Description
Technical field
The present invention relates to communication field, relate in particular to a kind of data processing method, transmitting apparatus, receiving equipment and communication system.
Background technology
In communication system, existing LTE (LongTermEvolution, Long Term Evolution) terminal equipment and PC (PersonalComputer) machine/main frame (serve, server) carry out TCP/IP (TransmissionControlProtocol/InternetProtocol, transmission control protocol/Internet Interconnection agreement) when transfer of data, general by USB (UniversalSerialBUS, USB) connect, adopt USB-NCM communication protocol, mainly utilize USB-NCM efficient data to transmit to mate the strict demand of LTE to large data throughout and sequential.
USB-NCM protocol specialized is the network adapter that various use USB connect, and has defined the model (being generally 802.3 Ethernets) of transmission IEEE.802 family network data.USB-NCM agreement is incorporated in multiple Ethernet data bags in single NCM (networkconfigurationmanager, network configuration management) transmission block (NTB), utilizes the disposable transmission of USB-Transfer to improve efficiency of transmission.Its support 16bit(once transmit 64KB) and 32bit(once transmit 4GB) transformat.PC utilizes Ethernet bag to carry TCP/IP data, the 16bit of NTP and the packet format of 32bit are as depicted in figs. 1 and 2, from Fig. 1 and Fig. 2, can find out, by obtaining the NDP(NCMDatagramPoint indicating in NTB build) chained list, can retrieve start address and the length of each Ethernet data bag in NTB, and then access each Ethernet data bag.
In the time carrying out TCP/IP transmission, terminal equipment need to wrap IP in each Ethernet bag from NTB and extract, then sends to high level or protocol layer, and this just need to resolve Ethernet bag.
General ether packet format has two kinds to be respectively 802.3 standards and EthernetII standard at present, as shown in Figure 3,802.3 standard ethernet packet formats are by the destination address of 6 bytes, 6 byte source addresses, 2 byte length fields, Deta bearer are (when packet length less than 64 byte, need extra filling), CRC(CyclicRedundancyCheck, cyclic redundancy check (CRC) code) check field forms.Wherein, for the different agreement data of district office's carrying, in Deta bearer beginning, be generally the LLC-SNAP field of 8 bytes, the protocol data that LLC-SNAP field identification is different, such as IP message, ARP message etc.
EthernetII (the Ethernet second layer) standard ethernet packet format is made up of 6 byte destination addresses, 6 byte source addresses, 2 byte type fields, Deta bearer (when packet length less than 64 byte, need to additionally fill), CRC check field.Wherein, by the different value of type of service field, identify different protocol datas, represent ARP message such as 0x0800 represents IP message, 0x0806.
In sum, as retrieved the IP message in USB-NCMNTB, just need to monitor one by one the type field in each Ethernet bag, for example: if adopt 802.3 forms, need the LLC-SNAP field of verification 8 bytes, if adopt EthernetII form, need the type field of verification 2 bytes, as shown in Figure 4.Visible terminal equipment wraps type checking at every turn, all must cross over the data area of at least 64 bytes, and the data that read 2/8 byte compare.Cause program numerous and diverse, treating capacity is larger.
