SOFTWARE DEFINED WAN FROM BRANCH
At a high-level, the image below shows what an SDN WAN looks like. Instead of bringing in an MPLS network into a branch location, customers can bring in two diverse internet connections. One is delivered on a cable modem with 50 megs of bandwidth, and the secondary a 4G router. In an SDN environment, a router is placed on the edge to provide a couple of features:
- Brings together the two connections
- Load balancing
- Proactive analysis of what is happening on that network
- Creates the ability to do a VPN for office Internet connectivity to connect branches to headquarters
- Because it is internet based, traffic that is destined for the internet can hop off right there
By application and by destination, this software can make intelligent routing decisions. Thus, if you have traffic destined for Office 365, it will decide if the cable or the 4G path is best, based on who has the best peering and who is the closest. Voice and video can be prioritized whether is outgoing or incoming. You can create a quality of service policy on both sides giving you end to end performance control that you would expect. So yes, you can get the performance of an MPLS solution with an SDN WAN solution even though it’s over an internet connection. Internet service is readily available and very cost effective as opposed to MPLS environments. The graphic from Freewire illustrates the flow:
VOICE AND VIDEO ERROR CORRECTION ON DEMAND
The image below reflects data collected with some intentional testing. In this example environment, we see two internet sources with high latency detected on one of the links. Seeing this, the application reroutes the traffic across the secondary link, and it doesn’t skip a beat. As things change over time, the traffic comes back and becomes more normal, and switches back and forth across the two solutions. That’s a peek into the magic.
INTERNET WITH VPN CHALLENGE
Some folks have turned to Internet as a solution with VPN over the top of that. This solution does solve some of the bandwidth constraint problems, as you can bring in more internet access and have additional bandwidth and layer on VPN to securely get traffic from one location to another. The challenges are the inability to protect certain types of traffic over anything else when it is Internet based. Firewall, router, VPN configuration, branch heavy equipment, and configuration are also required. Still, the benefit is a low-cost high-bandwidth, albeit you can’t prioritize traffic over the top of it.
SDN CREATED HYBRID WAN
The industry is shifting towards software defined networking. It is also known by several other buzz words like just SDN or Hybrid WAN. SDN gives you the look and feel of what an MPLS solution brings to the table, with the ability to prioritize certain traffic over another. It’s configuration adjustment is more simplified than a traditional router switch. You can also bring significantly more bandwidth for about the same money you would spend on a traditional network. Here are the main benefits at a glance:
- Enterprise-grade Performance
- Rapid Branch Deployment
- Cost-Effective Delivery Model
SDN UNIFIED COMMUNICATION FEATURES
With voice or IP communications, the ability to prioritize traffic is important. An SDN router keeps calls up and functioning in the event of any congestion, even Internet-based congestion. The router will duplicate the voice traffic and keep a secondary stream ready to go, so if it degrades while flowing on the primary connection, it will instantaneously flow over to the secondary connection and keep the call alive.
- Application Recognition and Quality of Service Policy
- Dynamic Application Steering
- On Demand Link Conditioning
SDN CLOUD DRIVEN POLICY EASY DEPLOYMENT
One of the other challenges in the industry with firewalled and traditional environments is the difficulty in creating the configuration in the equipment. If you have ever unboxed a Cisco firewall and wanted to create a VPN tunnel, it is a very complex setup which might require outside resources and other heavy lifting. In an SDN, it’s more of a cloud driven application where these devices put out on the edge are configured in a portal with a simple configuration that is easy to manage and adjust real time performance.
SIMPLE MONITORING AND TROUBLESHOOTING FROM THE CLOUD
Because these solutions are driven from cloud interface, the administration of devices can be done anywhere and are simple enough that anyone can take a look and see how the network is performing. Below is another image from Freewire-VeloCloud Orchestrator.
Q: What happens if you have Internet connection on both links? A: Performance would suffer and I would recommend to look at two different diverse mediums where the chances of both having issues would be slim to none. Examples would be fiber Internet backed up with coax, a coax backed up with a DSL, or a DSL backed up with a 4G.
Q: Is there room for innovation with this technology? A: An SDN solution gives great flexibility in your organization to bump up Salesforce in priority over youtube during the end of the month and adjust it back during the beginning of the month. Its portal driven and simple to administer.
Q: What are some of the providers that CoreTelcom.com partners with? A: Freewire brings this in as an overlay to any service you have. They use a back end solution from VeloCloud and I would encourage you to visit their website to see how they explain how it works. Vonage now also has VeloCloud instances as well. There are other negotiations being finalized currently to offer more providers. Cisco and their iWan product do this type of concept.
Q: Do we know what bandwith cutoff point would be? A: The VeloCloud solution from Freewire scales up to a gig of throughput. The edges adjust as more bandwidth is added.
Q: How does OpenFlow differ from SDN? A: OpenFlow is the same technology that enables SDN at the core.
Q: From a hardware standpoint, is there much latency that’s introduced by the SD WAN controller? A: The performance is tied to the bandwidth. If you’re getting a tier-1 providers internet, you will have less latency than a tier-4.
Q: Is it accurate to say that SDN is a poor-man’s MPLS? Or do the other benefits really make it another flavor altogether? A: It can be considered an MPLS replacement.
Q: Does the VeloCloud solution support the generation of netflow records? A: Netflow is a way that Cisco routers and switches use to take a look at traffic flow. This information has to be interpreted by something like our VX solution. An SDN router inherently has the software to show you how traffic is being marked as a high-low priority without the information interpretation processing.
1Wire is delivering the WAN you needOur unique technology allows us to setup virtually any network situation with powerful features. You can build an entire network using our SD-WAN or integrate our SD-WAN onto your existing network to enhance underperforming aspects and cut costs.
High quality voice
Robust Internet Speeds
MPLS is a thing of the past with Private WAN over public links.Create private Wide Area Networks with encryption, NAT and Port-Forwarding capabilities. Our Encryption feature allows for three layers of encryption for site-to-site traffic over public connections, creating secure WANs for customers looking for an alternative to MPLS.
1Wire Quality of Service(QoS) for any ApplicationInconsistent bandwidth speeds and choppy VoIP are an everyday concern for businesses. Using 1Wire QoS lets you assign unlimited priority layers on a single link or inside 1Wire’s combined links. 1Wire’s QoS determines the performance of your link or combined links to carve out a reliable Pipe. Within this new reliable Pipe, you can assign unlimited priority layers for your critical applications such as VoIP, while Data flows free from any disturbances like jitter and latency.
QoS for everyone!With 1Wire, businesses are no longer required to pay heavy premiums for QoS – our system will manage the flow of traffic between sites so that your calls and video conferences remain crisp and clean.
End-to-End QoSYour business dependence on voice and video communications will grow overtime. So does the need for those apps to reach their destination. Get the peace of mind that their packets will make the trip free of any disturbances like jitter and latency.
Bonded Bandwidth for your applicationsAs you move more and more applications to the cloud, your demand for bandwidth increases: more users, more information, wider highway. With 1Wire, you can now combine FWA, DSLs, Cable, and virtually any other access connection from 1Wire or any other carrier. By combining your connections you introduce the sum-total aggregation of upload and download in both directions to your network. You can now have all the bandwidth you need and expand as you need too.
Use what you have and add more connections1Wires bandwidth stacking technology allows you to keep your existing ISP agreements. You can take advantage of using your backup conections as well and take advantage of new features such as Failover.
Scale your bandwidthPerfectly suited for businesses with slow connections due to poor line quality or who experience persistent outages. Adaptively increase network bandwidth by stacking on additional lines, so the network scales to meet your business needs at consistent speeds required.
Failover – say goodbye to downtime1Wire provides Internet Failover Service (IFS). This unique service allows any business to combine multiple internet connections from any carrier(s) to create reliable internet connectivity. If one Internet connection suddenly goes offline, traffic will continue to flow to its destination and no data will be lost. If the problem connection becomes active again, the system will automatically add it back to its pipeline. No special configurations or specialist required to make changes to your network. Keep what you have and back it up with another internet connection. It’s that simple. Chances are, you might never realize you had an offline link.
Same-IP FailoverWith 1Wire SD-WAN Service, the secret is in the system’s ability to maintain the gateway IP address and the Internet access. Because of this “secret sauce”, application sessions (phone calls, media streams, etc.) continue uninterrupted.
Per-packet balancingOn top of the IP Address remaining the same even when a connection fails, each application session (phone call, for example) is broken into packets which are sent over the network. If a connection goes offline, the system just re-routes the packets – meaning your session continues without interruption.
