Deployment options with nacXwan SD-WAN as a Service

The technical architecture of the nacXwan solution includes three elements:

  • The CPE
  • The Concentrator (if necessary)
  • The Network Manager

The whole orchestration of the SD-WAN Infrastructure is carried out through the cloud-based nacXwan Network Manager regardless the deployed architecture at the customer’s, the number of nodes and type of WAN-link.

A first VPN connection for management purposes (Management nTS VPN) is established between the Network Manager and all CPEs and hubs in the park. This administrative VPN allows Network operators to distribute the configurations to the managed CPEs, as well as to collect all the data for statistics and alarms.

A classic example of an SD-WAN infrastructure

The CPEs (notably routers or VPN Concentrators) are installed at the clients’ premises. In this example the customer has different branch offices, each with a local network, based on either a physical or virtualised CPE. All routers are connected to each other through the nTS VPN (nacXwan Tunneling System) as well as the Network Operator, who can manage the whole installation through cloud-based Network Manager.

The preferred option for geographically distributed organisations

The example below shows the use of a CPE as a hub, which is typical for organisations with numerous branches. In this case, the hub grants to the branch offices protected access to the data center, usually hosted in the main office. Via nTS VPN, the Network Operator can access both the CPE at the main office and the single routers in each branch and manage all settings through the cloud-based Network Manager.

Smart-Workers or remote users can connect with their VPN client to either the local branch CPE or the hub. The Network Operator can customize this option according to his customer’s needs.

03.

Modern cloud-based SD-WAN environments

This architecture allows to host a virtualised VPN router / hub on a cloud plattform like Amazon AWS, Azure or Google or on a private cloud . nacXwan CPS can be deployed in virtual environments such as VMware, KVM, OpenStack, Hyper-V and many others. As for all other SD-WAN infrastructures, the Network Operator has a direct access to the whole deployed fleet and can monitor the link status as well as bandwidth consumption per application through the Network Manager, delivering accurate reporting and statistics.
