“…Secondly, considering the burstiness on traffic in today's backbone networks, fine-grained and realtime monitoring is desired [21]- [23]. Nevertheless, finegrained and realtime monitoring would lead to unbearable complexity and flood the NC&M system with tremendous status data [24]- [26], if it is based on a centralized scheme. Lastly but not the least, the monitoring scheme should be programmable to reveal the end-to-end information of an arbitrary flow with high accuracy and minimum overhead.…”

Nowadays, with the fast development of backbone networks, performance monitoring and troubleshooting on IP-over-optical networks have become increasingly important. However, a real-time monitoring scheme, which is programmable to reveal the end-to-end multilayer information of an arbitrary flow in an IP-over-optical network, is still absent. Also, for such a monitoring scheme, how to balance the tradeoff between the accuracy and the overhead has not been studied yet. To address these challenges, we design a P4-based flexible multilayer in-band network telemetry (ML-INT) system to visualize an IPover-optical network in real time. Specifically, the flexible ML-INT scheme only selects a small portion of packets in an IP flow to encode INT headers, while each INT header only contains a part of the statistics of all the electrical/optical network elements (NEs) on the flow's routing path. We design the packet processing pipelines for the scheme, program P4-based hardware programmable data-plane (PDP) switches to implement the pipelines, develop the optical performance monitors that can cooperate with the PDP switches to facilitate ML-INT, and implement a high-performance data analyzer that can extract, parse, and analyze the INT data carried by the high-speed IP flows [i.e., with an arrival rate up to 2 million packets per second (Mp/s)]. The whole flexible ML-INT system is experimentally demonstrated in a small-scale but real IP-over-optical network testbed. The experimental results verify that our proposal only introduces very small overhead and can make the IP-over-optical network more visible in real time for performance monitoring and troubleshooting. INDEX TERMS IP-over-optical network, multilayer in-band network telemetry (ML-INT), programmable data-plane (PDP). I. INTRODUCTION Recently, with the development of emerging network services, both the traffic and infrastructure of backbone networks are undergoing dramatic changes [1]. Specifically, the traffic has been not only growing exponentially in volume but also becoming increasingly bursty and dynamic [2], [3], and this has applied heavy pressure on the rigid IPover-optical infrastructure of backbone networks [4]-[6]. Therefore, network operators first need a much more flexible network architecture that can build dynamic lightpaths adaptively in the optical layer for time-variant traffic flows in The associate editor coordinating the review of this manuscript and approving it for publication was Wei Quan.

Optical networks are vulnerable to a range of attacks targeting service disruption at the physical layer, such as the insertion of harmful signals that can propagate through the network and affect co-propagating channels. Detection of such attacks and localization of their source, a prerequisite for secure network operation, is a challenging task due to the limitations in optical performance monitoring, as well as the scalability and cost issues. In this paper, we propose an approach for localizing the source of a jamming attack by modeling the worst-case scope of each connection as a potential carrier of a harmful signal. We define binary words called attack syndromes to model the health of each connection at the receiver which, when unique, unambiguously identify the harmful connection. To ensure attack syndrome uniqueness, we propose an optimization approach to design attack monitoring trails such that their number and length is minimal. This allows us to use the optical network as a sensor for physical-layer attacks. Numerical simulation results indicate that our approach obtains network-wide attack source localization at only 5.8% average resource overhead for the attack monitoring trails.
