High-speed optical networks latency measurements in the microsecond timescale with software-based traffic injection
In many optical network scenarios, such as Storage Array Network (SAN) replication, keeping latency under control is cornerstone to provide a proper Quality of Service (QoS). Hence, measuring latencies in such optical networks becomes fundamental. However, for low distances, microseconds resolution...

Hence, measuring latencies in such optical networks becomes fundamental. However, for low distances, microseconds resolution is required, which, in turn, demands ad-hoc hardware implementation for the measurement device. Alternatively, a more cost-effective solution is that of software-based methods, but up to date they were not precise enough at 10 Gbit/s or above. In this paper, we analyze current high-performance packet engines, such as DPDK, and pinpoint the issues involved when it comes to measure latencies in high-speed optical networks. Based on these findings, we propose the use of a software-based solution to measure latency. Furthermore, we also propose an extension that serves to measure bandwidth as well, with the novel concept of convoy of packet trains. | ||

High-speed optical networks latency measurements in the microsecond timescale with software-based traffic injection |
| abstract |
In many optical network scenarios, such as Storage Array Network (SAN) replication, keeping latency under control is cornerstone to provide a proper Quality of Service (QoS). Hence, measuring latencies in such optical networks becomes fundamental. However, for low distances, microseconds resolution is required, which, in turn, demands ad-hoc hardware implementation for the measurement device. Alternatively, a more cost-effective solution is that of software-based methods, but up to date they were not precise enough at 10 Gbit/s or above. In this paper, we analyze current high-performance packet engines, such as DPDK, and pinpoint the issues involved when it comes to measure latencies in high-speed optical networks. Based on these findings, we propose the use of a software-based solution to measure latency. Furthermore, we also propose an extension that serves to measure bandwidth as well, with the novel concept of convoy of packet trains. |
