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 networking, one of the core concepts of the embodiments of the present invention is provided, where the first conference management platform receives a speaker switching request sent by the first conference scheduling platform, and when it is determined that a conference area where a speaker to be switched is located in the speaker switching request is not the local area, determines a second conference management platform corresponding to the conference area, and sends the speaker switching request to the second conference management platform, and the second conference management platform executes an operation of switching speakers, so that an automatic speaker switching is realized, and a user does not need to perform switching after determining through other communication modes, thereby greatly improving the convenience of operation.
Referring to fig. 5a, a flowchart illustrating steps of an embodiment of a hierarchical conference scheduling method of the present invention, which may be applied in a video network, is shown.
In a hierarchical conference environment, one or more conference management platforms are deployed, each video networking server needs to be deployed in a partner with the conference management platform, then each conference is managed through the conference management platform, and partial conference data is transmitted through the conference management platform. The conference management platform is an application platform for conference reservation, audit and conference data management. Fig. 5b shows an exemplary network architecture diagram of a hierarchical conference environment in the present invention, in fig. 5b, taking a conference belonging to two video networks respectively as an example, a conference management platform is deployed corresponding to each video network server respectively, the first conference management platform manages the conference belonging to the first video network server, the second conference management platform manages the conference belonging to the second video network server, the first video network server and the second video network server are connected through a hierarchical conference control terminal, the first conference belonging to the first video network server and the second conference belonging to the second video network server are hierarchical conferences, and the video conferences are performed through the hierarchical conference control terminal. It should be noted that the first conference and the second conference given here are only examples, and may also include conferences belonging to more other video networking servers, and as long as the conference management platform is deployed in a partner manner, scheduling of the hierarchical conference may be implemented.
The hierarchical conference control terminal is a hardware terminal capable of communicating across a plurality of video networks. A hierarchical conference may be two (or more) conferences created separately within two (or more) video networks, the two (or more) conferences communicating through a hierarchical conference terminal. The participants of the conference refer to the roles of the entity terminals participating in the conference.
The method specifically comprises the following steps:
The conference scheduling platform is mainly realized by installing conference scheduling software, such as PAMIR software, in a computer and other terminals. The first conference management platform manages conferences (including the first conference) belonging to the first video networking server.
When the first conference and the second conference carry out video communication, if a user of the first conference wants to switch a speaker to a speaker in the second conference, an instruction for switching the speaker can be sent to the first conference scheduling platform through an operation device such as a remote controller, after the first conference scheduling platform receives the instruction for switching the speaker of the user, a speaker switching request is sent to the first conference management platform through the internet, and the first conference management platform can receive the speaker switching request sent by the first conference scheduling platform through the internet. The speaker may be a role of an entity terminal participating in the conference, such as a microphone, in the conference.
After receiving a speaker switching request through the internet, the first conference management platform acquires a conference area where a speaker to be switched is located in the speaker switching request, judges whether the conference area is the local area, and if the conference area is not the local area, inquires a pre-established corresponding relation between the conference area and the conference management platform to obtain a second conference management platform corresponding to the conference area. And the second conference management platform manages the conference belonging to the second video network server.
The first conference management platform sends the speaker switching request to the second conference management platform through the internet, and the second conference management platform controls the corresponding second conference scheduling platform to switch the speakers.
The second conference scheduling platform controls a second conference belonging to a second video networking server, the first video networking server is connected with the second video networking server through a hierarchical conference control terminal, and the first conference and the second conference carry out a video conference through the hierarchical conference control terminal. The first conference and the second conference are superior conferences and subordinate conferences, optionally, the first conference is an superior conference of the second conference, and the second conference is a subordinate conference of the first conference. The superior conference may be a conference of a main conference place, and the subordinate conference may be a conference of a branch conference place. When the first conference is a superior conference of the second conference, the first conference management platform is a superior management platform of the second conference management platform, which may also be referred to as a parent management platform.
And after receiving the speaker switching request sent by the first conference management platform through the Internet, the second conference management platform acquires the speaker to be switched in the speaker switching request, determines a second conference scheduling platform corresponding to the speaker to be switched, and generates a corresponding speaker switching instruction. The speaker to be switched may be a role of an entity terminal participating in the conference, such as a microphone.
And 505, the second conference management platform sends the first speaker switching instruction to the second conference scheduling platform, and the second conference scheduling platform switches speakers.
The second conference management platform sends the speaker switching instruction to the second conference scheduling platform through the internet, and the second conference scheduling platform controls the corresponding entity terminal (such as a microphone) to be opened, so that the speaker is switched to the speaker to be switched.
In the technical solution of this embodiment, after receiving, by the first conference management platform, a talker switching request sent by the corresponding first conference scheduling platform, if the conference area where the speaker to be switched in the speaker switching request is located is not the local area, determining a second conference management platform corresponding to the conference area, sending the speaker switching request to the second conference management platform, controlling the corresponding second conference scheduling platform by the second conference management platform to realize the switching of the speaker, therefore, when the users need to switch the speakers in the hierarchical conference, the users do not need to determine the switching through a communication mode except the hierarchical conference, the speakers can be automatically switched through the corresponding conference management platform, frequent operations among the users are reduced, the convenience of user operation is greatly improved, and the practicability and operability of the hierarchical conference are improved.
On the basis of the above embodiment, the method may further include:
when the first conference management platform determines that the conference area is the local area, determining a third conference scheduling platform corresponding to a speaker to be switched in the speaker switching request, and generating a second speaker switching instruction;
and the first conference management platform sends the second speaker switching instruction to the third conference dispatching platform so as to instruct the third conference dispatching platform to switch speakers.
When the first conference management platform determines that the conference area where the speaker to be switched is located is the local area, the first conference management platform can directly perform speaker switching, namely, the speaker to be switched in the speaker switching request is determined, a third conference scheduling platform corresponding to the speaker is determined, a second speaker switching instruction is generated and then sent to the third conference scheduling platform through the internet, the third conference scheduling platform switches the speaker, and automatic switching of the speaker in the conference of the local area is achieved.
