Description

A kind of service data transmission method and device

Technical field

The present invention relates to field of communication technology, more particularly to a kind of service data transmission method and device.

Background technology

Business datum can be transmitted by Optical Transmission Network OTN (Optical Transport Network, OTN).In the transmission, industry Business data are mapped in optical channel Payload Unit (Optical channel Payload Unit, OPUk), by business number After increase Optical Channel Data Unit-k (Optical channel Data Unit, ODU) expense, become low order optical channel data Unit ODUk；Multichannel low order ODUk can be multiplexed into the OPUk of higher rate, become high-order OPUk, by high-order OPUk increases Become high-order ODUk after ODU expenses.

To be mapped to business datum all the way to be transmitted on low order ODUk all the way in general application, receiving terminal into Recover the business datum after the parsing of row data.When transmission is mutually related, (this multi-channel service data may phase for multi-channel service data When together, it is also possible to different), usually this multi-channel service data are reached with the time interval between the time of client, namely relatively Delay has strict demand.To ensure relative delay demand, the larger caching of capacity usually is disposed in the receiving terminal of OTN, The business datum of reception is first cached, after the multi-channel service data that are mutually related all reach, then is taken out from the caching Each road business datum sends jointly to client.

In this manner, it is necessary to which there is the industry of relative delay requirement on the caching Lai Duige roads of receiving terminal deployment large capacity The business datum first reached in business data is temporarily stored.Ruo Ge roads have in the business datum of relative delay requirement, have All the way business datum reach receiving terminal time delay it is longer, then just have to wait for road business datum reach receiving terminal it Afterwards, the business datum that this several road could be had to relative delay requirement is sent together；If have all the way business datum due to transmission therefore Barrier can not reach receiving terminal, then receiving terminal just needs to cache the other roads for having relative delay requirement with the road business datum always Business datum, and the business datum of caching can not be sent.Obviously, the business data transmission reliability under this mode compared with It is low；Also, it in this manner, can not in time be discharged in the caching of the large capacity of receiving terminal deployment, cause receiving terminal to delay It is higher to be saved as this.

Embodiment

The basic thought of the embodiment of the present invention is：In Optical Transmission Network OTN OTN, first reception is write per business datum all the way In the corresponding spatial cache of road business datum；It is empty from the corresponding caching of each road business datum required with relative delay Between it is middle taking-up business datum merge, the business datum all the way after being merged, and send merging after business datum all the way. After the embodiment of the present invention, the business datum that each road can be had to relative delay requirement is bound into business datum progress all the way Send, without absorbing the relative delay between each road business datum in the caching of receiving terminal increase large capacity, save The caching cost of receiving terminal.Also, since each road has the business datum of relative delay requirement can be in OTN as industry all the way Business data are transmitted, so as to reduce the relative delay of each road business datum on the transmit path, improve transmission reliability.

The embodiment of the present invention is described in further detail with reference to Figure of description.

Embodiment one

As shown in Figure 1, the service data transmission method flow chart provided for the embodiment of the present invention one, comprises the following steps：

S101：Reception is write in the corresponding spatial cache of road business datum per business datum all the way.

Here, business datum self-generating end is sent to the transmitting terminal of Optical Transmission Network OTN OTN., will be per business all the way in transmitting terminal Data are write in its corresponding small caching, after each road business datum with relative delay requirement all reaches transmitting terminal, are based on S102~S103 carries out the overall scheduling of each road business datum.

S102：Business datum is taken out from the corresponding spatial cache of each road business datum required with relative delay Merge, the business datum all the way after being merged；Any two in each road business datum with relative delay requirement The time interval that road business datum was reached between the time of client needs to be less than preset duration.

Specifically, after each road business datum progress byte of taking-up is interleave, it is merged into business datum all the way；Wherein, often All the way in business datum each byte adjacent byte be other circuit-switched datas byte.

In specific implementation process, business datum merging can be carried out by the way of byte interleaves, will with realization as far as possible Binding mapping after each road business datum alignment, in this way, the relative delay between each road business datum can be reduced further.Such as Shown in Fig. 2, A roads business datum and B roads business datum merge by the way of byte interleaves, wherein A roads business datum The B1 bytes of B roads business datum are inserted into after A1 bytes, then, the A2 bytes of A roads business datum are inserted into after B1 bytes, in this way, real Show the merging of two-way business datum, and there was only the relative delay of a byte between two-way business datum.

S103：Send the business datum all the way after merging.

In S102~S103, it is thus necessary to determine that scheduling rates, in order to carry out each road business datum based on scheduling rates Overall scheduling (merge and send).Namely：From the corresponding spatial cache of each road business datum required with relative delay Middle taking-up business datum merges, including：

Can be that each road business datum with relative delay requirement determines an identical tune when carrying out overall scheduling Speed is spent, further to reduce the relative delay between each road business datum.In specific implementation, third gear tune can be pre-set Spend speed, be greater than successively from high to low each road business datum average traffic speed (or receive business datum entrance speed Rate) the first scheduling rates, equal to each road business datum average traffic speed the 3rd scheduling rates and less than each road business Second scheduling rates of the average traffic speed of data.Per business number all the way in each road business datum with relative delay requirement According to average traffic speed be identical, namely their overall service rates are consistent, simply it sometimes appear that certain road industry The burst increase or burst for data of being engaged in are reduced.

The embodiment of the present invention proposes the mode of following two definite scheduling rates：

Mode one：Based on to the data volume size in the corresponding spatial cache of each road business datum and preset data amount The comparable situation of size, to determine scheduling rates.

Specifically, the data volume size in the corresponding spatial cache of each road business datum, determines scheduling General scheduling rates when in each road business datum per business datum all the way, including：

When in the corresponding spatial cache of each road business datum, the data volume size at least one spatial cache More than preset data amount size, when the data volume size at least one spatial cache is less than preset data amount size, institute is determined In the absolute value of the difference of data volume size and preset data amount size in the corresponding spatial cache of Shu Ge roads business datum Maximum, according to the data volume size in the definite corresponding spatial cache of the maximum, determine scheduling rates.

In which once, the data volume size and preset data amount size of each road business datum of caching are compared first, If the data volume size of each road business datum of caching is both greater than preset data amount size, or except equal to preset data amount size Business datum outside, remaining is both greater than preset data amount size, then using first scheduling rates；If each road business of caching The data volume size of data is both less than preset data amount size, or in addition to equal to the business datum of preset data amount size, its Remaining both less than preset data amount size, then using second scheduling rates；If the data volume of each road business datum of caching is big It is small to be equal to preset data amount size, then using the 3rd scheduling rates, or first scheduling rates can also be used Or second scheduling rates (in this case, according to the first scheduling rates, may result in the data volume of each road business datum Size is both less than preset data amount size, then uses the second scheduling rates again, on the contrary, according to the second scheduling rates, may Cause the data volume size of each road business datum to be both greater than preset data amount size, then use the first scheduling rates again)；If caching Each road business datum in, some is less than preset data amount size, and some is more than preset data amount size, then according to and present count Scheduling rates are determined according to the caching situation of the business datum all the way of the maximum absolute value of the difference of amount size.

Alternatively, the data volume size in the definite corresponding spatial cache of the maximum, determines scheduling rates, Including：When the data volume size in the definite corresponding spatial cache of the maximum is more than preset data amount size, determine The scheduling rates are the first scheduling rates of the average traffic speed more than each road business datum；When determine described in most When being worth the data volume size in corresponding spatial cache greatly and being less than preset data amount size, determine the scheduling rates for less than institute Second scheduling rates of the average traffic speed of Shu Ge roads business datum.

In specific implementation process, when in each road business datum of caching, some is less than preset data amount size, and what is had is big When preset data amount size, can based on and preset data amount size difference maximum absolute value business datum all the way it is slow Situation is deposited to determine scheduling rates, if should and the business datum all the way of maximum absolute value of difference of preset data amount size cached Data volume size be more than preset data amount size, then using first scheduling rates, if the number of road business datum caching It is less than preset data amount size according to amount size, then using second scheduling rates.

Mode two：Directly by calculating the data volume size in the corresponding spatial cache of each road business datum with presetting Maximum in the absolute value of the difference of data volume size, to determine scheduling per the general scheduling rates of business datum all the way.

Specifically, the data volume size in the corresponding spatial cache of each road business datum, determines scheduling Speed, including：

According to the data volume size in the definite corresponding spatial cache of the maximum, scheduling rates are determined.

Further, the data volume size in the definite corresponding spatial cache of the maximum, determines scheduling speed Rate, including：When the data volume size in the definite corresponding spatial cache of the maximum is more than preset data amount size, really The fixed scheduling rates are the first scheduling rates of the average traffic speed more than each road business datum；Described in determining When data volume size in the corresponding spatial cache of maximum is less than preset data amount size, determine the scheduling rates be less than Second scheduling rates of the average traffic speed of each road business datum；When the definite corresponding spatial cache of the maximum In data volume size when being equal to preset data amount size, it is flat equal to each road business datum to determine the scheduling rates 3rd scheduling rates of equal service rate.

Under which two, the data volume size of each road business datum of caching and the difference of preset data amount size are determined Maximum in absolute value is big by the data volume size in the spatial cache of the relatively more corresponding maximum and preset data amount It is small, determine scheduling rates.For example if the data volume size in the spatial cache of the corresponding maximum is equal to preset data amount size (namely the maximum is 0, and the data volume size of each road business datum of caching is equal to preset data amount size), then using institute State the 3rd scheduling rates；If the data volume size in the spatial cache of the corresponding maximum is more than preset data amount size, adopt With first scheduling rates, if the data volume size in the spatial cache of the corresponding maximum is less than preset data amount size, Then use second scheduling rates.

Alternatively, the data volume size in the corresponding spatial cache of each road business datum, determines scheduling General scheduling rates when in each road business datum per business datum all the way, including：

In specific implementation process, to be damaged when there are business datum in each road business datum required with relative delay When, can be according to other road industry in addition to the business datum damaged in order not to influence the normal transmission of other road business datums The data volume size for data of being engaged in, to determine current scheduling rates.

Alternatively, described one after this method merges applied to the business data transmission in Optical Transmission Network OTN OTN, the transmission Road business datum, including：

, can be in optical channel data cell (ODUk) when at least business datum damages all the way for presence in OTN system Expense is indicated in subframe region, in order to which receiving terminal distinguishes the business datum damaged, and indicates business number to client According to the information damaged.Meanwhile the business datum after merging is mapped to ODUk payload sections.

Embodiment two

The embodiment two makees service data transmission method of the embodiment of the present invention to be further situated between from the angle of the receiving terminal of OTN Continue.Specific implementation repeats part with above-described embodiment one, repeats no more.

As shown in figure 3, being service data transmission method flow chart provided by Embodiment 2 of the present invention, comprise the following steps：

S301：Receive the business datum all the way after merging.

S302：Business datum all the way after the merging of reception is split, obtains splitting Hou Ge roads business datum.

Alternatively, the business datum all the way after the merging of reception is split, obtains splitting Hou Ge roads business datum, Including：

S303：Hou Ge roads business datum will be split and be sent to client.

Alternatively, this method is applied to the business data transmission in Optical Transmission Network OTN OTN, described to split Hou Ge roads business Data sending to client, including：

In specific implementation process, receiving terminal obtains its ODUk payload to the ODUk demappings of reception, to ODUk payloads into Row byte split obtains sending per business datum all the way.Meanwhile the expense of the ODUk of reception is parsed, confirm per business all the way The validity of data, namely be confirmed whether that there are business datum and to damage, if in the presence of at least business datum damages all the way, also need to Client, which is sent, indicates the information that at least business datum damages all the way.

The present invention program is described further below by a specific embodiment.

Embodiment three

As shown in figure 4, the service data transmission method flow chart provided for the embodiment of the present invention three, Fig. 5 is to correspond to therewith Transmission schematic diagram, comprise the following steps：

S401：Reception is write the corresponding spatial cache of road business datum by the transmitting terminal of OTN per business datum all the way In.

S402：Transmitting terminal according to relative delay requirement each road business datum in, in addition to the business network data damaged The corresponding spatial cache of other road business datums in data volume size, determining that scheduling is described has relative delay requirement Each road business datum in per business datum all the way when general scheduling rates；According to definite scheduling rates, from described each Business datum is taken out in the corresponding spatial cache of road business datum, merges, is closed by the way of byte interleaves Business datum all the way after and.

As shown in figure 5, in transmitting terminal, it may include the work(such as business datum receiving unit, buffer unit and overall scheduling unit Energy unit, business datum receiving unit handle the business datum of reception, produce (the instruction of business datum status indication information Whether business datum damages) write to overall scheduling unit, and by reception per business datum all the way in a spatial cache.It is slow The business datum that memory cell cache business data receipt unit is sent, and buffer status information is produced, including in spatial cache Buffer data size compares the deviation (and difference of preset data amount size) of preset data amount, and/or produces in spatial cache The comparative result (be more than/be less than/be equal to preset data amount size) of size between buffer data size and preset data amount.It is overall to adjust Spend unit to use after the merging of multi-channel service data by the way of byte interleaves, be mapped to ODUk payload areas, and by business datum State is mapped to expense domain.In receiving terminal, after the business datum all the way after the merging of reception is carried out byte split, through business number Sent according to transmitting element.If by parsing expense domain, determine in the presence of at least business datum damages all the way, then to send out to client Send and indicate this information that at least business datum damages all the way.

Here, the mode one of scheduling rates is determined：

When the data volume size in the corresponding spatial cache of each road business datum, to be all higher than preset data amount big It is small, or in the corresponding spatial cache of each road business datum, the data volume size in some spatial caches is more than default Data volume size, when the data volume size in some spatial caches is equal to preset data amount size, determines that the scheduling rates are More than the first scheduling rates of the average traffic speed of each road business datum；When each road business datum is corresponding Data volume size in spatial cache is respectively less than preset data amount size, or the corresponding caching sky of each road business datum Between in, the data volume size in some spatial caches is less than preset data amount size, the data volume size in some spatial caches During equal to preset data amount size, determine that the scheduling rates are the average traffic speed less than each road business datum the Two scheduling rates；When the data volume size in the corresponding spatial cache of each road business datum is equal to preset data amount During size, the first scheduling rates that the scheduling rates are the average traffic speed more than each road business datum are determined, or For the second scheduling rates of the average traffic speed less than each road business datum, or for equal to each road business datum 3rd scheduling rates of average traffic speed；When in the corresponding spatial cache of each road business datum, some cachings are empty Between in data volume size be more than preset data amount size, it is big that the data volume size in some spatial caches is less than preset data amount Hour, determines the difference of the data volume size and preset data amount size in the corresponding spatial cache of each road business datum Absolute value in maximum, when the data volume size in the definite corresponding spatial cache of the maximum is more than preset data When measuring size, the first scheduling rates that the scheduling rates are the average traffic speed more than each road business datum are determined, When the data volume size in the definite corresponding spatial cache of the maximum is less than preset data amount size, the tune is determined Spend the second scheduling rates that speed is the average traffic speed less than each road business datum.

Determine the mode two of scheduling rates：

According to the data volume size in the corresponding spatial cache of each road business datum, scheduling rates are determined, wrap Include：

Determine the data volume size and preset data amount size in the corresponding spatial cache of each road business datum Difference absolute value in maximum；Preset when the data volume size in the definite corresponding spatial cache of the maximum is more than During data volume size, the first scheduling speed that the scheduling rates are the average traffic speed more than each road business datum is determined Rate；When the data volume size in the definite corresponding spatial cache of the maximum is less than preset data amount size, institute is determined State the second scheduling rates that scheduling rates are the average traffic speed less than each road business datum；When the definite maximum When being worth the data volume size in corresponding spatial cache and being equal to preset data amount size, it is equal to described to determine the scheduling rates 3rd scheduling rates of the average traffic speed of each road business datum.

As shown in Fig. 6 (a), it is assumed that there are A, B two-way business, during original state a, the buffer data size of two-way business is impartial In preset data amount；If the first scheduling rates, since scheduling rates are bigger than inlet rate, the caching of two-way business are used at this time Data volume gradually decreases, and will jump to state b；If using the second scheduling rates again at this time, since scheduling rates are than entrance speed Rate is small, and the buffer data size of two-way business is gradually saved bit by bit, and will jump to state c.In specific implementation, when the caching of two-way business When data volume size is less than preset data amount size, using the second scheduling rates, so that the buffer data size of two-way business delays It is slow to increase, if on the contrary, the buffer data size size of two-way business is more than preset data amount size, using the first scheduling rates, with So that the buffer data size of two-way business is slowly reduced, by such process, the buffer data size of final two-way business is pre- If data volume oscillates about, state d is reached.

In Fig. 6 (a), the buffer status of two-way business datum is consistent.Fig. 6 (b)~(c) is the buffer status of two-way business Inconsistent but identical with the comparative result of preset data amount size situation.

As shown in Fig. 6 (b), during original state a, the buffer data size of A, B two-way business is equal to preset data amount；In shape During state b, business A, B produces data burst and increases, and the data burst increment of A is more than the data burst increment of B, at this time A industry The buffer data size of business is more than the buffer data size of B business.Due to the buffer data size of A, B business, to be both greater than preset data amount big It is small, using the first scheduling rates more than inlet rate.Since the average traffic speed of A, B two-way business is consistent, pass through After a period of time, c states can be reached, still use the first scheduling rates at this time, the buffer data size of final two-way business is default Data volume oscillates about, and reaches state d.

As shown in Fig. 6 (c), during original state a, the buffer data size of A, B two-way business is equal to preset data amount；In shape During state b, business A, B produces data burst and reduces, and the data burst decrement of B is more than the data burst decrement of A, at this time B industry The buffer data size of business is less than the buffer data size of A business.Due to the buffer data size of A, B business, to be both less than preset data amount big It is small, using the second scheduling rates less than inlet rate.Since the average traffic speed of A, B two-way business is consistent, pass through After a period of time, c states can be reached, still use the second scheduling rates at this time, the buffer data size of final two-way business is default Data volume oscillates about, and reaches state d.

Fig. 6 (d) is the buffer data size of the two-way business situation different from the comparative result of preset data amount size.

As shown in Fig. 6 (d), during original state a, the buffer data size of A, B two-way business is equal to preset data amount；In shape During state b, business A produces data burst and increases, and business B produces data burst and reduces, and the data burst increment of A is more than B's Data burst decrement, at this time, the buffer data size of A business are more than preset data amount size, and the buffer data size of B business is less than Preset data amount size, since the buffer data size size of A business and the absolute value of difference of preset data amount size are more than B business Buffer data size size and preset data amount size difference absolute value, so A business is subject in overall scheduling, using first Scheduling rates.Through that after a period of time, can reach c states, at this time, the buffer data size of A business is more than preset data amount size, The buffer data size of B business is less than preset data amount size, due to buffer data size size and the preset data amount size of B business Difference absolute value be more than A business buffer data size size and preset data amount size difference absolute value, so overall tune B business of being subject to is spent, using the second scheduling rates；The buffer data size of final two-way business is oscillated about in preset data amount, Arrival state d.

In specific implementation process, if had in two-way business datum all the way, business datum damages, according only to lossless The buffer status of business datum determines scheduling rates all the way.
