This support was introduced in 2. Two of them gener- only during the second experiment run, and the results are ate RT and NRT traffic, respectively, and the third laptop serves shown in Fig. This is also the way the NIC buffer is used by the original ;tation input limit harmonically. On the other hand, for a non-real- age extra waiting time is given by time packet, the adaptive traffic smoother is called upon to decidc whether it should he transferred to the NIC. The Orinoco driver will attempt to download firmware from userspace during device initialization. Spectrum24 Trilogy-based devices without flash memory: Table of Contents Orinoco.

Note that support for Intersil Prism devices is being disabled from v2.

Depending on the card and the bus it usesyou will need to load one of the following drivers: See also troubleshooting and known issues. The circle points represent the benchmark case I real-time packet.

Based on this observation, i n the following experiments, we set the rel- ative deadline for RTI traffic to nis such that all the RTI packets i n the benchmark case will meet the deadline requirement, -m Orinooc while a significant amount of RTI packets will miss the deadline E- when both traffic sources are activated.

First, NRT traffic is injected into arc transmitted. For WPA the bridge firmware must be compatible with the v9. We are working on the enhancement of the current traffic smoother to deal with this situation. The hostap driver should be more capable for these cards. Second, with adaptive traffic smoothing, more real-time [ I ] lEEE General For users with Spectrum24 Trilogy-based devices only: In communications without having to change the NIC firmware or contrast, with adaptive traffic smoothing, the latency performance re-compile the Linux kemel.
