Introduction

Introduction

What Is Converged Network?

Converged Network is an implementation method of Software Define Network (SDN) and centrally manages network resources of VMware, KVM, and non-cloud physical machines.

Advantages

Converged Network has the following advantages:

  • Manages mappings between VLANs and VXLANs and allocates and releases port groups of heterogeneous resources.
  • Allows you to specify the IP and MAC addresses for creating a port during heterogeneous VM creation.
  • Continuously detects events such as VM migration and instructs the network module to process the events.

Application Scenarios

Converged Network centrally manages VMware, KVM, and non-cloud physical machine network resources. Figure 43-2 shows the application scenarios of Converged Network.

Workflow

  • Figure 43-4 shows the workflow of creating the local network mapping for VMs.
    Figure 43-4 Creating a local network mapping for VMs

    The workflow is described as follows:

    1. On the Converged Network management console, create a local network mapping with VMs. Converged Network calls the VPC API to obtain the VPC and its subnets and then assigns a VLAN for mapping a VMware network (port group) with the VPC network.
    2. Converged Network calls the API of the vCenter resource pool to create a port group.
    3. Converged Network saves the mapping between the VMware network and VPC network to the database.
  • Figure 43-5 shows the workflow of creating external ports for VMs.
    Figure 43-5 Creating external ports for VMs

    The workflow is described as follows:

    1. On the VMware ECS console, create a VM using the VPC network. VMware Service generates a VM creation task. During task execution, VMware Service calls the Converged Network API to create an external port.
    2. Converged Network searches for the VLAN ID mapping the VPC network, sets the external port label, and calls OpenStack Neutron to create an external port.
    3. When the VM is created, Converged Network updates the device ID and host ID of the port, instructs the AC to bind the VLAN and VXLAN on the network device through the southbound interface.
  • Figure 43-6 shows the workflow of creating the local network mapping for physical servers.
    Figure 43-6 Creating a local network mapping for physical machines

    The workflow is described as follows:

    1. On the Converged Network management console, create a local network mapping with a physical machine. Converged Network calls the VPC API to obtain the VPC and its subnets and then maps the physical machine's VLAN with the VPC network.
    2. Converged Network saves the mapping between the physical machine's VLAN and VPC network to the database.
  • Figure 43-7 shows the workflow of creating external ports for physical servers.
    Figure 43-7 Creating external ports for physical machines

The workflow is described as follows:

  1. On the Converged Network management console, apply for creating an external port for a physical machine.
  2. Converged Network searches for the VLAN ID mapping the VPC network, sets the external port label and host ID, and calls OpenStack Neutron to create an external port.
  3. Converged Network instructs the AC to create a binding relationship between the VLAN and VXLAN on the network device through a southbound interface.

Accessing and Using Converged Network

FusionCloud provides a web-based service management platform, that is, the ManageOne operation plane.

Users can use the ManageOne operation plane to access the cloud service. If you are a VDC administrator, VDC operator, or have the operation rights for the cloud service, you can directly log in to the ManageOne operation plane and choose this cloud service on the Product List or Console menu.
