lightedge, a lightweight, ETSI-compliant MEC solution for 4G and 5G networks.
lightedge can provide Mobile Network Operators (MNOs) with a MEC platform that can immediately bring the advantages of edge computing to current 4G users, while enabling a seamless transition from the 4G towards a full 5G architecture.
lightedge is transparent to the existing components of a 4G network, therefore requiring zero modifications to the MNO’s environment. lightedge is designed to integrate seamlessly with standard ETSI NFV solutions like Open Source MANO (OSM).
Mapping the Evolution of Multi-access Edge Computing in Cellular Networks.
lightedge follows the bump in the wire architecture proposed by ETSI, thereby placing the MEC host between the RAN and the EPC of the 4G system to enable the interception of UE requests.
lightedge minimizes the changes to the MNO's existing infrastructure and can be seamlessly deployed between RAN and EPC as long as access to the S1AP and the S1 interfaces is provided.
Re-provisioning of MME pools is avoided by intercepting relevant UE attachment, detachment, and mobility events. lightedge can keep serving users even when handovers occur.

Frequently Asked Questions
-
Which eNodeB and EPC are supposrted by lightedge?
lightedge is in principle compatible with any standard compliant eNodeB and EPC. So far lightedge has been tested with several popular opensource 3GPP stacks including: srsLTE, Open5GS, and srsEPC.
-
Can you use lightedge with mulitple eNodeBs?
Yes, lightedge supports and has been tested with multiple eNodeBs at the same time.
-
Under which license is lightedge released?
lightedge is release under APACHE 2.0 license. Support for X2/S1 handover is available under a proprietary license.
-
I am an academic and I would like to cite lightedge. Which refence should use use?
Estefania Coronado, Zarrar Yousaf, and Roberto Riggio, "LightEdge: Mapping the Evolution of Multi-access Edge Computing in Cellular Networks", in IEEE Communications Magazine, to appear.
Demos
Assisted driving
Autonomous and connected vehicles are becoming the next piece of the 5G connectivity puzzle. Dealing with a diversified set of use cases, from manoeuvrer negotiation to infotainment, autonomous and connected vehicles call for a radically new approach to mobile networking.
This demo shows how features like lane tracking and object detection can be safely offloaded to the 5G network using lightedge without impairing their effectiveness.!
Thanks to Gabriel Cebrian-Marquez (University of Oviedo) for the support in realizing this demo.
