Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for adaptive information transparent transmission, including:
s100, the first manufacturer equipment sends information to the second manufacturer equipment through a regeneration mode;
s200, after receiving information sent by first manufacturer equipment, first equipment of a second manufacturer forwards the information to other equipment of the second manufacturer in a transparent transmission mode and forwards the information to other equipment of the first manufacturer through the other equipment of the second manufacturer, so that information interaction between the first manufacturer equipment is completed;
and S300, increasing or reducing flag bytes in the interactive information according to the chip FIFO water level when information interaction is carried out between the second manufacturer equipment and the first manufacturer equipment so as to ensure that the chip FIFO works normally.
It should be noted that the present embodiment is used for implementing the interaction between the same-plant devices separated by different-plant devices through the different-plant devices. As shown in fig. 2, the equipment in the plant a and the equipment in the plant B are different plants, and the embodiment of the present invention is applicable to a scenario when the equipment in the plant a 1 needs to interact with the equipment in the plant a 2 through the equipment in the plant B.
It should be noted that the regeneration mode described in S100 refers to a process in which received information (such as management information in OTN overhead) needs to be converted into an HDLC frame through an HDLC protocol (High Level Data Link Control, bit-oriented synchronization protocol) and then is subsequently processed, or the HDLC frame after information receiving processing is reversely converted into information to be sent through the HDLC protocol, that is, the regeneration mode needs to be converted through the HDLC protocol or reversely converted. The transparent transmission mode adopted in S200 is a mode in which received HDLC frame information is composed into an ethernet frame and is sent by unicast through a backplane or HDLC frame information is extracted from the ethernet frame received by the backplane and is directly mapped to an OTUk frame, that is, the transparent transmission mode does not need to be converted by an HDLC protocol or a reverse conversion process.
It should be noted that the flag byte described in S300 refers to a plurality of flag bytes 0x7E added during the process of converting HDLC frames through the HDLC protocol in the regeneration mode, and is used to ensure the continuity of the management information in the OTN overhead.
It can be understood that, because the backplane needs to forward the ethernet packet, the inter-plant device in the middle needs at least two or more than two applicable scenarios in this embodiment. When intermediate transmission needs to be performed through multiple devices of different plants, for example, a plant device 1 a needs to perform an interactive scenario with a plant device 2 a through a plant device B, and more than two devices exist in a plant device B, for example, the plant device 1B, the plant device 2B, the plant device 3B, and the like, for the scenario, it is necessary to adjust a flag byte through a chip FIFO water level when the plant device B interacts with the plant device 1 a or the plant device 2 a in S300, and thus, it is ensured that the chip FIFO normally operates. As for the interaction between the B plant equipment and the B plant equipment in the middle process, if the B plant equipment and the B plant equipment on two sides are the same group of clock sources, the problem of frequency deviation does not exist, the water level of the chip FIFO does not change, and therefore the flag byte does not need to be adjusted through the water level of the chip FIFO; if the clock source is not the same as the clock source of the B-factory devices on the two sides, a certain frequency offset exists, and the flag byte can be adjusted through the water level of the chip FIFO to ensure that the chip FIFO works normally.
The embodiment of the invention aims at the problem of information loss caused by certain frequency offset existing in the intercommunication of devices of different factories under the condition that the devices of the same factory with the devices of different factories at intervals are interacted, and ensures that the information is not lost during transparent transmission by increasing or reducing the flag bytes in the automatically adjusted information.
In some embodiments, further comprising the step of:
s400, when information interaction is carried out between the second factory equipment, the corresponding relation between the back plate side Ethernet message and the line side optical port channel is determined by configuring the MAC address in the back plate side Ethernet message and the VLAN register of the line side optical port channel.
It should be noted that, because the second manufacturer devices interact in a transparent transmission mode, the function of flexibly mapping management information transparent transmission in the multi-channel OTN overhead is supported by the advantage that the VLAN in the backplane-side ethernet frame can be configured and the FPGA module can be reused.
In some embodiments, S100 comprises the steps of:
s110, first equipment of a first manufacturer extracts PPP frames with certain frame length from each group of Ethernet frames of received information;
s120, adding a plurality of flag bytes 0x7E between every two groups of PPP frames with certain frame length;
s130, converting the PPP frame into an HDLC frame through HDLC protocol processing;
and S140, mapping the HDLC frame to form an OTUk frame and sending the OTUk frame to the first equipment of the second manufacturer.
In some embodiments, S200 includes the steps of:
and S210, the first equipment of the second manufacturer extracts HDLC frame information from the OTUk frame through demapping and forms an Ethernet frame, and the Ethernet frame is unicast sent to the second equipment of the second manufacturer through a backboard.
Further, S200 further includes the steps of:
and S220, extracting HDLC frame information from the Ethernet frame received by the backboard by the second equipment of the second manufacturer, mapping the HDLC frame information to form an OTUk frame, and sending the OTUk frame to the other equipment of the first manufacturer.
In some embodiments, the step of S220 is followed by the step of:
s230: another device of the first manufacturer extracts HDLC frame information from the received OTUk frame through de-mapping and restores the HDLC frame information into a PPP frame after reverse processing of an HDLC protocol;
s240, the restored PPP frames are combined into Ethernet frames.
It should be noted that, after the restored PPP frames are combined into ethernet frames in S240, the information may be sent to the master control disk device from the backplane side, and then the network manager extracts useful information for use.
Further, when the HDLC protocol is reversely processed in S230 and then restored to the PPP frame, the byte in the HDLC frame is detected, and if the detected byte is not the flag byte 0x7E, the HDLC protocol is reversely processed.
It can be understood that after detecting the continuous flag byte 0x7E, the first message with non-0 x7E content is detected, that is, the header of the message, and the reverse processing of the HDLC protocol can be started when recognizing the header of the message.
In some embodiments, the step S300 of automatically adjusting the flag bytes in the interactive information to increase or decrease according to the chip FIFO level of the second factory device includes the steps of:
s310, the first equipment of a second manufacturer receives the OTUk frame information sent by the first manufacturer equipment, extracts HDLC frame information through demapping, and forms an Ethernet frame to be sent to the second equipment of the second manufacturer through a backboard in a unicast mode;
s320, when the water level of the chip FIFO of the second factory equipment exceeds a preset maximum threshold value, reducing the flag byte 0x7E in the HDLC frame information;
s330, when the chip FIFO water level of the second factory equipment is lower than a preset minimum threshold, increasing a flag byte 0x7E in the HDLC frame information.
In a second aspect, an embodiment of the present invention further provides an apparatus, where the apparatus includes: at least one processor; and a memory coupled to the at least one processor, the memory containing instructions stored therein which, when loaded and executed by the processor, perform a method according to any of the method embodiments.
As shown in fig. 2, in a specific embodiment, the plant equipment 1 a of the site 1 needs to communicate with the plant equipment 2 a of the site 3 through the plant equipment B of the site 2, and the following adaptive information transparent transmission method may be adopted, including:
s1, setting the A plant equipment 1 of a site 1 to be in a regeneration mode, extracting a PPP frame from an Ethernet frame which is received by a backboard and contains management information in OTN overhead, converting the PPP frame into an HDLC frame through HDLC protocol processing, mapping the HDLC frame to form an OTUk frame, and sending the OTUk frame to the B plant equipment 1 of the site 2 by the A plant equipment 1;
the HDLC protocol processing can be understood as adding a plurality of flag bytes 0x7E between every two sets of PPP frames with certain frame length to ensure the continuity of management information in OTN overhead, then performing HDLC protocol conversion on the frame content of the PPP frames, and inserting 0 of 1 bit after 5 bits as long as 5 bits of the PPP frames are detected as 1, so as to ensure that the flag bytes 0x7E do not appear in the frame content of the HDLC frames after the HDLC protocol conversion. It can be understood that 0x7E is binary "01111110", that is, 6 "1" s are inserted when 5 "1" s are detected, and then the frame content of the PPP frame is processed by the HDLC protocol, and then 6 "1" s are not present.
S2, setting the B plant equipment 1 of the site 2 to be in a transparent transmission mode, demapping and extracting HDLC frame information from the OTUk frame sent by the A plant equipment 1 by the B plant equipment 1 to form an Ethernet frame, and sending the Ethernet frame to the B plant equipment 2 of the same site 2 through a backboard in a unicast mode;
it can be understood that, since the HDLC frame is not processed by the protocol, the frame content is completely transmitted to the B plant device 2 at the same site 2.
S3, setting the B plant equipment 2 of the site 2 to be in a transparent transmission mode, and after receiving the Ethernet frames sent by the B plant equipment 1 from the backboard, the B plant equipment 2 extracts HDLC frame information from the Ethernet frames and forms OTUk frames through mapping to be sent to the A plant equipment 2 of the site 3; the HDLC frame is not processed by the protocol, and the frame content is completely transmitted to the a-plant device 2 at the site 3.
And S4, setting the A plant equipment 2 of the site 3 to be in a regeneration mode, after receiving the OTUk frame sent by the B plant equipment 2, the A plant equipment 2 demaps and extracts HDLC frame information from the OTUk frame, and the HDLC frame information is restored to be a PPP frame after being reversely processed by an HDLC protocol.
It can be understood that, during the reverse processing of the HDLC protocol, the header position of the packet is identified by detecting the flag byte 0x7E in the HDLC frame, when it is detected that the flag byte is not 0x7E, the reverse processing of the HDLC protocol is started, and if it is detected that 5 consecutive bits are 1, 0 of 1 bit is deleted afterwards, thereby implementing the frame content restoring function of the PPP frame. And stopping the reverse processing of the HDLC protocol until the message has the flag byte 0x7E again. The operation can be repeated in sequence aiming at a plurality of received HDLC frames, and then the restored PPP frames are combined into Ethernet frames to be sent out from the backboard.
Preferably, as shown in fig. 2, when considering that the three clock domains have a certain frequency offset, the clock domain CLK1 of the a plant equipment 1 of the site 1, the clock domain CLK2 of the B plant equipment 1 and the B plant equipment 2 of the site 2, and the clock domain CLK3 of the a plant equipment 2 of the site 3 may cause the management information in the OTN overhead to be lost in the equipment of different sites if not processed, so that when information interaction is performed between the B plant equipment 1 of the site 2 and the B plant equipment 2, the management information in the OTN overhead is not lost even when the clock domains have a certain frequency offset by using a mode that the chip FIFO level automatic adjustment flag byte 0x7E is increased or decreased.
Preferably, by using the advantages of VLAN configurability and FPGA module reusability in the backplane side ethernet frame, the corresponding relationship between the backplane side ethernet packet and the line side optical port channel is realized by configuring registers such as the MAC address and the channel VLAN in the backplane side ethernet packet, thereby realizing the flexible mapping function of the transparent transmission channel.
