Addressing Overhead Concerns Figure 6 depicts packet exchanges under all three scenarios. Critics will be quick to point out that the use of the RTS/CTS mechanism results in additional network overhead and reduced throughput. It must be emphasized that the increased overhead is really a consequence of the use of the CCK/Barker preamble/header rather than due to RTS/CTS itself. In this mode, only those mobile clients sending high-rate OFDM packets must precede transmission with an RTS/CTS exchange. Obviously, the RTS/CTS exchange is unnecessary for legacy 802.11b equipment in this situation.

Mesh networks also offer advantages in fault containment. Each node is responsible for its own traffic. With good flow control, a failure in a node does not impact other nodes. The same fail over mechanism for sparing any module causes fail over of the fabric connections. Many star fabrics, on the other hand, use a proprietary mechanism for synchronizing mirrored” data through the fabric. These mechanisms can vary in quality and robustness depending on the fabric vendor. They also place additional capacity demands on the fabric itself adding to the provisioning costs.

The Ethernet MAC frame is illustrated in Figure 3 . The shaded part is mapped into GFP.

Integrating an off-the-shelf cryptographic chip with a network processor is not a trivial engineering feat. While NPUs are a great leap ahead of general-purpose CPUs, they aren't entirely optimized to the specific task required for SSL processing. Read the fine print. For example, a network processor that can perform Layer 2 classification at Gigabit Ethernet (GbE) rates may have a difficult time keeping up with the Layer 4 classification needed to segregate SSL traffic. If a GbE NPU can't keep up and the next available speed grade is a 10-Gbit part, you may be forced to buy more capability than originally planned.

To characterize the speakers and microphones on an IP Phone, the developer must determine the relationship between sound pressures and voltages on either side of a transducer. This process is partially automated by the RTT Sensitivity Measurement Tool. The software uses a second IP Phone development board as a Measurement Unit, generating output test signals and measuring input signals. Once this measurement board is calibrated, RTT can use the results to determine the response of the IP Phone being tested.

The CM will wait opportunities to transmit real-time VBR traffic and piggyback bandwidth request for the following frame. The pseudo-code implemented in cable modem is as follows:

Silicon IP Several notable silicon IP (SIP) cores were discussed at the show. Saturn, the first product from Adelante's Galaxic DST Technology, is a reconfigurable and extendable soft DSP core that boasts some impressive numbers”0.25 mW/MHz power dissipation and a performance level of 420 MMACs/sec from a 0.18-micron CMOS process. Saturn employs a dual Harvard architecture and three-stage pipeline with 16-bit data and instruction words. In only 40,000 logic gates, the core comprises two 16-bit multipliers, four 16-bit ALUs, two address calculation units, barrel shifter, a program control unit, a hardware loop control unit, a saturation and shift unit, and a bit-manipulation unit. There are two data memories, each of which can be as large as 64 K words by 16-bits. Saturn is fully static, allowing it to run at clock frequencies from 0 to 210 MHz.
