Virtual local area network-based speed limiting method and system for cloud hosts

Abstract

The invention discloses a virtual local area network-based speed limiting method and a virtual local area network-based speed limiting system. A core switch is arranged in an elastic compute node network and is connected with a network switch. A gateway is configured for public cloud and private cloud respectively on the core switch; and a public cloud public network and each private cloud publicnetwork WLAN between the core switch and the network switch are connected through independent links. Each common server in a CloudEx network is respectively connected to the network switch through two lines, wherein one line is used for public network communication; the other line is used for private network communication. Each common server is respectively connected to the network switch throughat least two lines, wherein one line is used for public network communication and used for bearing the public cloud public network VLAN and all private cloud public networks VLAN, and the other line is used for private network communication; and the public cloud public network VLAN and each private cloud public network VLAN between the core switch and the network switch are communicated through mutually independent links respectively. The method and the system make a plurality of cloud hosts share the network bandwidth and realize network isolation between users.

Description

technical field [0001] The present invention relates to computer network technology, in particular to a method and system for limiting the speed of a cloud host based on a virtual local area network (VLAN, Virtual Local Area Network). Background technique [0002] Cloud host is an important part of cloud computing in infrastructure applications, and it is located at the bottom of the cloud computing industry chain pyramid. It is characterized by high reliability, security, high performance, rapid response capability, elastic computing platform, and multiple nodes are optional. [0003] Cloud hosting is a virtual server built on a general server through the CloudEx elastic computing platform. The elastic computing platform can define the computing power, memory size, storage space and network bandwidth of the cloud host according to the needs of users. [0004] The structure of the CloudEx elastic computing platform is as follows: figure 1 shown. The CloudEx elastic compu...

However, all cloud hosts 101 public networks are in the same broadcast domain. With the increasingly severe network security situation, network attacks become more frequent. If one cloud host 101 is attacked by hackers or the user uses monitoring software, it will cause other cloud hosts 101 The network data transmitted by the user is monitored
