Dynamic Path Selection
Lavelle Networks copyright ScaleAOn path selection provides an intelligent path control solution to provide best application experience to end user even in case of varying WAN characteristics of one or more transports.
ScaleAOn supports both automatic and intelligent dynamic path selection as well as policy governed path selection modes of operations. ScaleAOn path selection provides an intelligent path control solution that allows each application to dynamically switch the paths in real-time, in response to network conditions.
CloudPort devices constantly monitor the quality of each path, in terms of latency, jitters and packet loss in real time. ScaleAOn algorithms take these WAN attributes and the bandwidth capacity of the path as raw input to steer the outgoing traffic through the best path available for that traffic in a fashion to optimise end-user QoE.
Flowlet Based Load Balancing & per-packet load balancing (PPLB).
The Flow Let based load balancing moves a flow from a congested path to another path, based on the quality(latency, jitter, packet drop) and capacity characteristics of the flow. This type of load balancing adapts the nature of the flow to the characteristics of the path on which the flow is pinned. When the characteristics of the path changes, the flow is automatically pinned to a better path to provide the best path characteristics to that Flow Let. Used to avoid path congestion and for ensuring equal utilization for all paths to the same destination by aggregating the overall throughput of a singular flow across multiple PATHs. Packet order correction is done at the receiving end of the network.
If there are multiple WAN links whose metrics fall within the best Quality Score Band, then the application traffic is load balanced across all these WAN on a per packet by packet basis. The system does an automatic Packet Order Correction and Random Early Detection (RED) based automatic queue management (AQM) for the interface queue scheduler. This ensures the best quality of experience for the application traffic user. The algorithm automatically falls back to flow based Load balancing after detecting the performance degradation because of huge delays in packet reordering due to large delta of WAN characteristics (Latency, Packet Loss Rate, and Jitter) of multiple WAN links.
Bandwidth Aggregation
According to IDC, the "optimization of WAN bandwidth" and "consistent application security are the top two motivations for SD-WAN deployments.
ScaleAOn aggregates the bandwidth of different circuit types delivering resilience and throughput. ScaleAOn’s unique ability to aggregate traffic over multiple links, ensures our customers get the benefit of all the available bandwidth on site, all the time. With ScaleAOn Bandwidth Aggregation we ensure that business-critical unified communication application performance remains high
Bandwidth aggregation in ScaleAOn uses PPLB balancing to maximize the bandwidth utilization to ensure that chatty applications have the performance they need, without compromising the bandwidth of other applications.
