Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The flow chart of the message forwarding method that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for present embodiment comprises:
When other equipment in the network send message to three-tier switch, can in the message that sends, carry IP address information (source IP address and purpose IP address), carry out three layers of forwarding for three-tier switch.Three-tier switch carries out three layers and transmits base three layers of routing table of storage thereon, stores purpose IP address and next jumping identification information corresponding with purpose IP address in these three layers of routing tables.Next of present embodiment jumped identification information and mainly referred to the information of the route outgoing interface corresponding with purpose IP address and the next-hop ip address of this route outgoing interface, and the information of route outgoing interface comprises outgoing interface type and outgoing interface index.When the route outgoing interface was physical port under the VLANIF, the type of this outgoing interface was VLANIF, and the outgoing interface index is the VLAN value that VLANIF is designated this VLANIF correspondence.For example: if create the VLANIF of VLAN 100 correspondences, then the outgoing interface index of VLANIF correspondence is VLAN 100.
Three-tier switch analytic message and the purpose IP address that obtains message are three layers of routing table of input inquiry with the purpose IP address of message; If in three layers of routing table, inquire the IP address identical with purpose IP address, then obtain corresponding next the jumping identification information in the IP address identical with purpose IP address.
Wherein, for the message that receives, if local three-tier switch is its final jump, namely the purpose IP address of message is the IP address of certain physical port of three-tier switch, next that then obtain jumped in the identification information will not comprise next-hop ip address, and only comprise route outgoing interface information.If local three-tier switch is not its final jump, next that then obtain jumped identification information and comprised route outgoing interface information and next-hop ip address simultaneously.
In the present embodiment, be that physical port under the VLANIF is example with the route outgoing interface, then the outgoing interface information spinner will refer to the VLANIF sign, that is the VLAN value of VLANIF correspondence.
Wherein, next-hop mac address refers to the MAC Address of next-hop ip address corresponding physical equipment.In the present embodiment, ARP table by next jump identification information and with it the next-hop mac address of correspondence form.Namely when next jumping identification information comprises next-hop ip address, only comprise the corresponding relation of route outgoing interface information, next-hop ip address and next-hop mac address in the ARP table; When next jumps identification information when not comprising next-hop ip address, the ARP table only comprise certain physical port on route outgoing interface information, the three-tier switch IP address (being the purpose IP address of message) and with the MAC Address of the direct-connected equipment of this physical port.
Concrete, when next jumping identification information comprises route outgoing interface sign (for example VLANIF sign) and next-hop ip address, three-tier switch specifically with route outgoing interface sign (with next-hop ip address be input inquiry ARP table, and obtain the MAC Address (being next-hop mac address) in the list item that all mates with route outgoing interface sign and next-hop ip address in the ARP table.Wherein, but this next-hop mac address unique identification receives next physical equipment of this message.
When next jumps that identification information only comprises route outgoing interface sign and when not comprising next-hop ip address, three-tier switch is input inquiry ARP table with the purpose IP address in route outgoing interface sign and the message, and obtain in the ARP table identify with the route outgoing interface and message in the list item that all mates of purpose IP address in MAC Address (being next-hop mac address).At this moment, this next-hop mac address corresponding physical equipment directly links to each other with three-tier switch by route outgoing interface sign corresponding physical port, and is the final recipient of this message.
Because in the present embodiment, do not store the port information that the network equipment of next-hop mac address correspondence is connected with three-tier switch in the ARP table, therefore, three-tier switch is after inquiry ARP table gets access to next-hop mac address, further according to the next-hop mac address inquiry two-layer retransmitting table that obtains, to obtain next-hop mac address corresponding port information (being outbound port information).
Wherein, on three-tier switch, also store two-layer retransmitting table, store the MAC Address of port information and the network equipment that each physical port connects of three-tier switch in this two-layer retransmitting table, carry out two layers of forwarding for three-tier switch.Concrete, three-tier switch as the input inquiry two-layer retransmitting table, and obtains MAC Address corresponding port information identical with this next-hop mac address in the two-layer retransmitting table with the next-hop mac address obtained.
After obtaining the next-hop mac address corresponding output port, three-tier switch forwards message from this outbound port, namely is transmitted to the network equipment of next-hop mac address correspondence.
The message forwarding method of present embodiment, three-tier switch is at first according to three layers of routing table of purpose IP address search of message, obtain next and jump identification information, jump identification information inquiry ARP table according to next then and obtain next-hop mac address, search two-layer retransmitting table according to the next-hop mac address of obtaining again, obtain outbound port, by outbound port message is forwarded, make the ARP table can only comprise next jumping identification information and corresponding MAC Address, and no longer comprise and MAC Address corresponding port information, therefore, when the switching of VLAN inner port takes place, do not need to carry out ARP study, can utilize the study of two-layer retransmitting table to realize the renewal of MAC Address and port information corresponding relation, solved when the VLAN inner port taking place switch because producing the problem that a large amount of ARP Miss messages and ARP request message cause extremely busy and flow interrupt of three-tier switch moment, improved message forwarding efficient.
Based on above-described embodiment, support at VLAN under the situation of port backup, master port and backup port switch, the network equipment that is connected with master port is described, again be connected with three-tier switch by another physical port (backup port), illustrate that switching has taken place the outbound port between three-tier switch and this network equipment.Wherein, because the outbound port before and after switching belongs to same VLAN, therefore, the VLANIF sign does not change with the corresponding relation of MAC Address; Again because only comprise the corresponding relation of VLANIF sign, next-hop ip address and next-hop mac address in the ARP of the present embodiment table, and do not comprise port information, therefore, when outbound port switches, information in the ARP table can not change, do not need to trigger ARP study, just can not produce a large amount of ARP Miss message and a large amount of ARP request message yet, alleviated the burden of three-tier switch when port switches, simultaneously owing to do not carry out ARP study and just not can produce because the flow interrupt that ARP study causes has improved the efficient and the quality that E-Packet yet.
Further, for three-tier switch, when receiving message, three-tier switch can be by obtaining employed physical port when receiving message and resolving the message that receives to obtain source MAC wherein, set up the corresponding relation of the MAC Address of the network equipment that physical port is connected with physical port, to form two-layer retransmitting table.In addition, three-tier switch also can dynamically update two-layer retransmitting table according to the actual operating position of its each physical port, and its renewal process is identical with the process of above-mentioned formation two-layer retransmitting table.Therefore, when the port in VLAN takes place switches, three-tier switch can be learnt physical port according to the message that receives switching has taken place, and according to the physical port renewal two-layer retransmitting table after switching, the MAC Address corresponding port information updating that is about to former outbound port correspondence is the outbound port after switching; The corresponding relation of the MAC Address that the information of the outbound port after will bank switching in the two-layer retransmitting table after renewal is corresponding with former outbound port.Because the two-layer retransmitting table on the three-tier switch is safeguarded by special hardware module that usually therefore, its renewal speed compares comparatively fast.
Based on above-mentioned, under the situation that port switches, the MAC Address of obtaining according to inquiry ARP table when three-tier switch, remove to inquire about two-layer retransmitting table to carry out two layers when transmitting, can obtain correct outbound port, namely can get access to the outbound port after the switching, thereby guarantee that message transmits by correct outbound port, can guarantee that namely message is successfully transmitted.
In the various embodiments described above, before jumping identification information inquiry ARP table according to next, obtaining next next-hop mac address of jumping the identification information correspondence, also comprise: according to the arp response message that receives, generate the process of ARP table.Concrete, three-tier switch generates the ARP request message according to the purpose IP address of first message, and broadcasts these ARP request messages according to VLAN value all physical ports under corresponding VLAN IF that message carries when receiving first message; After other network equipments that belong to same VLAN that are connected with three-tier switch in the network received the ARP request message, whether the IP address of judgement itself was identical with the IP address used of request MAC Address in the ARP request message; If inequality, then do not do response; If identical, then send the arp response message to three-tier switch, carry IP address and the MAC Address of this network equipment in this arp response message.After three-tier switch receives the arp response message, store to form ARP and show receiving the IP address of the network equipment in the information (being the VLAN value of VLANIF correspondence and VLANIF type etc.) of the route outgoing interface of arp response message and the arp response message and MAC Address.Wherein, identification information is jumped as next in the IP address of the information of route outgoing interface and the network equipment, and the MAC Address of the network equipment is as next-hop mac address.
As seen from the above analysis, in the present embodiment, three-tier switch is in the ARP learning process, only with the information learning of outbound port to the VLANIF aspect, rather than study is to concrete physical port, realized separating of ARP table and physical port, make and taking place not need to carry out ARP study when the VLAN inner port is switched, and obtain next-hop mac address by inquiry ARP, and search two-layer retransmitting table according to the next-hop mac address of obtaining then to find outbound port, finish message forwarding.
The message forwarding method of present embodiment, at first search three layers of routing table and obtain next jumping identification information, obtaining next-hop mac address according to next jumping identification information inquiry ARP table, search two-layer retransmitting table according to next-hop mac address then, make message be forwarded to two layers of forwarding module by three layers of forwarding module, and then the outbound port that is obtained by two layers of forwarding modules basis forwards message, three layers of forwarding and two layers of forwarding are combined, when successfully E-Packeting, make the ARP table be separated with physical port information, taking place not need to carry out ARP study when the VLAN inner port is switched, solved in the prior art because the VLAN inner port takes place and switched the problem of extremely busy and flow interrupt of the three-tier switch moment that produces that a large amount of ARP Miss message and a large amount of ARP request message cause, improved success ratio of message forwarding.
