Topologies

Random Linear Network Coding (RLNC) makes coding across a wide variety of network topologies technically viable. Although RLNC does not require a forklift upgrade, its implications are potentially significant in all data transport and storage fields, affecting both infrastructure and applications.

A wide range of markets stand to benefit from RLNC, including content distribution, video and multimedia streaming, broadcasting, mobile and wireless communications, device and equipment manufacturing, and cloud storage.

Point to Point

Applicable Markets

RLNC provides better performance in: wireless (4G, VoLTE, small cell, back haul, satellite, WiFi), Content Distribution Networks (CDN), Ethernet, Internet Protocol or other data packet networks (IP), DSL, cable, Passive Optical (PON), TCP, Over-the-Top (OTT), set-top box, cloud services, Software Defined Networking (SDN), Network Functional Virtualization (NFV), real time video streaming and any delay sensitive, lossy cata communication links.

RLNC is a substitute for all current point-to-point coding schemes

Sample Performance Improvements
