Unified Latency Management
Combining Network and Application Layer Visibility to Achieve Superior Latency Performance
Which comes first, the application or the network?
Trading and market data applications are by their nature highly distributed and depend on fast communication between many interacting components to do their work. Successful trading requires low latency performance from each of the individual components involved and from the networks that they use to communicate. Visibility into latency at both the application and network layers is therefore essential in order to fully understand and manage its end-to-end trading impact.
Traditionally, management systems have tended to focus on performance monitoring within particular parts and layers of the ecosystem. But users often find that it’s difficult to manage the network and application layers in isolation. For example at the network layer, it’s hard to maintain a proactive approach to troubleshooting without visibility into the issues being experienced by application end-users. In addition, important network investment decisions – for example, which extranet service to select or whether to upgrade particular exchange connections - need to be guided by knowledge of how they will impact the performance of the applications and the business.
