Technology integration trends are turning wireless access networks into heterogeneous multipath environments.
The main driver is the proliferation of small cells and homespots (owned WiFi access points that are partially shared).
Homespots, for example, are projected to exceed 100 million by 2018, vastly overtaking commercial hotspots (Maravedis-Rethink forecasts).
Carriers are struggling to integrate WiFi and 3GPP technologies. Similar integration trends are well underway elsewhere; as service providers continue to combine satellite and 4G infrastructures and WISPs incorporate different generations of WiFi running on various frequencies.
Devices and wireless access infrastructure now support multiple streams at many levels. This is happening not only at lower layers with the proliferation of MIMO and multiple channel integration (channel bonding), but also at the transport layer, with increasing attention to multipath transport solutions such as MPTCP.
At the application layer, multipath is becoming the norm, as hosting ISPs grow their mesh overlays and multi-homing in datacenters and server farms becomes crucial for reliability and performance.
Although the efficiency and reliability gains of multipath communications is beyond any doubt, implementing multipath in heterogeneous networks turns out to be a complex problem.
In order to avoid performance losses compared with single-path solutions, operators and service providers need to dynamically combine load balancing with advanced packet scheduling and signaling.
Our core technology is a powerful multipath enabler as it removes the need for packet scheduling and greatly simplifies signaling.
Our algorithm yields up to 5x reductions in delays in a multipath configuration. When combined with MPTCP, our technology improves uptime and increases throughput by up to 20x over conventional MPTCP solutions in combined cellular, WiFi, and satellite networks.
Since our technology can operate at any network layer and can easily be integrated as software patches, it stands to transform not only wireless access but also hosting and storage services.
