For ease of the understanding to the embodiment of the present invention, it is further explained below in conjunction with accompanying drawing with specific embodiment
Bright, embodiment does not form the restriction to the embodiment of the present invention.
Describe the processing method for the message that the embodiment of the present invention one provides in detail by taking Fig. 1 as an example below, Fig. 1 is real for the present invention
The process flow figure of the message of example offer is applied, subject of implementation is the network equipment in embodiments of the present invention.As shown in figure 1,
The embodiment specifically includes following steps：
Step 110, the network equipment receive the first message and the second message, and the time for receiving first message connects for first
Between time receiving, the time for receiving second message receives the time for second.
Specifically, the current data or voltage data of transformer collection cable run, transformer is to being connected with itself
MU sends the current data or voltage data of collection.After MU receives current data or voltage data, to current data or
Person's voltage data carries out D/A switch, generates SV messages, and the message includes the current data or voltage after digital-to-analogue conversion
A data in data.The network equipment can be connected with multiple MU, and each MU in multiple MU is according to coupled mutual inductance
The current data or voltage data of device collection continue to send message to relay protector.The network equipment receives these MU transmissions
Multiple messages.The embodiment of the present invention with any two message in this multiple message, i.e. the first message and the second message, exemplified by
Illustrate the operation of the network equipment.The network equipment is to each message in this multiple message according to described in the embodiment of the present invention
Mode forwards.In embodiments of the present invention, current data or electricity are carried according to the different type of transformer, first message
Any data in data is pressed, likewise, the second message carries any data in current data or voltage data.
For example, a transformer in the multiple transformers being connected with a MU in multiple MU is current transformer (English
Text：Current Transformer, abbreviation：CT), the current transformer sends the current data of collection to the MU, and MU is received
After current data, D/A switch is carried out to current data, generates SV messages, the message carries the electric current after digital-to-analogue conversion
Data.
First message and the second message are SV messages.
The time that the network equipment receives the first message receives the time for first, and the time for receiving the second message receives for second
Time.
Step 120, the network equipment cache first message and the second message.
Optionally, the network equipment is by the first message and the second message, in the buffer queue for sequentially depositing the network equipment,
In buffer queue, the first message and the second message are cached.
Step 130, when reaching first and sending the time, the network equipment sends first message, first hair
The time is sent to add delay value for the described first reception time, the delay value is default fixed value.
Specifically, the network equipment determines that send the first message first sends the time, and described first sends the time as first
The reception time adds delay value, and the delay value is default fixed value.
When reaching for the first transmission time, the network equipment sends the first message to relay protector.
In one implementation, the network equipment determines that send the first message first sends the time by timer.Net
Network equipment formerly sets timer, and the timed length of timer is delay value (for example, 50 microseconds), is receiving the first message,
And when the first message is deposited into buffer queue, the network equipment starts timer function, often cross 1 microsecond timer and subtract 1, when timing
When device is kept to 0, the network equipment is determined to reach for the first transmission time, and the first message is sent to relay protector.
In another implementation, the network equipment receives the time by first, it is determined that sending the first hair of the first message
Send the time.
The network equipment obtains the first reception time for receiving the first message, is worth to the first reception time plus delay
Send the first of the first message and send the time, and record first and send the time.The network equipment periodically judges whether to have reached
First sends the time, and when reaching for the first transmission time, the network equipment sends the first message to relay protector.
When not up to first sends the time, the network equipment continues to cache the first message.
Step 140, when reaching second and sending the time, the network equipment sends second message, second hair
The time is sent to add the delay value for the described second reception time.
Specifically, the network equipment determines that send the second message second sends the time, and described second sends the time as second
The reception time adds delay value, and the delay value is default fixed value.
When reaching for the second transmission time, the network equipment sends the second message to relay protector.
In one implementation, the network equipment determines that send the second message second sends the time by timer.
The network equipment formerly sets timer, and the timed length of timer is delay value (for example, 50 microseconds), is being received
Second message, and when the second message is deposited into buffer queue, the network equipment starts timer function, often crosses 1 microsecond timer
Subtract 1, when timer is kept to 0, the network equipment is determined to reach for the second transmission time, and the second message is sent to relay protector.
In another implementation, the network equipment receives the time by second, it is determined that sending the second hair of the second message
Send the time.
The network equipment obtains the second reception time for receiving the second message, is worth to the second reception time plus delay
Send the second of the second message and send the time, and record second and send the time.The network equipment periodically judges whether to have reached
Second sends the time, and when reaching for the second transmission time, the network equipment sends the second message to relay protector.
When not up to second sends the time, the network equipment continues to cache the second message.
Because the network equipment is before the first message and the second message is sent, it is each packet buffer identical delay value, makes
The network equipment is sending the first message and during the second message, still according to reception when receiving the first message and the second message when
Between be spaced and be transmitted, reduce shake, also cause relay protector to be accurately received message, and then judge cable run
Electric power thus supplied, realize the relay protection to power circuit.
Alternatively, before step 120 of the embodiment of the present invention, in addition to the network equipment determines to receive the first message and second
The step of interface index of the physical interface of message, by the step, the network equipment can be made to cache the first message and the second report
Wen Shi, according to interface index, the first message and the second message are deposited in buffer queue corresponding with interface index respectively, entered
And simplify the complexity of distribution spatial cache.Comprise the following steps that：
The network equipment determines to receive the first interface numbering of the physical interface of first message；
The network equipment determines to receive the second interface numbering of the physical interface of second message；
Specifically, after the network equipment receives the first message and the second message, determine that the physics for receiving the first message connects respectively
The first interface numbering of mouth, it is determined that receiving the second interface numbering of the physical interface of the second message.When the first message and second are reported
When text is that same physical interface is sent, first interface numbers (for example, being all 01) identical with second interface numbering；When the first report
When text and the second message are that different physical interfaces are sent, first interface numbering is different (for example, first interface with second interface numbering
Numbering is 01,03) second interface numbering is.
Correspondingly, the step 120 is specially：Numbered according to first interface, the network equipment by the first message deposit into
In buffer queue corresponding to first interface numbering；Numbered according to second interface, the network equipment deposits the second message into second
In buffer queue corresponding to interface index.
Specifically, number of the network equipment according to own physical interface or the number according to the MU being connected with itself, it is
Buffer queue corresponding to each physical interface or each MU establishments.When it is determined that receiving the first interface of the physical interface of the first message
During numbering (for example, first interface numbering is 01), then the first message is deposited into caching team corresponding with first interface numbering 01
In row；When it is determined that receiving the second interface numbering of the physical interface of the second message (for example, second interface numbering is 03), then will
Second message deposit with 03 corresponding buffer queue of second interface numbering.Cached by the way that the message of reception is corresponded to, can letter
Change the complexity of distribution spatial cache, the message of reception is rapidly introduced into buffer queue and cached.
The network equipment also can only establish a buffer queue, and the message received is all deposited in buffer queue；Or
Person, the network equipment distribute spatial cache for message temporarily when receiving message.
In embodiments of the present invention, the network equipment can be interchanger or passive optical network PON equipment.
When the network equipment is interchanger, then step 110 can be performed to step 140 according to hereinbefore described process.
When the network equipment is PON equipment.Then before step 110 caches the first message, in addition to PON equipment judges the
One receives the time whether in the current polling time slot of PON equipment, and according to the step of judged result the first message of caching.Specifically
Step is as follows：
The PON equipment judges that described first receives the time whether in the current polling time slot of the PON equipment；
If the first reception time is in the current polling time slot of the PON equipment, the PON equipment caching
First message；
If described first receives the time outside the current polling time slot of the PON equipment, the PON equipment determines institute
The the first active delay time and the second active delay time of the first message are stated, according to the first active delay time and second
Active delay time, cache first message；
Wherein, the first active delay time is that the PON device pollings connect to the physics for receiving first message
Time at mouthful subtracts described first and receives the time；
The second active delay time is that the delay value subtracts the first active delay time.
The operation principle of PON equipment is sketched herein.PON equipment includes optical line terminal (English：Optical Line
Terminal, abbreviation：OLT) and multiple optical network units are (English：Optical Network Unit, abbreviation：ONU).OLT with
Multiple ONU connections.
In uplink communication, PON equipment is using time division multiple acess (English：Time Division Multiple Access,
Abbreviation：TDMA) mode transmitting message.That is OLT is in a polling cycle, each ONU of poll, and being averaged for each ONU successively
Distribute polling time slot.ONU receives the physical interface of message as PON equipment.The polling time slot that each ONU distributes in OLT (is specified
Period) in OLT send message, OLT receive message.If the wheel that a certain ONU (for example, ONU1) is currently distributed in OLT
Ask in time slot and do not send message to OLT in time, then OLT no longer receives the message of ONU transmissions, and it is next to continue poll
ONU (ONU2), when OLT is polled to ONU1 again, ONU1 sends message to OLT again.
Specifically, after PON equipment receives the first message, judge whether the first reception time in PON equipment worked as front-wheel
Ask in time slot, if the first reception time was in the current polling time slot of PON equipment, when PON equipment receives according to first
Between, the first message is cached, that is, performs step 230.
If first receives the time outside the current polling time slot of PON equipment, PON equipment determines the first of the first message
Active delay time and the second active delay time, according to the first active delay time and the second active delay time, caching the
One message.
For example, it is assumed that the first reception time for receiving the first message is W, PON equipment is polled to the report of reception first again
Time at the physical interface of text is U, the default fixed value X of delay value, then the first active delay time is U-W；Second actively
Delay time is X- (U-W).
PON equipment caches the first message, specifically, slow according to the first active delay time and the second active delay time
The time deposited is that the first active delay time adds the second active delay time, that is, the time cached is：U-W+X- (U-W)=X,
It that is to say, the delay value X that PON equipment is fixed to the first packet buffer.
It is understood that the reception time for each message that PON equipment interconnections are received does above-mentioned judgement processing, example
Such as, also do above-mentioned judgement to the second reception time for receiving the second message to handle, no longer repeat herein.
Further, in embodiments of the present invention, each ONU is connected with a MU, and ONU receives the message of MU transmissions,
And send message to OLT in polling time slot.
ONU1 sends the first message in OLT distribution polling time slots to OLT, after OLT receives the first message, judges first
The time is received whether in ONU1 current polling time slot, if the first reception time was in ONU1 current polling time slot,
Then OLT receives the time according to first, caches the first message, that is, performs step 230.
If first receives the time outside ONU1 current polling time slot, OLT determines that the first active of the first message is prolonged
When time and the second active delay time, according to the first active delay time and the second active delay time, cache the first message.
For example, it is assumed that the first reception time that ONU1 receives the first message is W, OLT is polled to ONU1 time again
For U, the default fixed value X of delay value, the time is received outside current polling time slot because ONU1 receives the first of the first message, then
ONU1 by the first packet buffer in ONU1, wait OLT again poll when, to OLT send the first message, the first message is in OUN1
In cache-time be the first active delay time；Because the first message has cached (U-W) at ONU1, then OLT is connecing
After receiving message, the time that the first message cached is subtracted with delay value, obtains the cache-time of the first message in the olt as the
Two active delay times,
Therefore, the time of caching of first message in PON equipment is that the first active delay time prolongs plus the second active
When the time, that is, the time cached is：U-W+X- (U-W)=X, that is to say, the delay value X that OLT fixes to the first packet buffer.
Therefore, the processing method of application message provided in an embodiment of the present invention, first report of the network equipment to reception are passed through
Text and the second message carry out caching process, and when reaching the transmission time of each message, the network equipment sends message, sends the time
Delay value is added to receive the reception time of message, delay value is default fixed value.Because the network equipment is sending each report
Wen Qian, the delay value fixed for each packet buffer so that the network equipment is when sending each message, still according to reception message
When reception time interval be transmitted, reduce message shake, also cause relay protector can be accurately received message, and then
Judge the electric power thus supplied of cable run, realize the relay protection to power circuit.
