Latency Measurements

Whether you have sufficient bandwidth or not, what really matters to the majority of today's applications are the latency and jitter characteristics of the link. With modern queuing technologies, even high bandwidth utilization may not have an adverse impact on the quality of the services provided by the link. Technologies such as Cisco IPSLA and Juniper RPM can help continuously monitor these very important KPIs at very good resolution. Since you can use these technologies to run tests that look like the real applications (HTTP, DNS, specific ports and not just ICMP), the traffic generated by them will be queued and treated as if it is the real thing-giving you a very accurate picture. Monitoring them continuously can help build good baselines and spot deviations immediately.

Managing bandwidth needs and consumption is a discipline that has existed since the first 150bps modems connected computer systems together. Today, with multi-gigabit links becoming an everyday reality, we are still facing the same conundrums. Only the number of zeros has changed.

Vess Bakalov, CTO for SevOne Inc., says one thing to remember is that bandwidth and bandwidth management is a means to an end, and not an end in itself.  We need adequate performance for our applications and users for the minimum expenditure. To do this effectively, we must first understand what “adequate” means for these users and applications. Only once this often-omitted step is completed can we effectively employ any bandwidth management techniques.

Check out this list of five quick tips on better bandwidth management.
