After powering on, can be whether in place by the present signal detection module of CPLD and module local bus interface; If module is not in place, do not carry out operative configuration; If in place, CPU identifies module type by II2C interface, is judged as optical module or copper cable module.Describe as an example of copper cable module example below, if optical module, its preemphasis collocation method, with identical to carry out preemphasis configuration by the connected network equipment of copper cable module, repeats no more here.
When concrete enforcement, if while being defined as copper cable module, be CR interface type by corresponding port arrangement, CPU reads link (connection) status register bit of MAC by PCIE interface.And judge whether port is connected with Peer-Port, and if not do not connected, do not operate, if detect with Peer-Port and connect, the method providing according to the embodiment of the present invention is carried out preemphasis configuration to MAC chip.
It should be noted that, in the port generalized relating in the embodiment of the present invention, refer to whole physical port, if the each form in port form related in switch is exactly unique port; Module refers to optical module or copper cable module, and it is hot-pluggable.When corresponding ports need to be used, optical module/copper cable module is inserted into corresponding ports.The device that must exist when therefore, module is port use.
As shown in Figure 3, be the implementing procedure schematic diagram of InterWorking Equipment preemphasis collocation method in the embodiment of the present invention one, comprise the following steps:
S31, after detecting that local terminal port and Peer-Port connect, local terminal and opposite end consult to set up VSU, and to configure local terminal port be virtual switch link VSL port.
When concrete enforcement, after detecting that local terminal port and Peer-Port are set up, local terminal CPU and opposite end CPU are configured to VSU relation.Taking the port x E0 of service card in Fig. 21 and the port x E0 ' of service card 2 as example, both are after setting up opening relationships, and CPU1 and CPU2 consult to set up VSU.After having set up VSU, port x E0 is configured to VSL port by CPU1, and port x E0 ' is configured to VSL port by CPU2.CPU1 carries the mark in service card 1 affiliated VSU territory, send the property surveyed message by port x E0 to the port x E0' of service card 2, CPU2 carries the mark in service card 2 affiliated VSU territories simultaneously, send the property surveyed message by XE0' to XE0, two platform independent device build become VSU system, and the hot standby relation of definite principal and subordinate.Suppose that CPU1 is confirmed as main, in the embodiment of the present invention, preferentially port XE0 is carried out to preemphasis configuration.
It should be noted that, in the embodiment of the present invention, port XE0 is carried out to preemphasis configuration, refer to the chip relevant to port x E0 is configured, normally the chip being connected with port x E0 is configured, be that MAC chip is configured concerning this example.
S32, local terminal select successively one group of pre-emphasis parameters to configure after the chip being connected with local terminal port from preemphasis allocation list, utilize each group pre-emphasis parameters of configuration, continue to send test packet to described Peer-Port respectively in default duration.
When concrete enforcement, first CPU1 utilizes first group of pre-emphasis parameters configuration MAC chip in default preemphasis allocation list, and continue to send test packet to Peer-Port XE0 ' in default duration, Peer-Port XE0 ' resolves the test packet receiving, MAC2 judges in each test packet, whether to carry error message, and calculate the error rate (in default duration, the ratio of the quantity of the error message receiving and the test packet total quantity that receives), the like, CPU1 utilizes second group in default preemphasis allocation list successively, the 3rd group ... pre-emphasis parameters configuration MAC chip, and in default duration, continue to send test packet to Peer-Port XE0 ' respectively, MAC2 calculates the error rate corresponding to each group pre-emphasis parameters successively, until each group pre-emphasis parameters in traversal preemphasis allocation list.
Preferably, when concrete enforcement, test packet can be PRBS (pseudo-random binary sequence, Pseudo-Random Binary Sequence), CPU1 builds PRBS code stream, realizes a pseudo noise code binary generator, produces (0,1) pseudo-random binary sequence between continues to send to Peer-Port XE0 ' the PRBS code stream building by local terminal port x E0 in default duration.PRBS can, for the error rate of test high-speed serial channel transmission, test by sending PRBS code conventionally.The error rate of utilizing error rate Billy that PRBS obtains to obtain with common test message is more accurate.
Opposite end CPU verifies receiving PRBS code stream, the checking of PRBS is exactly the anti-process of the generation of PRBS, concrete grammar is first the data of receiving to be deposited to a bat (parallel data), the data of depositing are carried out to PRBS coding, data after coding compare with the data that receive, if unanimously, represent that PRBS verification is correct, PBRS test is passed through, otherwise PBRS test is not passed through.
S33, effective pre-emphasis parameters of selecting according to Peer-Port configure the chip being connected with local terminal port.
When concrete enforcement, Peer-Port can be organized pre-emphasis parameters for each, judges in default duration and whether receives error message and count the error rate according to the error message receiving, take test packet as example as PBRS, as shown in table 1:
Table 1
| Pre-emphasis parameters mark | PRBS test result | Error message quantity | The error rate |
| 1 | fail | n1 | n1/n |
| ………. | fail | n+x | (n+x)/n |
| N | fail | n2 | n2/n |
| N+1 | Pass | 0 | 0 |
| N+2 | Pass | 0 | 0 |
| …………. | pass | 0 | 0 |
| N+M | Pass | 0 | 0 |
| N+M+1 | fai | k3 | k3/n |
| …………. | fail | k+x | (k+x)/n |
| K-2 | fail | k2 | k2/n |
| K-1 | fail | K1 | k1/n |
When concrete enforcement, as long as receive an error message, judge that PBRS test result, as fail (not passing through), does not comprise an error message in all messages that only receive, just judge that PBRS test result is as Pass (passing through).In the time selecting effective pre-emphasis parameters, first CPU2 gets rid of the pre-emphasis parameters combination that test result is fail, and be the pre-emphasis parameters that successfully (quantity of the error message receiving is zero) and the error rate are zero, to select arbitrary group of pre-emphasis parameters as effective pre-emphasis parameters and by the VSL link notice CPU1 setting up between XE0 and XE0 ' from test result, CPU1 utilizes effective pre-emphasis parameters to be configured MAC chip.
Preferably, when concrete enforcement, CPU2 can be that the pre-emphasis parameters of passing through, selecting middle is effective pre-emphasis parameters from continuous test result, and pre-emphasis parameters as shown in table 1 is designated " N+2 " and the effective pre-emphasis parameters informing business of next conduct card 1 thereof.
When concrete enforcement, after local terminal (being service card 1) has been configured, carry out Turnover testing, repeat above-mentioned steps service card 2 is carried out to pre-emphasis parameters configuration.Send out test packet by CPU2 to CPU1, CPU1 carries out after analytical analysis, and effective pre-emphasis parameters of selecting is noticed to CPU2, and CPU2 completes the preemphasis configuration of corresponding ports XE0'.
CPU1 and CPU2, after effective pre-emphasis parameters of selecting according to opposite end is configured local terminal port, discharges the VSU setting up, and are common switching port by local terminal port arrangement respectively.
When concrete enforcement, the signal quality variation causing due to environmental change, and copper cable module and the switch device signal quality variation that causes service time ageing equipment to be introduced, make the signal quality transmitting between copper cable module interconnect port to change and decline along with environmental parameter.
In order to address the above problem, in the embodiment of the present invention, after local terminal port is carried out to preemphasis configuration, the environmental parameter that can also recording configuration pre-emphasis parameters is, in the time that environmental parameter changes and meets pre-emphasis parameters and reshuffle condition, be the chip configuration pre-emphasis parameters being connected with local terminal port again.Taking environmental parameter as the time and temperature be example, in the embodiment of the present invention after local terminal port is carried out to preemphasis configuration, recording configuration time and configuration temperature (in the embodiment of the present invention, taking the temperature that is configured chip as configuration temperature).Local terminal CPU monitors the temperature of current time and current MAC chip in real time, current time and setup time interval greater than Preset Time interval or Current Temperatures and configuration temperature while being greater than preset temperature interval, will be again the chip configuration pre-emphasis parameters being connected with local terminal port.
In addition, in the embodiment of the present invention, in the message that the counter register Real-Time Monitoring of opposite end MAC chip receives, whether comprise error message, once find to receive error message, to send interrupt signal to local terminal CPU, local terminal CPU, after receiving interrupt signal, for the chip being connected with local terminal port reconfigures pre-emphasis parameters, re-executes above-mentioned steps S31～step S33 by again.
It should be noted that, need to take certain bandwidth resources owing to carrying out pre-emphasis parameters configuration, for fear of causing network congestion owing to carrying out pre-emphasis parameters configuration occupied bandwidth resource, in the embodiment of the present invention, can determine currently while there is network bandwidth surplus, utilize network bandwidth surplus to carry out pre-emphasis parameters configuration.Concrete, before re-starting pre-emphasis parameters configuration, add up the current bandwidth that E-Packets and take, if with carry out pre-emphasis parameters and configure shared bandwidth sum and exceed current network maximum bandwidth, do not re-start pre-emphasis parameters configuration, if it configures shared bandwidth sum and be no more than current network maximum bandwidth with carrying out pre-emphasis parameters, re-start pre-emphasis parameters configuration.Thus, realize the dynamic-configuration of pre-emphasis parameters, can dynamically adjust along with the variation of environmental parameter (as time, temperature etc.), be current allocation optimum with the pre-emphasis parameters that ensures arbitrary moment configuration.
In the embodiment of the present invention, the network equipments configuration of two interconnected platform independent is become to VSU, two interconnected port arrangement are VSL, CPU builds pseudo noise code binary system maker and carries out the test of pseudo noise code binary sequence, opposite end is configured as pseudo noise code binary system checker and carries out verification, thereby filter out optimum preemphasis configuration parameter and notify local terminal CPU, making it carry out preemphasis configuration to local terminal.And monitoring affects the critical environments parameter of signal quality in real time, realizes adaptive configuration, improve signal quality stability, strengthen the robustness of application.
