Traffic mirroring is a Cisco SCE platform capability that complements the range of services provided by
the SCA BB solution. It copies a specified portion of the traffic streams and sends this copy to third-party
servers who do offline analysis.
The criteria for traffic mirroring is based on Layer 7 attributes and subscriber awareness. This fine
granularity, along with load sharing capability for servers providing the same service, substantially
reduces the number of solution components.
The traffic that is copied is also processed by the SCA BB application and forwarded without
interruption to its original destination. The copy of the traffic is presumed not to return to the Cisco SCE
platform after being processed by the third party servers.
Using Traffic Mirroring for Behavioral Targeting
Today Internet advertising is being executed by content providers (or publishers) in collaboration with
ad networks, which actually handle the syndication of ads from advertisers to web sites. The Cisco
Service Control behavioral targeting solution provides the means for service providers to participate in
the business of the online advertising. This solution allows the SPs to leverage their information about
the subscribers and enables highly targeted advertising.
Based on Deep Packet Inspection (DPI) and subscriber integration, the Cisco SCE 8000 platform filters
out only what is relevant for the subscriber profiling. This greatly conserves the resources of the
advertising servers, by eliminating the irrelevant web traffic before it even reaches them. This filtered
traffic is processed as usual by the SCA BB application along with the rest of the traffic, but in addition
a copy of it is passed to an external device which can do offline analysis on the subscriber behavior. The
data can then be used for the targeted advertising.
Behavioral Targeting is accomplished using several Cisco SCE platform capabilities. This section
describes the intelligent traffic mirroring capability, which is one of the features that enable the solution.
