Problems solved by technology

[0002] The structure mode of the two-layer network has the core layer and the access layer, and the operation is simple. The switch forwards the data packet according to the MAC address table, if there is any, it will be flooded, that is, the data packet will be broadcast to all ports. If the destination terminal receives When the response is given, the switch can add the MAC address to the address table. This is the process by which the switch establishes the MAC address. The network storm formed in the architecture is very large, which greatly limits the expansion of the scale of the layer 2 network. Therefore, the networking capability of the layer 2 network is very limited, so it is generally only used to build a small local area network
However, the management of the designated switch in the prior art is not mature, the data in the designated switch cannot be updated synchronously, and it is impossible to accurately determine whether the designated switch fails. When the designated switch fails, the designated switch cannot be replaced in time to perform relevant data Continue to process, resulting in too long data migration process and lower management efficiency of the Layer 2 network
[0005] Moreover, in the HINOC network, the broadband access rate is inseparable from the real-time transmission. When the HINOC network is operating at full capacity, it is worried that it will support 32 HMs to work at the same time, and services such as voice, video calls, and live video broadcasting have great impact on data transmission. The real-time requirements of the network are high, so it is imminent to improve the network performance

Embodiment 1

[0091] The above-mentioned sending-end switch receives the feedback information within a preset time, and the specific steps for data synchronization with the above-mentioned receiving-end switch are as follows:

[0092] A. Judgment step: the above-mentioned sending end switch receives the feedback information within a preset time, and judges whether the updated message data after the time stamp carried in the response message is complete according to the identification in the above-mentioned response message;

[0093] B. Confirmation step: If the updated message data after the time stamp carried in the above response message is incomplete, the above-mentioned sending-end switch sends confirmation information to the receiving-end switch; wherein, the above-mentioned confirmation information is used to notify the receiving-end Data updated after the above timestamp other than the data carried;

[0094] C. Sending step: the receiving end switch sends feedback information to the se...

Embodiment 2

[0097] The above-mentioned sending-end switch judges that the feedback information has not been received within the preset time, and the specific steps for determining that the receiving-end switch is invalid are as follows:

[0098] a. The switch at the sending end does not receive the above feedback information within the preset time, the switch at the sending end resends the Layer 3 network message to the switch at the receiving end;

[0099] b. When the number of times of resending request information exceeds a preset threshold and the sending-end switch does not receive the feedback information, the sending-end switch determines that the receiving-end switch is invalid;

[0100] For example, in order to ensure that the sending-end switch can detect the crash of the receiving-end switch and switch over in time, you can set the number of retransmission request information to exceed the retransmission upper limit, then the receiving-end switch is considered to be invalid, and...

Abstract

The invention discloses a packet transmission method and system based on a two-layer network. The method comprises: a sending end switch encapsulates a layer-two network packet to generate a three-layer network packet; Different sending priority levels are respectively set with different sending mode identifiers to distinguish, and the corresponding sending rules for the different sending mode identifiers are determined; according to the control flag bits of the different sending mode identifiers, the sending rules for the three-layer network packet transmission are selected , and send the Layer 3 network packet to the receiving end switch according to the sending rule; the receiving end switch decapsulates the Layer 3 network packet, responds to the Layer 3 network packet, and generates a feedback information, and send the feedback information to the sending end switch; the sending end switch judges whether the feedback information is received within a preset time. The method improves the efficiency of HINOC network management and meets the transmission requirements during data transmission.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a layer-2 network-based message transmission method and system. Background technique [0002] The structure mode of the two-layer network has the core layer and the access layer, and the operation is simple. The switch forwards the data packet according to the MAC address table, if there is any, it will be flooded, that is, the data packet will be broadcast to all ports. If the destination terminal receives When the response is given, the switch can add the MAC address to the address table. This is the process by which the switch establishes the MAC address. The network storm formed in the architecture is very large, which also largely limits the expansion of the scale of the Layer 2 network. Therefore, the networking capability of the Layer 2 network is very limited, so it is generally only used to build a small LAN. [0003] With the maturity of cloud data centers d...
