Description
Technical field
The invention belongs to network communication field, more particularly to a kind of hardware forwarding table error correction method, device and computer
Readable storage medium storing program for executing.
Background technology
In order to reach the surface speed forwarding and offloading the CPU of data, existing three-layer switching equipment is mainly based upon
Hardware forwarding table is forwarded to IP messages.This forwarding mechanism is main by software forward list item and hardware forwarding table Xiang Wei
Shield, wherein, software forward list item includes forwarding information list item (Forward Information Base, FIB) and address resolution
Agreement (Address Resolution Protocol, ARP) list item, hardware forwarding table includes route table items, MAC Address and turned
Send out data table items (Forward Data Base, FDB), next-hop (nexthop) list item and three layer interface list items.
The existing literary process of three-layer switching equipment processing IP datagram includes：When receiving IP datagram text, search hard
Part forwarding-table item, and content modification and forwarding IP datagram text according to hardware forwarding table.If hardware forwarding table does not have
There is correct routing iinformation, IP datagram text may be sent to CPU processing due to lacking forwarding-table item, pass through software learning to phase
The route table items answered, and hardware forwarding chip is issued to, the IP datagram text for being subsequently sent to identical mesh ground can be by hardware
Forwarded, so as to reach surface speed forwarding.If hardware forwarding table is without correct routing iinformation, another processing IP data
The mode of message is probably directly to be discarded rather than being sent to CPU processing.
Although above-mentioned existing method is when hardware forwarding table item is not present, but touched by the way that IP datagram text is sent into CPU
Software learning routing iinformation is sent out, so as to solve the problems, such as the surface speed forwarding of IP datagram text.However, when hardware forwarding table is deposited
, but some contents it is incorrect when, IP datagram text then may be simply discarded or be forwarded to mistake port.Due to message
CPU is not sent to, software can not be triggered and go to correct or relearn route table items, causes network to occur abnormal.In order to by net
Network repairs normal, otherwise restart three-layer switching equipment, or after by keeper, the related network interface of service disconnection is closed
Restart, however, either which kind of processing mode, is required for manual intervention, inevitably result in the interruption of business
Urgently industry is solved above-mentioned technical problem.

In describing below, in order to illustrate rather than in order to limit, it is proposed that such as tool of particular system structure, technology etc
Body details, thoroughly to understand the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known system, device, electricity
Road and the detailed description of method, in case unnecessary details hinders description of the invention.
In order to illustrate technical scheme, illustrated below by specific embodiment.
Accompanying drawing 1 is the implementation process schematic diagram of hardware forwarding table error correction method provided in an embodiment of the present invention, main bag
Following steps S101 to S104 is included, is described in detail as follows：
S101, generation hardware forwarding table.
In embodiments of the present invention, route learning module gets route by fib table, ARP and FDB list items and turned
Send out after relevant information, routing forwarding relevant information is issued to hardware view, generation hardware forwarding table, and from hardware forwarding table
Item obtains hardware route forwarding relevant information.
S102, caching hardware route forwarding relevant information.
S103, forwards relevant information to detect hardware forwarding table according to the hardware route of caching.
As one embodiment of the invention, relevant information is forwarded to carry out hardware forwarding table according to the hardware route of caching
Detection S1031 and S0132 can be realized as follows：
S1031, periodically traversal caching hardware route forwarding relevant information, the rope of hardware table item needed for obtaining forwarding
Draw.
In embodiments of the present invention, wherein, hardware route forwarding relevant information include forwarding needed for hardware table item index
(index), three-layer routing list item includes purpose IP address and mask etc., the MAC Address of three layer interface list items, next-hop list item
Relevant field is next-hop ip address, the MAC Address of two layers of FDB list items and port etc..
S1032, according to forwarding needed for hardware table item index, successively to three-layer routing list item, three layer interface list items, two layers
Forwarding data table items and next-hop list item are detected, and send the information of mistake to correct after detection finds mistake.
Specifically, step S1032 realization S1 to S5 can be realized as follows：
S1, reads three-layer routing list item corresponding with index.
Three-layer routing list item mainly includes the information such as purpose IP address and mask, can according to the index of three-layer routing list item,
Three-layer routing list item corresponding with the index is read from hardware forwarding table.
Whether S2, detection three-layer routing list item is correct.
In embodiments of the present invention, whether detection three-layer routing list item is correctly mainly testing goal IP address and mask etc.
Whether information is correct.
S3, if three-layer routing entry error, sends the information of three-layer routing list item detection mistake to correct.
If three-layer routing entry error, the information that three-layer routing list item detects mistake is sent to repair module, for repairing
Multiple module corrects the mistake.
S4, if three-layer routing list item is correct, continues whether just to detect three layer interface list items and two layers of forwarding data table items
Really.
If three-layer routing list item is correct, can by the correct three-layer routing list item, get three layer interface list items and
Two layers of forwarding data table items, so as to detect three layer interface list items (the mainly MAC Address of three layer interface list items) and two layers of forwarding
Whether data table items (MAC Address of mainly two layers forwarding data table items) are correct.
S5, if three layer interface list items and two layers of forwarding data table items mistake, send three layer interface list items and two layers of forwarding
The information of data table items detection mistake is for correction.
If being detected through S4, three layer interface list items and two layers of forwarding data table items mistake then send three layers to repair module and connect
The information of oral thermometer and two layers of forwarding data table items detection mistake, so that repair module corrects these mistakes.
S104, according to the result detected through step S103, is repaired to the error hardware forwarding-table item detected.
Specifically, according to the result detected through step S103, carrying out reparation to the error hardware forwarding-table item detected can
S1041 to S1044 is realized as follows：
S1041, according to the property of mistake, the result of detection is classified.
S1042, if error hardware forwarding-table item, which belongs to, can repair error hardware forwarding-table item, mistake can be repaired by directly repairing
Miss route table items.
In embodiments of the present invention, three layers of simple error hardware forwarding-table item, for example, two layers of forwarding data table items "
Flag, next-hop mac address etc., which belong to, can repair error hardware forwarding-table item, and such mistake can be repaired directly.
S1043, if error hardware forwarding-table item belongs to unrepairable error hardware forwarding-table item, deletes address resolution association
Discuss list item.
S1044, notifies route learning module to relearn route related information.
If for example, the detection through step S1041, error hardware forwarding-table item belongs to the IP address of three-layer routing list item, covered
The unrepairable error hardware forwarding-table items such as code, then delete items of address analyzing protocol table, notifies route learning module to relearn
Route related information.
