Description
Technical field
The invention belongs to the Networks and Communications technical field, relate to ether message multiplexing, Deplexing method and equipment.
Background technology
Along with of the development of network all-IPization with flattening, atm technology is eliminated, use point to point protocol (Point to Point Protocol, abbreviation PPP) the SDH/PDH network of technology is about to stop to build, ethernet technology obtains tremendous development at metropolitan area network even wide area network, and packet services transmission such as use Ethernet (Ethernet) carrying wireless speech are the trend of network development.
One prior art adopts frame tunneling (Frame Protocol is called for short FP) multiplexing (Multiplexing the is called for short Mux) technology on the wireless UDP layer to realize the transmission of packet services.The FPMux technology is (Radio Network Controller in the base station, be called for short RNC) and NodeB (Node of Base station, abbreviation NodeB) adopts the User Datagram Protoco (UDP) (multiplex technique of (User Datagram Protocol is called for short UDP) layer between.As shown in Figure 1, RNC or NodeB carry out FPMux when sending message, demultiplexing (FPDMux) when receiving guarantor's literary composition.For NodeB, NodeB links to each other with upstream RNC by Iub interface, being sent at NodeB needs to realize the FPMux operation on the data flow direction of RNC, the Differentiated Services mark that the multiplexing Channel number of being supported=NodeB supports (Diffserv Code Point is called for short DSCP) number.When receiving from downlink data that RNC comes, need to discern FPMux bag and normal non-Mux bag, need correctly demultiplexing reprocessing for the Mux bag.The encapsulation format of concrete FPMux is as shown in table 1:
Table 1 is the encapsulation format of FPMux
The agreement regulation, the unique definite multiplex channel of tlv triple (SIP, DIP, DSCP) also promptly has the data flow of identical SIP, DIP and DSCP value just can be multiplexed in the FP Mux frame.FP Mux is that a kind of UDP of being based upon upward carries out multiplexing technology to parcels such as voice, and the IP/UDP Header of message keeps fully, adds a Mux Header before each FP Payload, and UID generally is UDP DPORT.
There is following defective in this technology: owing to have IP head and UDP head simultaneously, therefore wasted some Internet resources; In addition because FPMux technology simultaneously compatible Ethernet and PPP because the SDH/PDH network of applying PPP no longer has development prospect, and need not support PPP for the ether bearer network, if therefore compatible PPP will waste some Internet resources.
Another prior art adopts intelligent time division multiplexing (Intelligent Time-DivisionMultiplexing is called for short ITDM) technology to realize the transmission of packet services.The ITDM technology is based on the TDM technology, can connects the multiple network technology of (containing IP network, PSTN/POTS network).The encapsulating structure schematic diagram of concrete ITDM field, as shown in Figure 2.Fig. 2 is described as follows: DMAC represents traditional target MAC (Media Access Control) address, 6 byte longs; SMAC represents the conventional source MAC Address, 6 byte longs; Ether Type represents that type of message is ITDM, 2 byte longs; DMAC, SMAC, Ether Type form MAC Header; PAD represents the filling field reserved, 6 byte longs; TAG represents to contain 2 byte message ID (16-bit Packet ID specifies JitterQueue on Destination Node) and 1 byte sequence number; PKT Type: show common ITDM message or ITDMCP control message; PAD TAG, PKT Type form ITDM Shim; Payload represents the message payload, and each Quad TDM Segment contains 4 TDM Segment and 4 Segment ID in the encapsulation of Payload, and length is respectively fixing 8 bytes and 2 bytes.When being packaged with 24 TDMSegment among the Payload, n=6 Quad TDM Segment can be arranged correspondingly.Can encapsulate 148 TDM Segment among the Payload at most, n=37 Quad TDM Segment correspondingly can be arranged at most.
There is following defective in this technology: only support the encapsulation of regular length message, and dumb; Even at the voice parcel, also need to take a plurality of TDM Segment (voice parcel typical length is 22 bytes); Do not support message priority; Adopt the microcode of TDM technology to realize complexity, the software complexity height may need specialized hardware to realize; Network Transmission needs the similar precision clock of E1/T1 to guarantee that cost is higher.
