The ultra-high speed and large bandwidth requirements present a great challenge to the existing bearer network, which will result in a dramatic increase in transmission bandwidth and a subsidence of all-optical nodes to the intermediate transit (midlehaul). Secondly, the harsh requirements of millisecond-level time delay and hundred nanosecond-level clock precision bring double challenges to a network architecture and nodes, and the flat network architecture and microsecond-level ultra-low time delay node equipment become the current technical development direction.

if the type of the equipment is identified to be the new upgrading equipment by the high-speed cross board card, automatically configuring the clock rate required by the new upgrading equipment, and at the moment, firstly configuring the backplane servers or link data of the cross unit into the backplane high-speed data rate corresponding to the high-speed service board card of the new upgrading equipment;
step S203: referring to fig. 4, the service unit performs different operations according to the result of the determination. The method comprises the following specific steps:
if the low-rate service board card identifies that the equipment type is old equipment, automatically configuring a clock required by the old equipment and a backplane servers or link data rate corresponding to the old equipment service board card;
if the high-rate service board card identifies that the equipment type is old equipment, subsequent processing is not carried out, and alarms such as mismatching and the like are directly reported;

step S205: and identifying the high-speed cross board card of the new upgraded equipment type to apply for acquiring the speed type information of all the board cards on the equipment from the control unit.
Step S3: the high-speed cross board card identifies that the equipment type is new upgraded equipment, the cross unit sets the corresponding speed of the serdes or link of each slot position service board card at the back plate side in the disk to be the same according to the received service disk type and speed information of each slot position from the control unit, and the step S4 is carried out.
Specifically, referring to fig. 3, step S3 includes the following steps:
step S301: the high-speed cross board card on the new upgrading equipment receives the service disk type and the rate information of each slot position from the control unit and judges the service disk type and the rate information;
step S302: if the disk type and the disk speed of a service single disk of a plurality of slot positions received by a high-speed cross board card on the newly-upgraded equipment are high-speed board cards, correspondingly setting the speed of servers or links corresponding to the slot positions of the high-speed service board card from the backplane of the cross board card to the high-speed service board cards to be high speed;
step S303: if the disk type and the disk speed of the service single disk of a plurality of slots received by the high-speed cross board card on the newly-upgraded equipment are low-speed board cards, correspondingly setting the speed of servers or links corresponding to the slots of the high-speed service board card from the backplane of the cross board card to the low-speed service board cards to be low. Steps S302 and S303 are in parallel.
Step S4: referring to fig. 3, after the cross unit sets the servers or link rate of the back plane side according to the rate type of the service single disc, the cross unit requests the single disc to configure and activate the single disc service function.
Referring to fig. 4, after the service board finishes the clock and data rate setting operation of the cost board, the service board performs subsequent initialization operation and requests other device configuration operation. The equipment can work stably. If there is a deletion or addition of a service unit or a cross unit subsequently, the process proceeds to step S5.
Step S5: after the device is powered on to complete the rate matching of the new and old devices and stably operates, the board cards of the cross units or the service units are deleted and added for various reasons. Under the condition, the crossing unit adjusts the SERDES and LINK rates of the corresponding slot positions on the back plate side of the disk according to the actual situation according to the change of the slot position information, the board card type and the service board card rate type sent by the single disk received from the control unit. The device continues to operate steadily.
Specifically, step S5 includes the following flow:
step S501: when the new upgrade device works, if the single board of the service unit is powered off or replaced, the high-rate cross unit can confirm that the single board of the service unit is powered off or replaced and the like in the slot position by monitoring a corresponding service slot position signal linkdowm at the side of the back board of the disk or receiving a corresponding slot position information change sent by the control unit and the like, and then the cross unit returns the rate of the SERDES of the slot position corresponding to the side of the back board of the disk to the default high rate.
Step S502: when the service boards of the slot positions of the service units are powered off and powered on again, or other service boards are replaced, or service boards are newly added, the service boards can apply requests of all board speed types and the like to the control unit after being powered on, or a user can carry out related configuration on the newly added or replaced service units under the control unit again.
Step S503: after receiving the service board card equipment configuration from the user or receiving the requests of the service board card for applying all board card rate types and the like, the control unit makes the configuration of issuing slot position information, board card types and service board card rate types to all the cross units of the equipment.
Step S504: the crossing unit receives the slot position information sent by the control unit, the configuration of the board card type and the service board card rate type, and modifies and sets the servers or link rate corresponding to the backplane of the crossing unit according to the data type change of each slot position service single disc. The equipment runs stably. Specifically, if a new service single disk is added, or a new service single disk is powered off and powered on again, or another service single disk is replaced, and the service or link corresponding to the slots on the backplane side of the cross unit is a high-speed single disk, the default high-speed rate is kept unchanged. If the service single disk is newly added or powered off and the service single disk is powered on again, or the replaced service single disk is a low-rate single disk, serdes or links corresponding to the slots on the back plate side of the cross unit are changed into low-rate data.
Step S505: when the new upgrade device works, if the cross board cards with slots of the cross unit are powered off and powered on again, or the cross board cards are replaced, or under the condition that the cross board cards are newly added, the cross board cards apply for requests of all board card speed types and the like to the control unit after being powered on, or a user can carry out related configuration on the newly added or replaced cross board cards through the control unit again.
Step S506: and the control unit receives equipment configuration under the user or requests of applying all board card rate types and the like from the cross board card and then issues slot position information, the board card type and the service board card rate type to all cross units of the equipment.
Step S507: the crossing unit receives the slot position information sent by the control unit, the configuration of the board card type and the service board card rate type, and powers off the crossing board cards of some slots again, or replaces the crossing board cards, or newly adds the crossing board cards, and the crossing board cards execute relevant operations of S2, S3, S4, S5 and the like again. And the service stably runs.
It can be understood that, in step S5, if there is a change of the cross unit board card or the service unit board card, such as powering off the single disk, powering on again, replacing the single board, adding a new single board, and so on, when the whole device operates stably, how to ensure the signal rate adaptation of the backplane of the whole device. That is, after steps S1 to S4 are completed, the step S5 is triggered in real time when the present network has a complaint condition. S5 does not trigger in real time when the device is stable.
