Description
Technical field
The present invention relates to the detection technique of LA Management Room operating state, relate in particular to a kind of method and device thereof that detects the gateway operating state.
Background technology
The Internet network generally is divided into several IP subnets, switch then is the network equipment that is connected a plurality of IP subnets with router, router can carry out " address translation " and routing with the packet between the different IP subnets, again packet is exchanged by switch then, carry out the compatibility transmission so that can " read " to understand the other side's packet information between a plurality of IP subnets mutually, thereby realize the packet in the whole network system is carried out without hindrance transmission.
Switch in the network system and router are when transmitting packet; the capital uses routing table to carry out routing; and in order to reduce to store the shared memory headroom of routing table; in switch and router, usually default route can be set, specify a default gateway to carry out the forwarding of packet by default route again.
Simultaneously, for the default gateway that prevents to be provided with when breaking down, router can also in time be transmitted packet, just need carry out redundant configuration to default gateway, promptly specify the different gateway of another one priority as the backup default gateway, in order to when default gateway breaks down, can in time switch to the forwarding that the backup default gateway is proceeded packet.
For switch and router, if default gateway place network may will cause default gateway unavailable because a variety of causes causes it to be shut down or other fault occurs; In this case, if switch and router can't in time be learnt the situation that default gateway breaks down, just can not in time switch to the backup default gateway, but continue to send packet, will cause losing of packet like this to the default gateway that breaks down.
For switch in the network system or router, different physical ports may be responsible for transmitting the packet in the different virtual LAN (VLAN, Virtual Local Area Network) on its equipment; If default gateway and backup default gateway belong to same VLAN, on switch or router, will take physical port more than one, be that default gateway is connected with a physical port of switch or router, the backup default gateway then is connected with the another one physical port of same switch or router, if the default gateway that is connected with switch or router is shut down or other faults occur, when causing this default gateway unavailable, switch or router will possibly can't in time be known the situation that default gateway breaks down, also, cause data-bag lost continuing to send packet to default gateway.
One is exemplified below:
If an Ethernet switch A in the network system has 24 physical ports, first physical port and second physical port are responsible for transmitting the packet in the virtual LAN VLAN 10, and the 3rd physical port to the 24 physical ports are responsible for transmitting the packet in the virtual LAN VLAN 20; All physical ports of wherein be responsible for transmitting packets in the VLAN 20 are used for connecting main frame (i.e. the 3rd physical port to the 24 physical ports be used for respectively connecting main frame) respectively; First physical port is used for connecting default gateway 10.1.1.1 (default gateway is the network equipment with routing function, and the IP address of this network equipment is exactly 10.1.1.1); Second physical port is used for connecting another Ethernet switch B (10.1.1.3), and then this Ethernet switch B just is the equal of the backup default gateway of above-mentioned default gateway 10.1.1.1.
Like this, just need on Ethernet switch A, carry out following configuration:
Ip route 0.0.0.0 0.0.0.0 10.1.1.1---the specify default gateway is 10.1.1.1
Vlan 10---create virtual LAN VLAN 10
Port e0/1 e0/2---assigned vlan 10 comprises first physical port and second physical port
Vlan 20---create virtual LAN VLAN 20
Port e0/3 to e0/24---assigned vlan 20 comprises the 3rd physical port to the 24 things
The reason port
Interface vlan 10---for VLAN 10 creates the network layer routing interface
Ip address 10.1.1.2 255.255.255.0---be the routing interface assigned ip of VLAN 10
Address 10.1.1.2 and subnet mask 255.255.255.0
Interface vlan 20---for VLAN 20 creates the network layer routing interface
Ip address 20.1.1.1 255.255.255.0---be the routing interface assigned ip of VLAN 20
Address 20.1.1.1 and subnet mask 255.255.255.0
Ethernet switch A is carrying out under the above-mentioned configuring condition, if the state that crashes has appearred in default gateway 10.1.1.1, Ethernet switch A but and do not know situation about crashing, just know at address resolution protocol (ARP, Address Resolution Protocol) list item at this default gateway in has not had that (wherein the ARP of dynamic learning can delete automatically along with the Down of physical port e0/1, wherein the Down state of physical port is meant that physical port breaks down), broken hair ARP message is not given all physical ports in the VLAN 10, remove to inquire about the Media Access Control address (MAC of default gateway, Media AccessControl), because also having 1 physical port e0/2 in the VLAN 10 is up state (wherein the Up state of physical port is meant that physical port is working properly), Ethernet switch A thinks and can arrive default gateway 10.1.1.1 by this physical port, but default gateway crashes, and e0/1 has been the down state, Ethernet switch A can not get replying certainly, so all packets that need issue default gateway 10.1.1.1 will be dropped at Ethernet switch A place, therefore may will cause the interruption of the network operation.After can only waiting until that the network management personnel searches and find the fault of default gateway appearance, in time repair the fault of default gateway, network recovery is normally moved, this time period may be a few minutes, also may be several hours break period, specifically will see the timely discovery degree of network management personnel fault.
To sum up, as can be seen, in the prior art based on the mode of the detection default gateway operating state of " physical port+VLAN sign+ARP " mode after default gateway breaks down, router or switch can not in time be found the fault that default gateway occurs, can not in time switch to the backup default gateway, thereby may cause at this section and fail in time to find that default gateway breaks down and switches in the time of backup default gateway, lose the packet that some need be transmitted, so that reduce the transmission performance of network system.

Embodiment
Method and system thereof that the present invention detects the default gateway operating state adopt in the network equipment physical port that directly is connected with default gateway to be carried out state-detection; If when detecting physical port and being in normal operating conditions (being masked as Up during the physical port operate as normal), then think with the direct-connected default gateway operating state of this physical port be normal; And if when detecting physical port and being in malfunction (being masked as when physical port is in malfunction Down), then think with the direct-connected default gateway operating state of this physical port be unusual.
As shown in Figure 1, this figure detects in the method and device thereof of default gateway operating state the simple structure block diagram that equipment room connects in the present invention.The hypothesis network equipment is an Ethernet switch 1 among the figure, certainly the network equipment can also be other equipment such as router, (default gateway is the network equipment with routing function to suppose physical port port1 on the Ethernet switch 1 directly to connect a default gateway 2, this network equipment has an IP), and the physical port port2 on this Ethernet switch 1 directly connects the another one default gateway, with as backup default gateway 3, Ethernet switch 1 just can be by detecting the operating state of self physical port port1 like this, judges the operating state situation with the direct-connected default gateway 2 of port1.And when port1 was in the Up state, promptly operating state just often then can be reached a conclusion: the operating state of default gateway 2 is normal, and at this moment Ethernet switch 1 packet that needs to mail to other subnets at first sends to default gateway 2; And when port1 is in the Down state, when being malfunction, then can reach a conclusion: the operating state of default gateway 2 is unusual, at this moment Ethernet switch 1 just can not at first send to default gateway 2 with the packet that needs mail to other subnets, because it breaks down, but the packet that those will be mail to other subnets sends to the backup default gateway 3 that plays redundant effect that does not break down.
With reference to Fig. 2, this figure is the concrete process flowchart of the present invention's method of detecting the default gateway operating state; Concrete processing procedure by network equipment detection default gateway operating state among the figure is as follows:
Step S10, by the network equipment physical port that self directly is connected with default gateway being carried out recurrent state detects, here for to make the probability of data-bag lost drop to minimum, preferably adopt with periodic law and detect the direct-connected physical port that default gateway is arranged, can in time find the direct-connected malfunction that the physical port of default gateway is arranged like this, handle so that in time take measures to carry out fault restoration and packet is transmitted to the backup default gateway.
Step S20, the network equipment judge that the operating state of detected physical port still is malfunction Down for normal operating conditions Up; If be normal operating conditions Up then execution in step S40; Otherwise execution in step S30.
Step S30 when the network equipment finds that the direct-connected physical port that default gateway arranged is the Down state, thinks that then the operating state of default gateway is unusual, goes to execution in step S50.
Step S40 when the network equipment finds that the direct-connected physical port that default gateway arranged is the Up state, thinks that then the operating state of default gateway is normal, goes to execution in step S90.
Step S50, generate a notice message by the network equipment and issue network management workstation, include the information that default gateway breaks down in this notice message, go wrong with webmaster personnel default gateway by this notice message notifying network management workstation, need in time repair, thus the reaction time of realizing accelerating network failure; The webmaster personnel in time carry out trouble shoot to the default gateway that breaks down and handle and corresponding repair process after receiving this notice message;
The wherein above-mentioned notice message that is generated by the network equipment can be trap (Trap) message, also can be debugging (Debug) message, also can be daily record of work message (Syslog) message, here with the network equipment when default gateway breaks down, generating trap (Trap) message is that example is elaborated.When the network equipment detects default gateway and fault occurred, generate a trap (Trap) message to network management workstation (NMS by network equipment generation or by the Agent that acts on behalf of that is provided with in the network equipment, NetworkManagement Station), wherein include the information that default gateway breaks down in this trap message, go wrong with webmaster personnel default gateway, need in time repair by this trap message notice network management workstation; The webmaster personnel in time carry out trouble shoot to the default gateway that breaks down and handle and corresponding repair process when receiving this Trap message;
Meanwhile, the network equipment is when default gateway breaks down, for mailing to the default gateway that breaks down, the packet that prevents to mail to other subnets can cause losing of packet, but packet is transmitted to the backup default gateway, with the packet route and be transmitted to the purpose subnet, at this moment the network equipment will carry out default gateway to the packet of backup default gateway and transmits handover operation by the backup default gateway.
Step S60, after the network equipment found that the default gateway operating state is unusual, this network equipment also will continue the physical port that directly is connected with default gateway is detected; Recover normal with the operating state that can in time find default gateway.
Step S70, the network equipment judge that once more the operating state of detected physical port still is malfunction Down for normal operating conditions Up; If detect with the direct-connected physical port of default gateway and revert to normal operating conditions Up, then go to execution in step S80 by malfunction Down; If the physical port direct-connected with default gateway still is in malfunction Down, then transfers back to step S60 and continue have the physical port of default gateway to detect direct-connected.
When step S80, the network equipment detect and revert to normal operating conditions Up with the direct-connected physical port of default gateway by malfunction Down, just think that default gateway has been a normal operating conditions by the abnormal work recovering state;
The packet hairnet default gateway that step S90, the network equipment directly will mail to other subnets is transmitted processing, and then goes to step S10, and continuing has the physical port of default gateway to detect to direct-connected.
By above-mentioned flow processing, just can make the network equipment can in time find the situation that default gateway breaks down, taking packet that disaster recovery measure timely maybe will mail to default gateway to be transmitted to other backup default gateways handles, and after the default gateway operating state is recovered normal operation again, packet being sent to default gateway handles again, thereby realized timely detection to the default gateway operating state, reduce the packet loss of packet in transmitting processing procedure, improved the transmission performance of network system.
One illustrates as follows:
If an Ethernet switch A in the network system has 24 physical ports, wherein first physical port and second physical port are responsible for transmitting the packet in the virtual LAN VLAN 10; First physical port is used for connecting default gateway 10.1.1.1 (default gateway is the network equipment with routing function, and the IP address of this network equipment is exactly 10.1.1.1); Second physical port is used for connecting another Ethernet switch B (10.1.1.3), and then this Ethernet switch B just is the equal of the backup default gateway of above-mentioned default gateway 10.1.1.1.
Like this, detect the method for default gateway operating state based on the present invention, just need (Ethernet switch A be exactly one of above-mentioned described network equipment at Ethernet switch A, wherein the network equipment can also comprise other equipment such as router) on carry out the configuration of track e0/1 action, just can lost data packets, concrete configuration is as follows:
ip?route?0.0.0.0?0.0.0.0?10.1.1.1?preference?15?track?e0/1
---specify a default gateway 10.1.1.1, its priority is 15, and (if the state of physical port e0/1 is up, this instructs allocation activation specify to detect the up/down state of physical port e0/1; If the state of physical port e0/1 is Down, then this instruction loss of configuration)
ip?route?0.0.0.0?0.0.0.0?10.1.1.3?preference?30?track?e0/2
---specify a backup default gateway 10.1.1.3, its priority is 30, and (if the state of physical port e0/2 is up, this instructs allocation activation specify to detect the up/down state of physical port e0/2; If the state of physical port e0/2 is Down, this instructs loss of configuration)
After configuration is finished like this, the priority that connects default gateway 10.1.1.1 in Ethernet switch A is 15, be higher than the priority 30 that connects Ethernet switch B (being the backup default gateway), if two instruction is in state of activation simultaneously, article one, works, Ethernet switch A will think that default gateway 10.1.1.1 can use, and constantly sends packet to default gateway 10.1.1.1.
If but physical port e0/1 is when normal operating conditions Up becomes malfunction Down, parametric t rack will work, the state of activation of article one instruction will be cancelled automatically, at this moment second instruction beginning is worked automatically, and (routing table oneself has a cover to transmit handover mechanism, its management of switching repeating process comes to this), backup default gateway 10.1.1.3 (Ethernet switch B) becomes new default gateway, Ethernet switch A will think that backup default gateway 10.1.1.3 can use, constantly send packet to backup default gateway 10.1.1.3, the packet in the network system just can not lost like this.
If Ethernet switch A detects the physical port e0/1 of self when reverting to normal operating conditions up again by malfunction Down, parametric t rack will work again, restart this priority and be 15 instruction route, Ethernet switch A just sends packet to default gateway 10.1.1.1 again like this.
By above-mentioned illustration, as seen the setting of instructing by priority, after can be implemented in the direct-connected physical port that default gateway arranged and breaking down, automatically switch to the backup default gateway and carry out packet forwarding processing, and the operating state of the direct-connected physical port that default gateway arranged recover normal after, can also automatically switch to the forwarding that default gateway carries out packet from the backup default gateway and handle.
Prove through experimental result repeatedly, add parametric t rack in above-mentioned routing statement after, the failure detection time of default gateway can be controlled in 1 second, if default gateway breaks down, (1 second) just can switch to the backup default gateway at once, has improved the reliability of Network Transmission greatly.If in network system, do not have under the situation of configuration backup default gateway, the network equipment also can be based on Simple Network Management Protocol (SNMP, Simple Network Management Protocol) use is acted on behalf of an Agent generation trap (trap) message and is issued network management workstation NMS, to remind the webmaster personnel that default gateway breaks down, require to carry out immediately trouble shoot and repair operation, thus the fault reaction time of accelerating network.
Accordingly, the invention allows for a kind of device that detects the default gateway operating state, this device can be placed on network device internal, also can place separately, come the physical port that directly is connected with default gateway on the network equipment is carried out the detection of operating state, thereby realize the operating state with the direct-connected default gateway of this physical port is detected.
With reference to Fig. 3, this figure is the simple structure composition frame chart of the present invention's device of detecting the default gateway operating state; The concrete component units of device that detects the default gateway operating state among the figure mainly comprises port status detecting unit 10 and generation unit 20 as a result, and the relation and the function of these two unit are specific as follows;
