then judge that other side is not online.
For example, it is for a long time, in the free time, still to have gone offline that server, which cannot be distinguished by client, then client timing is sent out
Heartbeat packet is sent to tell it me also online to server end.If not receiving the heartbeat packet of client transmission in service end a few minutes
Then it is considered as client not online.The party awarding the contract can be client or server end.In general, examining for efficiency
Consider, be that client sends heartbeat packet to server end automatically, certainly, the hair heartbeat of server end automatic regular polling is also can to client
With realization.
The embodiment of the present invention exactly detects the working condition of all node gateways in looped network using features described above.Specifically
, in looped network, packet can have both direction to carry out data transmission, when packet is according to some direction sequential delivery
When, it can be responded by the upstream node gateway heartbeat packet of gateway transmission to downstream node, downstream node gateway, then mean that
Node gateway is online.If upstream node gateway is not received by the response of downstream node gateway, then mean that downstream node
Gateway is not online, or downstream node gateway is not received by the heartbeat packet of upstream node gateway transmission, then mean that upstream
Node gateway is not online.
For example, there is tetra- node gateways of A, B, C, D in looped network, under normal circumstances, packet is the side according to A, B, C, D, A
To being transmitted, in the heartbeat signal of four node gateways of detection, A can send heartbeat packet to B, if A have received B sound
Should, then it represents that A, B are online, if B is not received by A heartbeat packet, then it represents that A is not online；If A have sent the heart to B
Bag is jumped, but is not received by B response, then represents that B is not online.
Certainly, node gateway is not meant to that node gateway is in normal condition online, hard due to node gateway
The factors such as part failure, the system failure, it may appear that although downstream node gateway is carried out to the heartbeat packet that upstream node gateway is sent
Response, but be in response to be error signal situation.So such case decides that node gateway is in abnormality.
For example, there is tetra- node gateways of A, B, C, D in looped network, under normal circumstances, packet is the side according to A, B, C, D, A
To being transmitted, in the heartbeat signal of four node gateways of detection, A can send heartbeat packet to B, if A have received B sound
Should, and response signal is normal, then it represents that B is in normal condition, while D sends heartbeat packet to A, although A is sent to D
Heartbeat packet responded, but be in response to is error signal, such as normal response signal should be " 11 ", but A rings
The signal answered is " 01 ", then A responses are exactly error signal, now decides that A is online, but is in abnormality, also
It is that A is malfunctioning node gateway.
If the upstream node gateway of some node gateway is not online, then just without normal direction, the node gateway sends heartbeat
Bag, then the node gateway will be broadcasted in looped network, notify other non-faulting node gateways, the upstream node net of oneself
Close not online.
Step 102, the quantity of the malfunctioning node gateway is obtained；
When detect in looped network there is malfunctioning node gateway when, can be broadcasted in looped network.
For example, D detects A for malfunctioning node gateway, and malfunction is " equipment on-line, equipment is in abnormality ",
So, D can be broadcasted in looped network, and B, C are received after broadcast, be known that in looped network there is a malfunctioning node gateway, just
It is A, and malfunction is " equipment on-line, equipment is in abnormality ".If also there are other malfunctioning node nets in looped network
Close, then the upstream node gateway of the malfunctioning node gateway is broadcasted also by the above method in looped network, so, in looped network
Each non-faulting node gateway can learn in looped network that there are several malfunctioning node gateways, malfunctioning node gateway is which respectively
A bit, and, the malfunction of each malfunctioning node gateway.
Step 103, if the quantity of the malfunctioning node gateway is 1, the non-faulting node net being in from the looped network
The Central Shanxi Plain, determines starting point gateway and terminating gateway, and carry out data interaction between the starting point gateway and the terminating gateway；
If the node gateway of some in looped network occurs in that failure, then looped network is no longer just " ring ", looped network is also just paralysed
, it is that the main ring that will appear from failure is switched on standby ring, to ensure that looped network can be continued to run with the prior art.But such as
Now standby ring is also failure to fruit, then what looped network still can not normally be run, gently then causes looped network to be paralysed, heavy then cause ring
Loss of data in net in non-faulting node gateway.
, in embodiments of the present invention, can be from ring if the quantity of malfunctioning node gateway is 1 in order to avoid there is above-mentioned situation
In the non-faulting node gateway being in net, starting point gateway and terminating gateway are determined, and in starting point gateway and the terminating gateway
Between carry out data interaction.
In a kind of preferred embodiment of the invention, the non-faulting node gateway that normal condition is in from the looped network
In, determine starting point gateway and terminating gateway, and the progress data round-trip transmission between the starting point gateway and the terminating gateway
Including：
Using the upstream node gateway of the malfunctioning node gateway as starting point gateway, downstream node gateway is used as terminal net
Close, data interaction carried out between the starting point gateway and the terminating gateway,
Or,
Using the downstream node gateway of the malfunctioning node gateway as starting point gateway, upstream node gateway is used as terminal net
Close, data interaction carried out between the starting point gateway and the terminating gateway,
Or,
, will be except using the upstream node gateway of the malfunctioning node gateway, downstream node gateway simultaneously as starting point gateway
The malfunctioning node gateway, the upstream node gateway of the malfunctioning node gateway, the downstream node net of the malfunctioning node gateway
Any node gateway outside pass carries out data friendship as terminating gateway between the starting point gateway and the terminating gateway
Mutually.
For example, there is five node gateways of A, B, C, D, E in looped network, under normal circumstances, packet is according to A, B, C, D, E, A
Direction be transmitted, by detection learn A be malfunctioning node gateway, then in logic, what B, C, D, E were still linked in sequence,
Now can be using B as starting point gateway, then E carries out data biography as terminating gateway according to B, C, D, E, D, C, B, C order
It is defeated, during data transfer, it can continue to use " token ", to ensure that only one of which node gateway is in processing in link
Data；Can also be using E as starting point gateway, then B enters line number as terminating gateway according to E, D, C, B, C, D, E, D order
According to transmission.
, using C or D as terminating gateway, can also thus there are both links using B, E simultaneously as starting point gateway, than
Such as one link is B, C, and another link is E, D, C, or a link is B, C, D, and another link is E, D, then
In this case, it is exactly both links while carrying out data transmission.
Step 104, if the quantity of the malfunctioning node gateway is more than or equal to 2, and each malfunctioning node gateway is adjacent, then
From the looped network in the non-faulting node gateway in normal condition, starting point gateway and terminating gateway are determined, and at described
Data interaction is carried out between point gateway and the terminating gateway；
Specifically, in token-ring network, each node gateway has device id, and with uniqueness.Set up in looped network
The position relationship of each node gateway in Cheng Shi, looped network is just forever determined, and each node gateway is known that the upstream of oneself
Which platform node gateway is, which platform downstream node gateway is.
In this application, the state of looped network can be monitored from any one node gateway accessing computer in looped network,
Wherein, network management system is installed in computer.Webmaster can be by network management system to each node gateway transmission webmaster in looped network
Frame, so each node gateway just can know that the state of the node gateway of each in looped network, wherein, gateway frame is assisted using webmaster
View, in looped network, the highest priority of network management protocol.
For example, there is five node gateways of A, B, C, D, E in looped network, it is assumed that failure gateway is A, B, then webmaster passes through webmaster
System sends a webmaster frame, and such C, D, E are known that A, B are malfunctioning node gateway, Ran Hou after webmaster frame is received
Starting point gateway and terminating gateway are determined in C, D, E, and carries out between starting point gateway and terminating gateway data interaction.
In a kind of preferred embodiment of the invention, each node gateway is connected by optical fiber in the looped network, each node
Gateway has photoswitch respectively.
Photoswitch (Optical Switch, OS) is that one kind has one or more selectable transmission windows, can be to light
Optical signal in transmission line or integrated optical circuit carries out the device of mutually conversion or logical operation.The basic form of photoswitch is
2X2, that is, entering end and going out end respectively has two optical fiber, can complete two kinds of connection status, parallel connection and interconnection.Relatively large
Space division light crosspoint can be made up of basic 2X2 photoswitches and corresponding 1X2 optical switch stacks, combination.
Photoswitch plays highly important effect in optical-fiber network, in wavelength-division multiplex (Wavelength Division
Multiplexing, WDM) in Transmission system, photoswitch can be used for wavelength adaptation, regeneration and Clock Extraction, in Optical Time Division Multiplexing
In (Optical Time Division Multiplex, OTDM) system, photoswitch can be used for demultiplexing；In All-optical switching system
In system, photoswitch is optical cross connect (Optical Cross-connect, OXC) Primary Component, is also the weight of wavelength conversion
Want device.According to the input and output port number of photoswitch, can be divided into 1 × 1,1 × 2,1 × N, 2 × 2,2 × N, M × N etc. it is many
Kind, they have different purposes in different occasions.Its application mainly has：The pretection switch system of optical-fiber network, test optical fiber
In light source control, the real-time monitoring system of network performance, the test of optical device, build OXC equipment exchcange core, light insert/
Divide multiplexing, optic test, optical sensor system etc..
In this application, then it is pretection switch function using photoswitch, while malfunctioning node gateway opens photoswitch,
The data upstream and downstream switching congestion brought by this node failure or interruption are shielded, allows the upstream and downstream node of malfunctioning node to become direct
Believe that the node of neighbour carries out data interaction so that the upstream node gateway of malfunctioning node gateway can skip malfunctioning node gateway,
Downstream node gateway directly with malfunctioning node gateway carries out data interaction.
And the unlatching of photoswitch, both can be the photoswitch that webmaster opens malfunctioning node gateway by network management system,
When the working condition that can be photoswitch decision node gateway is abnormal condition, automatically turn on, wherein, photoswitch decision node
The working condition of gateway can be judged by encoding, for example, being encoded to 0000 during node gateway normal work, then light is opened
Pass detects when being encoded to 0000 of node gateway, would not open, if the coding detected is not 0000, then mean that
Node gateway is in abnormal operating state, then just automatically turns on.Certainly, other manner can also be used by opening photoswitch,
The embodiment of the present invention is not restricted to this.
For example, there is five node gateways of A, B, C, D, E in looped network, it is assumed that failure gateway is A, B, then webmaster passes through webmaster
System sends a webmaster frame, and such C, D, E are known that A, B are malfunctioning node gateways after webmaster frame is received, then, A,
Photoswitch in B is opened so that C, E turn into adjacent node gateway, then carry out data interaction.
It should be noted that when malfunctioning node gateway quantity is 1, and, the quantity of malfunctioning node gateway is more than or waited
In 2, and each malfunctioning node gateway it is adjacent when, except using aforesaid way ensure non-faulting node gateway between data interaction
Outside, the mode of photoswitch can also be used to ensure data interaction between non-faulting node gateway.
Step 105, if the quantity of the malfunctioning node gateway is more than or equal to 2, and each malfunctioning node gateway is non-adjacent,
Then skip each described malfunctioning node gateway and carry out data interaction.
For example, A, C are malfunctioning node gateway, but B is non-faulting node gateway, then must just be used using photoswitch
B can carry out data interaction with D, E, and because B is to be directly connected to D and E, the link of B, D, E composition is also looped network.
That is, original looped network has five node gateways of A, B, C, D, E, the order of data transfer is A, B, C, D, E, A, but is worked as
When A, C are malfunctioning node gateway, the node gateway of looped network is B, D, E, and the order of data transfer is B, D, E, B, node gateway A, C
It is equivalent to a link, no longer processing data, is only merely transmission data.
It is described to skip the step that each described malfunctioning node gateway carries out data interaction in a kind of preferred embodiment of the invention
Suddenly include：
Each described malfunctioning node gateway opens photoswitch and carries out data interaction.
Specifically, photoswitch can be with individual reception instruction and execute instruction.For example, when some node gateway is failure
During node gateway, the photoswitch of the malfunctioning node gateway can receive the transmission of non-faulting node gateway, open the finger of photoswitch
Order so that non-faulting node gateway can skip malfunctioning node gateway and proceed data interaction in looped network.
Reference picture 2, shows a kind of step flowchart 2 of the embodiment of the method for looped network self-healing of the present invention, specifically can be with
Comprise the following steps：
Step 201, the malfunctioning node gateway that abnormality is in the looped network is detected；
Step 202, the quantity of the malfunctioning node gateway is obtained；
Step 203, if the quantity of the malfunctioning node gateway is 1, the non-faulting node net being in from the looped network
The Central Shanxi Plain, determines starting point gateway and terminating gateway, and carry out data interaction between the starting point gateway and the terminating gateway；
Step 204, if the quantity of the malfunctioning node gateway is more than or equal to 2, and each malfunctioning node gateway is adjacent, then
From the looped network in the non-faulting node gateway in normal condition, starting point gateway and terminating gateway are determined, and at described
Data interaction is carried out between point gateway and the terminating gateway；
Step 205, if the quantity of the malfunctioning node gateway is more than or equal to 2, and each malfunctioning node gateway is non-adjacent,
Then skip each described malfunctioning node gateway and carry out data interaction；
Step 206, the malfunctioning node gateway is recovered automatically；The automatic recovery includes system reboot, recovers event
Normal operation before barrier is set；
In this application, node gateway has visual management system, and user can check section by connecting computer
The hardware state of point gateway, and, the working condition of looped network.So, in actual applications, it may appear that because system is unstable
Etc. factor, node gateway is caused to be in abnormality.Therefore, when detecting node gateway in abnormality, node gateway
The mode that can be set by restarting the normal operation before system, or recovery failure automatically is recovered.
Step 207, if automatic recover failure, fault warning is carried out；
When it is automatic recover failure when, then can be determined that the problem of not be management system, but node gateway hard in itself
Part problem, now, node gateway can carry out fault warning, and carry out failure logging.
Because being that in looped network, when some node gateway breaks down, all node gateways can in looped network
Learn, therefore, fault warning is not that can only be sent from malfunctioning node gateway, can also be sent from non-faulting node gateway.
Step 208, when the malfunctioning node gateway reverts to normal condition, and upstream node gateway, and, downstream joint
Point gateway carries out data interaction.
Whether through the mode recovered automatically, or the mode of hardware is changed, when malfunctioning node reverts to normal condition
When, it oneself can send broadcast or upstream or downstream node gateway sends broadcast, inform malfunctioning node gateway
