Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Below part term that the embodiment in the embodiment is occurred describe:
" agreement " is meant communication protocol.For example, " agreement " can be signaling protocol (for example detection protocol and Routing Protocol) or bearer service agreement (for example IPv6 agreement or ether agreement).Wherein, detection protocol can be bidirectional transmission detecting protocol (Bidirectional Forwarding Detection, BFD) or operation management maintenance protocol (operation, administration and maintenance, OAM); Routing Protocol can be Border Gateway Protocol (Border Gateway Protocol, BGP) or tag distribution protocol (Label Distribution Protocol, LDP).
" protocol data " is made of " protocol data elementary cell ", for example for the bearer service agreement, can be the IPv4 agreement, perhaps the ether agreement; Accordingly, protocol data is the IPv4 data flow, perhaps the ether data flow; The protocol data elementary cell is IPv4 grouping, perhaps Ether frame.
Embodiment one:
The embodiment of the invention provides a kind of data transmission method for uplink, specifically referring to Fig. 1.Fig. 1 is the data transmission method for uplink flow chart that the embodiment of the invention provides.Data transmission method for uplink comprises:
101: generate first protocol data.During specific implementation, protocol type can have multiple, and generating mode also can have multiple.Present embodiment does not limit protocol type and generating mode.
During specific implementation described " generation ", can be that the transmit status machine directly generates first protocol data, after perhaps first protocol layer (service layer) is received the data that upper strata (client layer) provides, it is packaged into first protocol data.
102: be the first protocol data elementary cell configuration identifier.Be that the first protocol data elementary cell configuration identifier can be that the first protocol data elementary cell is converted into the second protocol data elementary cell.For example, first protocol data is the IPv4 data flow, and second protocol data is the IPv4 data flow, is designated " 1 " and is used to show that the IPv4 grouping is converted into IPv6 divides into groups, and is designated " 0 " and is not used to show that the IPv4 grouping not being converted into IPv6 divides into groups.
When the specific implementation of the embodiment of the invention, the user can determine whether any one the first protocol data elementary cell in first protocol data is converted into the second protocol data elementary cell as required.In addition, the user can user-defined identification, even with " empty sign " expression the first protocol data elementary cell is converted into the second protocol data elementary cell.
About the specific implementation of " configuration identifier " this process, multiple mode can be arranged.For example, the first protocol data elementary cell is the IPv4 grouping, and the second protocol data elementary cell is the IPv6 grouping.IPv4 grouping is converted in the process of IPv6 grouping (seeing also embodiment seven), needs to transmit some information.These " information " can comprise the sign in 102.

Further, pre-defined rule is: the destination of first kind elementary cell is first destination; The destination of the second type elementary cell is second destination.For example, pre-defined rule can be the destination of IPv4 grouping, and the destination of the IPv4 that has grouping is user 1, and the destination of the IPv4 grouping that has is user 2, and user 1 address is different from user 2 address.Therefore, after the data transmission method for uplink processing through the embodiment of the invention, what user 1 received is the IPv6 grouping, and what user 2 received is the IPv4 grouping.Certainly, first destination also can be identical address with second destination.
Further, first protocol data and second protocol data are respectively IPv4 data flow and IPv6 data flow, perhaps,
First protocol data and second protocol data are respectively IPv6 data flow and IPv4 data flow, perhaps,
First protocol data and second protocol data are respectively IPv4 data flow and ether data flow.
