Embodiment
Can to cause backboard to sidle line for the too much situation in backboard groove position too much in view of special-purpose HW bus run, present embodiment proposes the notion of a kind of soft HW, main thought is to simulate a designated lane in management channels, rather than set up the promptness that information such as a passage guarantees to alarm and switch are transmitted on the hardware separately, both save backboard side line road, reached the effect of specialized high-speed passage again.
The implementation of soft HW bus for example can adopt and add the priority treatment mark in the message of encapsulation emergence message, realizes transmitting fast between plate alarm, expense, heartbeat and switches emergence message such as control.This scheme does not need to increase each business board to the line between the master control borad, but utilize existing management channels between master control borad and the business board, can be FE, GE etc., by the message that carries emergence message is carried out mark, construct, send, receive and resolve the message of tape label by hardware such as programmable logic device, realize fast processing alarm, expense, heartbeat and switch emergence message such as control.Programmable logic device can adopt as field programmable gate array (Field Programmable Gate Array, FPGA) etc.
Present embodiment is by carrying out the purpose that mark reaches emulation HW line to message, realizes between plate alarm, expense, heartbeat and switches emergence message such as control, transmits fast by inner ethernet management passage.For example, can in carrying the message of emergence message, add the VLAN(VLAN) label, realize alarm, expense, heartbeat and switch the quick transmission of information between plate such as control by adding VLAN.
Message is carried out mark realize emulation HW line, be to be responsible for structure, transmission, reception and analytic message by FPGA, make full use of FPGA with respect to CPU in the superiority aspect the control in real time, do not increase the weight of that CPU on business board and the master control borad handles and the burden of analytic message.Alarm, expense, heartbeat and switch time of the transmission cost of emergence message such as control, depend primarily on the time of FPGA structure, transmission, reception and analytic message, these times are generally in the scope of tens to tens microseconds, therefore can ignore, so can reach the effect of special-purpose HW bus.
Chip-stacked (also claiming chip cascade) be with two or two above chips by high-speed channel interconnected (needing the cooperation of communication packet form or communications protocol sometimes), realize multiple chips is modeled to the effect of a chips.
The original intention of chip-stacked generation is in order to increase chip capacity and interface quantity, thus the function of expensive chip.In the present embodiment, the chip more than two or two with being positioned over respectively on the different master control borads is modeled to a chips, and main purpose is not the increase capacity, but realizes that protection is switched fast.Because different chips is placed on the different veneers, just being equivalent to active and standby after chip stack builds up one is a veneer with master control borad, and active and standby information interaction with two or multiple chips on the master control borad has been modeled to the information transmission between each port of a chips.Speed is faster aspect information synchronization like this, on the one hand; Switching rate when switching generation also can be faster on the other hand.
Adopt chip-stackedly in the present embodiment between the master control borad, adopt soft HW between master control borad and the business board, thereby set up the data passes passage of a complete closure.Each part in the whole passage can both guarantee the highest efficient, and whole system is simple, is easy to realize.
Below in conjunction with accompanying drawing present embodiment is elaborated.

As shown in Figure 3, present embodiment on the business board direction, realizes the method for communication between veneer from master control borad, comprising:
For example, the filling mode of 4 bytes of VLAN is TPID(tag protocol identifier): the 0x8100(VLAN specific field indicates this message and contains VLAN); The ID value of VLAN ID(VLAN): (self-defined); The priority of VlAN Priority(VLAN): 1(represents limit priority).
After message added VLAN, message was added the bag of encapsulation by identifying into a kind of Tagged Package() or Priority tagged Package(the wrapper that adds of priority is arranged).Guarantee that message transmits with limit priority in two or three layers of repeating process, and behind the FPGA that arrives business board preferential dissection process.
The every 3.3ms of FPGA on the main control board sends the message of 44 148 bytes at most, if business board is not on the throne, then need not to send, and promptly per second is sent out 13200 messages, and the flow maximum is about 17.74M.Use the system of point-to-point connections such as FE or GE for the backboard side, it is enough that remaining bandwidth is used for management channels.
In addition, when the FPGA of slave control board was in stand-by state, the CPU that also can receive this master control borad write and revises the content of write-only register, but the literary composition of outwards not transmitting messages, and receive only the message that each business board sends; Handle like this is to be consistent in order to guarantee that soft, the hardware state of control centre are switched in all kinds of protections on each master control borad.
Business board is on the direction of master control borad, and the send mode of message and above-mentioned master control borad are similar to the working method of business board, comprising:
Wherein, the purpose MAC(physical address of VLAN), each 6 byte of source MAC, VLAN label 4 bytes, CRC check 4 bytes increase by 20 bytes altogether, purpose MAC is the MAC Address of main control board, VLAN priority is set to represent limit priority.
Step 3, the FPGA on the business board will add the message of VLAN, sends to three/two layers of exchange chip of main control board by two layers of exchange chip;
Step 4, three/two layers of exchange chip of main control board learn it is the message of HW line between plate according to VLAN, and this message is transmitted to the port (also being the GE port) at the FPGA place of this plate, and issue the GE mouth between slave control board;
Step 5 after three/two layers of exchange chip of standby N CP receive message, is transmitted to this message the GE port at the FPGA place on the slave control board;
Step 6, after the FPGA of primary and backup master control borad receives message, according to source MAC know message from business board, the message payload is taken out, deposit in the read-only register of corresponding service plate correspondence (128 byte), for the CPU visit of this master control borad.
Simultaneously, active and standby with needing synchronizing information between the master control borad, because use is chip-stacked, so this information synchronization has become the information transmission of chip internal, efficient can be very high.Simultaneously, can realize easily that also the data of a certain port of main control board are forwarded to a certain port of slave control board fast, thereby make active and standby application more flexible with master control borad.
For partial content such as K1(APS control signaling 1), K2(APS control signaling 2), the SF(dropout) and the SD(Signal Degrade) etc.; FPGA also needs to discern it to be changed, and in time produces the CPU that interrupt signal is notified this master control borad.Need to provide the read-only register of 128 bytes on the master control borad for each business board and business interface board slot position, 16 professional board slot positions, 28 business interface board slot positions need the read-only register of 128*44=5632 byte altogether.
For guaranteeing the real-time of transmission information, the transmission cycle of message is decided to be 3.3ms, be that per second sends 300 messages, message length is 148 bytes, occupied bandwidth is 0.4M, every business board is accounted for about 0.4% of its 100M ethernet communication bus, and the 1GE port that FPGA connected on master control borad, the flows that 44 business boards send at most are about 0.4*44=17.6M.The FPGA of primary and backup master control borad provides the write-only register of 128*44=5632 byte for the CPU of this master control borad by the CPU parallel interface, is used to send HW line information to each business board.
