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.

Based on the characteristics of the video network, one of the core concepts of the embodiments of the present invention is provided, and a simplified video network address is received by a local video network terminal following a video network protocol, and if the simplified video network address contains a preset coincidence, the simplified video network address is restored to a complete target video network address in the same ethernet network by using the local video network address of the local video network terminal, and then a server is requested to access the target video network terminal according to the obtained complete target video network address, and the server accesses the target video network terminal in the same ethernet network as the local video network terminal according to the target video network address.

Referring to fig. 5, fig. 5 is a flowchart illustrating steps of a method for accessing a video network terminal according to an embodiment of the present invention, where the method may be applied to a video network, where the video network terminal includes a local video network terminal and a target video network terminal, and the method specifically includes the following steps:

and step 501, the local video network terminal acquires a simplified video network address.

In the step, the simplified video network address is the video network address input by the local video network terminal by the user, and the simplified video network address corresponds to the target video network terminal which the user needs to access.

In the step, after a user inputs the simplified video networking address at a browser or a web end, a dns request data packet is generated, the data packet contains the simplified video networking address, and the local video networking terminal captures the dns request data packet, so as to acquire the simplified video networking address in the data packet.

Step 502, when the simplified video network address contains a preset symbol, the local video network terminal extracts the local video network address.

In this step, the local video network address extracted by the local video network terminal is the video network address of the local video network terminal. Since the internet-of-view address is a string of decimal digits of a fixed number, for example, in a 64-digit internet-of-view, the internet-of-view address is represented by 20 decimal digits, and if the target internet-of-view terminal is on the same ethernet as the local internet-of-view, the internet-of-view address of the target internet-of-view terminal is also a string of decimal digits of a fixed number. The local network-of-sight address can be divided into a prefix portion and a subsequent portion, wherein the prefix portion is any portion which is identical to any network-of-sight address in the same ethernet with the local network-of-sight terminal, and the subsequent portion is the portion of the local network-of-sight address which is left after the prefix portion is removed. When a target video network terminal in the same Ethernet with the local video network terminal needs to be accessed, the prefix part can be replaced by the preset symbol, so that a user only needs to input the preset symbol and data which can represent the subsequent part of the video network address of the target video network terminal, when the local video network terminal detects the preset symbol, the simplified video network address input by the user can be judged to be the video network address used for accessing the target video network terminal in the same Ethernet with the local video network terminal, and reduction processing is needed, so that the subsequent step can be triggered. Because the user only needs to input the preset symbol and the data representing the subsequent part of the target video networking terminal video networking address, the digital input quantity and the memory quantity of the user can be greatly reduced, and convenience is brought to the user.

Optionally, the preset sign bit is underlined _. For example, the local view network address is 00010002100260500000, and the addresses in the same ethernet network start with 0001000210, this 0001000210 is a prefix portion, which can be replaced with a preset symbol underlined _ and the target view network address can be simplified to _ 0260500000 as a simplified view network address, which the user can input.

And 503, the local video network terminal restores the simplified video network address to a target video network address according to the local video network address.

In the step, the local video network address sequentially comprises the Ethernet numbers of each level from the root node video network to the local Ethernet from head to back, so that the prefix part can be obtained according to the local video network address, and the prefix part can be added to the front end of the digital section of the simplified video network address, so that the simplified video network address is restored to the target video network address with the same prefix part as the local video network address. In addition, if the local ethernet network is also the next level ethernet network, the end of the local video network address also includes at least 1 set of all-zero ethernet numbers.

And step 504, the local video network terminal accesses the target video network terminal by adopting the target video network address.

In the step, network access is carried out through the restored target video network address, and communication of the target video network terminal corresponding to the target video network address can be achieved.

In practical application, the local video network terminal generates an access application instruction according to the target video network address obtained by reduction, and sends the access application instruction to the video network server so as to request the video network server to control access to the target video network terminal.

The method for accessing the video network terminal provided by the embodiment of the invention is applied to the video network, utilizes the characteristic that the video network addresses of the video network terminals in the same Ethernet in the video network have a common prefix part, when the local video network terminal acquires the simplified video network address containing the preset coincidence, the simplified video network address is restored to the target video network address through the local video network address of the local video network terminal, then the target video network terminal is accessed by adopting the target video network address, thereby realizing the access to the target video network terminal which is in the same Ethernet with the local video network terminal, in the process, the user only needs to input the simplified video network address containing the preset coincidence at the local video network terminal, and the user does not need to input a long string of numbers in the local video network terminal, thereby providing convenience for the user.

Optionally, after step 502, further comprising: and when the simplified video network address does not contain a preset symbol, the local video network terminal takes the simplified video network address as a target video network address.

In this step, if the simplified video networking address does not include a preset symbol, it indicates that the simplified video networking address does not need to be restored, and thus the local video networking terminal takes the simplified video networking address as a target video networking address.

In view of the fact that the video network is a tree structure formed by a plurality of ethernet networks, for the tree structure formed by a plurality of subnets, the video network address of the existing video network is designed to be a multilayer structure, and each layer of structure represents the number of the corresponding ethernet network by a fixed number field of a first preset threshold digit, namely each layer represents one level. For example, the address 64 for the internet of view is a 4-layer structure, i.e. 4 sets of 5-bit numbers, each set of five-bit numbers corresponds to an ethernet number, and there are 20 numbers in total. The 20-digit numbers are divided into 4 groups and are marked as A-B-C-D. The root node of the ethernet tree structure is ethernet a corresponding to a, the child node of a is ethernet B corresponding to B, the child node of B is ethernet C corresponding to C, and the child node of C is ethernet D corresponding to D. If a group of numbers are all zero, the video network address is finished in the Ethernet, and the next-level access is not needed, so the all-zero layers can be simplified, and the video network address input quantity of the target video network terminal when the user accesses the local video network terminal in the same Ethernet is further reduced.

The video network address of the target video network terminal can be divided into a prefix part and a distinguishing part, the prefix part is also the prefix part of the local video network address, and the distinguishing part is the part of the video network address of the target video network terminal after the prefix part is removed. If the target video network terminal and the local video network terminal are in the same Ethernet, when the user inputs the simplified video network address, the Ethernet number of all zeros in the distinguishing part can be removed. In this step, because any one of the addresses of the internet of view has a root node, that is, has a corresponding upper-level ethernet number, the front-end ethernet number in the subsequent part cannot be all zero, so the all-zero ethernet number only appears at the end of the distinct part, and represents the number of the ethernet corresponding to the next-level ethernet or the child node of the next-level ethernet that does not access the current ethernet, and thus the number of the part of ethernet can be simplified and saved. And because the video network address has a predetermined level and each layer of Ethernet is a digital string with a first preset threshold digit, the Ethernet number of the tail end all zeros of the saved distinguishing part is re-zero-complemented to the first preset threshold digit to be restored into the following part.

For example, if the internet-of-view address of the target internet-of-view terminal is 00010002100260500000, and the address of the target internet-of-view terminal in the same ethernet all start with 0001000210, this 0001000210 is a prefix portion, and can be replaced with a preset symbol such as underline — and the internet-of-view address can be simplified to _ 0260500000, since the fourth group number field is all 0, which represents an address of the third layer, only the third group number is valid when accessing the target internet-of-view terminal, so that 0 of the fourth group can be further omitted, and the simplified internet-of-view address is obtained as _02605, and the user inputs the simplified internet-of-view address.

Likewise, considering that the view network address has predetermined levels, each level being a string of numbers having a first preset threshold number of bits, optionally, when the user inputs the reduced view network address, zeros preceding the first non-zero numbers of the discriminating portion are removed. When the video network address is subsequently restored, a plurality of zeros are added to the first digit of the simplified video network address until the number of the Ethernet number where the first non-zero digit of the simplified video network address is located reaches a first preset threshold value, and the Ethernet number can be restored to the distinguishing part, so that the input amount of a user accessing the same Ethernet can be further reduced.

For example, if the view network address of the target view network terminal is 00010002100260500000, and the address in the same ethernet network starts with 0001000210, this 0001000210 is a prefix portion, and can be replaced with a preset symbol such as underline _ and the target view network address can be simplified to _ 0260500000, because the fourth group is all 0, which represents an address of the third layer, only the third group of numbers is valid when accessing the target view network terminal, so that 0 of the fourth group can be further omitted to obtain _02605, 0 before the first non-zero number "2" in the group of addresses is omitted to obtain _2605, which is used as a simplified view network address, and the user inputs the simplified view network address.

Optionally, when the user inputs the reduced view networking address, the number segments between different levels are distinguished, for example, a blank space is distinguished, so that the next level of ethernet view networking address taking the child node of the same ethernet as the root node can be reduced.

Based on the simplified view networking address, in a preferred embodiment of the present invention, step 503 specifically includes steps 511 to 515.

And 511, the local video network terminal extracts the numbers in the simplified video network address, segments the numbers and generates a first video network address comprising at least one number segment.

In the step, because the user may input other data except the numbers and the preset symbols by hand when inputting the simplified video networking address, the user can extract the simplified video networking address without being influenced by other data as long as the user inputs the Ethernet number corresponding to the target video networking address included in the simplified video networking address.

The step 511 can include steps 521 ~ 523.

And step 521, traversing the numbers behind the preset symbols in the simplified video network address, and generating a number string.

The step is that the numbers behind the preset symbols in the simplified video network address are extracted from the head to the back, and a number string is formed.

Step 522, judge whether there is a space in the simplified video network address.

If the target video network terminal is in the same Ethernet with the local video network terminal address and in a network structure of a lower hierarchy, namely the video network address of the target video network terminal is the Ethernet led out by the Ethernet node where the local video network address is located. Thus, in this step 521, it is determined whether the simplified internet-of-view address entered by the user is at the same level as the local internet-of-view address or a lower level of the internet-of-view address by means of a space.

Step 523, if there is a blank space in the simplified video network address, correspondingly segmenting the extracted numeric string according to the position of the blank space.

In this step, if it is determined that there is a blank in the simplified video networking address, it is indicated that the video networking address of the target video networking terminal is a video networking address of a lower hierarchy than the local video networking address, and the corresponding end portion has a multi-hierarchy structure, and because each hierarchy structure in the video networking address has a digit number of a first preset threshold, the extracted digit string needs to be correspondingly segmented according to the position of the blank to correspond to the corresponding hierarchy structure, and then the digit number of each digit segment can be adjusted by the subsequent steps, so that each digit segment can reach the digit number of the first preset threshold.

Step 524, if there is no space in the simplified video network address, the extracted number string is used as a number segment.

In this step, if it is determined that there is no blank space in the simplified video network address, it indicates that the video network address in the target video network is not only in the same ethernet as the local video network address, but also in the same level as the local video network address, and therefore the extracted number string is directly used as 1 number field.

Step 525, generating a first video network address based on the number field.

This step takes the digital field from step 523 or step 524 as the first video network address.

And 512, verifying the first video network address by adopting a first preset threshold value, and converting the verified first video network address into a second video network address, wherein the second video network address is a video network address of which the digit number of each digit section reaches the first preset threshold value.

Each level in the video network address has an ethernet number with a first preset threshold number of digits. In the step, it is required to determine whether the number digit of each digit section in the first video network address reaches a first preset value, because each digit section in the first video network address corresponds to the ethernet number of the corresponding hierarchy, if the number digit of some digit sections does not reach a first preset threshold, it is indicated that a plurality of 0 s are arranged in front of the ethernet number of the corresponding hierarchy, and in order to convert the digit section into the ethernet number of the corresponding hierarchy, how much the difference between the number digit of the digit section and the first preset threshold is, how many 0 s are required to be added in front of the digit section, so that the number digit of the digit section reaches the first preset threshold, and the first video network address is converted into the second video network address; and if the digit number of each digit section in the first preset address reaches a first preset threshold value, directly recording the first video network address as a second video network address.

And 513, acquiring a prefix part in the local video network address, wherein the prefix part is the same as any video network address of the local video network terminal in the same ethernet.

Since the local networking address sequentially comprises the ethernet numbers of each level from the root node ethernet to the local ethernet from head to back, the prefix part in the local networking address can be obtained, and optionally, the step 513 comprises steps 531 to 533.

And 531, judging the video networking address hierarchy to which the local video networking address belongs.

In this step, if the local ethernet has a next-level ethernet, the next-level ethernet number in the local networking address is all zero, if the local ethernet has a next-level ethernet, the next-level ethernet number in the local networking address is also all zero, and if the local ethernet has a next-level ethernet, the situation is similar. Each Ethernet number is a first preset threshold value, so that the video networking address level of the local video networking address can be judged according to the number of the Ethernet number groups of which the local video networking address tail end is all zero, Q is the total number of the video networking address levels, the number of the video networking address tail ends which are continuously 0 is detected forwards, an integer obtained by dividing the number by the first preset threshold value is P, and the video networking address level to which the local video networking address belongs is Q-P.

For example, taking a 64-bit internet address with 20-bit digits as an example, the total number of the internet address hierarchy levels is 4, and the determination method is as follows: the number of consecutive 0's starting from the last digit of the 20 digit video network number is viewed. If the number is less than 5, the address is an address of a fourth layer; if the number is less than 10 and not less than 5, the address is an address of a third layer; if the number is less than 15 and not less than 10, the address is an address of the second layer; if the number is less than 20 and not less than 15, this is an address of the first layer.

Step 532, extracting the number segment of the local internet of view address located at the front side of the internet of view address hierarchy as the prefix part.

In this step, the local video network address level corresponds to a digital segment from [ (the video network address level-1) × the first preset threshold +1] bits to (the video network address level × the first preset threshold) bits.

And the number field of the local video network address positioned at the front side of the affiliated video network address level is the number field of the first bit to [ (affiliated video network address level-1) x first preset threshold ] bit in the local video network address as the prefix part.

Step 513, add the prefix portion to the second video network address to obtain a third video network address.

In this step, the prefix part shared by the same ethernet obtained in the foregoing step is added to the head end of the second video network address, so that the video network address of the same ethernet as the local video network terminal or the video network addresses of other ethernet introduced by the same ethernet as the local video network terminal can be obtained.

And 514, verifying the third video network address by adopting a second preset threshold, and converting the verified third video network address into a target video network address with the total number of digits reaching the second preset threshold.

In this step, the second predetermined threshold is the total number of digits of the view network address, for example, 64-bit view network address, and the second predetermined threshold is 20.

The method comprises the following steps: judging whether the total number of digits of the third video network address reaches a second preset threshold value or not; if the total number of digits in the third video network address is equal to a second preset threshold value, taking the third video network address as a target video network address; if the total digit number in the third video network address is greater than a second preset threshold value, ending the process and displaying the access failure; and if the total number of digits in the third video network address is smaller than a second preset threshold value, adding at least one 0 to the total number of digits equal to the second preset threshold value after the third video network address to obtain the target video network address.

In this step, if the total number of digits in the third video network address is greater than the second preset threshold, it indicates that the simplified video network address acquired by the local video network terminal and the local video network address do not belong to the same ethernet, and thus the process is ended and the access failure is displayed. If the total digit number in the third video network address is smaller than the second preset threshold, it indicates that the simplified video network address acquired by the local video network terminal removes the ethernet number of all zeros in the end portion of the video network address of the target video network terminal, and therefore at least 10 needs to be added after the third video network address until the total digit number is equal to the second preset threshold, obviously, because the ethernet number of all zeros in the subsequent portion is removed and is an integer multiple of the first preset threshold, the number of 0 added should also be an integer multiple of the first preset threshold.

Optionally, before step 512, further comprising: acquiring the number M of the address levels of the video networking to which the local address belongs, the number N of the number segments in the first video networking address and the total number Q of the address levels of the video networking; if M + N-1> Q, ending the process and displaying access failure; if M + N-1 is less than or equal to Q, go to step 512.

In the step, if M + N-1> Q, it is indicated that a target video networking address hierarchy corresponding to the simplified video networking address has exceeded a current video networking total hierarchy, and there is no corresponding target video networking terminal in the current video networking, if the step of determining whether the number digit number of the field in the first video networking address does not reach a first preset threshold is continuously entered, the finally obtained target video networking address number digit number total exceeds a second preset threshold, and obviously, there is no corresponding address, and the access is still failed, so that the flow can be directly ended and the access failure is displayed at M + N-1> Q, and the subsequent steps are omitted.
