Description of the invention α): [Field of invention] A dynamic trigger length calculation method and system, more specifically,-it relates to a method for calculating the data length in a buffer through real-time calculation to determine the read from the buffer Dynamic trigger length calculation of reasonable values of data bytes: methods and systems. [Background of the Invention] Due to the rapid development of electronic information-related technologies, many powerful and affordable products have come out. Take computer communication equipment as an example, whether it is a large supercomputer, a server host, or even a personal computer and g-type. Computers, etc., have already become indispensable important channels and tools for people's information circulation. In addition, compared with the past, the hardware and software equipment of the current network communication system can be said to have considerable growth and improvement. Therefore, many large enterprises or companies have successively networked their organizations, whether it is The Internet, intranet, or extranet, of course, includes more than two or even three types of network communication systems. In addition to the networking of the above-mentioned enterprises or organizations, computer equipment and network communication systems in schools, homes and even individuals have long been indispensable for transmitting or receiving all aspects of information in our lives. Tool of. Φ Once various computer equipment is to be used to transmit and receive message data through the network communication system, there must be a fixed data transmission agreement between each data transmission and receiving node (Node) such as a terminal device or server. Taking the current known Ethernet network (E t h e r n e t) architecture as an example, the access method of the media is carrier-aware multiple in-out collision detection

Detection; CSMA / CD) is the IEEE 802.3 protocol. In other words, when each node on the network wants to transmit data, it must first detect if other nodes on the network cable are using the network (Carrier Sense). If the cable is detected to be idle, the node can send data to the cable and continue to monitor the cable signal. Since Ethernet is a broadcast medium, there is no concept of priority, so there may be Two or more nodes send data to the cable (Mu 11 ip 1 e A ccess). If a plurality of different nodes send data at the same time, a data collision occurs, and the nearest network node near the place where the collision occurs will detect this collision and send a Jamming signal, and the collided nodes will stop. Data transmission (Co 1 1 isi on Detecti ο η). Collision of multiple nodes will wait for a period of time and then retransmit to avoid continuous collisions. The time each node waits will be randomly generated. The same frame can be retransmitted up to 16 times. If it still cannot be completed, it will be abandoned. , And send an error message to the upper layer protocol .. According to the previous description, when data is transmitted on the network, it is transmitted in the form of a packet. Generally, the size of a data packet through the above communication protocol is 64 to 1518 bytes, of which the destination address (Destination Address) Source address (7 bytes each), Length field (2 bytes), Data (data) block (46 to 1500 bytes) and frame order The check (Frame Check Sequence) blocks 4 bytes. When each node on the network wants to receive data packets sent from the network

Because the central buffer memory list is being provided for other units — and then the data is ϊI. Cheng Qiansuo's Hidden = Will ~ Passed: Filled with 4 pieces of data ^ 疋 疋 疋 有 有 疋 #% will be different / Yuan, j packet 偯 ^ 疋 This data often happens: after collision 4 Each of the 2000 packets is large, and f is inferior. Asia is not expected. The taxi must be ranked after the type of the packet in this section. Because of this, in the system information processing unit, it should be eased from time to time, if the number of nets is less than 158, the net will be funded and the net is possible. If the data card with a longer data length is converted into a parallel master memory unit and received by the unit, the unit will occupy the unit and process it, and when the master memory unit data packet is obtained, it will be a unit of 15 1 8 bits. The packet length is transmitted in a timely manner without mixing the network data. An important lesson of transmission is the same as the aforementioned data, which will cause abnormal byte data, which is 2000 bytes. It has a certain meaning. The memory unit bus is located at the (Network point. If it is of the type, after using the bus, it may not be possible. First, the bytes transmitted in the memory unit bus are sent out. Save costs, because if the group cannot reach the master memory single, calculate the current packet between the 64 states and transfer the data. In addition, if the collision occurs and the packet length is sent out, the master memory list will be used. The amount of the entire node

The master-memory list is normal. This general buffer is recorded in the buffer. The 4 tuples are located at the slow critical point and sent to the main network for survival, and the 'false element preset material is expected to cause a memory sheet in the system to cause 1 5 1 8 flush memory' to avoid the occurrence of the data in the memory sheet. The useless storage of this receiver is due to the main

In step S 2 10, the data length calculation module 43 is caused to determine whether the data byte in transmission is the tail of the data packet. If it is, proceed to step S 2 1 1; otherwise, proceed to step S 2 1 5 . In step S211, a data tail index 1 03 is written in the register to allow the network communication system connection module 40 to determine the end point of the data packet to write to the buffer memory unit. In the buffer area of 41, step S 2 1 2 is performed. In step S212, the current byte length of the data packet data byte can be calculated through the data trailing indicator ι03 and the address of the reading indicator 102, and then proceed to step S 2 1 3. Therefore, a clock is added in step S21 3 to separate different data packet delays, and then step S 2 1 4 is performed. The breaking module 44 compares the buffer packet data length and the preset length as the trigger length in step S214, and causes the trigger length to memorize the valid data byte length and the packet trigger length in the unit 41 and compare them with each other and obtain The minimum value.
