Connectivity: The Foundation of SD-WAN

Networks have evolved from T1’s and MPLS to SD-WAN using Internet. Multapplied Networks is your evolution to SD-WAN. Virtualize networks, aggregate bandwidth from multiple carrier last-mile circuits and manage the quality and performance of your customers’ connectivity.

Multi-site and Single-site
Secure Managed Networks

Multapplied Networks SD-WAN delivers highly reliable managed connectivity for your single-site or multi-site customers. Multiple circuits per site provides active/active sub-second failover, aggregated bandwidth and business continuity. Multapplied’s multi-site Private Wide Area Network (PWAN), allows you to connect multiple sites and route traffic privately, all within an encrypted tunnel.

Failover & Network Redundancy

Ensure customer services are online all the time. Multapplied SD-WAN gives you a fail-safe for your customers if an Internet connection degrades or drops. Multiple aggregated connections ensures customer data flows uninterrupted through remaining healthy circuits without dropping sessions.

In the Data Center, highly available Aggregation Servers hosting your customers sites ensure your customers never experience an outage due to infrastructure failures.  You can even configure customer profiles for Data Center redundancy.

Same-IP Failover

Each customer premise appliance maintains its own IP address in the event of a circuit failure. No more DNS round-robin time delays. With same-IP failover links go from cold to hot in under 300 milliseconds, ensuring applications always remain online. Our software can automatically move an appliance from one aggregator to another, should a primary aggregator fail. This automation significantly reduces customer downtime in the event of a systems failure compared to monitoring and moving services manually.

Same-IP Failover

Tunnel Bypass

Tunnel Bypass (Split Tunneling)

Tunnel bypass or “Split Tunneling” allows you to identify specific customer data traffic in a Classification Profile and send it directly out a defined internet circuit connected to the SD-WAN CPE device.  This defined data traffic exits this defined circuit  via its carriers Internet access and does not participate in the SD-WAN secure and prioritized tunnel.

Identifying the bypass traffic is done via the Classification Profile in a number of ways; Source or destination IP address, DSP Tag, Protocol, and port ID to name a few.

The circuit used to bypass this data traffic must also be configured as available within the Classification Profile.

Application Management

Mutapplied SD-WAN allows you to manage the behaviour of applications within individual customer networks.

Applications are managed using Quality of Service profiles to prioritize packets into Real-time, Interactive, Routine and Bulk classes. The QoS engine only allocates bandwidth to Real-time and Interactive classes when packets marked as such are present. Otherwise, the bandwidth is available for other classes of traffic. A default profile comes pre-installed. The chart below shows the settings in this default profile.

Bandwidth Adaptation

Bandwidth Adaptation continually monitors latency, jitter, and packet loss, automatically adjusting the bandwidth of a circuit to mitigate the effects of these problems.  This is beneficial in a variety of situations by automatically reducing bandwidth when specified thresholds are exceeded, providing a positive customer experience.

 

When a circuit comes online, a test is performed to determine its idle latency and jitter. These values become the “baseline” setting. When the circuit is idle, the baseline values are updated using the regular heartbeat packets sent between the CPE and Aggregator. This ensures both the CPE and Aggregator always have an accurate understanding of the leg’s normal latency. With packet loss detection enabled, the CPE and Aggregator will track the circuit’s loss rate and use this to determine issues with the leg.

Multi-site and Single-site Secure Managed Networks

Multapplied SD-WAN delivers highly reliable managed connections from your single-site or multi-site customers. Multiple circuits/sites give you active/active failover, shared and aggregated bandwidth and business continuity. Multapplied’s multi-site capability called Private Wide Area Network (PWAN) allows you: Network multiple sites securely, route traffic privately, and apply encryption.

Bandwidth Adaptation

Bandwidth Adaptation is a feature of Multapplied SD-WAN that automatically adjusts the bandwidth of a circuit to mitigate the effects of high latency, jitter, and packet loss to provide a positive customer experience. Bandwidth Adaptation can help in a variety of situations by reducing bandwidth speed and the latency and packet loss rate of the leg.

Multapplied SD-WAN continually monitors latency on each leg. When the circuit comes online, a test is performed to determine its idle latency and jitter. These values become the “baseline” latency and jitter. When the circuit is idle, the baseline values are updated using the regular heartbeat packets sent between the CPE and Aggregator. This ensures both the CPE and Aggregator always have an accurate understanding of the leg’s normal latency. With packet loss detection is enabled, the CPE and Aggregator will also track the circuit’s loss rate and use this to determine issues with the leg. The chart below shows how latency and throughput can change due to changes in available bandwidth on a leg.

Failover & Network Redundancy

Failover & Network Redundancy

Providing a fail safe for when an internet connection suddenly degrades or drops. Ensures services are kept online all the time.

Your data continues to flow through the remaining healthy links. Up to half the partner’s aggregators can fail without bonds going offline. In an environment with only two aggregators, it can be considered a type of mixed secondary with uniform assignment. In this configuration, aggregators must be kept at 50% or less CPU utilization, because their load will approximately double when the other aggregator in the pair fails.

Same-IP Failover

Same-IP Failover

Each appliance maintains its own IP address in the event of a failover. No more DNS round-robin time delays. With same-IP failover links go from cold to hot in under 300 milliseconds, ensuring applications always remain online. Our software can automatically move a bond from one aggregator to another if the bond’s primary aggregator fails. This significantly reduces downtime for a customer in the event of an aggregator failure compared to monitoring aggregators with an external system such as Nagios and moving bonds off of failed aggregators manually.

Tunnel Bypass

Tunnel Bypass

Tunnel bypass is a feature which allows customer traffic to be sent and received on a bonder directly via a leg, bypassing the tunnel and the aggregator.

Traffic bypassing the tunnel will SNAT using the leg’s IP address. As a result, return traffic will reach the bonder directly instead of via the aggregator.

For a bonder to send traffic that bypasses the tunnel, it must be classified using packet filters on the bond’s classification profile and the legs on the bond must be configured as available for tunnel bypass. Both of these settings can be accessed by clicking the “Tunnel Bypass” button located in the row of bond related buttons on the bond detail page.
