A scalable architecture for maintaining packet latency measurements
Latency has become an important metric for network monitoring since the emergence of new latency-sensitive applications (e.g., algorithmic trading and high-performance computing). To satisfy the need, researchers have proposed new architectures such as LDA and RLI that can provide fine-grained latency measurements. However, these architectures are fundamentally ossified in their design as they are designed to provide only a specific pre-configured aggregate measurement—either average latency across all packets (LDA) or per-flow latency measurements (RLI). Network operators, however, need latency measurements at both finer (e.g., packet) as well as flexible (e.g., flow subsets) levels of granularity. To bridge this gap, we propose an architecture called MAPLE that essentially stores packet-level latencies in routers and allows network operators to query the latency of arbitrary traffic sub-populations. MAPLE is built using scalable data structures with small storage needs (us...
