Whereas operators are often attentive
to high IP bandwidth consumption
such as P2P file-sharing behaviors,
airtime and signaling resources can
also become exhausted. Leaving VPN
connections open for hours when
totally unused, for example, can
eat up scarce airtime resources in
the cell, and mobile e-mail deliv-
ery devices create signaling loads
disproportionate to the light IP
capacity they require. The Alcatel-
Lucent 9900 Wireless Network
Guardian provides full visibility into
how real end-user behaviors impact
network utilization, enabling QoS
adjustments in real-time and better
network planning. This represents
a first step into deep packet inspec-
tion technology. The Alcatel-Lucent
End-to-End IP Wireless-Broadband
Solution roadmap calls for integrating
application-assurance capabilities,
such as tiered service quality, into
the solution using Alcatel-Lucent
service-edge routers in the near future.
