Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Embodiment one
Method about control message forwarding at present, may be different when each producer goes to realize, currently not
Unified specification goes to define；In communication equipment practice and message repeating process, applicants have discovered that can have such one
Kind situation, when sometimes order is switched in transmission, due to the difference of link state, so that each network node generates
Change the exception of state.
As shown in Fig. 2, present embodiments providing a kind of consistent method of each node state of holding looped network, including following step
It is rapid:
S1: control sends protection to another network node and the symmetrical network node of another network node by long path
Lock command；The long path occurred in the present embodiment refers to that the path of more nodes is undergone to be referred to as long road in looped network
The path of diameter, the corresponding less node of the command history in looped network is referred to as short path.
It is all to be sent using long path plus by the way of short path to be combined order in existing mode, specifically
, as shown in Figure 1, when need to realize the lock command of A node is transmitted to each node of looped network when, mainly have setting one
Corresponding receiving node, such as B node are directly transferred to B node by short path and by long path transmission to B node two
Kind of mode realizes the information transmitting of each node in looped network.But when going to be transmitted in this manner, it is found that,
When some intermediate node link is broken, than E or F as shown in figure 1；At this point, corresponding C and D also can not just lock message, from
And state can be caused to switch exception.Although existing mode is comparatively efficient, and is easier to carry out the design treatment of system,
It is due to being possible to the problem of will appear state translation exception, so that the stability of overall network has a degree of drop
It is low.In existing mode, selection is then single network node is combined by way of long path and short path
To be implemented.In an embodiment of the present invention, design is by long path come to another network node and another network node
Symmetrical network node sends protection lock command, in order to enable the transmission of order more accurate can be sent to each network section
Point preferably sends protection lock command, such energy to adjacent network node by long path using control in the present embodiment
It is enough to pass through most of network nodes twice so that ordering, so that also can guarantee most of even if the case where there are breakpoints
Network node can normally receive switch status order.When specifically implementation in this way, such as Fig. 3 institute
Show, issues lock command when node A sends lock command, while through the network node B and F of long road radially adjoining
APS message.
S2: each network node is in locking shape according to the protection lock command control corresponding network node received on looped network
State.After node A has sent lock command, intermediate node CDE is respectively received locking message, and handles the message information,
So that this node is in the lock state；Accordingly even when CD node is also known that lock when E or F node link is broken
Determine state, at this time, since it is in the lock state, so be not in switch exception.Since E, F node are receiving locking
After order, also state can be responded in LP (locking), while will record SF (link failure) state；So as to know that E, F are saved
The link of point is broken.
S3: when network node each in looped network no longer receives protection lock command, the locking shape of corresponding network node is removed
State.Not being due to network node each on looped network is to be in the lock state for a long time, when it no longer receives corresponding network node hair
When the protection lock command sent, at this point, lock state is removed, so as to receive other message informations to change
The state of oneself.
Node each on looped network can also be detected before being purged step: each network node pair on detection looped network
The node state answered, the node state are protection lock command reception state.
The control command conversion method that the present embodiment defines is only used for LP order, because LP requires to lock entire loop to primary
Therefore link, all nodes need to guarantee that each node knows current LP state there is no switch status as far as possible.
Embodiment two
As shown in figure 4, present embodiments providing a kind of network node, the network node is located in looped network, including following
Module:
Sending module: pass through long path to another network node and the symmetrical network section of another network node for controlling
Point sends protection lock command；Preferably, the sending module specifically: pass through long path to adjacent network node for controlling
Send protection lock command；
