EXTENT-2016: Network Instrumentation Challenges and Solutions

  1. 1. Claude Robitaille CTO Accedian Networks Network instrumentation challenges & solutions

  3. 3. 3 ©2015 ACCEDIAN NETWORKS Company Confidential “For performance, compliance, analytics” INCREASING NEED FOR VISIBILITY The Finance sector is increasingly adopting outsourced services. As a result the Regulatory and Service expectations are driving: • Increasing levels of transparency • Costs • Service levels • Performance This drives the need for greater visibility, analysis, and auditability of data: • Granular, precise Extranet performance assurance for an exceptionally fast, reliable, global infrastructure • Ubiquitous flow capture and time-stamping, for compliance and trade flow analytics analyze and optimize and account for every transaction All this is driving a new breed of instrumentation and analytic capabilities.

  7. 7. 7 ©2015 ACCEDIAN NETWORKS Company Confidential “You can’t control what you can’t see.” ASSURING EXECUTION SPEED 1. Low- Latency • High Frequency Trading (HFT) trading is ultra-competitive. Architectures that deliver the lowest latency solution are the difference between profit and loss. 2. Accurate Measurements in Sub-Second Timescales • Traditional network measurements take place over timescales of seconds and minutes: providing little or no insight into behavior at the ms, µs and ns timescales that determine success 3. Throughput Micro-Burst Reporting • Activity on the network occurs in bursts, which cause queues to build up and buffers to overflow. Visibility into these short-lived conditions is central to understanding network performance.

  11. 11. 11 ©2015 ACCEDIAN NETWORKS Company Confidential A CASE FOR NETWORK-LAYER INSTRUMENTATION: MIFID II TIMESTAMPING / AUDIT Synchronise the clocks across every software application (requiring a costly upgrade to every system in the bank) and store data from EVERY individual flow into a single repository? OR source the data from a single source, the NETWORK, giving a secure, synchronised and timestamped audit record. level of accuracy presents some tough choices….
