The angle of Section Point interaction is described in detail to controlling network method for sending information of the present invention.Specifically, the present embodiment bag
Include：
101st, first node generates controlling network information.
In the embodiment of the present invention, first node and Section Point are two nodes in ISIS with neighborhood, i.e., the
One node and Section Point neighbor node each other.Train Ethernet using ISIS as control protocol when, first node, Section Point
Ether train backbone network node specially in train Ethernet（Ethernet Train Backbone Network Node,
ETBN）.In this step, first node, i.e. an ETBN are generated and carry subtype length value（Type Length Value, TLV）
Controlling network information, wherein, sub- TLV indicates the neighbours direction of first node and Section Point, and neighbours direction represents first segment
The relative direction with Section Point is put, for example, first node is located at the left direction of Section Point；For another example, first node is located at the
Two nodes have direction etc..
102nd, the first node sends the controlling network information to Section Point.
After the controlling network information for carrying sub- TLV is generated, first node to adjacent node, i.e. Section Point send control
The network information.
103rd, Section Point processes the controlling network information.
In this step, Section Point is received after controlling network information, the neighbours direction in the match control network information with
The corresponding direction in direction port, feels to store or do not store controlling network information according to matching result.
Controlling network method for sending information provided in an embodiment of the present invention, first node generates the control net for carrying sub- TLV
Network information, and it is sent to the neighbor node of itself, i.e. Section Point.During being somebody's turn to do, first node is by the way that neighbours direction is carried
The Section Point that there is neighborhood with it is sent in controlling network information, realize train Ethernet using ISIS as control
During agreement processed, first node provides the purpose of accurate controlling network information to the Section Point being adjacent.
The scene graph that Fig. 2 is suitable for by controlling network method for sending information of the present invention.Fig. 2 is refer to, the present invention is real
In applying example, there is ETBN1, ETBN2 and ETBN3, ETBN1～ETBN3 is equivalent to the IS in ISIS.For ETBN2, it has
Neighbor node ETBN1 and ETBN2.Connect multiple terminals on each ETBN（End Device, ED）, those terminals are on train
Equipment, such as controls equipment, the equipment of control air-conditioning, the equipment of control car light of car door.ETBN will obtain neighbor node control
The network information is simultaneously supplied to the terminal being connected with itself.Wherein, the first node has respectively first with the Section Point
Direction port and second direction port, the corresponding first direction in the first direction port is corresponding with the second direction port
Second direction is rightabout.
Specifically, with the ETBN2 in Fig. 2 as first node, ETBN1 and ETBN3 as Section Point as a example by, then ETBN2,
ETBN1 and ETBN3 has respectively first direction port 1,2,3,4, below first direction port 1,2,3,4 is referred to as into left-hand end
Mouthful, left-hand port correspondence left direction；ETBN2, ETBN1 and ETBN3 have respectively second direction port 5,6,7,8, below by the
Two directions port 5,6,7,8 are referred to as dextrad port, dextrad port correspondence right direction.ETBN2 reaches the left side by left-hand port 1
Node ETBN1, by dextrad port 8 right node ETBN3 is reached.
After Section Point receives the controlling network information of first node transmission, the neighbours that controlling network information is carried
Relative to the direction of first node, i.e. first node sends the corresponding direction in port of controlling network information for direction and Section Point
Matched, decided whether to store controlling network information according to matching result.
In matching process, when the Section Point receives the first segment by the second direction port of the Section Point
During the controlling network information that point is sent by the first direction port of the first node, Section Point judges the neighbours
Whether direction is consistent with the second direction, if unanimously, by the controlling network information Store in neighbor information table；It is no
Then, the controlling network information is not stored.For example, with the ETBN2 in Fig. 2 as first node, ETBN1 as Section Point as a example by,
When ETBN2 is to ETBN1 transmission controlling network information, specifically ETBN2 passes through the in esse physical links of ETBN2 and ETBN1
Send out, i.e. ETBN2 is by first direction port (having physical link) between direction port 1 and the second direction port 8 of ETBN1
Controlling network information is sent to ETBN1, then ETBN1 receives controlling network information by second direction port 8, and ETBN2
The corresponding direction in first direction port is left direction.Now, for ETBN1, ETBN1 is not aware that ETBN2 is located at its
First direction or second direction, if the neighbours direction in the controlling network information received from second direction port is designated as a left side
Direction（Send from the first direction port of ETBN2）, then ETBN1 controlling network information is stored in neighbor information table, and then
In being stored in LSDB, if the neighbours direction in the controlling network information received from second direction port is designated as right direction（From
The second direction port of ETBN2 sends）, then ETBN1 do not preserve the controlling network information.
In matching process, when the Section Point receives the first segment by the first direction port of the Section Point
During the controlling network information that point is sent by the second direction port of the first node, Section Point judges the neighbours
Whether direction is consistent with the first direction, if unanimously, by the controlling network information Store in neighbor information table；It is no
Then, the controlling network information is not stored.For example, with the ETBN2 in Fig. 2 as first node, ETBN3 as Section Point as a example by,
When ETBN2 is to ETBN3 transmission controlling network information, specifically ETBN2 passes through the in esse physical links of ETBN2 and ETBN3
Send out, i.e. ETBN2 is by second direction port (having physical link) between direction port 8 and the first direction port 1 of ETBN3
Controlling network information is sent to ETBN3, then ETBN3 receives controlling network information by first direction port 1.And ETBN2
The corresponding direction in second direction port is right direction.Now, for ETBN3, ETBN3 is not aware that ETBN2 is located at its
First direction or second direction, if the neighbours direction in the controlling network information received from first direction port is designated as the right side
Direction（Send from the second direction port of ETBN2）, then ETBN3 controlling network information is stored in neighbor information table, and then
In being stored in LSDB, if the neighbours direction in the controlling network information received from first direction port is designated as left direction（From
The first direction port of ETBN2 sends）, then ETBN3 do not preserve the controlling network information.
