Problems solved by technology

[0006] However, generally, the server cluster that uses servers to forward complex data packets will not be too large, and the port aggregation using lacp will limit the number of server clusters to no more than 16 physical servers, so using two sets of stacked switches will cause more The stacking switch ports are wasted, especially the current 10 Gigabit port switches are expensive, and at the same time, the switches in the data center also need to occupy the space of the cabinet for placement, resulting in waste of cabinet space in the data center, resulting in higher investment in the data center

Embodiment 1

[0026] This embodiment shows a specific implementation of a method for configuring switch ports of a cloud platform when two physical switches are configured in a chain structure. Specifically, the first physical switch SW1 and the second physical switch SW2 form a chain, and more physical switches (not shown) can be connected according to actual needs.

[0027] The first physical switch SW1 is configured with northbound port S1, northbound port S3, southbound port S2, and southbound port S4 to form two pairs of northbound ports and two pairs of southbound ports, all of which are physical ports. Among them, all northbound ports are connected to upstream devices, and all southbound ports are connected to downstream devices. The number of southbound ports and northbound ports in the first physical machine SW1 can be up to 32 to directly connect 16 servers. Similarly, the second physical switch SW2 is configured with northbound port S5, northbound port S7, southbound port S6, an...

Embodiment 2

[0055] combined reference image 3 As shown, the main differences between this embodiment and Embodiment 1 are as follows. In this embodiment, the stack switch 10a includes a first physical switch SW1 , a second physical switch SW2 and a third physical switch SW3 in a chain. The configuration between the first physical switch SW1 and the second physical switch SW2 forms a stack link 13; the configuration between the second physical switch SW2 and the third physical switch SW3 forms a stack link 14; the configuration between the first physical switch SW1 and the third physical switch SW1 The physical switches SW3 are configured to form a stack link 15 . The first physical switch SW1 is respectively connected to two server clusters or three server clusters through an uplink and a downlink.

[0056] Preferably, the first physical switch SW1 , the second physical switch SW2 and the third physical switch SW3 can be directly connected to three independent server clusters (not show...

Abstract

The present invention provides a configuration method for cloud platform switch port aggregation, including: configuring at least two physical machine switches as a stacking switch forming at least one stacking link; dividing a stacking switch composed of several virtual ports and supporting north-south direction LACPDU Two groups of LACP link aggregation ports for message unicast, when LACPDU messages are unicast and responded between the physical machine switch and the server, modify the SYSTEM_ID field of the LACPDU message and response message to the local MAC address through the application program . In the present invention, there is no need to use two sets of physical stacking switches to complete the LACP protocol negotiation for load balancing of physical server clusters and link monitoring, which reduces the complexity of network deployment in the data center and saves the cabinet space of the data center, thereby significantly reducing It reduces the cost of network equipment in the data center, realizes the effects of load balancing and bandwidth expansion, and improves the scalability of the cloud platform.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a configuration method for port aggregation of a cloud platform switch. Background technique [0002] Port aggregation is to aggregate multiple ports together to form an aggregation group, so as to realize load sharing among member ports and provide higher connection reliability. Port aggregation can be divided into manual aggregation, dynamic lacp aggregation and static lacp aggregation. The basic configuration of ports in the same aggregation group should be consistent, that is, if a port is a trunk port, other ports are also configured as trunk ports; if the link type of this port is changed to an access port, the link types of other ports are also configured as Change to access port. [0003] In the cloud platform, server clusters constructed by multiple computing nodes are often used to realize the forwarding of complex inter-network message data, and usually rely ...
