Below by specific embodiment to the route sending-down method of the disclosure, device, the network equipment and machine readable storage
Medium is described in detail.
Embodiment one：
A kind of route sending-down method is present embodiments provided, this method is applied to the above-mentioned network equipment, the network equipment
The multiple exchange chips being connected including at least processor and with processor, multiple exchange chips belong to a MDC equipment,
It can so make the routing table in multiple exchange chips globally consistent.For the business board of multiple exchange chips, category can be considered as
In same MDC equipment.
The flow chart of route sending-down method as shown in Figure 1, this method comprise the following steps：
Step S101, if processor has routing iinformation to need to issue, a target is chosen from multiple exchange chips
Exchange chip.
When applying in different network environments, the processor can be the processor of business board CPU or MDC equipment, with
Under illustrate respectively in two kinds of situation.
A kind of situation is：Multiple exchange chips belong to same business board, and each exchange chip is connected with business board CPU.
If business board CPU receives the request of distal end routing operations, or when study is to new distal end route, can be from multiple exchange chips
In arbitrarily selection one exchange chip, as target exchange chip；By first exchange chip of the business board or can also be
The exchange chip for acquiescence of uniting when this mode can avoid each route sending-down, all redefines mesh as target exchange chip
Exchange chip is marked, saves program.
Another situation is：The network equipment for supporting MDC configurations, multiple exchange chips belong to same MDC equipment.
When MDC is created, master control borad CPU and business board CPU can create corresponding task process in the processor of MDC equipment, often
A MDC equipment is created, the task process of correlation will be created, the task process between different MDC equipment is separate.Such as
Fruit on the port of some MDC equipment enable OSPF (Open Shortest Path First, ospf),
The Routing Protocols such as BGP (Border Gateway Protocol, Border Gateway Protocol), it is main when study is to new distal end route
Forwarding task corresponding to control plate CPU can be synchronized to route messages in forwarding task corresponding to business board CPU.CPU pairs of business board
Current route messages are sent to drive module by the forwarding task answered, and are parsed above-mentioned route messages by drive module, are obtained
The KEY (keyword) of route：DIP (purpose IP address) and the result searched:The routing iinformations such as next-hop.
After parsing obtains routing iinformation, the processor of MDC equipment needs routing iinformation being issued to each exchange chip
Routing table in store.Now, the processor of MDC equipment can arbitrarily select an exchange chip from multiple exchange chips,
As target exchange chip；Can also be using the exchange chip of first exchange chip of MDC equipment or system default as target
Exchange chip.
Step S102, routing iinformation is issued to target exchange chip.
Specifically, routing iinformation is issued to target exchange chip by above-mentioned business board CPU or the processor of MDC equipment,
So that target exchange chip calculates the list item position of routing iinformation in the routing table according to the algorithm of setting.Wherein, the calculation of setting
Method can use conventional computational methods.For example, according to the DIP prefix computation routing iinformation affiliated point in the routing table
Branch.
Step S103, the list item position of the routing iinformation that reception target exchange chip is determined in the routing table.
Step S104, list item position and routing iinformation are issued to multiple exchange chips.
After receiving the list item position of the routing iinformation of target exchange chip return in the routing table, business board CPU or MDC
List item position and routing iinformation are issued to multiple exchange chips by the processor of equipment with broadcast mode.

All exchange chips of the network equipment all support the DMA of route to issue mode.The flow of route sending-down method shown in Figure 2
Figure, this method comprise the following steps：
Step S201, if processor has routing iinformation to need to issue, a target is chosen from multiple exchange chips
Exchange chip.Identical with above-described embodiment one, under different network environments, the processor can also be business board CPU or MDC
The processor of equipment, will not be repeated here.
Step S202, routing iinformation is issued to target exchange chip.
Step S203, the list item position of the routing iinformation that reception target exchange chip is determined in the routing table.
Processor receives the list item position of the routing iinformation of target exchange chip return in the routing table, by list item position
With the DMA buffer areas of routing iinformation storage to storage chip.Or list item position and routing iinformation are deposited by target exchange chip
Store up DMA buffer areas.
Step S204, judges whether the number of the current routing iinformation for having determined that list item position reaches predetermined threshold value；Such as
Fruit is to perform step S205；If not, return to step S201.
Step S205, each routing iinformation and corresponding list item position are issued to multiple exchange chips.
If the list item position of DMA cache bank memories storage and routing iinformation reach certain amount, disposably DMA can be cached
The list item position of area's memory storage and routing iinformation are sent directly to the routing table of each exchange chip by way of data broadcasting
In.
As another implementation of the present embodiment, processor can will first need the routing iinformation that issues to store to depositing
Store up the DMA buffer areas of chip or the DMA buffer areas of target exchange chip.Routing iinformation in DMA buffer areas reaches certain amount
Afterwards, then by target exchange chip the list item position of each routing iinformation in the routing table is calculated, then by each routing iinformation
Multiple exchange chips are issued to corresponding list item position.

If above-mentioned routing iinformation is when the routing iinformation of revocation route, the road of above-mentioned multiple exchange chips is searched respectively
By the list item position of table, and delete the routing iinformation in the list item position found；
If above-mentioned routing iinformation is the routing iinformation of route to be updated, the road of above-mentioned multiple exchange chips is searched respectively
By the list item position of table, the routing iinformation in the list item position found is replaced using the routing iinformation.
Based on this, a kind of route sending-down method is present embodiments provided, this method is with the network equipment for supporting that MDC is configured
Illustrated exemplified by middle addition route.Flow chart shown in Figure 3, this method comprise the following steps：
Step S301, when study is to new distal end route, distal end route messages are parsed by drive module, obtain route
Information.
When creating MDC equipment, master control borad CPU and business board CPU can create corresponding task in the processor of MDC equipment
Process, a MDC equipment is often created, the task process of correlation will be created, the task process between different MDC equipment is mutual
It is independent.If enabling the Routing Protocol such as OSPF, BGP on the port of some MDC equipment, when arriving new distal end by port study
During route, forwarding task corresponding to master control borad CPU can be synchronized to distal end route messages corresponding to business board CPU and forward task
In.Current distal end route messages are sent to drive module by forwarding task corresponding to business board CPU, are parsed by drive module
Said distal ends route messages, the KEY being route：DIP and the result searched:The routing iinformations such as next-hop.
Step S302, an exchange chip is chosen by MDC modules, as target exchange chip.
When creating MDC equipment, MDC modules can record the port in MDC equipment and exchange core according to the information of user configuration
The corresponding relation of piece.When being route on the port of some MDC equipment according to Routing Protocol study to new distal end, MDC equipment
MDC equipment of the forwarding module according to belonging to current corresponding to processor or business board CPU, pass through MDC modules and obtain software records
It is current belonging to MDC equipment an exchange chip, as target exchange chip.
Step S303, routing iinformation is issued to target exchange chip, so that target exchange chip calculates routing iinformation and existed
List item position in routing table.
Step S304, list item position and routing iinformation are issued to multiple exchange chips with broadcast mode, so that each friendship
Changing chip, new routing iinformation is added in corresponding list item position in the routing table.
