Hereinafter, based on control system with time delay 100 shown in FIG. 1, the embodiment of the present invention provides a kind of delay control method, As shown in figure 3, this method includes：
101st, control device determines the type of service of object message.
Wherein, object message needs to reach receiving terminal by a transmission networks of N (N >=1) successively from transmitting terminal.It for example, should Object message is since transmitting terminal, it is necessary to be passed by the RAN of the RAN transmission networks of transmitting terminal, EPC transmission networks and receiving terminal Defeated network reaches receiving terminal.
Illustratively, control device can continue to use the means of identification of existing message traffic type, for example, passing through DPI (Deep Packet Inspection, deep message detection), obtain object message VPN (Virtual Private Network, it is empty Intend dedicated network) it identifies or according to the hands such as classification of configuration template of virtual machine when creating virtual machine for the object message Section, to determine the type of service of above-mentioned object message.
For example, the type of service of object message can specifically include IP packet or non-IP packet, in another example, object message Type of service can specifically include video traffic message, speech business message etc., and the embodiment of the present invention is not restricted this.
102nd, control device assigns each transmission network in N number of transmission network according to above-mentioned type of service for object message The time delay index of network.
Each type of service and N number of transmission network can be stored in a kind of possible realization method, in control device Correspondence between time delay index is type of service 1 and the time delay index of each transmission network as shown in table 1 illustratively Between correspondence and type of service 2 and the time delay index of each transmission network between correspondence.So, when true Set the goal message type of service be type of service 1 when, according to the correspondence shown in table 1 object message can be determined in N The time delay index of each transmission network in a transmission network.

Transmission network 1 Transmission network 2 …… Transmission network N
Type of service 1 10ms 8ms-20ms …… 20ms(±3ms)
Type of service 2 8ms 12ms-18ms …… 20ms(±2ms)
Wherein, the time delay index of arbitrary transmission network can be represented with specific numerical value, for example, in table 1, in transmission network The time delay index of the message of transmission services Class1 is 10ms in network 1；Alternatively, the time delay index of above-mentioned transmission network can also be used One interval range represents that, for example, in table 1, the time delay index of the message of transmission services Class1 exists in transmission network 2 Within 8ms-20ms, at this point, control device can select a value as time delay index in the interval range of 8ms-20ms；Again Alternatively, the time delay index of above-mentioned transmission network can also be represented with a specific numerical value and its error range, for example, in table 1 In, in transmission network N the time delay index of the message of transmission services Class1 be 20ms, value error within (± 3ms), So, control device can select a value as time delay index in the interval range of 17ms-23ms.
Further, when the time delay index of transmission network is an interval range, which can be according to this Before message transmission procedure, the history time delay value that the message of the type of service is spent when being transmitted in different transmission networks determines 's.For example, in nearest one day, the message of type of service 1 transmits the minimum history time delay value spent in transmission network 2 and is 8ms, maximum history time delay value be 20ms, hence, it can be determined that in transmission network 2 message of transmission services Class1 time delay Index is in the interval range of 8ms-20ms.
Each type of service can also be stored in alternatively possible realization method, in control device in different transmission networks At least one processing procedure performed is needed in network during transmission.Illustratively, as shown in table 2, for type of service 1 message every The message of at least one processing procedure and type of service 2 performed is needed in a transmission network during transmission in each transmission network At least one processing procedure performed is needed in network during transmission.
Table 2
Transmission network 1 Transmission network 2 …… Transmission network N
Type of service 1 3 processing procedures 2 processing procedures …… 6 processing procedures
Type of service 2 3 processing procedures 4 processing procedures …… 3 processing procedures
So, when assigning the time delay index of each transmission network for above-mentioned object message, with the first transmission network (first Transmission network is one in N number of transmission network) exemplified by, control device can determine first according to the type of service of object message The M processing procedure that transmission equipment transmission objectives message needs perform in the first transmission network, M >=1；And then determine this M The delay in phases index of each processing procedure in processing procedure, then, the sum of delay in phases index of this M processing procedure is The time delay index of first transmission network；Similar, it can be determined in N number of transmission network each by cycling the execution above method The time delay index of transmission network.
By taking SDN transmission networks as an example, the transmission equipment in SDN transmission networks can perform ACL in transmitting message (Access Control List, accesses control list) exports back-pressure, queue caching, CAR (Committed Access Rate, committed access rate) configuration, congestion queue configuration, redirection, drop policy configuration, broadcast or multicast processing, again 10 processing procedures such as group is wrapped and NAT (Network Address Translation, network address translation) is passed through perform Each processing procedure the time it takes (i.e. delay in phases index) is usually fixed, still, the message of each type of service It is usually a subset in this 10 processing procedures to need the processing procedure performed, as shown in figure 4, for type of service 1 Message at least needs to perform ACL, outlet back-pressure, re-group package and NAT passes through this 4 processing procedures, can complete SDN Transmission network is to the transmission process of the message, then, time delay index be this 4 processing procedures delay in phases index it With i.e. T0+T1+T8+T9；And for the message of type of service 2, execution ACL and NAT is at least needed to pass through this 2 and is treated Journey can complete transmission process of the SDN transmission networks to the message, then, time delay index is this 2 processing procedures The sum of delay in phases index, i.e. T0+T9.
So, control device can filter out a part and transmit the target report according to the type of service of object message Unnecessary processing procedure when literary, so as to reduce the time delay for transmitting the object message, also, can also be with each processing procedure Delay in phases index is granularity, and time delay of the Precise control object message in the transmission link of each transmission network distributes feelings Condition.
It should be noted that above-mentioned only illustrate by taking 10 processing procedures in SDN transmission networks as an example, it can With understanding, the processing procedure that transmission equipment performs in different transmission networks is not quite similar, but can apply above-mentioned side Method determines the M that transmission equipment transmission objectives message needs perform in each transmission network according to the type of service of object message A processing procedure.
103a, control device are assessed to the first transmission control unit (TCU) transmission delay and ordered, and are carried in time delay assessment order The time delay index of first transmission network.
103b, control device are assessed to the second transmission control unit (TCU) transmission delay and ordered, and are carried in time delay assessment order The time delay index of second transmission network.
……
103n, control device are assessed to N transmission control unit (TCU)s transmission delay and ordered, and the is carried in time delay assessment order The time delay index of N transmission networks.
After the time delay index of each transmission network is determined, in step 103 (including step 103a-103n), control " negotiation " mechanism may be employed in control equipment, respectively the transmission control unit (TCU) transmission delay assessment order into each transmission network, In, the time delay index of transmission network where carrying it in the time delay assessment order that each transmission control unit (TCU) receives.Namely It says, control device can be assessed by transmission delay and ordered, and can the transmission network where " inquiry " each transmission control unit (TCU) expire The time delay index assigned in sufficient step 102.
Subsequently, above-mentioned " negotiation " mechanism will by taking the first transmission control unit (TCU) in the first transmission network as an example, be elaborated Detailed process.
104th, after the first transmission control unit (TCU) receives above-mentioned time delay assessment order, determine to transmit mesh in the first transmission network Whether the time delay of mark message meets the time delay index of the first transmission network.
105a, the first transmission control unit (TCU) send assessment response to control device, which is included in the first transmission network The time delay that transmission objectives message needs in network.
It at step 104, can be with after the first transmission control unit (TCU) in the first transmission network receives time delay assessment order It further determines that：Whether the time delay of transmission objectives message meets the first transmission assigned in step 102 in the first transmission network The time delay index of network.
Certainly, if having determined that transmission equipment transmission objectives message needs in the first transmission network in a step 102 The M processing procedure and the delay in phases index of each processing procedure to be performed, then, specifically may be used in above-mentioned time delay assessment order To include the delay in phases index of each processing procedure in the mark of this M processing procedure and this M processing procedure.
It should be noted that the priority that the embodiment of the present invention is not limited between step 104 and step 103b-103n performs Sequentially, step can be performed after the first transmission control unit (TCU) receives the time delay assessment order that control device is sent in step 103a Rapid 104.
Specifically, the first transmission control unit (TCU) can determine to transmit the transmission of the object message in the first transmission network first Equipment, for example, the first transmission equipment, and then, it is treated that time delay can be assessed M carried in order by the first transmission control unit (TCU) The delay in phases index of the mark of journey and each processing procedure is sent to the first transmission equipment, by the first transmission equipment according to work as Preceding loading condition assesses whether that corresponding processing procedure can be completed in each delay in phases index.
Illustratively, by taking SDN transmission networks as an example, the time delay assessment that the SDN controllers in SDN transmission networks receive is ordered Order includes the mark that ACL and NAT passes through this 2 processing procedures, wherein, the delay in phases index of ACL is 1ms, what NAT was passed through Delay in phases index is 1ms.So, above-mentioned time delay can be assessed order by SDN controllers can be transmitted to router 1, and then, Router 1 according to the number of current message to be treated, be estimated as respectively above-mentioned object message perform ACL and NAT pass through this 2 The time delay of a processing procedure determines whether that ACL can be completed in 1ms, and completes NAT in 1ms and pass through.If can be with Corresponding processing procedure is completed in each delay in phases index, then router 1 can send to the first transmission control unit (TCU) and meet The assessment response of the time delay index of above-mentioned first transmission network；If place accordingly can not be completed in each delay in phases index Reason process, then router 1 can be sent to the first transmission control unit (TCU) be unsatisfactory for the time delay index of above-mentioned first transmission network and comment Estimate response.
No matter the time delay index of above-mentioned first transmission network can be met, and may each comprise assessment in above-mentioned assessment response obtains The transmission objectives message in the first transmission network need time delay.
For example, perform the time delay of ACL when router 1 is estimated as above-mentioned object message as 0.8ms, perform that NAT passes through when Prolong for 1ms when, i.e., router 1 can complete corresponding processing procedure in each delay in phases index；Alternatively, when router 1 It is estimated as above-mentioned object message and performs the time delay of ACL as 0.8ms, when the time delay that execution NAT is passed through is 1.2ms, i.e., router 1 can To complete ACL in the delay in phases index of 1ms, but NAT can not be completed in the delay in phases index of 1ms and passed through.At this point, routing Device 1 by the time delay of the execution ACL estimated and can perform time delay (i.e. in the first transmission network transmission objectives that NAT pass through Message need time delay) carry the first transmission control unit (TCU) is sent in assessment response, subsequently will be upper by the first transmission control unit (TCU) It states assessment response and is sent to control device.
Similar, the transmission control unit (TCU) in other transmission networks assesses order in the time delay for receiving control device transmission Afterwards, it by the method in above-mentioned steps 104, can also determine whether the time delay of the transmission objectives message in this transmission network meets The time delay index of this transmission network, and then, assessment response is sent to control device, that is, performs following step 105b-105n：
105b, the second transmission control unit (TCU) send assessment response to control device.
……
105n, N transmission control unit (TCU)s send assessment response to control device.
Similar, the embodiment of the present invention does not limit the priority execution sequence between step 104 and step 105b-105n.
106th, after control device receives the assessment response of the first transmission control unit (TCU) transmission, if being passed in the first transmission network The time delay of defeated object message is more than the time delay index of the first transmission network, then control device is to the time delay index of the first transmission network It is modified.
If the time delay of transmission objectives message is more than the time delay index of the first transmission network in the first transmission network, for example, When the time delay (1.2ms) that above-mentioned execution NAT is passed through is more than delay in phases index (1ms) that NAT is passed through, control device can be to the The time delay index of one transmission network is modified.
In a kind of possible realization method, if the second transmission network (the second transmission network that control device receives For any one in above-mentioned N number of transmission network in addition to the first transmission network) in the second transmission control unit (TCU) report some is treated The time delay of journey also has the surplus of 0.2ms (or more than 0.2ms), then control device can be passed through NAT in the first transmission network On the basis of delay in phases index (1ms), remaining 0.2ms in the second transmission network is dispatched to the first transmission network, and then, Controller can repeat above-mentioned steps 104-105, until the time delay of transmission objectives message meets the in the first transmission network The time delay index of one transmission network.
Certainly, in the above-described embodiments, since router 1 performs the time delay of ACL as 0.8ms, the delay in phases less than ACL Remaining 0.2ms when performing ACL can also be dispatched to the delay in phases that NAT is passed through and referred to by index (1ms), therefore, control device Mark, i.e. the delay in phases index that NAT is passed through are 1ms+0.2ms=1.2ms.
In alternatively possible realization method, it can not also be included in the assessment response that the first transmission control unit (TCU) reports The time delay that transmission objectives message needs in first transmission network.So, in step 106, once being passed in the first transmission network The time delay of defeated object message is more than the time delay index of the first transmission network, and control device can directly be sent out to the first transmission control unit (TCU) It send and replaces transmission equipment order, and then new transmission equipment is reselected by the first transmission control unit (TCU), for example, router 2, lays equal stress on Can new assessment router 2 meet the time delay index of the first transmission network, until above-mentioned first transmission network can be met by finding Time delay index transmission equipment.At this point, the embodiment of the present invention does not limit the elder generation between step 106 and step 105b-105n Execution sequence afterwards.
Further it will be understood that between above-mentioned steps 106 and step 103b-103n also and there is no priority execution Sequentially, that is to say, that for different transmission networks, between the transmission control unit (TCU) in control device and some transmission network The process of the time delay index of " negotiation " transmission network can be independent from each other.
Certainly, if in the assessment response that the first transmission control unit (TCU) reports, the transmission objectives message in the first transmission network The time delay needed is much larger than the time delay index of the first transmission network, i.e.,：Transmission objectives message needs in the first transmission network The difference of time delay and the time delay index of the first transmission network is more than predetermined threshold value, for example, the time delay index of the first transmission network is 10ms, predetermined threshold value 5ms, and in the assessment response that the first transmission control unit (TCU) reports, the transmission objectives in the first transmission network The time delay that message needs is 20ms (20ms-10ms ＞ 5ms), then, control device is without referring to the time delay of the first transmission network Mark is modified, but can directly be sent to the first transmission control unit (TCU) and be replaced transmission equipment order, by the first transmission control unit (TCU) New transmission equipment is reselected, until finding the transmission equipment that can meet above-mentioned time delay index.
If the time delay index of the first transmission network is still less than the transmission objectives report in the first transmission network after the 107th, correcting Text time delay, then control device to the first transmission control unit (TCU) send replace transmission equipment order.
Specifically, if the time delay index of first transmission network is still less than in the first transmission network after being corrected in step 106 The time delay of interior transmission objectives message, for example, after remaining time delay index is all dispatched to the first transmission network in all transmission networks, The time delay index of first transmission network then illustrates currently to exist still less than the time delay of the transmission objectives message in the first transmission network The transmission equipment selected in first transmission network can not meet above-mentioned time delay index, then, control device can be to the first transmission Controller, which is sent, replaces transmission equipment order, and new transmission equipment is reselected by the first transmission control unit (TCU), can be with until finding Meet the transmission equipment of above-mentioned time delay index.
So far, control device can pass through the first transmission control unit (TCU) " association in above-described embodiment, with the first transmission network Business " obtains the time delay index of the first transmission network to match with the time delay of actual transmissions object message.Similar, other N-1 The time delay index of a transmission network can carry out " negotiation " according to the method described above, obtain each passing in entire N number of transmission network The time delay index of defeated network.
Subsequently, if the time delay of transmission objectives message is satisfied by the time delay index of the transmission network in each transmission network, Then control device sends message transmissions order to N number of transmission control unit (TCU) respectively, that is, performs following step 108a-108n：
108a, control device send message transmissions order to the first transmission control unit (TCU).
108b, control device send message transmissions order to the second transmission control unit (TCU).
……
108n, control device send message transmissions order to N transmission control unit (TCU)s.
That is, working as the time delay index for each transmission network that final " negotiation " obtains, it is no more than in each transmission In network transmission objectives message when be delayed, control device can respectively to N number of transmission control unit (TCU) send message transmissions order, connect The transmission control unit (TCU) of the message transmissions order received, such as the first transmission control unit (TCU), can be according to the first finally definite transmission The time delay index transmission objectives message of network, in this way, in each transmission network during transmission objectives message, it can be according to respective Time delay index transmission objectives message, so as to improve the control accuracy of time delay in message transmission procedure, reduces actual transmissions report The time delay of text is unsatisfactory for happening for time delay index.
In above-mentioned steps 101-108, the relevant action of control device can be by the processing of the control device referred in Fig. 2 Software module of the device in memory performs.
Further, transmitting terminal and receiving terminal are normally based on OSI (Open System when handling message at present Interconnect, open system interconnection) reference model is to message progress business processing, for example, transcoding, coding transform (Transcoding, TC) etc., each message are required for carrying out business processing in operation layer when sending and receiving.
That is, as shown in figure 5, transmitting terminal when handling each message, is required to carry out physics respectively to the message Layer, link layer, articulamentum, protocol layer, transaction layer, expression layer and operation layer totally 7 layers of processing procedure, and then, by each transmission Transmission equipment in network is handled the message in physical layer, link layer and articulamentum, and most the message is forwarded to and connects at last Receiving end, then by receiving terminal the message is carried out respectively physical layer, link layer, articulamentum, protocol layer, transaction layer, expression layer and Operation layer totally 7 layers of processing procedure, finally parses the data in the message.
However, when protocol layer, transaction layer, expression layer and operation layer handle the message, it is necessary to pass through CPU (Central Processing Unit, central processing unit) it interrupts and carries out data-moving between Ethernet and CPU, and transmitting terminal and receiving terminal It needs respectively in each message of protocol layer, transaction layer, expression layer and operation layer processing, this undoubtedly extends message transmission procedure In time delay.

202nd, control device carries out joint layout to the first business processing scheme and the second business processing scheme, is combined Business processing scheme, the execution sequence of the first business processing scheme is in the second business processing scheme in the consolidated traffic processing scheme Before.
That is, in consolidated traffic processing scheme after joint layout, it should handle the first business of transmitting terminal first Processing scheme, and then the second business processing scheme of receiving terminal is handled, it can so ensure the logical correctness of the object message.
203rd, consolidated traffic processing scheme is sent to receiving terminal by control device, after receiving terminal receives object message, The consolidated traffic processing scheme is performed by receiving terminal.
After above-mentioned consolidated traffic processing scheme is sent to receiving terminal by control device, transmitting terminal can be triggered and send the target Message, but unlike the prior art, as shown in fig. 7, transmitting terminal need not perform the first business processing scheme to object message, I.e. transmitting terminal need not perform processing scheme more than articulamentum in OSI Reference Model, be interrupted so as to avoid transmitting terminal by CPU The process of data-moving is carried out between CPU in Ethernet, and after receiving terminal receives object message, it is uniformly held by receiving terminal Row consolidated traffic processing scheme, that is to say, that disposable transmitting terminal of completing is interrupted by CPU by receiving terminal and refers to mould in OSI The processing scheme of processing scheme and receiving terminal in OSI Reference Model more than articulamentum in type more than articulamentum, so as to subtract Ethernet is lacked to the time delay consumption that CUP interrupt processings message traffic is travelled frequently between CPU and is brought.
In above-mentioned steps 201-203, the relevant action of control device can be by the processing of the control device referred in Fig. 2 Software module of the device in memory performs.
