Simplifying Deployment: The Promise of SMOAD Multipath Cellular Aggregation

Even a minute gap in connectivity can lead to a delay in productivity. Organisations are looking at multiple network connections to plug this gap and maintain seamless operations. Multipath Cellular Aggregation is the right solution to address this issue. It is a combination of multiple cellular connections offering reliable connections. Remote locations with poor connectivity or organisations with heavy bandwidth requirements experience a boost with Multipath Cellular Aggregation.

?

Various technologies, such as LTE-WAN (or LTE-broadband) aggregation, MPTCP, and LTE CA, are used to achieve Multiple Cellular Aggregation. In LTE-WAN aggregation solutions, like MPTCP proxy, LWA, and LET-U/LAA, bandwidths are combined. In LTE CA, multiple LTE channels are combined. MPTCP splits data and transmits it through LTE and WAN networks simultaneously.

Financial, healthcare, and retail verticals can choose Multiple Cellular Aggregation in SD-WAN due to its reliability and high-speed network connection.

?

If you want optimal performance, it is essential to implement Multiple Cellular Aggregation in SD-WAN with careful planning and configuration.

How do you choose the path for multipath cellular aggregation?

Using traffic flow, network conditions, and performance prerequisites, SD-WAN determines the path for multipath Cellular Aggregation. SD-WAN evaluates if the WAN appliance has active AutoVPN tunnels over both uplinks. Once the tunnels are established over the uplinks, the WAN appliance verifies if any dynamic path selection rules are determined. If the rules are specified, the WAN appliance assesses the tunnel to find out which satisfies the rules. For instance, if only one path satisfies the prerequisites then the traffic will be diverted in that VPN path.

?

Multiple cellular connections from various carriers can be used in multipath cellular aggregation. Different carriers provide high-speed and reliable network connections. SD-WAN determines which path the data packets should use. Another technique adopted by SD-WAN for determining path is load balancing. The traffic is distributed across multiple cellular connections to optimise the available bandwidth.

?

How do we handle network congestion in multipath cellular aggregation?

Dynamic routing traffic backed by policies and prioritising applications are strategies to tackle network congestion in multipath cellular aggregation. During network congestion, SD-WAN distributes traffic intelligently across multiple cellular connections to remove over-crowding and ensure seamless data flow. SD-WAN uses load-balancing techniques to optimise the application of available bandwidth across various cellular connections. This helps to remove network congestion and improve the network's overall performance.

?

SD-WAN solutions provide a centralised controller to engineer and manage network policies. The controller senses network congestion and adapts traffic routing in real time to prevent bottlenecks and ensure efficient data transmission. By dynamically selecting the optimal path for data packets depending on network conditions, the SD-WAN effectively manages network congestion in a multipath cellular aggregation setting.

?

Causes for congestion in SD-WAN multipath cellular aggregation

?

Bandwidth consumption:?Network congestion in multipath cellular aggregation can be caused by increased bandwidth consumption while offloading traffic from high-grade quality circuits to commodity internet circuits.?

?

Link disruption:?Any problem with transport links like MPLS, LTE or broadband can result in network congestion, interruption or poor performance. The disruption leads to packet loss, latency or poor connectivity, and network congestion.

?

Traffic routing issues:?To achieve optimal performance, SD-WAN dynamically routes traffic based on application priorities and policies. However, problems may arise even when precisely identifying and prioritising applications, resulting in less-than-optimal traffic routing and, hence, network congestion.

?

Controller Failures:?In SD-WAN, the centralised controller is used to manage network policies. The overall control and functionality of the SD-WAN deployment can lead to network congestion if the controller is overloaded, experiences failures or is threatened by misconfiguration.

?

Application identification:?SD-WAN can deliver optimal performance by accurately identifying critical applications and adhering to appropriate policies. A problem in identifying applications or a misconfiguration can result in poor performance and compromised user experience, which can lead to network congestion.

?

Network congestion can occur in a multipath cellular aggregation for many reasons. Some include stressed bandwidth consumption, controller failures, traffic routing issues, link disruption, and demanding application identification and prioritisation.
