A new perspective on Network Visibility - RISK 2015
The document discusses network visibility solutions from Net Optics and Ixia. It summarizes that Net Optics was acquired by Ixia but will remain a brand name. It then discusses challenges of network growth outpacing monitoring tools, security threats increasing, and the need for improved network performance and visibility. The document promotes Ixia and Net Optics solutions like network taps, packet brokers, and virtual monitoring tools that provide intelligent traffic distribution and filtering to gain complete network visibility without blind spots.

- 16. Traditional access methodsdon‘t work! 1. Dropping packets 2. High switch CPU and memory load 3. Doesn‘t forward L1/L2 errors 4. Needs to be configured 5. Mixing source/destination information 6. Limited number of SPAN ports 7. Compliance issues!!! 8. Distorts packet arrival times SPAN port
- 17. Step 1: useNetwork TAP instead of SPAN Benefits • 100% visibility, no dropped packets • Doesn’t affect switch CPU and memory • Plug-and-play — no configuration required • Permanent access: no need to break the link each time you need to remove tool • Forwards important L1 and L2 errors • Dual power supplies: keeps the network link up and running in case of power failure • Doesn’t change packet arrival times SwitchFirewall Analyzer Switch

- 29. De-duplication 2 3 45 6 7 8 9 input packets duplicated packets 1 21 3 4 5output packets = 9 * 1580 bytes = 14220 bytes = 5 * 1580 bytes = 7900 bytes 55% traffic reduction
- 30. Packet Slicing Problem: In manycases only the header is needed for analyzing. Forwarding a 1500byte packet to a probe does consume more memory at the disk than a 64byte packet. If the data content is not needed this would be wasting recourses beside that it does consume bandwidth on the downlink to the probe. Solution: A Network Monitoring Switch does remove the data content of a packet before the packet will be forwarded to the probe. The user can define by the GUI what header information will retrain after trimming. MAC IP Data FCS MAC IP FCS
- 31. Port tagging Network Scenarios DMZSegment Database Farm Tag 1 Tag 3 Tag 2 Server Array Problem: When aggregating packets over multiple TAPs, it’s no more possible to identify from which TAP they have been originally taken. Measuring the delay e.g. through a Firewall would result in the need of an additional probe. This is costly. Solution: By adding a Port TAG to the packet, the Network Monitoring Switch provides full visibility again and for the Firewall example one probe would last.
- 32. Timestamping for precise measurements Thefirst four bytes of the timestamp are a 32-bit binary value in seconds. The second four bytes are a 32-bit binary value representing tenths of microseconds; The final four bytes are reserved for use when higher-precision timestamping becomes available, making the timestamp format capable of supporting a resolution of 0.1 picoseconds.
