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.}, keywords = {}, pubstate = {published}, tppubtype = {article} }

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.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

In this paper, we present a method to optimize the reliability of a live stream using multiple paths. Compared to other approaches, our method does not rely on feedback to achieve the reliability and thus does not add delay for retransmission attempts. We use the diversity of multiple paths to compensate for the loss of capacity in individual paths. By using an FEC code to generate redundant data the transmission is more robust against fluctuations in capacity of single paths. We present an optimization problem to find a rate allocation for the paths that minimizes the interruptions of the stream. The performance is evaluated in an emulated network based on real-world measurements. The evaluation shows that the theoretical values can be achieved with a small margin. The optimized allocation of rates to the paths increases the reliability by up to 12%.With coding the reliability can be increased by up to 20%, depending on the code rate.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
