Increase WAN Reliability with Automatic Failover

Organizations are increasingly dependent on their data networks; in many offices, everything grinds to a halt if the Internet connection goes down.  The problem is even more acute for businesses using cloud computing and digital voice that require a continuous Wide Area Network (WAN) connection.  A crashed router might be up and running again in seconds, however, if a digger accidentally cuts through a cable, it could be hours—or even days—before the connection is restored.  The way to ensure business continuity is to have a second 'redundant' link, using an alternative route, that will provide connectivity if the primary connection fails.

For a small business with only a broadband Internet connection over DSL or cable, it might be enough to have a fixed wireless link or a cellular wireless hotspot as alternative connections.  For an organization with a multi-site MPLS network, installing redundant links with managed automatic failover (which switches traffic to the secondary link without any interruption in service) is the best way to ensure continuity.  It means that there is no need for the IT staff to intervene in the event of a network outage.

If the primary MPLS connection is over Ethernet, the secondary connection might be a cheaper DSL or cable line.  The second connection can remain in stand-by mode, but it is more efficient to use MPLS to dynamically balance the load between the two links and improve performance when both are operational.  MPLS QoS functionality can ensure that mission-critical traffic is routed on the highest performance link at any given time.

Contact Scisbo to find out the best way to implement managed automatic failover and network redundancy at your sites.  You’ll gain peace of mind knowing that your network will continue to operate during WAN outages.

MPLS vs VPLS for Your Company Network

MPLS and VPLS are two alternative ways of setting up a cost-effective private network for companies with multiple sites.  Both ensure that any site on your network can send data to any other site without inadvertently allowing outsiders to access it.  Some service providers will offer both, while others may have networks better suited to one rather than the other—this makes it challenging to get a straight answer about what you need.

MPLS stands for Multi-Protocol Label Switching and is a managed service that creates dedicated, labeled paths across the service provider’s network that are used only for your company's traffic.  These paths will carry your IP traffic at layer 3 [1] between sites in a very flexible way [2].  A benefit of MPLS is that it can reach most sites and prioritize important traffic.

VPLS stands for Virtual Private LAN Service, sometimes called E-LAN; it connects the Ethernet in the LANs on your premises across the public network at layer 2, without being aware of the IP traffic that runs on it.  Your IT specialists will have to configure the IP network at layer 3 to make sure that your data goes where you want it to go and is prioritized to suit your requirements.

VPLS is preferable for companies with a strong IT department who want to keep as much control as possible in-house, either to save money or for the enhanced security of not sharing IP addresses with the service provider.  If your organization doesn't have the skills in-house to manage the IP network, then MPLS is probably the best choice for you.  At Scisbo, we’re able to offer both MPLS and VPLS and can give you unbiased advice about what will best suit your organization's needs.  Contact us to find out how to create the most cost-effective network for your business.

MPLS creates flexible networks for multi-site organizations - and you don't have to move all sites at once

If your company has multiple office locations over diverse geographical areas, you’ll benefit from having them connected by a private, secure network.  One advantage of a private secure network is that it allows staff to exchange data and access servers at other sites without the security risks associated with the Internet.  We recommend an MPLS (Multi-Protocol Label Switching) network which is flexible, scalable, secure and cost-effective.

To create an MPLS network with direct connections between your company’s office locations, each site only needs to have a broadband access connection.  The service provider creates the private, secure MPLS network on top of this, at Layer 3 see [1].  Your company network then uses the public network infrastructure—keeping costs low—while maintaining the data separate in a virtual private network (VPN) [2] that provides a secure and scalable solution.

With this approach you can connect sites to the company network in almost any location, even in rural areas.  If offices are relocated or new ones are opened, it’s simple to reconfigure the network to accommodate the new sites.

And if you have network contracts at different sites that expire at different times, they can be transferred to your new MPLS network in stages.  Scisbo can work with your existing network, adding each site into the new network as its contract comes up for renewal.

Traffic on the MPLS network can be prioritized, so critical application data, such as EPOS (Electronic Point of Sale), can be given top priority to make sure your customers aren't kept waiting.  If your company uses VoIP for its voice network, then voice can be given priority over data on the same network, saving on the cost of providing separate SIP trunks.

In short, an MPLS network—based on its flexibility, security, and cost savings—is an excellent way to manage your company’s voice and data.  To learn more about using MPLS at your organization, contact us.
