detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a schematic diagram of a network architecture of the present invention. As shown in FIG. 1 , the present invention is directed to a problem of setting a TCP network proxy between a UE and a server to improve the transmission rate of the network, and determining a TCP network proxy by adopting the technical solution of the present invention. The size of the receiving window makes the configuration of the TCP network proxy more reasonable, thereby increasing the transmission rate of the network.

The technical solutions of the present invention will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

2 is a schematic flowchart of Embodiment 1 of a TCP network proxy configuration method according to the present invention. As shown in FIG. 2, the method in this embodiment is as follows:

S201: Acquire a size of a receiving window of the UE.

The TCP network proxy can analyze the uplink data packet sent by the UE, for example, an ACK data packet, and according to the windows field in the TCP header field of the uplink data packet, the size of the receiving window of the UE can be obtained, wherein the format of the TCP header field is as shown in FIG. 3 . 3 is a schematic diagram of a format of a TCP header field according to the present invention; FIG. 4 is a schematic diagram of an example of a TCP header field according to the present invention, as shown in FIG. 4, according to a ratio of a window size and a window size. The window size scaling factor calculates the size of the receiving window of the UE, or obtains the size of the receiving window of the UE according to the calculated window size.

S202: Acquire a first delay and a second delay.

The first delay is a delay between the TCP network proxy and the UE, and the second delay is a delay between the TCP network proxy and the Internet server.

One of the feasible implementations of obtaining the first delay is as follows: by the TCP network generation And a time when the first data packet is sent to the UE, a time when the TCP network proxy receives the acknowledgement of the first data packet sent by the UE to the first data packet, and the UE sends the first data packet to the TCP network The agent sends the time for confirming the first data packet, and determines the first time delay; FIG. 5 is a schematic diagram of TCP transmission between the TCP network proxy and the UE according to the present invention; and FIG. 5, obtains the first according to Tx, Ty, and Tz. Delay, where Tx represents the time when the TCP network proxy sends the first data packet to the UE, Ty represents the time when the UE sends the first data packet to the TCP network proxy, and Tz indicates that the TCP network proxy receives the first data sent by the UE. The time at which the packet confirms the first packet. For the first time to calculate the first delay, the Tx needs to be recorded by the TCP network proxy, and the first delay calculated according to the clock of the TCP network proxy is (Tz-Tx)/2; because the TCP network proxy and the UE's clock are not synchronized. In case, the first delay calculated according to the clock of the UE is Tz-Ty. Therefore, it can be deduced that the clock difference between the TCP network proxy and the UE is T*=Tz-Ty-(Tz-Tx)/2; that is, according to the first calculation The clock difference T* between the TCP network proxy and the UE can be obtained. The first time delay is calculated in the subsequent data transmission process, and the first time delay of the TCP network agent can be known according to the obtained Tz-Ty-T*.

The first feasible implementation of obtaining the second delay is as follows:

Determining the second time delay by the time when the TCP network agent sends the second data packet to the Internet server, and the time when the TCP network agent receives the confirmation data packet of the second data packet by the Internet server; A schematic diagram of TCP transmission between the TCP network proxy and the Internet server is invented; in conjunction with FIG. 6, a second delay is obtained according to a=1/(Tm-Tn), where a represents a second delay, and Tn represents a TCP network proxy to the Internet. The time when the server sends the second data packet, and Tm indicates the time when the TCP network proxy receives the acknowledgement packet of the second data packet by the Internet server.

The second possible implementation of obtaining the second delay is as follows:

Determining, by the TCP network proxy, a time when the probe packet is sent to the Internet server, and a time when the TCP network proxy receives the acknowledgement packet of the probe packet by the Internet server, determining the second delay; The implementation is similar, and will not be described here.

The third possible implementation of obtaining the second delay is as follows:

Receiving, by the TCP network agent, the size of the data packet sent by the Internet server at the first moment, the second time, the TCP network proxy receiving the size of the data packet sent by the Internet server, and the first time to The TCP in the time period of the second moment The receiving window size of the network proxy determines the second delay. Specifically, the transmission rate O=(Pm−Pn)/(Tm−Tn) in the time period from the first time to the second time is first acquired; and the time period from the first time to the second time is assumed. The receiving window size of the TCP network proxy is Wp, and the second delay is a=Wp/O, where Pm indicates the size of the data packet sent by the TCP network proxy received by the Internet server at the second moment, Pn represents The TCP network agent receives the size of the data packet sent by the Internet server at the first moment, Tm represents the second time, Tn represents the first time, and the TCP is in the time period from the first time to the second time The receiving window size of the network proxy.

The execution order of S201 and S202 is not limited, and may be performed at the same time. S201 may be executed first, or S202 may be executed first, or S202 may be executed first, and then S201 is executed.

S203: Determine a size of a receiving window of the TCP network proxy according to the size of the receiving window, the first delay, and the second delay.

Specifically, it is determined that the size of the receiving window of the TCP network proxy is greater than or equal to a threshold, wherein the threshold is a product of a ratio of a ratio of the second delay to the first delay and a size of a receiving window of the UE.

Only when the size of the receiving window of the TCP network proxy is greater than or equal to the threshold, the performance of the transmission rate is optimized, and the multiple of the performance improvement is 1 + the second delay / the first delay.

In this embodiment, according to the principle that the ratio of the second delay to the first delay is the largest, the performance of the TCP network proxy is optimal, by acquiring the size of the receiving window of the user equipment UE, the TCP network proxy and the UE and the Internet server The first delay and the second delay are used to set the receiving window of the TCP network proxy. Thereby, the parameter setting of the TCP network proxy is made more reasonable, thereby improving the network transmission rate and improving the system throughput.

FIG. 7 is a schematic flowchart of Embodiment 2 of a TCP network proxy configuration method according to the present invention. The process of this embodiment is as follows:

S701: The first delay and the second delay when the TCP network proxy sets different positions between the UE and the Internet server.

When the relative position between the UE and the Internet server is different, the values of the first delay and the second delay acquired are different.

For the specific manner of obtaining the first delay and obtaining the second delay, refer to S202 in the embodiment shown in FIG. 2, and details are not described herein again.

S702: When determining that the ratio of the second delay to the first delay is the largest, the location of the TCP network proxy setting between the UE and the Internet server is an optimal configuration location of the TCP network proxy.

Because the transmission rate increase ratio of setting the TCP network proxy and not setting the TCP network proxy is 1+a/b, where a represents the second delay and b represents the first delay, therefore, in the second delay and the first time When the ratio of the delay is the largest, the location of the TCP network proxy between the UE and the Internet server is the optimal configuration location of the TCP network proxy. Generally, the optimal configuration location of the TCP network proxy is set in the eNB.

S703: Determine a product of a first time delay when the ratio of the second time delay and the first time delay is maximum, and a ratio of the ratio of the second time delay to the size of the receiving window of the UE, where the TCP network proxy is The size of the receiving window.

The size of the receiving window of the UE is obtained in S201 in the embodiment shown in FIG. 2, and details are not described herein again.

In this embodiment, when determining that the ratio of the first delay to the second delay is the largest, the location of the TCP network proxy between the UE and the Internet server is an optimal configuration location of the TCP network proxy, thereby enabling the TCP network proxy The location setting is more reasonable, and determining a product of a first delay when the ratio of the second delay to the first delay is maximum, and a ratio of the ratio of the second delay to the size of the receiving window of the UE is The size of the receiving window of the TCP network proxy optimizes the transmission rate, thereby increasing the network transmission rate and improving system throughput.

The present invention also provides a performance comparison between the transmission rate in the scenario where the TCP network proxy is not set and the setting of the network proxy scenario, wherein the transmission rate of the TCP network proxy is not set, that is, only one TCP is established between the UE and the Internet server. The transmission rate of the connection is less than the transmission rate of the TCP connection between the TCP network proxy and the UE in the case where the TCP network proxy is set, and is smaller than the transmission rate of the TCP connection between the TCP network proxy and the Internet server. Assume that the transmission rate between the UE and the Internet server without the TCP network proxy is R, the transmission rate between the TCP network proxy and the UE is P, and the transmission rate between the TCP network proxy and the Internet server is 0, which can be passed. R<min{O, P} represents the above relationship.

When O and P are equal, the TCP network proxy has the best effect on the transmission rate of the network. When the difference between O and P is larger, the effect of the TCP network proxy on the transmission rate of the network is worse.
