Embodiment one

A kind of jamming control method based on industry internet field layer device in the present embodiment, the field layer dress Put including stacked chips, the stacked chips include the first exchange chip, as shown in Figure 1A, the field layer device includes scene Bus protocol module, industrial flow control management module, isomery field devices integration module, the industrial flow control pipe Managing module is used for information monitoring and/or collection, and the information that will be monitored and/or gather is sent to the field bus communication agreement Module, the bus protocol module determines control strategy based on the information, and controls the isomery field devices integration mould Block forwards the relevant parameter with the control strategy, realizes the control to industry internet system relevant device, congestion control side Method includes step as shown in Figure 1：

Step 101：The information of the industrial flow control management module based on monitoring and/or collection determines that described first hands over The first priority query for changing first port in chip is in congestion state；

Step 102：The field bus communication protocol module is based on industrial flow control management module transfer really The first priority query of first port is in the information of congestion state, generation congestion control letter in fixed first exchange chip CCM is ceased, wherein, the CCM carries chip identification, the port-mark of the first port and the institute of first exchange chip The congestion information of the first priority query of first port is stated, first exchange chip includes at least one port, Mei Geduan Mouth corresponds at least one priority query；Based on the CCM, assembling congestion control frame CCF, the CCF include the CCM with And life span TTL, the TTL are for characterizing the number of times that the CCF can be forwarded；

Step 103：The field bus communication protocol module controls the isomery field devices integration module by the CCF The second exchange chip into the stacked chips is sent by stack port, to enable second exchange chip to be based on institute State the message that CCF stops dispatching the first priority query of the first port for being sent to first exchange chip.

Wherein it is determined that the first priority query of first port can be by as follows in congestion state in the first exchange chip Mode：

When assembling congestion control frame CCF, methods described also includes：Obtain the bandwidth of the stack port；Based on described The bandwidth of stack port, determines the transmission bandwidth of the CCF, wherein, the transmission bandwidth of the CCF is the band of the stack port Wide N/mono-, N is the integer more than 1.

Setting TTL initial value is needed in CCF, to limit the number of times that the CCF can be forwarded, so, in assembling congestion During control frame CCF, methods described also includes：Obtain the networking structure of the stacked chips；Based on the networking structure, institute is determined State TTL initial value.

Specifically, in the present embodiment, field layer device includes stacked chips, the stacked chips include the first exchange core QOS submodules in piece and the second exchange chip, the field bus communication protocol module of the field layer device are pre-configured with each end Mouthful priority query and judge priority query be in congestion state the first predetermined threshold value and recovery to non-congested shape Second predetermined threshold value of state, the first predetermined threshold value is more than the second predetermined threshold value.When the message flow for being dispatched to the priority query During more than the first predetermined threshold value, determine that the priority query is in congestion state, when the message flow for being dispatched to the priority query When amount is less than the second predetermined threshold value, determine that the priority query is in non-congested state.

Such as：First exchange chip has 32 ports, each 8 priority queries of port correspondence, each priority team Row are provided with corresponding predetermined threshold value.First port can be any one in 32 ports, it is assumed that first port is port 1, The port 1 of first exchange chip is configured with the queue that priority is 0~7, and the first priority query can be that priority is 0~7 In any one queue, it is assumed that the first priority query is the queue that priority is 0, and priority is corresponding pre- for 0 queue If threshold value is 10, the queue that the priority for detecting port 1 in QOS modules is 0 is dispatched to the queue in preset time range Message flow be 15, more than predetermined threshold value 10, the field bus communication protocol module of the field layer device of the first exchange chip Determine that the priority of port 1 is in congestion state for 0 queue, produce corresponding congestion control information CCM.And then can be based on The CCM, assembling generation CCF.In specific implementation process, priority query's number of each port configuration can be according to actual conditions Set, the corresponding predetermined threshold value of each priority query can also be set according to actual conditions, here, the application does not make Limit.

In order to be able to realize that the flow to the exchange chip during chip-stacked carries out accurate congestion control, the application is real Apply in example, devise a kind of congestion control CCF, the structure of the frame is as shown in Figure 2.Each in Fig. 2 domain is described as follows：

DMAC:Target MAC (Media Access Control) address, may be configured as fixed value 0xFFFFFFFFFFFF, take 6 bytes；

SMAC:Source MAC, occurrence can take 6 bytes by user configuring；

TYPE:Type of message, occurrence can take 2 bytes by user configuring；

TTL:Life span, for characterizing in the number of times that the CCF can be forwarded, CCF repeating process, often by a core Piece, the ttl value subtracts 1, takes 1 byte, and TTL initial value can be determined according to actual networking situation, such as：Stacked chips include 5 exchange chips, using the structure of ring-type networking, TTL initial value may be set to 2, and the CCF is forwarded 2 times can be by the CCF Propagate to 4 exchange chips of other in stacked chips.

Reserved：Retention, takes 5 bytes；

CCM:Congestion control information a, CCF includes N group CCM information, and N is the number of the priority query configured.Each CCM information identifies corresponding mask UID_MASK (3bit), exchange chip by exchange chip and identifies UID (User Identification) (5bit) and congestion information CCI (Congestion Control Information) compositions (32bit).Wherein, UID is the chip identification in actual network environment, for distinguishing the different chips in network, shows the CCM Affiliated chip.UID_MASK can be used for some of shielding UID bit (1：Shield bit0；2：Shield bit1~bit0；3：Screen Cover bit2~bit0；4：Shield bit3~bit0；0：All bit are effective；5~7：reserved).CCI carries 32 ports Congestion information, each bit carries the congestion information of a port, and bit is 1 to represent port congestion, and bit is 0 to represent port not Congestion.What the 0th group of CCM in CCF was carried is the 1st group of CCM carryings in the congestion information for 32 ports that priority is 0, CCF When priority for 1 32 ports congestion information, by that analogy, a CCF carries 32 ports of N number of priority altogether Congestion information.

Frame check code FCS (Frame Check Sequence):Take 4 bytes.

Further, when being transmitted due to CCF in stack port, the transmission belt of normal data message can be taken It is wide.Limitation CCF transmission bandwidth is needed, in the present embodiment, the corresponding transmission bandwidths of CCF are the default of the bandwidth of stack port Multiple, such as, CCF transmission bandwidth can be limited to the 1/10 bandwidth limitation CCF of stack port bandwidth, certainly, CCF biography Defeated bandwidth can be set according to the actual requirements, here, the application is not limited.So, it is possible to prevente effectively from because of CCF transmission The bandwidth of more stack port is taken, causes the problem of normal message transmission is limited.

In specific implementation process, field bus communication protocol module it is determined that the first exchange chip first port When one priority query is in congestion state, the first priority query of first port is indicated according to above-mentioned CCM form generation CCM in congestion state, and then, generated by above-mentioned CCF forms after CCF, the field bus communication protocol module controls institute State isomery field devices integration module and the CCF is sent into other exchange chips into stacked chips by stack port, such as：The Two exchange chips, and then when the second exchange chip receives the CCF, field bus communication protocol module extracts the CCF first TTL, it is determined that TTL value be more than 0 when, the CCF is parsed.

The field bus communication protocol module of layer device is parsed to the CCF transmitted to the second exchange chip at the scene When, the CCM in CCF is extracted, CCI and UID in CCM is obtained, and then according to UID and CCI, the first exchange chip can be known First priority query of first port is in congestion state.Such as：First exchange chip includes 32 ports, each port pair 8 priority queries are answered, when the priority of port 1 is in congestion state for 0 queue, the corresponding flag bit in port 1 is set to Position is 1, shows that congestion occurs in port 1, and the corresponding priority in port 1 is also set to 1 for the flag bit of 0 queue, shows Occur congestion in port 1 is the queue that priority is 0.Second exchange chip determines that the first exchange chip goes out by reading UID Existing congestion, it is 1 to read the corresponding flag bit in port 1, determines that congestion, 1 pair of read port occurs in the port 1 of the first exchange chip The flag bit for the queue that the priority answered is 0 is 1, you can the corresponding priority in port 1 for determining the first exchange chip is 0 team Row are in congestion, and then, field bus communication protocol module controls the second exchange chip to stop scheduling and is sent to the first exchange chip The corresponding priority in port 1 for 0 queue message.

In order to more fully understand the jamming control method in the present embodiment, it is given below one and complete is applied to heap The example of the jamming control method of the field layer device of the first exchange chip in folded chip.

Multi-chip stacking networking scene constitutes loop network as shown in figure 3, five exchange chips are stacked.Every friendship Chip is changed using two stack ports of A, B with other two exchange chips to be connected.By taking exchange chip 5 as an example, to use congestion control Function processed, need to do following configuration：

It is 2 to set the ttl value that the UID values of exchange chip 5 are 5, CCF, and CCF can be made to be delivered to exchange chip 3 and exchange Transmission is not continued to after chip 1, prevents CCF from circulating in the loop；It is 0xFFFFFFFFFFFF, fixed value to set DMAC values；If SMAC values are put for 0x0180C2000000, the value can be configured by user flexibility.

Assuming that the priority of the common port 0 of exchange chip 5 is blocked for 0 message, the biographies of CCF in a network are produced Broadcast flow as follows：

Exchange chip 5 transmits CCF respectively by stack port A and B.

Exchange chip 4 is received after CCF, and the field bus communication protocol module of field layer device, which is detected, to be transmitted to exchange The CCF of chip 4 ttl value is 2, then extracts the CCM in CCF, CCM is sent into dispatching management module, exchange is known based on CCM The priority of the port 0 of chip 5 is blocked for 0 message, and then stops the end that dispatching exchange chip 4 is sent to exchange chip 5 The priority of mouth 0 is 0 message, then subtracts 1 by ttl value, the TTL field in modification CCF, and CCF is forwarded into exchange chip 3.

Exchange chip 3 is received after CCF, and the field bus communication protocol module of field layer device, which is detected, to be transmitted to exchange The CCF of chip 3 ttl value is 1, then extracts the CCM in CCF, CCM is sent into dispatching management module, exchange is known based on CCM The priority of the port 0 of chip 5 is blocked for 0 message, and then stops dispatching exchange chip 3 toward the port 0 of exchange chip 5 Priority be 0 message.Because ttl value is 1, exchange chip 3 will not be forwarded CCF to next chips exchange chip 1.

Similarly, exchange chip 2 is received after CCF, and the field bus communication protocol module of field layer device detects transmission Ttl value to exchange chip 2 is 2, then extracts the CCM in CCF, CCM is sent into dispatching management module, friendship is known based on CCM The priority for changing the port 0 of chip 5 is blocked for 0 message, and then stopping dispatching exchange chip 2 is sent to exchange chip 5 The priority of port 0 is 0 message, then subtracts 1 by ttl value, the TTL field in modification CCF, and CCF is forwarded into exchange chip 1.

Exchange chip 1 is received after CCF, and the field bus communication protocol module of field layer device, which is detected, to be transmitted to exchange The CCF of chip 1 ttl value is 1, then extracts the CCM in CCF, CCM is sent into dispatching management module, exchange is known based on CCM The priority of the port 0 of chip 5 is blocked for 0 message, and then stops dispatching exchange chip 1 toward the port 0 of exchange chip 5 Priority be 0 message, because ttl value is 1, exchange chip 1 will not be forwarded CCF to next chips exchange chip 3.

And then, it is not that obstruction is sent to this chip port when for 0 congestion is occurring for the priority of the port 0 of exchange chip 5 Other chips (including chip 0 itself) are sent to the preferential of the port 0 of exchange chip 5 in 0 all flows, only stream control stacked chips Level is the flow of 0 queue, and being sent to the priority of the port 0 of exchange chip 5 can normally send for 1~7 flow.

So, the jamming control method in the present embodiment can carry out congestion control based on port, priority, effectively solve The irrational technical problem of congestion control in the prior art to the exchange chip in stacked chips, is realized more flexibly and essence Really flow is controlled, bandwidth resources is utilized.

Further, in order to when the message in queue is scheduled, be only scheduled to complete message, it is ensured that message Continuity, accurate control has initiated dispatch request but has not completed the quantity for the Cell for actually going out team also, reduction cache resources Consumption, in the present embodiment, the queue of each port is as shown in Figure 4 in exchange chip.Some messages are included in queue, and it is each Some Cell (element) are included in individual message.Tail pointer is used to point to the Cell of last in queue in queue.Message tail pointer Last Cell for pointing to the complete message of last in queue.Scheduling head pointer is used to point to newest initiation request tune The Cell of degree.Going out group head pointer is used to point to last Cell for completing scheduling.Dispatching message head pointer is used to point to one First Cell of message.So, exchange chip can just use the queue in the embodiment of the present application, in subsequent steps, Message is dispatched accordingly.

In the embodiment of the present application, exchange chip is as follows to the scheduling idiographic flow of message：

The state of joining the team of queue is monitored, it is determined that when the state representation message of joining the team is joined the team, to the message trailer of the queue Pointer is updated, wherein, the message tail pointer is used to pointing to last of last complete message in the queue Unit Cell；

Calculate the scheduling head pointer of the queue and go out the difference of group head pointer, obtain scheduling difference, wherein, the scheduling Head pointer be used for point to current request scheduling Cell, it is described go out group head pointer be used for point to last complete scheduling Cell；

Determine that the scheduling difference is less than predetermined threshold value, and the scheduling head pointer is less than the message tail pointer When, the message in the queue is scheduled.

Specifically, the scheduler module in exchange chip monitors the state of joining the team of queue, it is determined that state representation message of joining the team enters During team, the tail pointer of queue is updated, wherein, tail pointer is used to point to the Cell of last in queue.Then, tail is obtained The first description information for the Cell that pointer is pointed to, and based on the first description information, determine that the Cell that tail pointer is pointed to is a report During last Cell of text, message tail pointer is pointed into the Cell that tail pointer is pointed to.In this manner it is possible to be determined by tail pointer Last Cell in queue, and the complete message of last in queue is determined by message tail pointer, so that follow-up Dispatching message during, only complete message can be scheduled by message tail pointer.

And then, exchange chip can be according to the scheduling difference of acquisition, and when subsequently initiating dispatch request, accurate control is Initiate dispatch request but do not complete the quantity for the Cell for actually going out team also, so as to reduce the consumption of cache resources.

Finally, exchange chip determines that scheduling difference is less than predetermined threshold value, and dispatches head pointer less than message tail pointer When, based on scheduling head pointer, it is determined that the Cell that head pointer is pointed to is dispatched, as the first Cell, and to the next of the first Cell Cell initiates dispatch request, and scheduling head pointer is updated, and points to the first Cell next Cell.Then, exchange Chip is based on out group head pointer, determines the Cell that group head pointer is pointed to, as the 2nd Cell, and determines that the 2nd Cell's is next When individual Cell completes scheduling, group head pointer will be gone out and be updated, point to the 2nd Cell next Cell.Then, exchange chip Based on group head pointer is gone out after the scheduling head pointer after renewal or/and renewal, the message in queue is scheduled.So, hand over Group Cell of head pointer sensing can will just be gone out to each Cell dispatched between the Cell that head pointer is pointed to by changing chip, be entered successively Row goes out team, completes scheduling.

In the embodiment of the present application, last complete message of queue is determined by message tail pointer, so as to only right Complete message is scheduled, it is ensured that the continuity of message, and the scheduling head pointer by queue and the difference for going out group head pointer Value, can accurately control to have initiated dispatch request but not complete the quantity for the Cell for actually going out team also, so as to reduce caching The consumption of resource.
