Problems solved by technology

[0003] Device management and service management Each device is independently configured and managed, and the management complexity is high; and because the access device is much smaller in performance and table item specifications than the aggregation device, the access device is only divided into part of the virtual local area network (VirtualLocalAreaNetwork, VLAN) middle
Different access devices may be assigned to different VLANs. In this case, access devices cannot communicate at Layer 2, and can only communicate at Layer 3 through aggregation devices or higher-level devices.
At present, many applications have put forward requirements for the second layer. Obviously, this traditional hierarchical network cannot meet the requirements of the second layer.

Embodiment 1

[0048] see image 3 , image 3 It is a schematic flowchart of the path selection method in Embodiment 1 of the present invention. The specific steps are:

[0049] Step 301, any device in the networking obtains the topology information of each downstream access device, establishes a vertical combination aggregation group for each downstream access device, and adds the ports that the device can reach to each downstream access device to the In the vertical combination aggregation group established for each downstream access device.

[0050] In this step, a vertical combination aggregation group is established for each of the downstream access devices, including a vertical combination physical aggregation group and a vertical combination logical aggregation group. The ports contained in the vertical combination physical aggregation group are connected to the same access device directly connected to the device The ports in the vertical combination logical aggregation group are t...

Embodiment 2

[0062] In the specific embodiment of the present invention, the UNI includes ports other than the port connected between the aggregation device and the access device, and the port connected between the access device and the access device, such as the port connected to the server in the user network , the port connected to the switch or router in the user network, etc., here we collectively call it user equipment. In the specific embodiments of the present invention, for the convenience of description, the data message sent by the server is received through the UNI as an example, that is, the MAC address of the server is learned as an example, and the processing methods for other cases are the same.

[0063] Any device in the networking creates a UNI aggregation group for downstream access devices with aggregated UNIs. Any UNI aggregation group contains UNIs connected to the same server. There are multiple UNIs in the UNI aggregation group that do not belong to the same access ...

Embodiment 3

[0090] During the specific implementation of the present invention, when forwarding a unicast message, according to the forwarding of the destination MAC address of the unicast message, the MAC address may be learned from each port in the vertically combined logical aggregation group, or may be learned into the vertically combined physical aggregation group on each port. However, when forwarding broadcast packets, the locally established longitudinally combined logical aggregation group is not considered, and only the established vertically combined physical aggregation group is used.

[0091] see Figure 6, Figure 6 It is a schematic diagram of a packet forwarding process in Embodiment 3 of the present invention. The specific steps are:

[0092] Step 601, when any device in the networking needs to send a unicast message to a downstream device, it matches the destination MAC address of the unicast message with the locally learned MAC address, and if it matches, the longitu...

Abstract

The present application discloses a method for selecting a path. The method includes: any device in the networking obtains the topology information of each downstream access device in the networking, establishes a vertical combination aggregation group for each of the downstream access devices, and This device can reach the port of each downstream access device and join the vertical combination aggregation group established for the downstream access device; when receiving a unicast message that needs to be sent to any downstream access device, it The port in the vertical combination aggregation group established by the ingress device forwards the unicast message; if the vertical combination aggregation group includes multiple ports, a port is selected to forward the unicast message through a load balancing algorithm. Based on the same inventive concept, the present application also proposes a device capable of balancing the downlink traffic of each device.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for selecting a path. Background technique [0002] Commonly used networks generally have aggregation devices and access devices, and access devices may be deployed in multiple levels. In traditional networking, this hierarchical networking has the following disadvantages: [0003] Device management and service management Each device is independently configured and managed, and the management complexity is high; and because the access device is much smaller in performance and table item specifications than the aggregation device, the access device is only divided into part of the virtual local area network (VirtualLocalAreaNetwork, VLAN) middle. Different access devices may be assigned to different VLANs. In this case, access devices cannot communicate at Layer 2, but can only communicate at Layer 3 through aggregation devices or highe...
