What are the characteristics of Tungsten Fabric? How does it work? How to deploy? How to arrange it?... This is the confusion of many technical friends who are new to the TF community. In order to answer questions uniformly, we will sort out the contents related to the Tungsten Fabric architecture and release them on the official account one after another. Thank you for your follow, or you can leave us a message in the background, tell us the questions you most want to know, and the editor will help you find the answer.

As virtualization has become a key technology for providing public and private cloud services, network size issues have become increasingly apparent for virtualization technologies that have been widely used so far (for example, VMware using L2 networks, and Nova,Neutron or ML2 networks for OpenStack). Tungsten Fabric provides a highly scalable virtual network platform designed to support multi-tenant networks in the largest environment while supporting multiple coordinators.

Since few data center deployments are truly "green fields", it is almost always required to integrate workloads deployed on a new infrastructure with previously deployed workloads and networks. This article describes a set of deployment scenarios in which a new cloud infrastructure will be deployed and will need to coexist with the existing infrastructure.

Common use cases for Tungsten Fabric:

Implement highly scalable and flexible platform as a service and software as a service in OpenStack-managed data center

Virtual network using Kubernetes container management system, including Red Hat OpenShift

Allow new or existing virtualized environments running VMware vCenter to use Tungsten Fabric virtual networks between virtual machines

Connect the Tungsten Fabric virtual network to the physical network directly through the underlying network of the data center using BGP peering and network coverage and gateway routers.

These use cases can be deployed in any combination to meet the specific requirements of various deployment scenarios.

The main features of Tungsten Fabric are as follows:

The key features that support the main use cases are:

Virtual networks use encapsulation tunnels between virtual hosts

Plug-ins for open source coordinators for virtual machines and containers

Label-based Application-based Security Policy

Integration with VMware business process stack

Connect to an external network using BGP,SNAT and the underlying network

Because the same controller and forwarding components are used in each implementation, Tungsten Fabric provides a consistent interface to manage connections in all environments it supports, and is able to provide seamless connectivity between workloads managed by different coordinators, whether virtual machines or containers, as well as destinations to external networks.

Main features of Tungsten Fabric

Tungsten Fabric uses OpenStack and Kubernetes coordinators to manage and implement virtual networks in a cloud environment. Tungsten Fabric uses overlay networks between vRouters running on each host. Based on mature and standard network technologies, it now supports the wide area network of the world's major service providers, but is re-used for virtualized workloads and cloud automation in data centers, ranging from large enterprise data centers to smaller telecom companies POPs. It provides a number of enhancements to the native network implementation of the coordinator, including:

Highly scalable multi-tenant network

Multi-tenant IP address management

DHCP,ARP proxy to avoid flooding to the network

Efficient edge replication of broadcast and multicast traffic

Local, DNS resolution per tenant

Distributed Firewall with access Control list

Application-based security policy

Distributed load balancing across hosts

Network address translation (1:1 floating IP and distributed SNAT)

Use service links for virtual network functions

IPv4 and IPv6 dual stack support

BGP is peer to gateway router.

BGP as a Service (BGPaaS), used to assign routes between privately managed customer networks and service provider networks
