Using the Network Cache

The network or IP caching feature stores accepted, incoming TCP requests, so they are not sent to the database; instead, they are permitted automatically with the syscall function. This feature improves performance for hosts, which launch many incoming TCP connections.

To activate the IP caching feature, change the following tokens in the [seosd] section of the seos.ini file and restart CA ControlMinder:

network_cache_timeout

Defines how often to clean the cache table. This token is important if you want to set time limits for the accept requests.

UseNetworkCache

Set this token to yes to activate IP caching.

When caching is enabled, all accepted TCP connections are saved in the kernel table. The records consist of a peer IP address, peer port, and local port. Every new connection is searched in this cache. If a matching set of data for IP address, IP port, and local port is located, the connection is immediately permitted. The time to establish connection is reduced.
