Virtual Networking Overview

Metacloud Networking is a standalone service that deploys several processes across a number of nodes. The Networking processes work together and also interact with Metacloud services. This topic discusses supported virtual networking resources, refer to Using Network Resources for information about managing your hardware configuration.

Supported Networking Use Cases

Metacloud Networking supports the following network configurations:

Note
Refer to the Networking diagram below. The numbers associated with the use cases in this list refer to the numbered pathways in the diagram.

  • Two VMs communicating on the same network in the same project over static IPs(1) VM1 communicates to VM2 through the switching fabric on the network.
  • Two VMs communicating on different networks in the same project over static IPs(2) Communication between VM1 and VM2 passes through the switching fabric to the ASR on the network.
  • Two VMs communicating over floating IPs(3) Communication between VM1 and VM2 passes through one switching fabric to the ASR and then to the internal network gateway before passing through the second switching fabric to VM2.
  • Multiple VMs communicating to the Internet(4) VMs communicate through the switching fabric and the ASRs on the network through the gateway to access the Internet.
  • Multiple VMs receiving traffic from the Internet(5) Traffic from the Internet passes through the gateway to the ASRs and switching fabric down to the VMs.
  • Two VMs in different projects communicating over static IPs—VM1 communicates to VM2 through the switching fabric located in the shared project network.
  • One VM communicating on multiple networks—VMs communicate through the switching fabric and the ASRs on the physical network.
  • Create a DMZ or inside network configuration for public/private network isolation—VMs communicate on the same network through the switching fabric and ASRs.
