abstract = {Systems for assisted and autonomous driving increasingly depend on
information received and updated through wireless communication. But
wireless communication often faces performance degradation because of its
dynamic nature. Using multiple available communication channels, such as
WiFi, LTE or 5G New Radio, simultaneously can increase the throughput and
reliability, but also increases the dynamics of the system. MPTCP estimates
the channel capacity and latency and schedule packets accordingly. However,
in conditions with unstable channels MPTCP fails to fully utilize the
available capacity. In this paper, we propose the use of Network Coding to
efficiently utilize the available resources. We use a channel agnostic,
random scheduler to maximize the utilization of all available channels.
This prevents underestimations, but also produces a high number of packet
loss and duplicate transmissions. We use Network Coding to repair the
losses and reduce the overhead of redundant data. Our implementation of
this protocol is evaluated against MPTCP in an emulated multipath network
with time-varying path properties. The evaluation shows, that the proposed
protocol utilizes the channels efficiently even in unstable conditions. In
the evaluated dynamic network, the proposed protocol efficiently utilizes
94% of the available capacity, while MPTCP is below 80% due to
underestimation. While our protocol is not suitable for general purpose
traffic, it provides good performance for large file transfers in unstable
wireless multipath networks.},

abstract = {Software Defined Networking (SDN) and Network Function Virtualization (NFV) processed in Multi-access Edge Computing (MEC) cloud systems have been proposed as critical paradigms for achieving the low latency requirements of the tactile Internet. While virtual network functions (VNFs) allow greater flexibility compared to hardware based solutions, the VNF abstraction also introduces additional packet processing delays. In this paper, we investigate the practical feasibility of NFV with respect to the tactile Internet latency requirements. We develop, implement, and evaluate Chain bAsed Low latency VNF ImplemeNtation (CALVIN), a low-latency management framework for distributed Service Function Chains (SFCs). CALVIN classifies VNFs into elementary, basic, and advanced VNFs. CALVIN implements elementary and basic VNFs in the kernel space, while advanced VNFs are implemented in the user space. Throughout, CALVIN employs a distributed mapping with one VNF per Virtual Machine (VM) in a MEC system. Moreover, CALVIN avoids the metadata structure processing and batch processing of packets in the conventional Linux networking stack so as to achieve short per-packet latencies. Our rigorous measurements on off-the-shelf conventional networking and computing hardware demonstrate that CALVIN achieves round-trip times from a MEC ingress point via an elementary forwarding VNF and a MEC server to a MEC egress point on the order of 0.32~ms. Our measurements also indicate that MEC network coding and encryption are feasible for small 256 byte packets with an MEC latency budget of .35~ms; whereas, large 1400 byte packets can complete the network coding, but not the encryption within the 0.35~ms.},
