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-LucentEnd-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.
