as shown in fig. 9, the network interface module 901, the switching engine module 902, the CPU module 903, and the disk array module 904 are mainly included.

The network interface module 901, the CPU module 903, and the disk array module 904 all enter the switching engine module 902; the switching engine module 902 performs an operation of looking up the address table 905 on the incoming packet, thereby obtaining the direction information of the packet; and stores the packet in a corresponding queue of the packet buffer 906 based on the packet's steering information; if the queue of the packet buffer 906 is nearly full, discard; the switching engine module 902 polls all packet buffer queues for forwarding if the following conditions are met: 1) the port send buffer is not full; 2) the queue packet counter is greater than zero. The disk array module 904 mainly implements control over the hard disk, including initialization, read-write, and other operations on the hard disk; the CPU 903 is mainly responsible for protocol processing with an access switch and a terminal (not shown), configuring an address table 905 (including a downlink protocol packet address table, an uplink protocol packet address table, and a data packet address table), and configuring the disk array module 904.

The access switch:

as shown in fig. 10, the network interface module (downstream network interface module 1001 and upstream network interface module 1002), the switching engine module 1003, and the CPU module 1004 are mainly included.

Wherein, the packet (uplink data) coming from the downlink network interface module 1001 enters the packet detection module 1005; the packet detection module 1005 detects whether the Destination Address (DA), the Source Address (SA), the packet type, and the packet length of the packet meet the requirements, if so, allocates a corresponding stream identifier (stream-id) and enters the switching engine module 1003, otherwise, discards the stream identifier; the packet (downstream data) coming from the upstream network interface module 1002 enters the switching engine module 1003; the incoming data packet of the CPU module 1004 enters the switching engine module 1003; the switching engine module 1003 performs an operation of looking up the address table 1006 on the incoming packet, thereby obtaining the direction information of the packet; if the packet entering the switching engine module 1003 goes from the downstream network interface to the upstream network interface, the packet is stored in the queue of the corresponding packet buffer 1007 in combination with the stream-id; if the queue of the packet buffer 1007 is nearly full, it is discarded; if the packet entering the switching engine module 1003 does not go from the downlink network interface to the uplink network interface, the data packet is stored into the queue of the corresponding packet buffer 1007 according to the guiding information of the packet; if the queue of the packet buffer 1007 is nearly full, it is discarded.

The switching engine module 1003 polls all packet buffer queues, which in this embodiment of the present invention is divided into two cases:

if the queue is from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the port send buffer is not full; 2) the queued packet counter is greater than zero; 3) and obtaining the token generated by the code rate control module.

If the queue is not from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) the port send buffer is not full; 2) the queue packet counter is greater than zero.

The rate control module 1008 is configured by the CPU module 1004 to generate tokens for packet buffer queues from all downstream network interfaces to upstream network interfaces at programmable intervals to control the rate of upstream forwarding.

The CPU module 1004 is mainly responsible for protocol processing with the node server, configuration of the address table 1006, and configuration of the code rate control module 1008.

Ethernet protocol conversion gateway：

As shown in fig. 11, the system mainly includes a network interface module (a downlink network interface module 1101 and an uplink network interface module 1102), a switching engine module 1103, a CPU module 1104, a packet detection module 1105, a rate control module 1108, an address table 1106, a packet buffer 1107, a MAC adding module 1109, and a MAC deleting module 1110.

Wherein, the data packet coming from the downlink network interface module 1101 enters the packet detection module 1105; the packet detection module 1105 detects whether the ethernet MAC DA, the ethernet MAC SA, the ethernet length or frame type, the video network destination address DA, the video network source address SA, the video network packet type, and the packet length of the packet meet the requirements, and if so, allocates a corresponding stream identifier (stream-id); then, the MAC deleting module 1110 subtracts MAC DA, MAC SA, length orframe type (2byte) and enters the corresponding receiving buffer, otherwise, discards the MAC;

the downlink network interface module 1101 detects the sending buffer of the port, and if there is a packet, acquires the ethernet MAC DA of the corresponding terminal according to the video networking destination address DA of the packet, adds the ethernet MAC DA of the terminal, the MACSA of the ethernet coordination gateway, and the ethernet length or frame type, and sends the packet.

The other modules in the ethernet protocol gateway function similarly to the access switch.

A terminal:

the system mainly comprises a network interface module, a service processing module and a CPU module; for example, the set-top box mainly comprises a network interface module, a video and audio coding and decoding engine module and a CPU module; the coding board mainly comprises a network interface module, a video and audio coding engine module and a CPU module; the memory mainly comprises a network interface module, a CPU module and a disk array module.

1.3 devices of the metropolitan area network part can be mainly classified into 3 types: node server, node exchanger, metropolitan area server. The node switch mainly comprises a network interface module, a switching engine module and a CPU module; the metropolitan area server mainly comprises a network interface module, a switching engine module and a CPU module.

2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (e.g. various protocol packets, multicast data packets, unicast data packets, etc.), there are at most 256 possibilities, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses.

The Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA).

The reserved byte consists of 2 bytes.

The payload part has different lengths according to types of different datagrams, and is 64 bytes if the type of the datagram is a variety of protocol packets, or is 1056 bytes if the type of the datagram is a unicast packet, but is not limited to the above 2 types.

The CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of a Label of Multi-Protocol Label switching (MPLS), and assuming that there are two connections between a device a and a device B, there are 2 labels for a packet from the device a to the device B, and 2 labels for a packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
