2. Vission 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 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 the present 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 there are 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 embodiment of the invention is provided, the video network server receives the scheduling request sent by the client and forwards the scheduling request to the message forwarding server according to the protocol of the video network, and the message forwarding server selects the corresponding service server according to the load balance and informs the video network server of the access address of the service server so that the client can access the service server through the video network server.
Referring to fig. 5, a block diagram of an embodiment of a service scheduling system of a video network according to the present invention is shown, where the system may be applied to a video network, and specifically may include:
avideo network server 10, amessage forwarding server 20 and a plurality of service servers 30; thevideo network server 10 stores ascheduling configuration file 40, and thescheduling configuration file 40 stores at least one first request type identifier and a service server identifier corresponding to the first request type identifier.
Specifically, thevideo network server 10 is configured to receive a scheduling request sent by theclient 40, where the scheduling request includes a second request type identifier; thevideo network server 10 is used for forwarding the scheduling request and the scheduling configuration file to themessage forwarding server 20; themessage forwarding server 20 is configured to match the second request type identifier with the first request type identifier through the scheduling configuration file, and determine a corresponding service server identifier, and at least one service server 30 corresponding to the service server identifier; themessage forwarding server 20 is configured to select a service server 30 with a load status meeting a preset condition from at least one service server 30, and notify the access address of the service server 30 to thevideo network server 10, so that theclient 40 can access the service server 30 through thevideo network server 10.
In the embodiment of the present invention, the video networking system may provide multiple service services, including conference scheduling, conference monitoring, conference management, and the like, each service is implemented by a corresponding service server 30, when the video networking service scheduling system is configured, different first request type identifiers may be set according to different service services, the first request type identifiers are used for distinguishing types of service requested by theclient 40, such as a conference scheduling type, a conference monitoring type, a conference management type, and the like, and meanwhile, for different service services, a corresponding number of service servers 30 may be correspondingly allocated for executing services.
Referring to fig. 5, a specific example is shown, wherein three service servers are configured for the conference management service: the system comprises abusiness server 1, a business server 2 and a business server 3, wherein two business servers are configured aiming at the conference monitoring business: each service server in the same service is configured with the same service server identifier, and the service server identifier may establish a corresponding relationship with the first request type identifier of the service, and when a system is developed, the corresponding relationship is written into a scheduling configuration file and stored in thevideo network server 10 for subsequent scheduling operation.
Further, in the embodiment of the present invention, theclient 40 may not directly contact themessage forwarding server 20, but thevideo network server 10 forwards the scheduling request of theclient 40 to themessage forwarding server 20 for execution, so that each user participating in the service may directly send the scheduling request to thevideo network server 10, and thevideo network server 10 may generally be a micro cloud server, and for the scheme that the client is directly connected to the message forwarding server, the processing request mode of thevideo network server 10 is to establish a parallel task for processing a plurality of requests, and the efficiency of processing the request is high, and the processing amount is large.
In addition, when thevideo network server 10 receives the scheduling request from theclient 40, it will forward the scheduling request to themessage forwarding server 20 together with the scheduling configuration file, and if the scheduling configuration file already exists in themessage forwarding server 20, only the scheduling request may be forwarded, and themessage forwarding server 20 matches the second request type identifier in the scheduling request with the first request type identifier through the correspondence between the first request type identifier and the service server identifier stored in the scheduling configuration file, determines the corresponding service server identifier, and at least one service server 30 corresponding to the service server identifier, and further selecting a service server whose load status meets the preset condition through the load balancing principle, and informing the access address of the service server to the video network server so that the client can access the service server through the video network server.
