In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
System provided by the invention can be as shown in Figure 3, and this system mainly comprises: the data processing equipment 301 that is connected with headend, the common DTU (Data Transfer unit) 302 that connects of each terminal equipment and the data processing equipment 303 that is connected with DTU (Data Transfer unit) 302.
In this system, each terminal equipment in the multi-terminal network is connected with same DTU (Data Transfer unit) 302, each internal interface of DTU (Data Transfer unit) 302 connects a terminal equipment, and each internal interface possesses different MAC Address, outside ip address and implicit IP address.
When carrying out the uplink throughput test, data processing equipment 303 sends n bar data flow to DTU (Data Transfer unit) 302, and wherein n is the number of terminal equipment.The purpose IP address of each data flow and target MAC (Media Access Control) address are respectively the IP address and the MAC Address of data processing equipment 301, source MAC is the MAC Address of data processing equipment 303, and source IP address is respectively the implicit IP address of DTU (Data Transfer unit) 302 each internal interface.That is to say the source IP address difference of the n bar data flow that data processing equipment 303 sends.
DTU (Data Transfer unit) 302 is mated the n bar data flow that the receives implicit IP address according to source IP address and each internal interface, and the source IP address of each data flow and source MAC be revised as the outside ip address and the MAC Address of the internal interface of this data flow coupling respectively, amended data flow is sent to each terminal equipment by each internal interface.
Each data flow is sent to data processing equipment 301 through terminal equipment and headend.
After data processing equipment 301 receives each data flow, the flow that receives data flow is added up, utilized statistics and data transmission period to determine uplink throughput.
In addition, need to prove, data processing equipment 303 before sending data n bar data flow, can according to based on transport layer protocol this data flow is carried out protocol encapsulation, for example, carry out transmission control protocol (TCP) encapsulation or User Datagram Protoco (UDP) (UDP) encapsulation.Correspondingly, after data processing equipment 301 receives each data flow, at first the data flow that receives is carried out decapsulation, for example, separate the TCP encapsulation or separate the UDP encapsulation.
When carrying out the downlink throughput capacity test, data processing equipment 301 sends n bar data flow to headend, wherein, the source MAC of each data flow and source IP address are respectively the MAC Address and the IP address of data processing equipment 301, and purpose IP address and target MAC (Media Access Control) address are respectively the outside ip address and the MAC Address of DTU (Data Transfer unit) 302 each internal interface.
