All other embodiment, broadly falls into the scope of protection of the invention.
It should be noted that the equipment of embodiment of the present invention indication is the network equipment that electric (light) signal forwards, including friendship
Change planes, router etc..In the embodiment of the present invention, " the first equipment ", " the second equipment " are equipment, and " first " therein and "
Two " term has different equipment just to difference.
The embodiment of the present invention provides a kind of method determining loop network, as shown in figure 1, being provided in an embodiment of the present invention
Determine the method flow schematic diagram of loop network, including：
Step 101：First equipment, after receiving looped network detection instruction, sends the respectively by each port of the first equipment
One ring perception message, the first ring perceives the device identification carrying the first equipment in message.
Specifically, the first ring perception message is used for adding the second equipment after the second equipment receives the first ring perception message
Device identification and continue send.
It should be noted that for the generation preventing looped network storm, the equipment receiving looped network detection instruction will stop transmitting-receiving
Normal data message simultaneously sends protocol massages, simultaneously each port of enabled device.Normal data message in the embodiment of the present invention
It is different from protocol massages, be the general data message of transmission after looped network is set up.
Step 102：First equipment receives the first ring perception report by the first port of the first equipment in Preset Time
Literary composition, then determine first port corresponding loop network path according to the device identification that the first ring perceives each equipment in message.
Specifically, every equipment in network topology, after receiving looped network detection instruction, sends the by each port
One ring perception message, the first ring perception message carries equipment of itself mark, receives this first perception report in next node equipment
Wen Hou, the mark continuing interpolation equipment of itself and continues to send to next node, by that analogy, until returning to message
Just send the equipment that the first ring perceives message.Wherein, device identification is the unique mark of each node on ring, for unique
Represent a node device, specifically can with the MAC of each node (Media Access Control, media access control or
Physical address, hardware address) address is representing, but it is not limited to this.
Further, each port of every equipment in network topology can send the first ring in equipment initial setting up
Perception message it is also possible to send the first ring perception message it is also possible to periodically send first when network topology sends change
Ring perceives message, and here is not limited.
, the first equipment SW1 sends the first ring perception message from each port and carries setting of SW1 taking the first equipment SW1 as a example
Standby mark ID1, the such as first ring perception message content carries { ID1 }, and the second equipment SW2 receives the first ring perception report of SW1
Wen Hou, the device identification ID2 of itself is added in this message, then amended message carries { ID1, ID2 }, and from SW2
Each port continue to send to next node SW3；SW3, SW4 same SW2 of processing mode to message.Finally, ring perception report
Literary composition returns to the first port 11 of the first equipment SW1, and the content alteration wherein carrying is { ID1, ID2, ID3, ID4 }, then first set
Standby determine that loop network path is SW1SW2SW3SW4.
It should be noted that in order to limit the broadcast on network, and realize partial data isolation, split the network into multiple
VLAN (Virtual Local Area Network, VLAN) can meet different networking requirements.Now need to hold
Mouth is divided, and different ports belongs to different VLAN groups.
In the case that port divides VLAN, the first ring perception message that each port of the first equipment sends not only carries the
The device identification of one equipment, also carries the VLAN tag of each port.Now, the first ring perception message is used for connecing in the second equipment
After receiving the first ring perception message, determine that the VLAN tag of described receiving port and the first ring perceive the VLAN tag one in message
During cause, add the device identification of the second equipment and continue to send.Additionally, the first equipment passes through the first equipment in Preset Time
First port receives the first ring perception message, if the first ring perception message carries VLAN tag, according to the first ring perception report
After the device identification of each equipment in literary composition determines first port corresponding loop network path, can also be perceived according to the first ring
The VLAN tag that message carries determines the corresponding VLAN of this loop network.
It is assumed that 11 ports of the first equipment SW1 adhere to virtual net VLAN A and virtual net separately taking the first equipment SW1 as a example
VLAN B Liang Ge department.Transmission first ring from 11 ports for the first equipment SW1 perceive message carry the device identification ID1 of SW1 with
And the VLAN tag of affiliated function, such as { ID1；VLAN A}.The port 21 of the second equipment SW2 receives the first ring sense of SW1
After knowing message, judge whether port 21 has the VLAN department consistent with VLAN A.If it is not, explanation SW1 and SW2 is not virtual at one
On the net, thus a loop network can not be constituted, then SW2 directly abandons this message and does not continue to forward.If so, then setting itself
Standby mark ID2 is added in this message, and amended message carries { ID1, ID2；VLAN A }, and continue from each port of SW2
Supervention delivers to next node SW3；SW3, SW4 same SW2 of processing mode to message.Finally, ring perception message returns to first and sets
The first port 12 of standby SW1, the content alteration wherein carrying is { ID1, ID2, ID3, ID4；VLAN A }, then the first equipment determines
Going out loop network path is SW1SW2SW3SW4, and affiliated VLAN department is VLAN A.
Further, the first equipment SW1 receives the second ring perception message, and determines in the second ring perception message whether take
With the device identification ID1 of the first equipment SW1, if not carrying, perceiving in message in the second ring and sequentially increasing setting of the first equipment
Standby mark ID1, and send the second ring perception message.
For example, the second equipment SW2 sends the second ring perception message { ID2 } from each port, and the first equipment SW1 receives
After the second ring perception message of SW2, judge that this message does not carry the device identification ID1 of itself, then by the equipment mark of itself
Know ID1 to be added in this message, then amended message carries { ID2, ID1 }, and from each port of SW1 continue to send to
Next node.
Further, the first equipment SW1 receives the 3rd ring by second port 12 in Preset Time and perceives message, really
Fixed 3rd ring perceives the device identification ID1 carrying the first equipment SW1 in message and the first ring perceives setting of each equipment in message
The device identification that standby mark perceives each equipment in message with the 3rd ring is identical, then the first equipment SW1 determines first port 11 He
Second port 12 is the central port in loop network path, and loop network path is the first ring perception message or the 3rd ring perception message
The path of each equipment composition of middle journal.
For example, the second port 12 of the first equipment SW1 receive the 3rd ring perception message in carry ID1, ID4, ID3,
ID2 }, and the first port 11 of SW1 receives in the first ring perception message and carries { ID1, ID2, ID3, ID4 }, due to the 3rd ring sense
It is identical with the device identification that the first ring perception message carries to know message, then the first equipment SW1 determines a loop network path
For SW1SW2SW3SW4, the central port 11,12 of corresponding SW1；Or SW1SW4SW3SW2, the central port 12,11 of corresponding SW1, two
Person takes one.
If additionally, the 3rd port 13 of the first equipment SW1 does not receive the first ring perception message in Preset Time, will
3rd port 13 is defined as no central port, and no central port 13 is then switched to forwarding data mode.Wherein, Preset Time is permissible
For the setting multiple of protocol massages transmission time, for example, it can be 1 second～3 seconds.
Behind the loop network path determining the first equipment SW1 and its corresponding central port, can choose whether to configure
For ring, can be configured as automatically setting up ring.First equipment SW1 after receiving looped network setting instruction, by first port 11 and the
Two-port netwerk 12 sets up cyclization, and sets up message { ID1, ID2, ID3, ID4 } by the first central port 11 transmission ring, and ring sets up message
Including loop network path so that each equipment SW2, SW3 and the SW4 in loop network path according to loop network route matching
Central port set up ring.
For example, SW2 receive SW1 transmission ring set up message { ID1, ID2, ID3, ID4 }, judge this loop network path
Include equipment of itself mark ID2, and search this corresponding port in loop network path itself determining, for example, port 21 He
Port 22.SW3, SW4 set up the same SW2 of process of message to ring.
After loop network establishes, other redundancy protocols such as DRP can be associated and carry out looped network state-maintenance.Additionally,
In order to ensure the normal operation of looped network, each node on ring needs the state of the link that real-time detection itself connected.
Embodiments provide a kind of method determining loop network, the first equipment is receiving looped network detection instruction
Afterwards, the first ring is sent respectively by each port of the first equipment and perceive message, in the first ring perception message, carry the first equipment
