MPLS Networks – High Speed Multi-Site Networking


Connecting into one single core network, managed centrally by your provider, MPLS networks bring benefits of simplicity, control and significant cost savings for your business.


As the circuits connect into a central ‘cloud’ rather than to a specific site, the network is more flexible & resilient than using site-to-site leased lines or VPNs, which require expensive routers and configuration.


At Spitfire, we offer a complete MPLS Solution – delivering secure high-speed, centrally managed inter-site connectivity using a wide range of circuits.


To discuss MPLS networks with our expert engineers, please call 0800 319 6363 or contact us online.


Key benefits of Spitfire MPLS networks include:


  •  High-speed, fully managed & secure solution


  • Wide choice of circuit connectivity options


  • Centrally managed internet connection


  • Easy to manage and low cost


  • Ideal for VoIP and SIP Trunks


  • Network wide SLAs.


  • No expensive routers


  • Easily scaled up or down (add, move or remove sites or circuits)


MPLS Circuit Infrastructure


Spitfire MPLS allows customers to deploy a private managed data network linking multiple sites directly into Spitfire’s core network using a wide range of circuits, including:


  •  Fibre Ethernet


  •  Copper Ethernet


  •  SDSL M


  •  VDSL (Fibre Broadband)


  • ADSL2+ / ADSL Max

What is MPLS?


Multiprotocol Label Switching (MPLS) is a “routing protocol” used in high performance networks. It labels each packet with a virtual “label” which is then used to move packets from one network node to another.


How does it work?


A label is assigned to each packet based on destination. MPLS is currently the fastest protocol available as the forwarding decision is based on the label and not the full IP address lookup.


Spitfire provide our customers with MPLS networks which provide very high security while reducing overall cost of ownership – standard circuit routers are used on site, meaning expensive routers and firewalls are not needed, and nor is any complicated on site customer configuration and management.


Full MPLS without external Internet Access




In the above diagram, external Internet access is not included & could be provided by additional standard Internet circuits (of any type) at one or more sites.


Full MPLS with external Internet Access


In the diagram below the Hosted Firewall provides a managed, central Internet connection which all sites can access. There is full control over how the Internet bandwidth is used.

Hosted Firewall


An integrated Hosted Firewall service allows Spitfire to provide a centralised Internet connection, for all sites. The MPLS cloud allows all sites to link to each other in a full mesh, and when linked to the Hosted Firewall this provides external access to the Internet – having a single large connection to the Internet, through one firewall reduces the cost of Internet bandwidth, while improving reliability, speed and management control.


The Hosted Firewall service also includes a VPN Concentrator to allow secure VPN access from staff who aren’t connected to the MPLS network, so home or mobile workers can also access your network.
