There are, of course, other important settings while getting a test to run and end up with similar
numbers. For complete details, please contact the Cisco IPS team.
When placed in these test environments, the high performance Cisco IPS 4270 sensor produces
the following results:
Table 2.
Performance characteristics of Cisco IPS 4270 sensor
Media-Rich
Transactional
Throughput
4 Gbps
2 Gbps
Connections/sec
10,000
20,000
Concurrent Connections
100,000
200,000
It is important to understand that these numbers represent a maximum supported load and were
taken while under a >95% CPU load. Both tests were run over a 3 day period and in neither case
were Web Avalanche sessions impacted. In a production deployment, we recommend you apply
industry standard network device sizing techniques.
Conclusion
Network environments and traffic profiles continue to change and evolve. These changes have
resulted in shifts of not only the type of traffic but the characteristics of that traffic. Due to a highly
variable performance envelope for an IPS system, there is no such thing as a one size fits all
performance metric. Cisco now provides two metrics to use to help appropriately place IPS
technology into existing networks. The two metrics used are based on typical transactional and
media rich environments. With a better understanding of how devices work in multiple
environments, IPS sensors can be more effectively deployed in modern networks.
