Product Manual, TNSR 19.02
Learn the Basics
TNSR utilizes an optimized userspace data plane to forward packets at very high rates. On AWS, TNSR runs on a
customized VM instance and is managed by connecting to a command-line interface (CLI) over SSH.
There are many different network designs possible in AWS. This guide assumes a TNSR instance will sit in a VPC
connected to a private subnet and a public subnet (one which has access to the Internet).
This guide will show how to bring up a TNSR instance with 3 Elastic Network Adapter interfaces attached:
Management Interface
The primary network interface on the instance is used for management of the
TNSR instance. This is the interface reached via SSH to connect to the CLI on the TNSR instance.
Packets received on this interface will not be forwarded to another interface. The interface is used
for system functions such as DNS resolution and downloading software updates.
The management interface is required.
TNSR WAN/Internet Interface
The TNSR WAN interface is used by TNSR to connect to the Internet.
A WAN interface will have an
Elastic IP Address
assigned and it will be attached to a subnet that
has a route to an
Internet Gateway
in its
Route Table
.
TNSR LAN/Private Interface
The TNSR LAN interface connects TNSR to a private Subnet in the VPC.
The instances in the private subnet do not have their own
Elastic IP Addresses
and the
Route Table
for the subnet does not have a route to an
Internet Gateway
, but instead has a route to the
TNSR
LAN interface
.
Instances on the private subnet will use TNSR as their gateway to the Internet.
Each of the three network interfaces resides on a distinct subnet.
The examples in this guide use the following configuration:
Table 3: Example AWS Network Configuration
Item
Value
VPC Address Space
10.5.0.0/16
WAN Subnet
10.5.0.0/24
LAN Subnet
10.5.1.0/24
Management Subnet
10.5.2.0/24
In a real production VPC, the TNSR instance may have more than one WAN interface and/or more than one LAN
interface. The concepts covered in this guide can be extended to additional interfaces.
