Background
With the continuous development of networks and communication technologies, the capability requirements of data transmission of network devices and data distribution of data networks are higher and higher.
In a communications network, since some network data content is acquired by multiple end users at the same time, the data transmission network needs to "copy" multiple copies of the network data content and then transmit the copies to different user addresses. In the existing network data distribution method, a CPU is responsible for packaging and sending network data contents to be transmitted to a plurality of users, i.e. completing the processes of "copying" and transmitting. The problem of this method is that the process of packaging and sending occupies a lot of resources of CPU, which is not favorable for improving the efficiency of data distribution, especially when thousands of users need to access network data, the situation of resource occupation is more obvious, thus leading to serious problem of network delay.
Yet another existing approach is to use a content distribution network to address the problem of packet packaging and delivery. A Content Delivery Network (CDN) is a special Network Content Delivery Network that is mainly built on the internet, and the principle of the CDN technology is to deliver Network data Content to an edge server closest to a Network user, so that the user can obtain required Network Content from the closest server at the fastest speed.

After receiving the data packet, the packet store-and-forward module 22 stores the data packet into theDDR4 storage module 23, and when the distribution of the current frame data packet is completed, reads the next frame data packet from theDDR4 storage module 23.

If the distribution address of the data packet points to the CPU port, the packet store-and-forward module 22 sends the data packet to the first packet selection module 24; when the distribution address of the data packet is judged to point to N terminals in an external network, the content of the data packet is copied into N parts, the distribution destination address of the data packet is obtained according to the distribution rule, the destination address of any part of the data packet is modified into any distribution destination address and then is distributed, and meanwhile, the next distribution destination address is obtained; wherein the distribution is to send the data packet with the destination address information modified to the second packet selection module 27. And when the N data packets are distributed, ending the distribution of the data packet of the frame.
Fig. 3 is a schematic diagram of a data packet priority processing process in an application system of a network data distribution method according to embodiment 1 of the present invention. Idle in fig. 3 indicates the first packet selection module 24 in the system, and rdlntpkt indicates that the first packet selection module 24 is in a read interrupt packet state; RdCfgPkt indicates that the first packet selection module 24 is in a read configuration packet state; rdunnedpkt indicates that the first packet selection module 24 is in a read non-UDP packet state; RdUdPkt indicates that the first packet selection module 24 is in a state of reading a UDP packet for transparent transmission; rdciuppkt indicates that the first packet selection module 24 is in a read distribution UDP packet state.
The following describes how to implement the process of forwarding data packets according to priority in the first packet selection module 24 in conjunction with fig. 3. When the first packet selection module 24 receives an interrupt packet, a configuration packet, a non-UDP packet, a transparent UDP packet, and a distribution UDP packet, it is necessary to perform priority ordering on these data packets in order to ensure the network data quality requirement, and then sequentially send the data packets to the internal IP core module 25 according to the ordered priorities; the logic packet sending module 29 sends an interrupt packet, the configuration packet identification module 26 reads the configuration logic register module 28 and sends the configuration packet, and the packet storage and forwarding module 22 sends a non-UDP packet, a transparent UDP packet, and a distribution UDP packet. The first packet selecting module 24 receives the priority configuration packet read by the configuration packet identifying module 26 from the configuration logic registering module 28, and sets the priority of the data packet in the first packet selecting module 24 according to the priority rule in the priority configuration packet; the priority order of the data packets is as follows in sequence: an interrupt packet, a configuration packet, a non-UDP packet, a transparent UDP packet and a distribution UDP packet.
The inner IP core module 25 receives the data packet from the first packet selection module 24 and performs CRC detection on the data packet. If the data packet is detected to have an error, an error identifier is sent to the logic packet sending module 29, and if the data packet is not detected to have an error, the data packet is sent to the CPU port according to the priority.
Fig. 4 is a schematic diagram of a preferred configuration packet structure provided in embodiment 1 of the present invention. The configuration packet comprises a source address, a destination address, a packet type, a packet sequence number, an operation code, an operation address, an operation length, operation data and frame check; wherein, the source address is the MAC address of the CPU network port; the destination address is a purchased legal MAC address; the packet type is the ASCII code of the company; the packet serial number is a cyclic number of 0-255, and the CPU can continuously read and write the data packet by using the packet serial number; the operation code is used for indicating the read, write or interrupt state of the data packet; the operation address is automatically accumulated from the address inside the logic device when in burst mode; the operation length is the length of an operation code, and the legal value of the operation length is from 1 to 1024; the operation data is used for transmitting the data by the CPU when the logic device needs to write information into the register, and transmitting the data by the logic device when the logic device reads the information of the register; the frame check is a MAC frame check.
Further, in this embodiment of the present invention, the distribution address is a distribution destination address of the data packet included in the distribution rule. When the distribution address includes at least two distribution destination addresses and the distribution destination addresses are linked into a ring, in order to avoid a situation that the same packet of network data content is repeatedly sent all the time due to an error occurring in the configuration packet, the packet store-and-forward module 22 automatically performs a loopback test to verify whether the distribution destination addresses are linked into a ring, and when the distribution destination addresses are detected to be linked into a ring, the packet store-and-forward module 22 stops sending the data packet.
Specifically, in the embodiment of the present invention, the maximum forwarding number of the packet store-and-forward module 22 is set to 2047 times, it can be understood that, when the packet store-and-forward module 22 forwards once, the value of the counter in the data distribution system is increased by one, and when the forwarding number of the packet store-and-forward module 22 is greater than 2047 times, the data distribution system ends current data forwarding and obtains a new network data packet again for transmission.
In another preferred embodiment, when the CPU utilizes the CPU port to go through the distribution system to the external network, the CPU port transmits the internal data packet sent by the CPU to the internal IP core module 25, and the internal IP core module 25 performs CRC detection on the internal data packet. If the internal data packet is detected to have an error, an error identifier is sent to the logic packet sending module 29; if no error is detected in the internal data packet, the internal data packet is sent to the configuration packet identification module 26. The configuration packet identification module 26 detects whether the internal data packet is a configuration packet according to the MAC address of the internal data packet, and if the internal data packet is a configuration packet, detects whether the configuration packet has an error; if the configuration packet is detected to have an error, an error flag is sent to the logic packet sending module 29, and if the configuration packet is not detected to have an error, the configuration packet is extracted and sent to the configuration logic registering module 28. If it is detected that the internal data packet is a data packet, the data packet is sent to the second packet selection module 27. The second packet selecting module 27 performs priority sorting on the received data packets according to the priority rule information obtained from the configuration logic registering module 28, and then sends the received data packets to the externalIP core module 21 according to the priority order and enters the external network.
Referring to fig. 5, a schematic structural diagram of a network data distribution apparatus provided in embodiment 2 of the present invention is shown, where the apparatus includes:
