Problems solved by technology

However, there are certain problems in using VLAN. 1) It requires the support of the chunk port of the physical switch. The actual deployment is more complicated, and a switch that supports VLAN must be required. Only switches above layer 3 have this function.
2) Due to its protocol (IEEE802.1Q), the VALN identifier has only 12 digits, and the number of vlan ids is 4094, that is, a maximum of 4094 subnet tenants. It is not suitable for p

Abstract

The invention provides a network domain division method. Firstly n virtual network domains are obtained through division according to the tenant number requirement, and n virtual protocol stacks are also established and a tenant ID is correspondingly allocated for each virtual network domain; and then m physical interfaces are selected according to the number of the virtual network domains, virtual interfaces which can be generated by the m physical interfaces are correspondingly distributed to n virtual network interfaces through division and then the n virtual network interfaces are added to the virtual network domains. When the physical interfaces cannot meet the requirements of the tenants, the network domains can be divided in a more flexible mode without being limited by the fact of whether the switch supports VLAN; meanwhile, each tenant network domain uses its independent virtual protocol stack so that network communication of other domains is not influenced when the network of one domain has problems.

Description

technical field [0001] The invention relates to the field of network application delivery control, in particular to a method for dividing network domains in a cloud environment not limited to VLAN (Virtual Local Area Network), which belongs to the multi-tenant network technology. Background technique [0002] With the trend of cloud planning and virtualization intensifying, the concept of tenants is becoming more and more important. In the cloud environment, it is an essential function of network equipment to allocate appropriate network resources for each tenant, and different tenants cannot affect each other. . In the current load balancing network equipment, the network is divided by VLAN (Virtual Local Area Network, virtual local area network). Each user has a VLAN, and VLAN is used to isolate tenants. VLAN is also a relatively mature network technology. Each VLAN With its own ID, different VLANs represent different tenants and do not affect each other. However, there ...
