A multitenant-aware dynamic host configuration protocol (dhcp) mechanism for cloud networking

A dynamic host configuration, tenant technology, applied in the direction of data exchange, network interconnection, data exchange network, etc. through path configuration, can solve problems such as not supporting LINUX namespace, overlapping networks without interoperability, and lack of scalability. , to solve interoperability problems and simplify the provision of DHCP services

Problems solved by technology

Also, lack of scalability when the number of tenants grows into the thousands
In addition, many traditional operating systems (for example, WINDOWS SERVER and traditional LINUX kernels before 2.6.32.xx) do not support LINUX namespaces
[0006] Furthermore, even when overlay encapsulation protocols are used for multi-tenancy support (e.g. Virtual Local Area Network (VLAN), Virtual Extensible LAN (VXLAN), Distributed Overlay Virtual Ethernet (DOVE), use Generic Routing Encapsulation (NVGRE), stateless transport Tunneling (STT), Generic Network Virtualization Encapsulation (GENEVE), etc.), there is also no interoperability between overlay networks
Therefore, such a system cannot provide the flexibility required for multi-tenancy support

Embodiment Construction

[0023] The technical features of the present invention relate generally to a Dynamic Host Configuration Protocol (DHCP) mechanism for cloud networking, and more particularly to a DHCP mechanism for multi-tenant cloud networking. More specifically, embodiments of the present invention provide systems and methods for implementing technical features such as a novel DHCP mechanism for multi-tenant cloud networking, which solves the problem of address isolation for different tenants in a more efficient manner than current systems . For example, in an embodiment of the DHCP mechanism, tenant-specific information is included in the DHCP packets used to scope the address space.

[0024] The advantage of the above technical solution for the embodiment of the DHCP mechanism is that it is backward compatible and will not have adverse effects on the currently implemented DHCP processing system. Furthermore, if no tenant-specific information is provided in the DHCP packet, DHCP processing...

Abstract

One approach includes providing support for multi-tenancy support on the DHCP protocol. The method includes receiving a Dynamic Host Configuration Protocol (DHCP) packet, inserting tenant-specific option information within the DHCP packet, and transmitting the DHCP packet with the tenant-specific option information.

Description

technical field [0001] The technical features of the present invention generally relate to a Dynamic Host Configuration Protocol (DHCP) mechanism for cloud networking, and more specifically relate to a DHCP mechanism for multi-tenant cloud networking. Background technique [0002] Multi-tenancy support is a fundamental requirement for cloud data center networking, which requires service isolation among different tenants. One type of service isolation is address isolation that provides overlapping addresses to different tenants. In current standards such as the Internet Engineering Task Force Network Virtualization Overlay (IETFNVO3) standard, a Virtual Network Identifier (VNID) is provided to support separation of virtual networks of different tenants in an overlay virtual network. Addressing and host configuration may be provided through the Dynamic Host Configuration Protocol (DHCP), which provides configuration parameters to the host. [0003] DHCP has two components, i...
