Wherein, the physical layer block in the embodiment of the invention is that the bus of media independent class is converted to electricity mouthful class bus (as netting twine) or light mouth class bus (as optical fiber), also finishes a class chip of the encoding function of transmission signals simultaneously.
Central processing module in the embodiment of the invention can be central processing unit (CPU) chip, and and other processor of ether function can be provided.
The port of the embodiment of the invention includes but not limited to a kind of in the following port:
Ethernet port (such as 10/100M port, GE port, 10GE port etc.) and optical fiber interface.
As shown in Figure 1, the equipment of embodiment of the invention detection port comprises: physical layer block 10 and central processing module 20.
Physical layer block 10 is used to judge whether port breaks down, and physical layer block sends the connection failure index signal to central processing module after definite port breaks down, be used to notify central processing module 20 ports to break down.
Central processing module 20 is used to receive the connection failure index signal.
Wherein, physical layer block 10 determines that port breaks down when loss of link.
Concrete, when loss of link, the buffer status of physical layer block chip 10 inside can change automatically.That is to say, during the register state change of physical layer block chip 10 inside, just know loss of link.
In specific implementation process, physical layer block 10 can be an interrupt signal to the connection failure index signal that central processing module 20 sends, and can also be that other can represent the port out of order signal.
No matter the communication media of physical layer is twisted-pair cable or optical fiber, and when loss of link, physical layer block 10 can both send the connection failure index signal.
Afterwards will send the connection failure index signal within the 1ms because physical layer block 10 breaks down at definite port, thereby shorten the time that central processing module 20 is known port failure, have good real-time performance.
Wherein, central processing module 20 carries out the port handover operation after receiving the connection failure index signal.
Concrete, the link that central processing module 20 will be connected with the port that breaks down switches on the normal port.
Such as central processing module 20 after receiving the connection failure index signal, interruption is also preserved current program, carries out the port changeover program, the open failure port, data source is finished corresponding mapping relations with the normal port of communication, continue to send business packet by normal port.
In specific implementation process, because each physical layer block 10 has one-to-one relationship with outside port, so central processing module 20 can be according to determining that in the physical layer block 10 that sends the connection failure index signal which port breaks down.
A kind of preferable mode is: adopt the method for port priority dynamic assignment to carry out failover.
Concrete, central processing module 20 pre-determines each port corresponding priorities, and select the highest port of priority to transmit, after receiving the connection failure index signal, the priority of cancellation non-working port, determine current each port corresponding priorities, and switch to the highest port of current priority.
Suppose to have three ports, at a time, the priority of A port is 1, and the priority of B port is 2, and the priority of C port is 3.Here regulation is preferentially used the priority number junior, promptly adopts the A port to give out a contract for a project this moment, and B port and C port are in idle condition.When central processing unit module 20 receives that the interruption (link lose etc.) of A port triggers, can be with the priority level cancellation of A port, and be labeled as non-working port, all priority that are in the port of idle condition numerically subtract one simultaneously, the priority that is the B port becomes 1 by 2, the priority of C port becomes 2 by 3, and then central processing module 20 adopts the B port to give out a contract for a project according to current priority level decision again.
Further, central processing module 20 is after the port that breaks down recovers normally, and the priority of the port after recovery is normal is set to minimum.
Priority such as the A port is 1, and the priority of B port is 2, and the priority of C port is 3, and behind the A port failure, the priority of B port is 3, and the priority of C port is 2.The A port recover normal after, the faulty tag of A port is removed, the priority of A port is composed and is lowest priority in front port, promptly the A port priority is 3.
Need to prove, top priority 3,2 and 1 just illustrates scheme, in force, can stipulate that 3 is limit priorities, also can be not limited to numeral, letter waits other modes that can represent priority also to be suitable for the embodiment of the invention, and also can not carry out the numerical value plus-minus, after recovering normally, port can increase the expression mode of a lowest priority, such as two port prioritys is respectively A and B, behind the port failure of priority A, can keep priority B, after the port of priority A recovered normally, revising priority was that C gets final product.
Wherein, central processing module 20 can also be determined the fault type of the port that breaks down after receiving the connection failure indication letter, and notifies the upper strata to handle fault type.
Concrete, central processing module 20 reads the buffer status in the physical layer block 10 after receiving the connection failure indication letter, and determines corresponding fault type according to buffer status.
Because every kind of possible fault type all has definition in physical layer block 10, as long as the malfunction register in the inquiry physical layer block 10.
If central processing module 20 determines that according to fault type this fault upper strata can't repair (come off such as port etc.), then can notification gateway handle, such as modes such as sound and light alarms.
As shown in Figure 2, in the schematic diagram of embodiment of the invention port switching, central processing module 20 is on the data processing plate, be connected with two physical layer block 10 by two Media Independent Interfaces respectively, and send data to physical layer block 10 by Media Independent Interface, the physical layer block 10 that is connected with the RJ45 port sends by the RJ45 port after receiving data, and the physical layer block 10 that is connected with fiber port sends by fiber port after receiving data.
If RJ45 port failure, the physical layer block 10 that then is connected with the RJ45 port can send interrupt signal to central processing module 20, central processing module 20 can carry out handover operation to this port, will with the data source of this port mapping, on other normal ports of mapping end.
The state that central processing module 20 can be checked register in the physical layer block 10 by management interface from, determine according to the state of register whether fault type and failure judgement are eliminated.
As shown in Figure 3, the method for embodiment of the invention detection port comprises the following steps:
Step 301, physical layer block judge whether port breaks down.
Step 302, physical layer block send the connection failure index signal to central processing module after definite port breaks down, be used to notify the central processing module port to break down.
In the step 301, whether physical layer block can lose according to link, determines whether port breaks down, and when loss of link, determines that port breaks down.
Concrete, when loss of link, the buffer status of physical layer block chip 10 inside can change automatically.That is to say, during the register state change of physical layer block chip 10 inside, just know loss of link.
In specific implementation process, in the step 302, physical layer block can be an interrupt signal to the connection failure index signal that central processing module sends, and can also be that other can represent the port out of order signal.
Afterwards will send the connection failure index signal within the 1ms because physical layer block breaks down at definite port, thereby shorten the time that central processing module is known port failure, have good real-time performance.
Wherein, can further include after the step 302:
Step 303, central processing module carry out the port handover operation after receiving the connection failure index signal.
Concrete, in the step 303, the link that central processing module will be connected with the port that breaks down switches on the normal port.
Such as central processing module after receiving the connection failure index signal, interruption is also preserved current program, carries out the port changeover program, the open failure port, data source is finished corresponding mapping relations with the normal port of communication, continue to send business packet by normal port.
In specific implementation process, because each physical layer block and outside port have one-to-one relationship, so central processing module can be according to determining that in the physical layer block that sends the connection failure index signal which port breaks down.
A kind of preferable mode is: adopt the method for port priority dynamic assignment to carry out failover.
Concrete, central processing module pre-determines each port corresponding priorities, and select the highest port of priority to transmit, after receiving the connection failure index signal, the priority of cancellation non-working port, determine current each port corresponding priorities, and switch to the highest port of current priority.
Suppose to have three ports, at a time, the priority of A port is 1, and the priority of B port is 2, and the priority of C port is 3.Here regulation is preferentially used the priority number junior, promptly adopts the A port to give out a contract for a project this moment, and B port and C port are in idle condition.When central processing unit module 20 receives that the interruption (link lose etc.) of A port triggers, can be with the priority level cancellation of A port, and be labeled as non-working port, all priority that are in the port of idle condition numerically subtract one simultaneously, the priority that is the B port becomes 1 by 2, the priority of C port becomes 2 by 3, and then central processing module 20 adopts the B port to give out a contract for a project according to current priority level decision again.
Further, central processing module is after the port that breaks down recovers normally, and the priority of the port after recovery is normal is set to minimum.
Priority such as the A port is 1, and the priority of B port is 2, and the priority of C port is 3, and behind the A port failure, the priority of B port is 3, and the priority of C port is 2.The A port recover normal after, the faulty tag of A port is removed, the priority of A port is composed and is lowest priority in front port, promptly the A port priority is 3.
Need to prove, top priority 3,2 and 1 just illustrates scheme, in force, can stipulate that 3 is limit priorities, also can be not limited to numeral, letter waits other modes that can represent priority also to be suitable for the embodiment of the invention, and also can not carry out the numerical value plus-minus, after recovering normally, port can increase the expression mode of a lowest priority, such as two port prioritys is respectively A and B, behind the port failure of priority A, can keep priority B, after the port of priority A recovered normally, revising priority was that C gets final product.
In the step 303, central processing module can also be determined the fault type of the port that breaks down after receiving the connection failure indication letter, and notifies the upper strata to handle fault type.
Concrete, central processing module reads the buffer status in the physical layer block after receiving the connection failure indication letter, and determines corresponding fault type according to buffer status.
If central processing module determines that according to fault type this fault upper strata can't repair (come off such as port etc.), then can notification gateway handle.
As shown in Figure 4, the method for embodiment of the invention port switching comprises the following steps:
Step 401, central processing module initialization port priority, the priority of A port is 1, and the priority of B port is 2, and the priority of C port is 3.
Step 402, central processing module are according to the priority assignment port status, and the A port is to use state, and B port and C port are idle conditions, and central processing module sends packet by the A port.
Step 403, the physical layer block that is connected with the port of user mode judge whether the link of this port connection is normal, if, then continue to judge, otherwise execution in step 404.
The port of the user mode here is the A port.
Whether just detect the link that is connected with the port of user mode after wherein, physical layer block can become user mode at the state of port normal.That is to say, step 403 sends packet with central processing module by the A port does not have inevitable order, promptly can carry out central processing module sends packet by the A port step earlier, execution in step 403 again, also can first execution in step 403 carry out the step of central processing module again, can also carry out central processing module sends packet by the A port step and step 403 simultaneously by A port transmission packet.
Certainly, if do not have to need to pass through the packet that the A port sends, also can not carry out central processing module sends packet by the A port step.
Step 404, physical layer block send interrupt signal to central processing unit.
Step 405, central processing module change the priority of each port, and mark A port failure, and the B port priority after the change is 1, and the C port priority is 2.
Step 406, central processing module are according to the priority assignment port status, and the B port is to use state, the C port, and will switch to by the B port by the packet that the A port sends and send.
Because the port of user mode becomes the B port, so when turning back to step 403 after the step 406, the executive agent in the step 403 becomes the physical layer block that is connected with the B port.
Because the B port is to use state, so physical layer block will detect the link that is connected with the B port.
Step 407, central processing module notify the upper strata to handle fault type.
Wherein, step 407 can be carried out between step 404 and step 405.
Step 408, central processing module are removed the faulty tag of A port after the link failure of determining to break down is eliminated, and the priority of A port is arranged to lowest priority in front port.
If fault can't be eliminated by software, tell the plant maintenance personnel to handle by modes such as outside audible and visual alarms.If fault can be eliminated by software, then after troubleshooting, inquire about the state of physical layer block again, after confirming that fault has been eliminated, the faulty tag of A port is removed, the priority of A port is arranged to lowest priority in front port.
From the foregoing description as can be seen: embodiment of the invention physical layer block judges whether port breaks down; Physical layer block sends the connection failure index signal to central processing module after definite port breaks down, be used to notify the central processing module port to break down.
Because by physical layer block detection port fault whether, and when fault, send the connection failure index signal, do not need to take effective bandwidth, thereby improved bandwidth availability ratio, and physical layer block is detecting port failure and is sending time of connection failure index signal very short, has good real-time performance.
