Specific embodiment
Below by specific embodiment combination attached drawing, invention is further described in detail.
Embodiment one:
Present embodiments provide a kind of method for realizing protecting tunnel, in this method application PTN network ETREE networking, institute
State ETREE networking to include at least: a root node network equipment and multiple leaf node network equipments, the root node network are set
It is standby that service connection is carried out by pseudo-wire between the leaf node network equipment；As shown in figure 3, the guard method packet of the present embodiment
It includes:
Step 301: establishing work tunnel between the root node network equipment and at least one leaf node network equipment
The pseudo-wire of road and protection path, the connection root node network equipment and the leaf node network equipment is carried on the work tunnel and institute
It states in protection path.
For example, A equipment is ROOT node, and B, C equipment is leaf as shown in figure 4, A, B, C3 platform equipment carry out ETREE networking
Child node.A equipment is connected by pseudo-wire 1 with B device, while realizing the 1+1 protection in tunnel 1,2；A equipment is set by pseudo-wire 2 and C
Standby to be connected, pseudo-wire 2 is carried on above tunnel 3.
Step 302: when message, which enters the root node network equipment, to be forwarded, the root node network equipment study
The source MAC of the message, and the type of MAC Address is set.
When message enters A equipment, if necessary to learn source MAC, then MAC is arranged while learning MAC Address
The type of address.Learn the process of source MAC in the present embodiment as source MAC in message to be added to the MAC of A equipment
In the table of location, such as the mac address table that source MAC in the message of A equipment is added to A equipment will be entered from B device by pseudo-wire 1
In, it, at this time can be in the MAC of A equipment when the target MAC (Media Access Control) address of message is B device when forwarding other messages next time
B device can be forwarded the message to by inquiring target MAC (Media Access Control) address in the table of location and then matching corresponding port information.
The type of setting MAC Address may include: in the present embodiment
When message enters the root node network equipment from root node, the type of the MAC Address of the message is set；?
In ETREE networking as shown in Figure 4, when message enters A equipment from the root node of A equipment, learning equipment message
Source MAC, while MAC type is set, such as by the type identification of MAC Address be 0；
When message enters the root node network equipment by pseudo-wire from the leaf node network equipment, the message is set
MAC Address type；Preferentially, when message enters the root node network equipment by pseudo-wire from the leaf node network equipment
When, different types is set by the MAC Address for entering the message of the root node network equipment by different pseudo-wires；Such as scheming
In ETREE networking shown in 4, when message enters A equipment by pseudo-wire 1 from B device, the source of A learning equipment message
MAC, while it is 1 that MAC type identification, which is arranged,；When message enters A equipment by pseudo-wire 2 from C equipment, A learning equipment report
The source MAC of text, while it is 2 that MAC type identification, which is arranged,.
Preferably, the mode that the type of MAC Address is arranged in the present embodiment includes: the type of mark MAC Address, such as on
Stating setting MAC type identification is 0,1,2.Certainly mark content can be limited not only and number, or other characters, such as a,
B, c etc..
Step 303: the target MAC (Media Access Control) address for inquiring the message obtains the type of the destination address, according to the purpose
The message is forwarded in corresponding pseudo-wire by the type of MAC Address.
When E-Packeting in the present embodiment, the target MAC (Media Access Control) address of query message first in mac address table, by
In the type for being provided with MAC Address in above-mentioned steps 402, the type of target MAC (Media Access Control) address can be obtained simultaneously, then
The message is forwarded in corresponding pseudo-wire according to the type of target MAC (Media Access Control) address.Such as in ETREE group as shown in Figure 4
In net, after A equipment obtains the target MAC (Media Access Control) address type of message, it can learn that message is according to the type of MAC Address
Need to be forwarded to the tunnel pseudo-wire 1(1,2 and need double hairs), pseudo-wire 2(is only sent on tunnel 3), or it is broadcast to pseudo-wire 1 simultaneously
With pseudo-wire 2.Need double hairs when forwarding the packet the tunnel pseudo-wire 1(1,2) when realize tunnel 1+1 protection.
Embodiment two:
Illustrate the method that the present embodiment realizes protecting tunnel below with reference to the specific model of ETREE networking in PTN network；
