For a better understanding of embodiments of the present invention, the following description of the video networking is presented to one skilled in the art:

the partial techniques applied by the video networking are as follows:

network technology (Network Technology)

The network technology innovation of the internet of vision improves on the traditional Ethernet (Ethernet) to face the potentially huge video traffic on the network. Unlike pure network Packet Switching (Packet Switching) or network circuit Switching (Circuit Switching), the technology of video networking employs Packet Switching to meet Streaming requirements. The video networking technology has the flexibility, simplicity and low price of packet switching, and simultaneously has the quality and the safety guarantee of circuit switching, thereby realizing the seamless connection of the whole network switching type virtual circuit and the data format.

Exchange technology (Switching Technology)

The video network adopts the two advantages of the asynchronization and the packet switching of the Ethernet, eliminates the Ethernet defect on the premise of full compatibility, has full-network end-to-end seamless connection, and is directly connected with the user terminal to directly bear the IP data packet. The user data does not need any format conversion in the whole network. The video networking is a higher-level form of Ethernet, is a real-time exchange platform, can realize real-time transmission of full-network large-scale high-definition video which cannot be realized by the current Internet, and pushes numerous network video applications to high definition and unification.

Server technology (Server Technology)

The server technology on the video networking and unified video platform is different from the server in the traditional sense, the streaming media transmission is based on connection-oriented basis, the data processing capability is irrelevant to the flow and the communication time, and a single network layer can contain signaling and data transmission. For voice and video services, the complexity of video networking and unified video platform streaming media processing is much simpler than that of data processing, and the efficiency is greatly improved by more than hundred times than that of a traditional server.

Accumulator technology (Storage Technology)

The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system for adapting to the ultra-large capacity and ultra-large flow media content, the program information in the server instruction is mapped to a specific hard disk space, the media content does not pass through the server any more, the media content is instantly and directly delivered to a user terminal, and the waiting time of the user is generally less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical motion of magnetic head seek of the hard disk, the resource consumption only accounts for 20% of the IP Internet of the same grade, but the concurrent flow which is 3 times greater than that of the traditional hard disk array is generated, and the comprehensive efficiency is improved by more than 10 times.

Network security technology (Network Security Technology)

The structural design of the video networking thoroughly structurally solves the network security problem puzzling the Internet by means of independent permission of each service, complete isolation of equipment and user data and the like, generally does not need antivirus programs or firewalls, eliminates attacks of hackers and viruses, and provides a structural carefree security network for users.

Service innovation technology (Service Innovation Technology)

The unified video platform fuses services with transmissions, whether a single user, private network users or a network aggregate, but automatically connects at a time. The user terminal, the set top box or the PC is directly connected to the unified video platform, so that various multimedia video services are obtained. The unified video platform adopts a menu type table allocation mode to replace the traditional complex application programming, and can realize complex application by using very few codes, thereby realizing 'infinite' new business innovation.

Networking of the video networking is as follows:

the video networking is a centrally controlled network structure, which may be of the tree network, star network, ring network, etc., but on the basis of this there is a need for a centralized control node in the network to control the whole network.

As shown in fig. 1, the view network is divided into an access network and a metropolitan area network.

The devices of the access network part can be mainly divided into 3 classes: node server, access switch, terminal (including various set-top boxes, code boards, memories, etc.). The node server is connected with an access switch, which can be connected with a plurality of terminals and can be connected with an Ethernet.

The node server is a node with a centralized control function in the access network, and can control the access switch and the terminal. The node server may be directly connected to the access switch or may be directly connected to the terminal.

Similarly, devices of the metropolitan area network portion can also be classified into 3 categories: metropolitan area server, node switch, node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is the node server of the access network part, namely the node server belongs to the access network part and also belongs to the metropolitan area network part.

The metropolitan area server is a node with centralized control function in the metropolitan area network, and can control a node switch and a node server. The metropolitan area server may be directly connected to the node switch or directly connected to the node server.

Thus, the whole video network is a hierarchical centralized control network structure, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star, ring and the like.

The access network part can be vividly called as a unified video platform (part in a dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform can be interconnected and intercommunicated through metropolitan area and wide area video networking.

2. View networking data 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 data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), 256 possibilities are at most provided, the second byte to the sixth byte are metropolitan area network addresses, and the seventh and eighth bytes are access network addresses;

the Source Address (SA) is also composed of 8 bytes (bytes), defined identically to the Destination Address (DA);

the reserved bytes consist of 2 bytes;

the payload portion has different lengths according to the types of the different datagrams, and is 64 bytes if it is various protocol packets, and 32+1024=1056 bytes if it is a unicast packet, and is of course not limited to the above 2 types;

The CRC consists of 4 bytes and its calculation method follows the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

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

The definition of label in this specification is similar to that of MPLS (Multi-Protocol Label Switch, multiprotocol label switching), and assuming that there are two connections between device a and device B, there are 2 labels for packets from device a to device B and 2 labels for packets from device B to device a. The label is split into label and label out, and assuming that the label (in label) of the packet entering the device a is 0x0000, the label (out label) of the packet when leaving the device a may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, that is, the address allocation and label allocation of the metropolitan area network are all led by the metropolitan area server, the node switch and the node server are all passively executed, which is different from the label allocation of the MPLS, which is the result of mutual negotiation between the switch and the server.

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

DA

SA

Reserved

label (Label)

Payload

CRC

I.e. Destination Address (DA), source Address (SA), reserved bytes (Reserved), labels, payload (PDU), CRC. Wherein the format of the tag may be defined with reference to the following: the tag is 32 bits, with the high 16bit reservation, with only the low 16bit, and its position is between the reserved bytes and payload of the packet.

Referring to fig. 5, a flowchart illustrating steps of a method for data processing according to an embodiment of the present invention may specifically include the following steps:

step 501, responding to user operation, generating a first state acquisition request for routing equipment in the video network, and sending the first state acquisition request to a network management server;

the first state obtaining request may be generated by the terminal device, and is used for obtaining a request of port state information of the routing device in the internet of view, for example, the PC side may generate and send an obtaining request of port state information of the routing device in the internet of view.

As an example, the network management server may be a network management server of the internet of view, which may have a network management private protocol snmp, for example, the network management server of the internet of view may be a snmp protocol module, may have a network management protocol modified with a public snmp protocol (simple network management protocol) (i.e., a network management private protocol snmp), and the network management private protocol snmp may include functions such as get acquisition, set setting, walk acquisition list, etc.

In the process of controlling the routing equipment in the video network, a user can operate through a PC end, generate an acquisition request of port state information for the routing equipment in the video network, and send the acquisition request to a video network management server so as to send the acquisition request to the routing equipment in the video network by adopting the video network management server.

In practical application, when a user performs port allocation for an established communication tunnel through a PC end, the user needs to acquire the port occupation condition of the user from a remote device (i.e. a routing device in the internet of view), and the user can send a request through the PC end to acquire port information of the remote device.

In an example, a request to obtain port information may be sent by the PC on the internet side for a third party route (i.e. a routing device located in the internet of view) for port allocation, then the request may be sent by the IP server to a snmp protocol module (i.e. a network management server), and the request may be sent by a transparent sdk (an internet of view transmission module) to the third party route located in the internet of view via the internet of view server.

Step 502, receiving bitmap data returned by the network management server for the first state acquisition request;

The bitmap data may be obtained by the routing device for the data returned by the first state acquisition request, and the network management server may send the bitmap data to the terminal device (such as a PC end).

The network management server of the internet of view can receive data (such as bitmap data) returned by the routing device for the first state acquisition request, and can send the bitmap data to the PC end, for example, the network management server of the internet of view can acquire the bitmap data from the remote device by adopting the get acquisition function of the network management private protocol snmp, such as 00:00:01: 01 ….

Step 503, generating port state information for the routing device according to the bitmap data;

the port state information may be port state information for a vlan port in the routing device.

After the bitmap data is received, the bitmap data can be analyzed through the terminal equipment (such as a PC end), so that port state information aiming at vlan ports in the routing equipment can be obtained.

And step 504, visualizing the port state information.

After the port state information is obtained, the port state information can be visualized, and then a number which can be identified by a user can be obtained, so that the user can obtain the port state information of the vlan port in the routing equipment.

For example, the display may be performed through a page of the terminal device (such as a PC end), so that a user may learn that one or more ports in the routing device are occupied.

The invention is illustrated below in connection with fig. 6:

the remote device (i.e. the routing device) located in the internet of view may have data stored in a bitmap manner, where the data may include information about the occupation of the ports in the remote device, and the remote device may send the data to the internet of view server through the transparent transmission sdk (the internet of view transmission module) in the internet of view, and then the internet of view server may send the data to the snmp protocol module (i.e. the network management server) through the transparent transmission sdk in the internet of view, and may further send the data to the PC, and may parse the data stored in the bitmap manner by adopting java, so as to obtain a number that may be identified by the user, so as to perform visualization.

Referring to fig. 7, a flowchart illustrating steps of another method for data processing according to an embodiment of the present invention may specifically include the following steps:

step 701, responding to user operation, generating a first state acquisition request for routing equipment in the video network, and sending the first state acquisition request to a network management server;

Step 702, receiving bitmap data returned by the network management server for the first state acquisition request;

the network management server of the internet of view can receive data (such as bitmap data) returned by the routing device for the first state acquisition request, and can send the bitmap data to the PC end, for example, the network management server of the internet of view can acquire the bitmap data from the remote device by adopting the get acquisition function of the network management private protocol snmp.

In an example, bitmap data, such as 00:00:11 …, may be obtained from a third party router (such as a third party customized private router device) located in the internet of view, where each byte may be composed of 8 binary bits, and 512 bytes of data in the bitmap data may correspond to 4096 vlan port data of the router device.

Step 703, determining a target port serial number for the routing device by using the bitmap data;

the port number may be a number of a vlan port in the routing device, and the target port number may be a port number set for a vlan port state in the routing device, for example, a port number set in which a vlan port state in the routing device is an occupied state.

After the bitmap data is received, the bitmap data can be analyzed through the terminal equipment (such as a PC end), so that a port sequence number set aiming at a vlan port state in the routing equipment can be obtained and used as a target port sequence number aiming at the routing equipment.

In an embodiment of the present invention, step 703 may include the following sub-steps:

a substep 11 of determining, for each character in the bitmap data, a bit sequence number of a target bit; wherein the target bit is a bit in a non-null state;

wherein the bit may be a bit of a character in the bitmap data, the bit may represent that the corresponding element state is present or absent, for example, a value of the bit is represented by 0 or 1; the target bit may be a bit in a non-null state.

After receiving the bitmap data, characters in the bitmap data may be traversed, and for each character, a bit sequence number of a bit in a non-null state may be determined, and thus may be used as a bit sequence number of a target bit.

For example, for one character 00:00:11 of bitmap data, where 0 may represent an idle state, 1 may represent a non-idle state, and in order to obtain port information that a vlan port state in a routing device is an occupied state, a bit in the non-idle state may be used as a target bit, that is, 1 in 00:00:11 is used as a target bit.

In the process of traversing characters, when traversing to ':', the next digit can be continuously traversed, and the bit sequence number i of the first 1 bit (target bit) can be specifically represented in the following way for one character 00:00:11 of bitmap data:

i=6, indicating that the count from 0 (":" also counts), bit 1 is traversed to bit 7.

A sub-step 12 of generating a target array by adopting the bit sequence number;

the target array may be an array for target bits, and may be used for performing bit and operation and binary conversion.

After determining the bit sequence number of the target bit, the bit sequence number may be used to generate a target array for the target bit for subsequent bit and operation and binary conversion.

In an embodiment of the present invention, the sub-step 12 may comprise the following sub-steps:

a substep 121, obtaining high-low weight information;

the high-low weight information may be a high-low weight for an array, for example, a byte array occupying four bytes, and may be set to 8, 4,2, and 1 from high to low, i.e., the weight of the highest bit may be 2=8, and then may be 2=4, 2=2, and 2=1 in sequence.

In practical application, the character can be converted into a four-bit array aiming at one acquired character data, and the four-bit array can be divided into high and low bits, so that the high and low bit weight information aiming at the four-bit array can be obtained.

A sub-step 122 of generating an intermediate value by using the bit sequence number;

wherein intermediate values may be used for bit and operation and binary conversion.

After determining the bit sequence number of the target bit, the bit sequence number may be used to generate an intermediate value for performing bit and operation and binary conversion, for example, the intermediate value c may be obtained according to the bit sequence number i, and specifically may be generated as follows:

Char c＝hex.charAt(i)；

Wherein hex is the acquired bitmap data 00:00:11, and the intermediate value c=1 can be obtained according to the bit sequence number i=6.

And step 123, combining the intermediate numerical value and the high-low weight information to generate a target array.

After the high-low weight information and the intermediate value for the array are acquired, the intermediate value and the high-low weight information can be combined to generate a target array for subsequent bit and operation and binary conversion.

And step 13, generating a target port serial number for the routing equipment by adopting the target array.

After the target array is generated, bit and operation and binary conversion can be performed by using the target array, so that a port sequence number set aiming at a vlan port state in the routing device can be obtained, for example, the port sequence number set can be used as a target port sequence number aiming at the routing device, for example, the port sequence number set can be subjected to operation (bit and operation), the binary conversion is performed into 16 binary, then the 16 binary is converted into 10 binary, and further, a numerical value which can be recognized by a user can be obtained.

In an example, for a target array, according to the high-low weight information (e.g., 8, 4, 2, 1 from high to low) of the array, any four binary numbers can be converted into corresponding decimal values through binary conversion, and when traversing from high to low to each bit with value of 1, the values which can be identified by the user can be obtained.

In yet another example, as shown in fig. 8, for one byte 00:00:11 in the acquired bitmap data, each number in the byte may be traversed, where j=4 (the current number of numbers) may be recorded when traversing to the first bit of 1, that is, when traversing to the first bit of 1, 4 numbers have been traversed, and the int value of the bitmap data may be converted into a byte array, and the bit position and the binary conversion may be performed, and specifically, the binary conversion calculation may be performed in the following manner:

int kk＝(c&0×8)>>3；

int kk1＝(c&0×4)>>2；

int kk2＝(c&0×2)>>1；

int kk3＝(c&0×1)；

when the kk value is 1, the calculation formula may be j×4+1; when the kk1 value is 1, the calculation formula can be corresponding to j+4+2; when the kk2 value is 1, the calculation formula can be j×4+3; when the kk3 value is 1, the calculation formula may be j×4+4.

For example, for 00:00:11, through binary conversion calculation, when c=1, j=4, kk:0, kk1:0, kk2:0, kk3:1 can be calculated, and then when kk3=1, a corresponding calculation formula j+4 can be adopted to obtain that the first element value of the port sequence number set (i.e. the target port sequence number) is 20, which indicates that the number 20 vlan port is in an occupied state.

As an example, in parsing bitmap data, a new set may be created for bitmap data of 512 bytes, the new set may be 4096 in size, and an initial subscript of the new set may be set to y=0, which may be specifically expressed as follows:

if(kk3＝＝1)；

uu[y++]＝kk3*j*4+4；

uu：{20,0,0,0,0,0,0,0,0,0,+4086more}，y＝1，kk3＝1

Wherein uu is a new set, y is a subscript recorded when a port occupies, and each time a port in an occupied state is traversed, the subscript y can be added with 1, for example, a number 20 vlan port is calculated to be in an occupied state through binary conversion, that is, the first element value of the new set is 20, the subscript y of the new set can be added with 1, that is, y=1, and 20 is stored in the new set, so that after traversing 512 characters of bitmap data, a new set (that is, a target port number) of a port sequence number of the vlan port in an occupied state can be obtained.

Step 704, setting the port state information corresponding to the target port serial number as an occupied state;

after determining the target port serial number, the port state information corresponding to the target port serial number may be set to an occupied state, so as to visualize the port in the occupied state in the routing device.

For example, when the port serial number set (i.e., the target port serial number) has a value of 10, 20, 30, the port state information corresponding to the value of 10, 20, 30 may be set to an occupied state, so as to visualize the port in the occupied state in the routing device, so that the user can learn that the port 10, 20, 30 in the routing device is in the occupied state.

Step 705, visualizing the port status information.

In the embodiment of the invention, the first state acquisition request for the routing equipment in the video network is generated by responding to the user operation and is sent to the network management server, then the bitmap data returned by the network management server for the first state acquisition request is received, the target port serial number for the routing equipment is determined by adopting the bitmap data, the port state information corresponding to the target port serial number is set as the occupied state, and the port state information is visualized, so that the port state information of the routing equipment in the video network is transmitted by adopting the bitmap data, the data transmission quantity is reduced, the transmission speed is improved, the bitmap data can be visualized, and the user can acquire the port information of the occupied state in the routing equipment conveniently.
