MARCH - Multilink Architecture for Multiplay Services

Lividi has participated in several research projects since 2008 together with both national and international partners. In the Celtic MARCH project, which started in 2008, Lividi has developed multilink networking technology. Multilink technology allows a number of heterogeneous networks to be used concurrently, for improved robustness and performance.

As an example, a user with the need for moving around may join a video conference session utilizing both wired (e.g., Ehternet) and wireless (e.g., WiFi, 3G) networks concurrently. When disconnecting the wired network, WiFi and 3G allow the session to continue. Later, when moving out of WiFi coverage, multiple 3G network connections from different network operators provide session continuity while on the move. By utilizing several networks simultaneously the single point of failure represented by a single network link is avoided and performance is boosted by utilizing the full aggregated network capacity.

The MARCH project has successfully finished, with the final public workshop and evaluation taking place at Telenor, Oslo, Norway, in September 2011. An article from the final workshop has been published at the web pages for the Norwegian Research Council (in Norwegian only).

The Lividi multilink technology was also demonstrated publicly during the Spitsbergen Excavations 2010.
