Highly Reliable Communication Using Multipath Slices with Alternating Transmission

The development of mobile networks with network-slicing technologies has facilitated the delivery of increasingly customized applications to customers in various business verticals. Network slicing technology has made it possible to tailor applications to meet specific and rigorous requirements. However, Ultra-Reliable Low-Latency Communications (URLLC) remain challenging due to deploying network slices over an unreliable physical substrate. Traditionally, reliability has been enhanced through multipath, but this approach is limited to delivering URLLC. To address this issue, we propose and evaluate a method based on P4 that utilizes slices to enable reliability using the Alternating Transmission (AT) technique without Packet Duplication (PD). Our approach guarantees slice reliability while saving bandwidth compared to existing state-of-the-art methods.
