Embodiment
For monitoring capacity and the fault management ability of raising system, system is refine to each bar physical channel to monitoring of the connectedness of MAC link and fault management to ethernet physical layer.In the embodiment of the invention, communicator generates effective physical layer operations management maintenance information, and it is added in the data flow to be sent; And be sent to and described logical channel physical channel one to one, and the data flow of the described VALIDPHYOAM of carrying information is sent to the recipient by this physical channel from the data flow that at least two logical channels will be carried VALID PHYOAM information.
Specific embodiments of the present invention is described in detail below in conjunction with accompanying drawing.
In the embodiment of the invention, between distribution sublayer of communicator physical layer (Reconciliation layer) and Physical Coding Sublayer (PCS layer), a device that is used to handle physical layer OAM overhead is set, is called the PHYOAM device.
In actual applications, the PHYOAM information that defines in the physical layer comprises idle physical layer operations management maintenance IDLE PHYOAM information and effective physical layer operations management maintenance VALID PHYOAM information, wherein, VALID PHYOAM information comprises broadcast physical layer oam BROADCAST PHYOAM information that sends with the forms of broadcasting and the logical channel physical layer operations maintenance management LANE PHYOAM information that sends with the logical channel form.
When only needing to send BROADCAST PHYOAM information, consult shown in Fig. 3 A, between Reconciliation layer in the communicator physical layer and the physical layer PCS layer PHYOAM device A1 is set, PHYOAM device A1 comprises first generation module 300, first receiver module, 301, the first processing modules 302, second processing module 303 and first sending module 304.
The sub data flow that first sending module 304 is used for carrying BROADCAST PHYOAM information is sent to the recipient from logical channel; All be provided with the first corresponding sending module 304 in each logical channel.
Based on above-mentioned PHYOAM device A1, to consult shown in Fig. 3 B, in the present embodiment, the detailed process of the first method of management ethernet physical layer OAM overhead is as follows:
Step S300:PHYOAM device A1 receives data flow to be sent from the Reconciliation layer.
Step S301:PHYOAM device A1 adds IDLE PHYOAM information in the data flow that receives.
In actual applications, in order to reduce the influence of the data message that data flow is carried, sometimes need to control the data length of the IDLE PHYOAM information of interpolation, for example, consult shown in Fig. 3 C, PHYOAM device A1 adds the IDLE PHYOAM information that accounts for entire stream data length 8% in the data flow that receives.
Step S302:PHYOAM device A1 judges whether to exist the BROADCASTPHYOAM information (promptly judging whether to exist the BROADCAST PHYOAM information of generation) of needs transmission, if then carry out step S303; Otherwise, carry out step S307.
The data flow that step S303:PHYOAM device A1 will carry IDLE PHYOAM information according to the logical channel number is divided into the sub data flow of respective logic number of active lanes.
For example, consult shown in Fig. 3 D, the logical channel number is 10 o'clock, the data flow that PHYOAM device A1 will carry 8% IDLE PHYOAM information is divided into 10 sub data flows, all carry 8% IDLE PHYOAM information in every sub data flow, wherein, the flow of every sub data flow can be identical, also can be different.
Step S304:PHYOAM device A1 replaces with the part or all of IDLEPHYOAM information of carrying in every sub data flow the BROADCAST PHYOAM information of generation.
In actual applications, if the data length of the BROADCAST PHYOAM information that generates is not less than the data length of the IDLE PHYOAM information of carrying in the data flow, then all replace; If, then carrying out part less than the data length of the IDLEPHYOAM information of carrying in the sub data flow, replaces the data length of the BROADCAST PHYOAM information that generates.
Each sub data flow that step S305:PHYOAM device A1 will carry BROADCAST PHYOAM information is distributed to relative logic channel.
Because the number of sub data flow equals the logical channel number, therefore, all has a sub data flow that carries BROADCAST PHYOAM information to be sent in every logical channel.
Each sub data flow that step S306:PHYOAM device A1 will carry BROADCAST PHYOAM information is sent to the recipient from relative logic channel.
Each sub data flow that step S307:PHYOAM device A1 will not carry BROADCAST PHYOAM information is sent to the recipient from relative logic channel.
When not having the BROADCAST PHYOAM information of generation, each sub data flow that PHYOAM device A1 will not carry BROADCAST PHYOAM information is sent to the recipient from relative logic channel, this does not carry and carries data message and IDLEPHYOAM information in the BROADCAST PHYOAM inter-area traffic interarea.
Because the number of logical channel and physical channel is one to one, therefore, PHYOAM device A1 is sent to the corresponding physical passage with each sub data flow earlier from relative logic channel, by each physical channel each sub data flow is sent to the recipient again, all transmit sub data flow in following examples in this manner, repeat no more.
In the above-described embodiments, each sub data flow that carries BROADCAST PHYOAM information sends simultaneously, owing in every logical channel, all transmitted identical BROADCAST PHYOAM information, therefore under the situation of partial logic channel failure, in the logical channel that PHYOAM device A still can never lose efficacy BROADCAST PHYOAM information is sent to the recipient, like this, just improved usage factor of system resource to a certain extent, simultaneously, because the logical channel that lost efficacy still can not continue to use, therefore, system can continue ethernet physical layer OAM expense is monitored and fault management, like this, just improved the monitoring capacity and the fault management ability of system to a certain extent to ethernet physical layer OAM expense.
On the other hand, consult shown in Fig. 3 E, also can adopt PHYOAM device A2 to finish identical flow process in the foregoing description.PHYOAM device A2 first generation module 300, first receiver module, 301, the eight processing modules 305 and first sending module 304.
The 8th processing module 305 is used for according to the logical channel number data flow to be sent being divided into the sub data flow of respective logic number of active lanes, and adds IDLE PHYOAM information and/or BROADCAST PHYOAM information in each sub data flow.
If the data length of the BROADCAST PHYOAM information that generates has reached setting threshold, for example, reach 8% of each sub-stream data length, then the 8th processing module 305 is just no longer added IDLE PHYOAM information in each sub data flow.
The sub data flow that first sending module 304 is used for carrying IDLE PHYOAM information and/or BROADCASTPHYOAM information is sent to the recipient from logical channel.
Use PHYOAM device A2 when the recipient sends BROADCAST PHYOAM information, can realize identical technique effect, do not repeat them here.
Be different from above-mentioned situation, when only needing to send LANE PHYOAM information, consult shown in Fig. 4 A, between Reconciliation layer in the communicator physical layer and the thing PCS layer PHYOAM device B is set, PHYOAM device B comprises that second generation module 400, second receiver module, 401, the three processing modules 402, manage the module 403 and second sending module 404 everywhere.
The 3rd processing module 402 is used for adding IDLE PHYOAM information in data flow to be sent, and be divided into the sub data flow of respective logic number of active lanes, and each sub data flow is distributed in the relative logic channel according to the data flow that the logical channel number will carry IDLE PHYOAM information.
Manages module 403 everywhere is used for the part or all of IDLE PHYOAM information that sub data flow carries is replaced with LANE PHYOAM information; All be provided with corresponding the in each logical channel and manage module 403 everywhere.
The sub data flow that second sending module 404 is used for carrying LANE PHYOAM information is sent to the recipient from logical channel; All be provided with the second corresponding sending module 404 in each logical channel.
Based on above-mentioned PHYOAM device B, to consult shown in Fig. 4 B, in the present embodiment, the detailed process of the second method of management ethernet physical layer OAM overhead is as follows:
Step S400:PHYOAM device B receives data flow to be sent from the Reconciliation layer.
Step S401:PHYOAM device B adds IDLE PHYOAM information in the data flow that receives.
Equally, for fear of influencing the data message that data flow is carried, need to control the data length of the IDLEPHYOAM information of interpolation sometimes.
The data flow that step S402:PHYOAM device B will carry IDLE PHYOAM information according to the logical channel number is divided into the sub data flow of respective logic number of active lanes; All carry IDLE PHYOAM information in every sub data flow.
Each sub data flow that step S403:PHYOAM device B will carry IDLE PHYOAM information is distributed in the relative logic channel.
Step S404:PHYOAM device B judges the LANE PHYOAM information (promptly judging the LANE PHYOAM information that whether has generation in each logical channel) that whether exists needs to send in each logical channel, and confirms to need to send the logical channel of LANE PHYOAM information.
Step S405:PHYOAM device B will replace with corresponding LANE PHYOAM information by the entrained part or all of IDLE PHYOAM information of sub data flow in each logical channel of confirming.
In actual applications, if the data length of the LANE PHYOAM information that generates is not less than the data length of the IDLE PHYOAM information of carrying in the data flow, then all replace; If, then carrying out part less than the data length of the IDLE PHYOAM information of carrying in the sub data flow, replaces the data length of the LANEPHYOAM information that generates.
On the other hand, if the LANE PHYOAM information that does not exist needs to send in the logical channel, then PHYOAM device B does not replace the IDLE PHYOAM information that any sub data flow carries.
Each sub data flow that step S406:PHYOAM device B will carry LANE PHYOAM information and not carry LANEPHYOAM information is sent to the recipient from relative logic channel.
In actual applications, after PHYOAM device B is issued to relative logic channel with each sub data flow, the transmission of each sub data flow in the respective logic passage is separate, for example, there are 10 logical channels among the PHYOAM device B, wherein, article 7, there is the LANEPHYOAM information that needs transmission in the logical channel, so, PHYOAM device B only will be issued to the 7th the entrained part or all of IDLE PHYOAM information of the sub data flow in the logical channel and replace with corresponding LANEPHYOAM information, and not handle the sub data flow that is issued in other logical channel.Like this, just can generate corresponding LANE PHYOAM information at each bar physical channel, and this physical channel is monitored and fault management according to response results, thereby will refine to each bar physical channel to the management of physical layer OAM overhead, improve monitoring capacity and fault management ability physical layer OAM overhead; On the other hand, owing to adopted the multi-logical channel pattern, therefore, under the situation of part physical channel inefficacy, still can the physical layer OAM overhead relevant information be delivered to the recipient, like this, just improve usage factor of system resource to a certain extent by the physical channel of not losing efficacy.
Be different from above-mentioned two kinds of situations, when both needing to send BROADCAST PHYOAM information, when also needing to send LANE PHYOAM information, consult shown in Fig. 5 A, between Reconciliation layer in the communicator physical layer and the thing PCS layer PHYOAM device C is set, PHYOAM device C is combined by PHYOAM device A1 and PHYOAM device B, comprise that the 3rd generates module 500, the 3rd receiver module 501, the five processing modules 502, the 6th processing module 503, the 7th processing module 504 and the 3rd sending module 505.
The 3rd generates module 500 is used to generate IDLE PHYOAM information, BROADCASTPHYOAM information and LANE PHYOAM information, wherein, the 3rd generation module 500 can regard that also first generation module 300 has added the function that generates LANE PHYOAM information and the functional module that obtains as.
It is identical that the 3rd receiver module 501 is identical with first receiver module, 301 functions, the 5th processing module 502 is identical with first processing module, 302 functions, the 6th processing module 503 is identical with second processing module, 303 functions, the 7th processing module 504 and is managed module 403 functions everywhere.
The sub data flow that the 3rd sending module 505 is used for carrying BROADCAST PHYOAM information and LANEPHYOAM information is sent to the recipient from logical channel; All be provided with the 3rd corresponding sending module 505 in each logical channel.
Based on above-mentioned PHYOAM device C, to consult shown in Fig. 5 B, in the present embodiment, the detailed process of the third method of management ethernet physical layer OAM overhead is as follows:
Step S500:PHYOAM device C receives data flow to be sent from the Reconciliation layer.
Step S501:PHYOAM device C adds IDLE PHYOAM information in the data flow that receives.
The BROADCAST PHYOAM information that step S502:PHYOAM device C determine to exist generates, and be divided into the sub data flow of respective logic number of active lanes according to the data flow that the logical channel number will carry IDLE PHYOAM information.
Step S503:PHYOAM device C replaces with the part or all of IDLEPHYOAM information of carrying in every sub data flow the BROADCAST PHYOAM information of generation.
Equally, if there is not the BROADCAST PHYOAM information of generation, then PHYOAM device C does not replace the IDLE PHYOAM information that any sub data flow carries.
Each sub data flow that step S504:PHYOAM device C will carry BROADCAST PHYOAM information is distributed to relative logic channel.
Step S505:PHYOAM device C confirms to exist the logical channel of the LANE PHYOAM information that generates.
Step S506:PHYOAM device C will replace with corresponding LANE PHYOAM information by the entrained part or all of IDLE PHYOAM information of sub data flow in each logical channel of confirming.
In actual applications, when PHYOAM device C adds LANE PHYOAM information, there are following two kinds of situations:
First kind of situation is: the LANE PHYOAM information that exists in the logical channel need not to send immediately.
So at this moment, if the sub data flow in the logical channel still carries IDLE PHYOAM information, and the data length of the IDLE PHYOAM information that this sub data flow carries then replaces with LANEPHYOAM information with part IDLE PHYOAM information greater than the data length of the LANEPHYOAM information of correspondence; And if the sub data flow in the logical channel still carries IDLE PHYOAM information, and the data length of the IDLE PHYOAM information that this sub data flow carries is not more than the data length of corresponding LANEPHYOAM information, then whole IDLE PHYOAM information are replaced with LANEPHYOAM information, and no longer this sub data flow is carried BROADCAST PHYOAM information and replace.
Second kind of situation is: the LANE PHYOAM informational needs that exists in the logical channel sends immediately.
So at this moment, if the sub data flow in the logical channel still carries IDLE PHYOAM information, then the IDLE PHYOAM information that this sub data flow carries is replaced according to corresponding LANE PHYOAM information, and during less than the data length of corresponding LANE PHYOAM information, the part or all of BROADCAST PHYOAM information of carrying in this sub data flow is replaced with LANE PHYOAM information at the data length of IDLE PHYOAM information.
Present embodiment is to be that example describes with a kind of in the above-mentioned situation.
Equally, if there is not the LANE PHYOAM information of needs transmissions in the logical channel, then the PHYOAM device B IDLE PHYOAM information of sub data flow in this logical channel not being carried or/and BROADCAST PHYOAM information replace.
Each sub data flow that step S507:PHYOAM device C will carry BROADCAST PHYOAM information and/or LANE PHYOAM information is sent to the recipient from relative logic channel.
In the above-described embodiments,, also can reach same technique effect, not repeat them here if PHYOAM device C is combined by PHYOAM device A2 and PHYOAM device B.
On the other hand, above-mentioned all embodiment all are applicable to the situation of single logical channel, also repeat no more at this.
In sum, in the embodiment of the invention, PHYOAM device in the communicator replaces with effective PHYOAM information with the part or all of IDLE PHYOAM information of adding in data flow to be sent, and the data flow that will carry effective PHYOAM information by two logical channels at least is sent to the recipient.Like this, system just can be refined to each physical channel to the monitoring and the fault management of ethernet physical layer OAM expense, thereby has improved monitoring capacity and the fault management ability of system to ethernet physical layer OAM expense to a certain extent; On the other hand, owing to adopt the multi-logical channel pattern, therefore, under the situation of part physical channel inefficacy, still can the physical layer OAM overhead relevant information be delivered to the recipient, like this, just improve usage factor of system resource to a certain extent by the physical channel of not losing efficacy.
