The Transmission Control Protocol (TCP) is widely applied in communication Transmission, and has the advantages that high reliability and stability are realized through retransmission, a complex flow Control and congestion Control algorithm is arranged in the TCP to cope with possible faults and congestion in a communication link, the TCP is developed to the present day, various algorithm mechanisms are relatively mature, but problems which are difficult to overcome are still existed along with the rise of wireless communication, for example, a TCP receiving party cannot correctly identify the disorder and the loss of a message, when the disorder is relatively slight, such as adjacent packet sequence numbers and the like, the internal algorithm of the TCP can be corrected, when the disorder is relatively serious, the packet is considered to be lost, a quick retransmission mechanism can be triggered, the receiving party quickly retransmits ACK, the bandwidth is wasted when the message is retransmitted by a transmitting party, more seriously, the repeated ACK can cause the contraction of a transmitting window of the transmitting party, and the transmitting rate is greatly reduced.
With the development of the fifth Generation Mobile Communication technology (5G), a 5G base station is a loop in a Communication link and is a key node for connecting wireless and wired, wired Communication and wireless Communication have a great difference in fault performance, disorder is not common to wired Communication, packet loss is generally caused by node congestion, and wireless Communication has more disorder and packet loss due to channel interleaving coding and signal interference. Early TCP is designed mainly for wired transmission, and has fewer disorder and error codes, and once disorder/packet loss occurs, it is considered that network congestion occurs, and the sender will quickly reduce the sending window and reduce the sending rate, and then slowly increase the sending window according to ACK feedback, but for wireless, disorder and packet loss are common, and frequent reduction of the sending window greatly reduces the sending rate.
Therefore, a new transmission optimization method needs to be proposed for the wireless scenario, especially for TCP transmission in 5G base stations.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The transmission optimization method, system, electronic device and storage medium of the present invention are described below in conjunction with fig. 1-3.
Aiming at the problems that message disorder and packet loss are easy to occur when TCP wireless transmission is carried out in the existing 5G base station, at the moment, the sending window is shrunk and becomes small, so that the congestion and packet loss of a data network are caused, and air interface retransmission is caused. On the basis, the application provides an optimization method for TCP transmission of a 5G base station.
Fig. 1 is a schematic flow chart of a transmission optimization method provided by the present invention, as shown in fig. 1, including:
step 100: receiving a Transmission Control Protocol (TCP) message sent by a sending end;
step 200: in a TCP agent, sequencing the TCP messages to obtain ordered messages;
step 300: sending the ordered message to a receiving end, and caching the ordered message as a local message;
step 400: and receiving a TCP response message returned by the receiving end, optimizing the local message according to the current response number of the TCP response message, obtaining an optimized cache message, and sending the optimized cache message to the sending end.
The invention establishes a TCP agent in the 5G base station, and the TCP agent firstly sequences the TCP messages and then transmits the TCP messages to a transmission network according to the sequence; meanwhile, in order to deal with the burst-type network congestion, the TCP agent caches the sent message, and after receiving the ACK response of the network side, the corresponding message is removed for transmission.
Specifically, a proxy of an application layer TCP protocol is created on a 5G logic network element CU, a proxy example is established for each TCP link, TCP uplink data messages are sequenced according to SEQ numbers and cached locally, then the TCP uplink data messages are sent to a receiving party in sequence, when the ACK of the receiving party is received, a cache message smaller than the ACK number is removed, and if the message same as the ACK number exists locally, the message is retransmitted to the receiving party.
The invention effectively eliminates the phenomena of message retransmission and window reduction of a sending window caused by message disorder by adopting the TCP agent and the message cache in the TCP transmission of the 5G base station, and also solves the problem of air interface retransmission caused by congestion and packet loss of a data network.
On the basis of the above embodiment, in the TCP proxy, before the TCP packet is sequenced to obtain the ordered packet, the method further includes:
creating a plurality of said TCP proxies at a packet data convergence protocol layer PDCP or service data adaptation protocol layer SDAP of the central unit CU;
wherein each TCP proxy corresponds to a TCP link.
Specifically, before transmission, a TCP proxy module needs to be created in a Packet Data Convergence Protocol (PDCP) or Service Data Adaptation Protocol (SDAP) (where SDAP is an optional Protocol) Protocol layer of a Central Unit (CU) of a logical network element of the 5G base station, and a TCP proxy is created by the TCP proxy module, where each TCP proxy corresponds to one TCP link.
SDAP is a new sub-layer added to the 5G/NR user plane, and one of the functions of the layer is to map QoS flows with DRBs. Since the interface between the gNB and the 5GC in the 5G/NR is a newly added NG interface, the NG interface is based on QoS flow, and the air interface is based on DRB bearer of the user, or from PDCP to DRB bearer, an adaptation sublayer SDAP needs to be added in the 5G/NR to map QoS to DRB. The core network in LTE is an EPS bearer, which can directly correspond to a DRB bearer one by one without an adaptation process.
The 5G is generally reconstructed into two logical network elements, namely a CU and a Distributed Unit (DU), and may be deployed together or separately according to a scenario and a requirement. The CU mainly comprises a non-real-time wireless high-level protocol stack function and also supports partial core network function sinking and edge application service deployment; the DU mainly handles the physical layer functions and layer 2 functions required for real-time performance, and considering saving transmission resources between the RRUs and the DU, part of the physical layer functions may also be moved up to the RRUs for implementation.
The invention establishes a special channel for the TCP message by arranging the TCP agent in the centralized unit of the 5G base station, thereby facilitating the subsequent control of the TCP message.
On the basis of the above embodiment, in the TCP proxy, the ordering the TCP packets to obtain the ordered packets includes:
and sequencing the TCP messages in the TCP link corresponding to the TCP agent according to the serial number to obtain the ordered messages.
Specifically, after the TCP proxy is established, the TCP messages need to be sorted, where the received TCP messages are sorted according to SEQ numbers, where the SEQ numbers refer to Sequence numbers.
It should be noted that SEQ id No. is a sequence number, and as for the first sequence number of data to be sent, this sequence number is calculated by an algorithm to obtain an Initial Sequence Number (ISN) plus 1, and here, it is assumed that a sequence number is 1000 at a certain time, and a simple understanding is that the sender tells the receiver that "i send data starting from 1000"; the corresponding acknowledgement number ACK, where the acknowledgement number is the last successfully received data byte number plus 1, may also be understood as that the receiving end tells the sending end to want to receive the start number next time, and assuming that the acknowledgement number at a certain time is 1000, a simple understanding is that the receiving end tells the sending end that "i have received the 999 th sequence number, and i want to receive data next time from 1000.
The invention adopts the commonly used SEQ numbers in the TCP transmission control to sequence to obtain the ordered messages, and the response is carried out on the subsequent response messages according to the sending sequence, thereby being convenient for identifying and confirming the response information.
On the basis of the above embodiment, receiving a TCP response packet returned by the receiving end, optimizing the local packet according to the current response number of the TCP response packet, and obtaining an optimized cache packet includes:
acquiring response numbers of all messages in the local message;
extracting a first local message corresponding to the response number smaller than the current response number, and releasing the first local message to obtain a second local message;
and if the answer number is determined to have the same number as the current answer number, discarding the local message corresponding to the number from the second local message to obtain the optimized cache message.
Wherein, extracting the first local message whose answer number is smaller than the current answer number, releasing the first local message, and after obtaining the second local message, the method further comprises:
and if the answer number does not have the number which is the same as the current answer number, taking the second local message as the optimized cache message.
Specifically, the messages which are sorted are sent to the receiver in sequence, and the sent messages are cached locally. And for the received TCP ACK message, releasing a cache message smaller than the ACK number according to the ACK number, namely releasing the first local message to obtain a second local message, discarding the ACK message and retransmitting the cache message if the message same as the ACK number exists in the locally cached message, and otherwise, transmitting the ACK message to a sender.
The invention sorts TCP messages of a link in the base station, caches the TCP messages, clears the cache when receiving ACK of a receiver, and if repeated ACK is received and corresponding messages exist in the cache, the proxy retransmits the messages and discards the ACK, thereby eliminating the possibility of window shrinking of a sender.
When the TCP agent receives the ACK, if the cached message has the message with the same number as the ACK, the ACK is discarded, and the cached message is retransmitted, otherwise, the message is transmitted to the sender, so that the transmission bandwidth is saved, and the transmission efficiency is improved.
The transmission optimization system provided by the present invention is described below, and the transmission optimization system described below and the transmission optimization method described above may be referred to correspondingly.
