Under normal circumstances, the Sequence in the ConWord territory of each PWE3 message and CepHeader territory
Information (i.e. Sequence value, sequential value) is incremented by order, PWE3 detected when PTN device receives side
The Sequence information of message is not sequentially (to be incremented by the most continuously), at this moment there may be a variety of feelings
Condition, such as, big than previous message of the Sequence value of later message in two continuous P WE3 messages,
But be not difference 1, or little than previous message of the Sequence value of later message；Three continuous print
In PWE3 message, the Sequence value of second message is that exceptional value (is probably in data transmission procedure even existing number
According to mistake, be not real packet loss), the Sequence value of the 3rd message than big the two of first message,
It it is the relation being incremented by continuously；In the range of a period of time, Sequence value is not had to be incremented by order.
Therefore, in view of the presence of multiple situation, when the Sequence value receiving PWE3 message be not sequentially time,
Represent that the message received has been likely to occur packet loss or many bags or the situation of wrong bag.
The device sketch of the PTN device packet loss statistics that Fig. 8 embodiment of the present invention provides, Fig. 9 embodiment of the present invention
The Sequence comparator processor device sketch provided, as shown in Figure 8 and Figure 9, including:
1. receive packet check module, the Sequence value of the message of reception can be extracted；
2.CPU configures module, it is achieved configure the attribute of the message of reception by Pwlabel；
3. first memory, the content of storage is the Sequence value of current message；
4. second memory, the content reflecting history of storage receives the message of continuous Sequence value
The number of the message of Sequence value and discontinuous Sequence value；
5.Sequence comparator processor, it is achieved the output of first memory and second memory is compared, according to
Comparable situation completes packet loss statistics.Specifically, it is assumed that first memory is output as Sequence1, second
Memorizer is output as Sequence2, Sequence comparator processor and compares Sequence1 and Sequence2.
If Sequence1 is equal to Sequence2, the difference that both obtain after subtracting each other is 0, represents sequence of message number
(i.e. Sequence value) is continuous, and message is not lost, and does not adds up；If Sequence1 deducts
The difference of Sequence2 is more than N (arranging N=4096 here), represents that message dropping is too much, needs to report PWE3
Message dropping alerts, and does not do packet loss statistics；Other situation, Sequence1 deducts the difference of Sequence2,
Loss as current message is added up, and is stored in the 3rd memorizer, and now, Sequence comparator processor is by institute
The loss statistics of the current message obtained is added with at front statistical value, obtains total message dropping statistics.
The present invention utilizes subtractor the content of first memory and the content of second memory to be subtracted each other to obtain packet loss
Statistics.First memory and second memory are all stored by E1 time slot or VC time slot, and first memory is used
Sequence value (i.e. actual sequence value) in the current message that storage receives.Therefore, arrive when next message
When coming, read the content of first memory, so that it may obtain the Sequence value of a upper message.Second storage
The content of device storage is had ready conditions restriction: first determine whether the Sequence value of current message and a upper message
Whether Sequence value is relation sequentially, if relation sequentially is then by current message
Sequence value stores to second memory；If not relation sequentially, then it represents that message
Sequence value is discontinuous, then read the content of second memory, makees after then adding 1 by this content
For preferable Sequence value, second memory of restoring (adds 1 expression and have received a message, but receive
Be the message of discontinuous Sequence value), therefore the content of second memory storage reflects what history received
The number of the message of message continuous print Sequence value and discontinuous Sequence value.
Often receive a new PWE3 message, first memory will be updated, simultaneously according to receiving message
Sequence value determines how renewal second memory.Relatively the Sequence value of first memory output is (i.e.
The Sequence value of a upper message) and the Sequence value of current message, when judging that Sequence value is even
When continuing incremental, in first memory and second memory are exported by the subtractor of Sequence comparator processor
Appearance is subtracted each other, and i.e. can get the packet loss statistics of PWE3 message.But can not receive the Sequence being incremented by continuously always
In the case of the message of value, just can not get the packet loss statistics of message, enable therefore to start packet loss statistics, this
Embodiment receive continuous N (M could be arranged to 1,2,3,4,5 ... .) the Sequence value of individual message
When being all discontinuous, the content of second memory utilizes the Sequence value of m-th message to update, and exists simultaneously
In this moment, the content carrying out first memory and second memory is subtracted each other.
Owing to Sequence value is by 16bit cycle accumulor, if the Sequence value of first memory storage
Less than the Sequence value of second memory storage, it is understood that there may be the most several situations:
If 1. the Sequence value of first memory storage is 16 ' h0, the Sequence of second memory storage
Value is 16 ' hffff, and the message number in this case lost is probably 0 or 65536 or 131072 (i.e.
65536+65536=131072) or more.
If 2. the Sequence value of first memory storage is 16 ' h3, the Sequence of second memory storage
Value is 16 ' hffff, and the message number in this case lost is probably 3 or 65539 or 131075
(65539+65536=131076) more.
Therefore, directly carry out subtracting each other the packet loss statistics meeting obtained by the output valve of first memory and second memory
There is a lot of probability.For statistics network packet loss more accurately, it is ensured that the uniqueness of packet loss statistics, the present invention is only
Consider the Sequence value difference scope of first memory and second memory 0 to N (N could be arranged to 0～
Any one value in 65535) situation.When actually Network Packet Loss is more than N number of message, can adopt
Client is notified by other means.Assuming N=4096, PTN device receives a PWE3 message every 125us, that
Lose the time that 4096 messages need: 4096x125us=512ms.Therefore, arrange a 512ms time
Between window, when being all not received by PWE3 message in 512ms time range, then report PWE3 message dropping to accuse
Alert, at this moment packet loss statistical value is without reference to meaning.
It is embodied as step:
The first step: in the reception side entrance of PTN device, the legitimacy of the PWE3 message that detection receives, from conjunction
The message of method extracts Pwlabel and Sequence, and by illegal packet loss.
Second step: CPU presses the attribute of Pwlabel configuration message.
To CES business, CPU E1 timeslot number as belonging to the CES PWE3 message that Pwlabel configuration receives；
To CEP business, CPU VC timeslot number as belonging to the CEP PWE3 message that Pwlabel configuration receives.
With Pwlabel attribute of query message from CPU configures of reception message, obtain current message corresponding
E1 time slot or VC time slot.
3rd step: use first memory, by the Sequence of the message that E1 time slot/VC time slot storage receives
Value.
Whenever receiving a new PWE3 message, it is required for updating first memory.
4th step: often receive a new PWE3 message, reads the first storage with E1 time slot or VC time slot
Device, obtains the output valve of first memory, namely goes up the Sequence value of a message.Then by first
The output valve of memorizer and the current Sequence value receiving message compare, it may be judged whether be incremented by relation.As
Fruit is incremented by, and by E1 time slot/VC time slot, the Sequence of current message is stored in second memory.
If not incremental, the output valve of second memory added 1 and stores again.When receiving continuous N message
The relation that Sequence value is not incremented by, adds 1 the output valve of first memory and is then stored into the second storage
In device.
5th step: whenever receiving the message of continuous Sequence value or receive continuous N message
When Sequence value is all discontinuous, read output valve Sequence1 of first memory and second memory
Output valve Sequence2, both do subtraction.When Sequence1 is equal to Sequence2, represent sequence
Number continuously, message is not lost；When the difference of Sequence1 and Sequence2 is more than 16 ' h0fff, no
Do packet loss statistics, and report message dropping to alert, to notify client；Otherwise, by Sequence1 and Sequence2
Difference lose statistical result as current message.
