Embodiment 1

[0025] Embodiment 1 of the two-layer network data transmission method of the present invention, as figure 1 As shown, the method includes:

[0026] Step 101: configure a balance group for network nodes according to the network architecture to avoid broadcast storms, and a balance group includes one or more interfaces;

[0027] The network nodes mentioned in the present invention can be network access equipment, aggregation equipment or network core equipment. In order to better describe the content of the present invention, this paper introduces the following concept definitions:

[0028] Uplink interface: In the data center network structure, the interface that interacts with the upper-layer network nodes is the uplink interface of the network nodes at this layer.

[0029] Downlink interface: In the data center network structure, the interface that interacts with the lower-layer network nodes is the downlink interface of the network nodes at this layer.

[0030] In the pres...

Embodiment 2

[0040] Embodiment 2 of the two-layer network data transmission method of the present invention, as image 3 As shown, the method includes:

[0041] Step 301: Configure a balance group for network nodes according to the network architecture to avoid broadcast storms, and a balance group includes one or more interfaces;

[0042] The interfaces in the balanced group are all uplink interfaces for interacting with upper-layer network nodes or all are downlink interfaces for interacting with lower-layer network nodes.

[0043] Step 302: the network node receives the message from the receiving interface;

[0044] Step 303: the network node performs MAC processing according to the MAC (Media Access Control, Media Access Control) information in the message;

[0045] Specifically, as Figure 4 As shown, MAC processing includes:

[0046] Step 401: The network node queries the local MAC address table according to the MAC information carried in the message;

[0047] Step 402: If no ma...

Abstract

The invention relates to a two-layer network data transmission method and a network node. The method comprises that: a balance group is configured for the network node according to a network framework with avoidance of broadcast storm as the principle, and one balance group comprises one or multiple interfaces; the network node receives a message from a receiving interface; and the network node forwards the message to the interfaces of the balance groups apart from the ones in which the receiving interface is positioned. According to the method and the network node, the balance group is configured for the network node according to the network framework with avoidance of the broadcast storm as the principle, when the message is forwarded, the message is forwarded to all other interfaces apart from the ones in which the receiving interface is positioned according to the preset balance groups so that the broadcast storm can be effectively avoided.

Description

technical field [0001] The invention relates to network communication technology, more specifically, a two-layer network data transmission method and a network node. Background technique [0002] With the increasing application of the Internet, the application of data centers is also becoming more and more extensive. In relevant standard organizations, various technical standards related to data centers are also actively advancing. In order to achieve more convenient dynamic migration of virtual machines in the data center network, it is a basic requirement for building a data center to require the data center network to be a large Layer 2 network. [0003] In a Layer 2 network, in order to improve the reliability and robustness of network connections, there is usually redundancy on the networking so that traffic can be switched to the backup link in the event of a failure. However, the existence of redundant links leads to the natural existence of loops in the network, wh...
