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

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, 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 different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length 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 the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the 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.

Referring to fig. 5, a method for determining a device access address according to an embodiment of the present invention is shown.

The step flow chart of the first embodiment may specifically include the following steps:

step 501: determining the level of a target autonomous cloud of a device to be accessed in the autonomous network.

If the device needs to be allocated with a device access address when accessing the autonomous network, the device access address needs to be determined according to the method in the embodiment of the invention. When the equipment determined by the method in the embodiment of the invention is accessed into the address access equipment, not only can the equipment in the autonomous cloud communicate with each other, but also the data can be transmitted mutually; and the devices of different autonomous clouds can also communicate with each other to transmit data.

The method for accessing the device address provided by the embodiment of the invention is applied to an autonomous network based on an internet of view, as shown in fig. 6, the autonomous network comprises a plurality of layers of autonomous clouds, and each layer of autonomous cloud comprises at least one autonomous cloud. Each autonomous cloud comprises an autonomous server, and the autonomous server is a brain of the autonomous cloud. Each autonomous cloud comprises a sub-control server, if the autonomous cloud is single autonomous, a boundary router does not need to be set, and if the autonomous cloud is multi-autonomous, a boundary router needs to be set.

An autonomous network: the autonomous network is a distributed centralized control network, and comprises a plurality of autonomous clouds distributed according to layers in the video network, namely, the whole network structure of the video network is formed by mutually connecting a plurality of structural units called autonomous clouds, and the autonomous clouds present a hierarchical structure when being mutually connected.

Autonomous cloud: the autonomy cloud is a basic structural unit for forming the video network and is also a minimum unit for enabling the video network to normally operate.

The boundary router: the boundary router is a data forwarding node of the autonomous cloud, can be connected to two layers of autonomous clouds at the same time, and can realize data forwarding across the autonomous clouds.

A sub-control server: a forwarding node in the autonomous cloud.

In addition, the autonomous cloud also comprises one sub-control micro cloud and at least one main micro cloud.

In the embodiment of the present invention, an example in which an autonomous network includes 4 hierarchies is described.

Step 502: and determining the position of the equipment accessed into the target autonomous cloud.

The position is a master control micro cloud in the target autonomous cloud or a sub-control micro cloud in the target autonomous cloud.

Step 503: and determining the corresponding logical address of the equipment according to the hierarchy and the position.

Wherein the logical address includes: a local logical address, a logical address prefix, and a global logical address.

Specifically, the local logical address may be determined by location, and the logical address prefix and the global logical address may be determined by hierarchy. The device can be accessed into a main control micro cloud in the target autonomous cloud and can also be accessed into a sub-control micro cloud in the target autonomous cloud, and corresponding local logic addresses are different when the device is accessed into the main control micro cloud and the sub-control micro cloud.

Step 504: and determining the corresponding logical port address of the equipment.

All network interfaces of devices connected to the video network will be assigned a logical port address of one when the device is networked. This address is unique within the connected clouds (master or slave). The logical port address can be represented by a hexadecimal numerical value, and the value range is 0x01-0xfe, namely a total of 254 network interfaces can be accessed in the same micro cloud.

Step 505: and generating an access address of the equipment according to the logical address and the logical port address.

The method for determining the access address of the equipment provided by the embodiment of the invention determines the level of a target autonomous cloud of the equipment to be accessed in an autonomous network; determining the position of the device accessed into the target autonomous cloud, and determining a logic address corresponding to the device according to the hierarchy and the position; determining a logical port address corresponding to the equipment; and generating the access address of the equipment according to the logical address and the logical port address, and automatically and efficiently generating a unique equipment access address for the equipment accessing the video network.

Referring to fig. 7, a method for determining a device access address according to an embodiment of the present invention is shown.

The device access address determined in the embodiment of the invention mainly comprises a logic address and a logic port address, wherein the logic address specifically comprises the following components: the local logical address, the logical address prefix and the global logical address. The logic address is used for positioning a network interface of the equipment, and if the equipment uses a plurality of network interfaces to access the video network, each network interface has an independent logic address; all network interfaces of the devices connected to the video network assign a logical port address to the device when the device is networked. The steps 701 to 705 are the procedure of determining the logical address, and the step 706 is the procedure of determining the logical port address.

Step 701: determining the level of a target autonomous cloud of a device to be accessed in the autonomous network.

The device access address method provided by the embodiment of the invention is applied to an autonomous network based on a video network, the autonomous network comprises a plurality of layers of autonomous clouds, each layer of autonomous cloud comprises at least one autonomous cloud, each autonomous cloud comprises an autonomous server, specific structures and functions of the autonomous network can refer to relevant descriptions in the first embodiment, and details are not repeated in the embodiment of the invention.

In the embodiment of the present invention, an example in which an autonomous network includes 4 layers of autonomous clouds is described. It should be noted that, a specific hierarchy of the autonomous cloud included in the autonomous network may be laid out by a person skilled in the art according to actual needs, for example, the specific hierarchy may be set to be 3 layers, 5 layers, or more, and the like, which is not particularly limited in the embodiment of the present invention.

Step 702: and determining the position of the equipment accessed into the target autonomous cloud.

The position is a master control micro cloud in the target autonomous cloud or a sub-control micro cloud in the target autonomous cloud. One autonomous cloud comprises a main control micro-cloud and at least one sub-control micro-cloud.

Step 703: and determining the local logical address corresponding to the equipment according to the position.

All network interfaces of the devices connected to the video network are assigned to a 16-bit local logical address when the devices are connected to the network, and the local logical address is unique inside an autonomous cloud accessed by the devices and is generally represented by a 16-bit system.

Specifically, when the location is the master control clout, the local logical address is a logical port address of the interface in the master control clout; when the position is the sub-control micro cloud, the local logic address is a combination of a logic port address of an uplink interface of the sub-control server in the main control micro cloud and a logic port address of a network interface in the sub-control micro cloud, wherein the network interface is a network interface distributed for the equipment by the view network.

Step 704: and determining the corresponding logical address prefix of the equipment according to the hierarchy.

Each autonomous cloud is assigned a logical address prefix according to its location throughout the video network. The logical address prefix is divided into 3 segments. Logical address prefixes are typically denoted by 16. Such as 0x12D4-0x56C8-0xA 07F. The device access address contains a logical address prefix, that is, a logical address prefix assigned to the autonomous cloud.

A preferred way to determine the logical address prefixes corresponding to devices according to hierarchy is to:

determining each lower level of the levels layer by layer in the autonomous network;

sequentially combining access logic addresses corresponding to each lower level from bottom to top according to the hierarchy to obtain a logic address prefix corresponding to the equipment; the access logic address corresponding to the hierarchy is a local logic address of a boundary router in the autonomous cloud of the hierarchy, wherein the local logic address is used when the autonomous cloud of the previous hierarchy accesses the autonomous cloud of the hierarchy.

Assuming that the determined hierarchy is 1 and the autonomous network comprises 4 autonomous clouds, each lower hierarchy of the hierarchy 1 is 2, 3 and 4, and combining the access logical addresses corresponding to the lower hierarchies in sequence from bottom to top is to combine the access logical addresses corresponding to the 4 hierarchies, the access logical addresses corresponding to the 3 hierarchies and the access logical addresses corresponding to the 2 hierarchies in sequence.

For example: the logical address prefix of the layer 1 autonomous cloud has the composition rule of < accessed logical address 4> - < accessed logical address 3> < accessed logical address 2 >; the logical address prefix of the layer 2 autonomous cloud has the composition rule of < access logical address 4> - < access logical address 3> 0000; the logical address prefix of the 3 rd layer autonomous cloud has the composition rule of < access logical address 4> -0000-; the composition rule of the logical address prefix of the layer 4 autonomous cloud is 0000-.

Wherein, the < access logic address 2> represents the local logic address of the boundary router used when the layer 1 autonomous cloud is accessed to the layer 2 autonomous cloud in the layer 2 autonomous cloud; the < access logical address 3> represents a local logical address of a boundary router used when the layer 2 autonomous cloud is accessed to the layer 3 autonomous cloud in the layer 3 autonomous cloud; and the < access logical address 4> represents a local logical address of a boundary router used by the layer 3 autonomous cloud when accessing the layer 4 autonomous cloud in the layer 4 autonomous cloud.

Step 705: and determining the global logic address corresponding to the equipment according to the hierarchy.

The global logical address is divided into 4 segments, and the global logical address is usually represented by 16. Such as 0x12D4-0x56C8-0xA07F-0x3B 9E.

One way to determine the device's corresponding global logical address, preferably by hierarchy, is as follows:

selecting a corresponding address field from the logical address prefix of the target autonomous cloud according to the hierarchy;

and combining the selected address segment with the local logic address of the network interface to obtain the global logic address corresponding to the equipment.

For example: the global logical address of the layer 1 autonomous cloud has a composition rule of (logical address prefix of the autonomous cloud > - < local logical address of the network interface >); the global logic address in the layer 2 autonomous cloud has a composition rule of < first 2 segments of the logical address prefix of the autonomous cloud > < local logic address of network interface > -0000; the global logic address in the 3 rd layer autonomous cloud has the composition rule of < segment 1 of the logical address prefix of the autonomous cloud > < the local logic address of the network interface > -0000-; the global logic address in the layer 4 autonomous cloud has a composition rule of < local logic address of network interface > -00000000-.

Step 706: and determining the corresponding logical port address of the equipment.

All network interfaces of devices connected to the video network will be assigned a logical port address of one when the device is networked. The address is unique inside the connected micro cloud (master micro cloud or sub-control micro cloud), and is represented by a 16-system numerical value.

Step 707: and generating an access address of the equipment according to the logical address and the logical port address.

The specific representation mode of each part of the equipment access address determined by the embodiment of the invention is shown in table 1:

the method for determining the access address of the equipment provided by the embodiment of the invention determines the level of a target autonomous cloud of the equipment to be accessed in an autonomous network; determining the position of the device accessed into the target autonomous cloud, and determining a logic address corresponding to the device according to the hierarchy and the position; determining a logical port address corresponding to the equipment; and generating the access address of the equipment according to the logical address and the logical port address, and automatically and efficiently generating a unique equipment access address for the equipment accessing the video network.
