Transport Bottlenecks of Edge Computing in 5G Networks
We consider bottlenecks of TCP throughput in scenarios with edge clouds and 5G cellular networks. By numerical examples from measurements in real networks, we show that edge clouds indeed improve throughput but that several, nonnegligiblebottlenecks remain. We therefore devise a concept where edge c...

| description | We consider bottlenecks of TCP throughput in scenarios with edge clouds and 5G cellular networks. By numerical examples from measurements in real networks, we show that edge clouds indeed improve throughput but that several, nonnegligiblebottlenecks remain. We therefore devise a concept where edge clouds connected directly to the radio access network can increase their transmission rates by relying on built in retransmissions (through quality of service features) and on the built in user fairness (through per-user buffers and scheduler policies). We then return to the numerical examples and show that our solution provides substantial gains and we conclude by identifying and discussing the remaining bottlenecks. |
