Private Network Overview

Private Network is a Layer 2 connectivity service that offers data center-wide (metro) connectivity between Leaseweb services.

Key Features:

• Automatic VLAN ID: Each customer who adds Private Network to their Leaseweb services automatically receives a single VLAN ID.
• Private IP Space Assignment: We offer automated Private IP space assignment via DHCP to simplify usage and prevent IP overlapping. DHCP can be enabled or disabled from the Customer Portal.

Connectivity: Private Network connects Leaseweb services and products within a single data center or across multiple data centers within a metro area. For example, a Leaseweb service in AMS-02 can connect with a service in AMS-01 using the same transport VLAN ID, remaining within the same Layer 2 domain.

Cost Efficiency: Traffic generated between Leaseweb services using Private Network is not measured and is free of charge within each metro area.

QinQ Support in Private Network

Private Network supports QinQ (IEEE 802.1ad), an Ethernet networking standard that allows private network traffic to be segmented into an additional 4000 sub-VLANs within the single Private Network VLAN provided by Leaseweb.

Key Features:

• Default Enablement: QinQ is enabled by default for all existing and new customers, free of charge.
• Customer Control: Customers have full control over the sub-VLANs and IP subnet assignment.

Important Note: QinQ VLAN traffic within the private network is segmented, not isolated.

Dedicated Servers (Shared racks)

Private Network connects two or more servers and/or other Leaseweb services (See Product availability).

Private Network is available for dedicated servers in shared racks in all data centers.

It is offered in below port speeds and connects each server with a single link to Private Network:

• 100 Mbps
• 1 Gbps
• 10 Gbps
• 25 Gbps (available in AMS-01, FRA-01, LON-01 and WDC-02 Data Centers)

Redundancy options

For customers requiring more resiliency in their environment, Leaseweb offers redundant Private Network for the following port speeds:

• 10 Gbps (2x 10Gbps in LACP, 802.3ad mode4)
  • This option provides 10 Gbps bandwidth with redundancy, using link aggregation and the LACP protocol for failover.
• 25 Gbps (2x 25Gps in LACP, 802.3ad mode4)
  • This option offers 25 Gbps bandwidth with redundancy, also using link aggregation and LACP.

Servers are connected with 2 (bonded) links to a redundant set of Private Network switches.
This setup ensures high availability by eliminating single points of failure in the Private Network.

Configuring Server-Side Bonding for Redundant Private Network

To make use of the redundant Private Network setup, you need to configure bonding on your server. Bonding, also known as link aggregation, combines multiple network interfaces into a single logical interface, called a bond.

Think of it as teaming up two network cables for your server. Even though your server has two physical connections, without bonding, it would only use one at a time.

Why is Bonding Necessary for Redundant Private Network?

• High availability: If one link or switch fails, the bond automatically switches to the other active link ensuring uninterrupted network connectivity. This is crucial for mission-critical applications and services that need to remain online.
• Load balancing: Some bonding modes distribute traffic across both links, which can improve network performance.

Without bonding, having two network interfaces connected to redundant switches wouldn’t provide true redundancy. Your server would only use one link, and if that link or switch failed, your server would lose connectivity.

Bonding Configuration:

Different bonding modes are available, each with pros and cons. Leaseweb uses LACP (802.3ad) for redundant Private Network. LACP is a dynamic link aggregation protocol that actively manages the bond, negotiates with the switches, and provides failover and load balancing capabilities.

How to set up and use Private Network for Dedicated Servers

Using the Leaseweb API or the Leaseweb Customer Portal, you can create a private network which connects two or more dedicated servers within the same data center or between interconnected data centers (in the same metro-area). For details, see the specifications below. Traffic sent between servers across the private network will not count towards your bandwidth costs.
For instructions, please refer to Private Network.

Different scenarios of using Private Network

This section describes possible scenarios using Private Network with Dedicated Servers (and Private Cloud).

Scenario	Graphical Representation
Database traffic and webserver application traffic are routed via the private network to ensure the traffic generated between the servers will be free of charge. Meanwhile, all servers remain connected to the public network. Information It is important to configure your applications accordingly otherwise the traffic will still use the public network
In this setup, the public uplinks of the application and database servers are disabled from the Leaseweb Customer Portal (by disabling the public switch port). Both servers will not have internet access and will only serve their services using the internal network.
In this setup, Public Cloud Instances or Private Cloud VM’s are connected to Dedicated servers through Private network. Both virtual and Dedicated servers have their public uplinks active. This setup ensures that database or backup traffic generated between Dedicated servers and VM’s is unmetered and free of charge. Information It is important to configure your applications accordingly otherwise the traffic will still use the public network.
Database traffic and webserver application traffic is routed via the private network to ensure the traffic generated between the servers will be free of charge. Meanwhile, all servers remain connected to the public network. Information It is important to configure your applications accordingly otherwise the traffic will still use the public network	In this setup, all the servers are disconnected from their primary public uplinks. A server is installed as a gateway. Such a scenario can be enlarged with software load balancers and firewalls. Information The public IPs of the different servers cannot be routed to this gateway box.
