After S502, Node B receive the first signaling message that node A sends, the sign of Node B is added in the first signaling message, forms the second signaling message, then the second signaling message is sent to adjacent node C.Because Node B is not done any processing to the wavelength information of carrying in the first signaling message, only the second signaling message is pass-through to adjacent node C, (λ 1 (1), and λ 2 (1) so this second signaling message carries AB, λ 3 (1), and λ 4 (1)).
S503, with in like manner above-mentioned, after node C receives the second signaling message that Node B sends, the sign of node C is added in the second signaling message, form the 3rd signaling message, then the 3rd signaling message is sent to adjacent node D.Because node C does not do any processing to the wavelength information of carrying in the second signaling message, only the 3rd signaling message is pass-through to adjacent node D, (λ 1 (1), and λ 2 (1) so the 3rd signaling message carries ABC, λ 3 (1), and λ 4 (1)).

After S505, node A receive this response message, (λ 3 (0) according to the ABCD that carries in this response message, λ 4 (0)) and the signaling message that self sends, (λ 3 to obtain wavelength connection relationship information ABCD based on λ 3 and λ 4, λ 4), then directly send the confirmation message of carrying ABCD (λ 3, and λ 4) to node D, perhaps the direction along A-＞B-＞C-＞D sends to Node B, node C and node D successively.
Node D can obtain wavelength connection relationship information ABCD based on λ 3 and λ 4 according to this acknowledge message, and (λ 3, λ 4), the λ 3 that also can be according to λ 3 and λ 4 carries in the information of ripple under node D and the 3rd signaling message and the information of λ 4 are obtained the wavelength connection relationship information based on λ 3 and λ 4.In like manner, intermediate node B and C can obtain wavelength connection relationship information ABCD based on λ 3 and λ 4 according to the confirmation message that receives, and (λ 3, λ 4), perhaps the basis response message that receives and the signaling message that self sends obtains the wavelength connection relationship information based on λ 3 and λ 4.Need to prove, the wavelength that " ABCD (λ 3, and λ 4) " expression is connected with λ based on λ 3 connects A-B-C-D, and indication λ 3 and λ 4 ripple on node A, under node D ripple.
Above-described embodiment is based on λ 3 and λ 4, specifically described the technical scheme how node A, B, C and D obtain wavelength connection relationship information; Following another embodiment accepts step S504 and continues the technical scheme how description node A, B, C, D, E and F obtain wavelength connection relationship information based on λ 1 and λ 2.
S506, because λ 1 and λ 2 do not descend ripple at node D, after node D receives the 3rd signaling message of node C transmission, be added in the 3rd signaling message the sign of node D and the information of deletion λ 3 and λ 4, ABCD is carried in formation, and (λ 1 (1), λ 2 (1)) the 4th signaling message, then the 4th signaling message is sent to adjacent node E.
S507, with in like manner above-mentioned, after node E receives the 4th signaling message that node D sends, the sign of node E is added in the 4th signaling message, form the 5th signaling message, then the 5th signaling message is sent to adjacent node F.Because node E does not do any processing to the wavelength information of carrying in the 4th signaling message, only the 5th signaling message is pass-through to adjacent node F, so the 5th signaling message carries ABCDE (λ 1 (1), and λ 2 (1)).
After S508, node F receive the 5th signaling message of node E transmission, the λ 1 that carries in the information of node F ripple under node F according to λ 1 and λ 2 and the 5th signaling message and the information of λ 2, determine with node A between based on the wavelength connection relationship that has λ 1 and λ 2, and the response message of the wavelength information of the identification information of node of signaling message process and lower ripple is carried in transmission.Particularly, this response message carries ABCDEF, and (λ 1 (0), λ 2 (0)), wherein " (λ 1 (0); λ 2 (0)) " expression node F processes the wavelength information of carrying in the 5th signaling message, " 0 " expression λ 1 and λ 2 ripple under node F in bracket.Node F can directly issue node A with this response message; Perhaps, node F also can send to along the direction of F-＞E-＞D-＞C-＞B-＞A node E, node D, node C, Node B and node A successively.
After S509, node A receive this response message, (λ 1 (0) according to the ABCDEF that carries in this response message, λ 2 (0)) and the signaling message that self sends obtain, (λ 1 to obtain wavelength connection relationship information ABCDEF based on λ 1 and λ 2, λ 2), then (λ 1 directly to carry ABCDEF to node F transmission, λ 2) confirmation message, perhaps the direction along A-＞B-＞C-＞D-＞E-＞F sends to Node B, node C, node D, node E and node F successively.
Node F can obtain wavelength connection relationship information ABCD EF based on λ 1 and λ 2 according to this acknowledge message, and (λ 1, λ 2), the λ 1 that also can be according to λ 1 and λ 2 carries in the information of ripple under node F and the 5th signaling message and the information of λ 2 are obtained the wavelength connection relationship information based on λ 1 and λ 2.In like manner, intermediate node B, C, D and E also can obtain wavelength connection relationship information ABCDEF based on λ 1 and λ 2 according to the confirmation message that receives, and (λ 1, λ 2), perhaps the basis response message that receives and the signaling message that self sends obtains the wavelength connection relationship information based on λ 1 and λ 2.Need to prove, the wavelength that " ABCDEF (λ 1, and λ 2) " expression is connected with λ based on λ 1 connects A-B-C-D-E-F, and indication λ 1 and λ 2 ripple on node A, under node F ripple.
As shown in Figure 1, carry λ 3 and λ 4 ripple on node D of new business, through node E, ripple under node F.Node D, E and F obtain based on the wavelength connection relationship information DEF of λ 3 and λ 4 (λ 3, and λ 4), and concrete steps and front embodiment describe similar, repeat no more herein.

To sum up, by the technical scheme that adopts the invention described above embodiment to describe, each node can automatic acquisition based on the wavelength connection relationship information of each wavelength, need not use artificial manual operation, effectively save wavelength and connect the time of safeguarding, operating efficiency is greatly improved, and has realized the high reliability maintenance that wavelength connects, and avoids affecting the normal transmission of business in network.
For previously described another embodiment, need to prove at this, node D also can send the signaling message of wavelength connection relationship simultaneously to another one adjacent node C when sending signaling message to adjacent node E.Node C is after receiving this signaling message, and the wavelength that can identify self place connects whether belong to the wavelength information of carrying in this signaling message; If so, node C will send new signaling message to adjacent node B, and the identification information of node C has been carried in this new signaling message increase; If not, node C directly abandons this signaling message.Perhaps, node C is after receiving this signaling message, the wavelength at None-identified self place connects whether belong to the wavelength information of carrying in this signaling message, node C can continue to forward this signaling message to the adjacent node B of node C, until whether the circuit that the wavelength that has node can identify self place connects belongs to the wavelength information of carrying in this signaling message.Unrestricted transmission for fear of useless signaling described above, can certain specific sign be set to believing modern message, for example, when signaling message is every can't carry out the node of above-mentioned identification through one the time, this sign adds 1, after sign is increased to certain predefined numerical value, abandon signaling message.
In addition, as shown in Figure 1, wavelength is ripple on node A and node D respectively, in front on the basis of described embodiment, can set in advance the time (for example sending once in every 1 hour) that periodically sends signaling message on node A and/or node D, namely when surpassing the time that sets in advance, resend this signaling message.Also can be on the basis of setup times, increase maximum number of times (for example, arranging 3 times) that transmission is set, namely when transmission times when setting in advance, stop sending this signaling message.
Another embodiment of the present invention, according to aforesaid technical scheme, node A, B, C and D obtain and preserved wavelength connection relationship information ABCD based on λ 3 and λ 4, and (λ 3, λ 4), when certain wavelength falls ripple, take Fig. 6 as example, illustrate how node obtains the process of the wavelength connection relationship information of renewal.
A kind of situation, whether active node and passive node can both be identified wavelength and exist, automatically the wavelength connection relationship information of renewal preservation itself.For example, after λ 4 fell ripple, deletion was based on the wavelength connection relationship information of λ 4 automatically respectively for node A and D, and namely node A and D obtain the wavelength link information ABCD (λ 3) that information after renewal is based on λ 3.In like manner, Node B and C also can delete respectively the wavelength connection relationship information based on λ 4 automatically, and namely Node B and C obtain the wavelength link information ABCD (λ 3) that information after renewal is based on λ 3.
