Now that so many of you (73%, according to the WildPackets survey The State of Faster Networks) have at least some 10G in your networks to accommodate your increasing network load, it’s time to effectively deal with the complexities that often follow. With a significant increase in bandwidth over your legacy 1GbE segments, monitoring, managing and troubleshooting network segments can be challenging.
So what can you do to address this increased management complexity? Which techniques that worked well with 1GbE network segments should be avoided? And what best practices should be applied? These are all questions that WildPackets’ webcast, titled “Best Practices for Analyzing 10G Ethernet Traffic,” addresses. Without giving everything away, here’s a quick look at the best practices for 10G Ethernet traffic analysis.
- Upgrade your Network Analysis: As part of any 10G upgrade you should also plan on upgrading your network analysis solution. WildPackets Omnipliance family of analysis and recorder appliances offers a powerful, precise, and affordable solution to meet any needs. And with network recording at over 20Gbps, you’ll never miss a beat on even your most heavily subscribed 10G network segments.
- Be Specific: Be direct with your analysis requirements as there are a lot of “question marks” in your network. For example, where do you want to capture data and which information should you be collecting?
- Know your Network: From a traffic perspective, it’s important to understand the utilization levels per segment as well as traffic types per segment before you jump into analysis.
- Analyze the Essentials: Just because you have the ability to analyze everything, doesn’t mean you have to. Disabling analysis options that you don’t need and focusing on the essentials will help significantly increase performance.
- Filter and Slice: Before analyzing data, you must filter and slice. Filtering specific subsets of data that are most important will help improve performance, while slicing, or choosing a specified number of bytes from each packet, will greatly reduce the analysis and storage load.
- Anticipate Hardware Resource Needs: It’s important to anticipate the resources you are going to need specifically in terms of disk space and RAM.
- Be Reasonable: Keep users in check on a distributed system by nominating an “owner” for each system and keeping multiple users organized and focused on the same analytical tasks.
