Eliminate Packet Loss and Downtime with Multapplied SD-WAN –
Reliable, high performance connectivity is critical to your business. You need networking solutions that are easy to deploy, cost-effective and capable of delivering performance, flexibility and continuity under all circumstances. A solution that can help you eliminate packet loss, downtime, reduce disruptions and dropped connections is key. Multapplied SD-WAN meets all these criteria.
Understanding the Architecture
Our unique approach to SD-WAN architecture is part of what makes us stand out and able to provide reliable, stable connections that don’t compromise performance. Unlike other vendors, you deploy as many SD-WAN core nodes in your data centers (we call them Aggregators, other companies call them Web or Cloud Gateways) as you need. This allows you to put Aggregators wherever you have enough customers, and also to create geo redundancy easily.
If it’s not evident already — these are your Core SD-WAN nodes. They are part of your infrastructure, you control them appling your IP addresses or making their IP addresses part of your infrastructure even if not directly in your infrastructure. You can use the API to extract key data into your billing, Network Management and Alerting systems.
You also get a Management Server. This is the configuration, command and control center of your SD-WAN environment. It is where you create separate secure spaces for each customer, where you create configurations for each customer site and where changes are made. All configs are automatically pushed into the Core and Edge nodes.
All our SD-WAN nodes (core or edge) run on standard x86 processors in bare metal, virtual or container environments. Our SD-WAN software can be deployed using Debian 9 and 10, Red Hat Enterprise Linux, SUSE Linux, KVM, VMware, Nspawn and Red Hat OpenShift.
Once the Aggregators and Management Server are installed, you can begin deploying WAN Edge or CPE devices.
Our software builds a virtual network between each WAN Edge device and the SD-WAN cloud, preferably using multiple internet connections at each customer site. The physical connections are used by the WAN Edge device for data transport. Our software manages the performance of these circuits and allows you to apply your IP addressing to the customer. If the customer needs more bandwidth or replaces a circuit connecting to the CPE device, the customer’s IP address will not change. The new circuit is simply added to the customer’s SD-WAN site profile and is put into service. This can be done live, while the customer is using the service and they will not notice any changes or lose any data sessions.
Data leaving the LAN enters the SD-WAN CPE, and the packets are distributed across the multiple physical connections. Upon arriving at the SD-WAN Aggregator in your network, the data packets are reassembled into a single data stream and sent to their final destination.
To leverage Multapplied’s SD-WAN solutions, you must have:
- IP addresses and the ability to route advertise them into the Internet
- The ability to host core SD-WAN nodes
- The ability to deploy and manage network infrastructure, including dynamic routing
- Tier 1 and 2 customer support capabilities
- Linux command line skills
Upgrading Your Capabilities
Multapplied’s SD-WAN solution doesn’t just help eliminate packet loss and downtime — it also expands your capabilities as an MSP to offer solutions customized to your customers’ needs.
Building Your SD-WAN Infrastructure
Let’s take a look at what it takes to build this SD-WAN infrastructure within your environment today.
What you have now:
- Data center (or centers)
- Firewall services
- Gateways to internet and cloud
- Core routing for internal infrastructure
- Hosted applications
What you need to add:
- Management Server (sometimes called an orchestrator) – Allows you to monitor, manage and configure your SD-WAN environment
- Aggregation Servers – Manages communications with customer sites; allows you to provide a multi-tenanted solution supporting multiple customers and sites per Aggregator. By design, multiple Aggregation Servers are required providing a natural High Availability configuration to the back end DC infrastructure. As you grow your customer base, simply add more Aggregation Servers as needed supporting a just in time deployment strategy to the core.
If you’re working with multiple data centers, your solution and needs will be the same, but look like the diagram above.
- Geo redundant fail over
- Up to N data centers
- Up to N data nodes
- Your gateways
- Your Infrastructure
- Your value add
- Connect Multiple sites nationally or globally
This lets you provide geo-redundant failover — if something happens in Data Center A, customers can be redirected to Data Center B with minimal disruption while their IP addresses converge from Data Center A to Data Center B.
If you opt to deploy customer Private Wide Area Networks (PWAN, or private, multi-site networks) using Multapplied’s capabilities, new tunnels and connections are built automatically as you add new Aggregators to customer spaces if you have selected the Managed Mesh PWAN option. You can also select the unmanaged option in which case you will need to define the routing paths manually. This can be desirable in some cases when specific data paths are required.
Demo: Eliminate Packet Loss and Downtime
We’ve talked a lot about the architecture and capabilities of our SD-WAN solution. But you don’t have to simply rely on our explanations — we’ve come up with a way to demonstrate exactly how well the Multapplied solution can eliminate packet loss and downtime.
Exploring the Dashboard
The Multapplied dashboard provides full transparency and control of all your connections to help you eliminate packet loss and downtime.
- CPU usage
- Quality of service
- Leg latency and state changes
- Packet loss
- Circuit status
- Tunnel traffic and latency
- Downtime prevented
- Quality of service (control bandwidth prioritization)
- Traffic class (control data type prioritization)
- Traffic flow (move large flows to bulk traffic)
- Bandwidth adaptation and optimization
The Mic Drop Moment
In the next clip, we’ll show you exactly what happens when connections fail. We’ll cut both of our fiber connections, one by one, forcing our data to failover to our backup LTE connection — while hosting a live webinar and running a large download.
Note that we can easily aggregate multiple LTE or other wireless data connections. In North America, LTE is cheap to own but relatively expensive to use, therefore many North American businesses will set up wireless as a failover circuit to manage cost. In some cases where wireless is the only possible access type or cost is not a factor, building your SD-WAN from multiple wireless circuits provides high reliability and flexibility. Our European Partners often use LTE as it is affordable and comes with true unlimited data plans.
As you can see, our effort to eliminate packet loss and downtime was a success. Using our dashboard, we can see the precise totals:
- 8935 packets transmitted, 8881 received
- Total loss of 54 packets
- 0.604% packet loss
But beyond the statistics, watching the video clip, the video and sound quality are never compromised as the traffic fails over from one connection to the next — and that’s the test that will mean everything to your customers.
