For the problem that can not realize transfer resource batch control and management in prior art, the embodiment of the present invention provides a kind of data stream transmitting control method, and its flow process as shown in Figure 1, comprises the steps:
Step S101: the transmission control and management message that obtaining communication end points sends over.
Communication end point is when needing the bulk transfer of carrying out data flow to control, and can generate transmitting managing and controlling message, the bulk management for data flow controls.Wherein transmission control and management message can comprise at least one in following message: data flow creates message, priority dynamic conditioning message and transmission state control message.Also can be other the message that can realize data flow bulk management.
Data flow establishment message creates for the batch of data flow; Priority dynamic conditioning message is used for the adjustment in batches of data stream priority; Transmission state control message controls for the batch of data stream transmitting state, such as: suspend transmission, recover transmission, stop the operations such as transmission, the control of delivery flow rate and termination.
The transmission control and management message of what the communication end point received communication end points of Correspondent Node sent carry data frame type, stream identification information that bulk management indication information is relevant with bulk management, being identified by data frame type is that data flow creates message, priority dynamic conditioning message, or transmission state control message, carries out corresponding bookkeeping so that follow-up.
Step S102: parse the data frame type carried in transmission control and management message, the stream identification information that bulk management indication information is relevant with bulk management.
Bulk management indication information is carried by an idle bit position selected in transmission control and management message frame head or frame, can from corresponding location resolution out during parsing.This bulk management indication information is mainly used in indicating whether to be batch operation, and the bit that such as selection one is idle is defined as " Group flag ", when this bit is 0, represents the individual operations for named data stream; When this bit is 1, represent the batch operation of the data flow of specifying for certain data flow group or some.
The stream identification information that bulk management is relevant can by carrying in transmission control and management message frame head traffic identifier field or frame traffic identifier field, concrete, when transmit control and management message be data flow create message time, the stream identification information that bulk management is correlated with is the mark of the data flow group of the association of carrying in frame head traffic identifier field or frame traffic identifier field.When transmit control and management message be priority dynamic conditioning message or transmission state control message time, the stream identification information that bulk management is correlated with is the mark of stream identification or the data flow group of carrying in frame head traffic identifier field or frame traffic identifier field.
Preferably, last stream identification whether stream identification that adjustment in batches designator identifies batch operation is further batch process can also be added in the reservation position before frame head traffic identifier field or frame traffic identifier field.Such as, can by judging that the adjustment in batches designator value in the reservation position before frame head traffic identifier field or frame traffic identifier field is 1 or 0, determine that whether stream identification that traffic identifier field carries is last stream identification of batch process.
Step S103: according to data frame type, determines the bookkeeping needing to carry out data flow to be managed.
The communication end point of Correspondent Node is that data flow creates message according to the data frame type parsed, priority dynamic conditioning message, or transmission state control message, determines that the bookkeeping that will carry out is the bookkeepings such as data flow establishment, priority dynamic conditioning, or transmission state control.
Step S104: the stream identification information that bulk management indication information is relevant with bulk management, performs the bookkeeping determined to corresponding data flow.
The communication end point of Correspondent Node is determined to need to perform the operation of data flow adjustment in batches according to the bulk management indication information parsed, and determine which the data flow needing bulk management to control has according to the stream identification information that the bulk management parsed is correlated with, thus realize controlling data flow bulk management.
In said method, two communication end points as Correspondent Node can send mutually priority dynamic conditioning message.Wherein, the communication end point as data stream reception end obtains the transmission control and management message sended over as the communication end point of data flow end, realizes data flow end designation data stream receiving terminal and carries out bulk management to data accepted stream; Or obtaining as the communication end point of data flow end the transmission control and management message sended over as the communication end point of data stream reception end, data stream reception end designation data stream transmitting terminal carries out bulk management to data flow to be sent.
Embodiment one
The data stream transmitting control method that the embodiment of the present invention one provides, be created as example with data flow batch, its flow process as shown in Figure 2, comprises the steps:
Step S201: communication end point configuration data stream creates message.
The data flow of configuration creates the frame head form of message as shown in Figure 3, and each frame comprises: the frame head of 8 bytes and length are at the frame of 0 to 65535 bytes.Wherein frame head comprises following field:
Length (16 bit)-frame byte length.(not comprising the frame head of 8 bytes)
The type of type (8 bit)-identification frames.
The Boolean flag marking (Flags, 8 bits)-associate with frame type.
Retain position (R, 1 bit).
Stream identification (Stream id, 31 bits)-value represents when being 0 that this frame acts on the data flow of whole connection and non-individual.
When configuration batch creates the data flow establishment message of data flow, expand HEADERS frame, generate data flow and create message, wherein, the data frame type field in HEADERS frame need not be expanded, and can continue to use former definition.
HEADERS frame frame head is expanded, be defined as groupflag at selection idle flags bit and carry bulk management indication information, for marking bookkeeping corresponding to this HEADERS frame for only to create data flow, or when creating data flow, the data flow that the data flow of establishment and other have created is associated.
HEADERS frame frame head or frame being expanded, carries the stream identification information that bulk management is relevant, for when creating data flow, carrying out the appointment of data flow group relation and cross-correlation etc.The group flag field of above-mentioned frame head definition marked the new data flow created, and whether to have created data flow group to certain relevant, and group flag field value is 0, identifies this data flow and other have created data flow and do not have incidence relation; Value is 1, identifies this data flow and belongs to certain data flow group.Then expand at frame head or frame head, mark the establishment data flow be associated with establishment data flow, optionally, stream-id field can be utilized to realize expansion.Such as, be the situation of 1 for group flag field value, in first 4 byte of frame, the signless integer of expansion interpolation reservation bit and 31 bits, is used to specify belonged to data flow group id.This id should correspond to one be in open (open), semi-closed (long-range) (half-closed(remote)) or the establishment data flow of reserved (reserved) state, otherwise receive the side that this data flow creates message and can report an error (PROTOCOL_ERROR); Be such as 0 for group flag field value again, then stream-id field identification is for the id of individual data streams, illustrates that the data flow created does not need and other data stream association.
For example, create data flow AAAA before, present HEADERS frame creates new data stream B BBB, wish to set up group relation with data flow AAAA, then, the extended field content that the frame of the HEADERS frame after expansion or frame head comprise is: XAAAA+X priority+... identifying is BBBB and AAAA association, belongs to the same data flow group by AAAA mark.
Step S202: communication end point sends data flow and creates message to the communication end point of Correspondent Node.
Wherein, communication end point can be data flow end also can be data stream reception end; Data stream reception end is generally the terminal equipment of user, and data flow end is generally the server end providing user data, and vice versa.
Step S203: the data flow that the communication end point received communication end points of Correspondent Node sends creates message.
Step S204: parse the data flow got and create the data frame type carried in message, the stream identification information that bulk management indication information is relevant with bulk management.
From data frame type field, parsing data frame type creating message for creating data flow, from the group flag of frame head expansion, parse 1 this bulk management indication information, parse from the Stream id field of frame or frame head XAAAA+X priority+...Can determine it is create the new data stream associated with data flow AAAA.
Step S205: according to the data frame type parsed, stream identification information that bulk management indication information is relevant with bulk management, performs the data flow creation operation of group associations.
Create the new data stream BBBB associated with data flow AAAA, both belong to a group.

For WINDOW_UPDATE frame, WINDOW_UPDATE frame frame head is expanded, be defined as group flag in selection idle bit position and carry bulk management indication information, be individual operations for certain specific data stream for marking bookkeeping corresponding to this WINDOW_UPDATE frame, or for the batch operation of certain data flow group, namely mark the sphere of action of this operation.When group flag value is 0, identify the individual operations that the operation of this WINDOW_UPDATE frame is the named data stream for the stream-id field identification in frame head or frame.When group flag value is 1, identify the batch operation that the operation of this WINDOW_UPDATE frame is certain the data flow group for the stream-id field identification in frame head or frame.
WINDOW_UPDATE frame frame head or frame are expanded, carries the stream identification information that bulk management is relevant, for when data stream transmitting state controls, specify all to the bookkeeping which data flow is correlated with.
The group flag field of above-mentioned frame head definition marked whether batch operation, and group flag field value is 0, identifies named data stream individual operations; Value is 1, identifies the batch operation to multiple data flow.Then expand at frame head or frame head, the data flow in mark sphere of action, optionally, stream-id field can be utilized to realize expansion.Such as, in first 4 byte of frame, the signless integer of expansion interpolation reservation bit and 31 bits, is used to specify the stream coverage involved by batch operation.The stream identification information that wherein bulk management is relevant can be identified by following two kinds of situations:
Mode one: when batch operation is for specific data flow group, designated group ID in stream-id field, its scope comprises all data flow of specifying with this data stream association.
Mode two: when batch operation is for multiple data flow, carry the stream identification of batch process in stream-id field, the data flow involved by Explicit designation batch process.
