This article focuses on packet filtering firewall used on gigabit network and presents a packet classification algorithm called HSBIPG(Hash Search Based on IP Group). Then we analyze advantages and disadvantages of this algorithm. Finally, we implement a line rate gigabit packet filtering firewall using this algorithm on IXP2400 network processor and it proved to be feasible and efficient by experiment.

3. Designed and realized a high speed table lookup pipeline by "FPGA+TCAM+SRAM" to satisfy the 10Gbps line speed lookup of the 40 bytes packet length , this pipeline design can implement lookup speed at 100 million searches per second.
This paper analyzes the iuput and output processing flow in the 10G LAN convergence interface board, realizes line speed disposal of 10G with pipeline processing architecture, and realizes a high speed table lookup pipeline by "FPGA+TCAM+SRAM" which can implement the lookup speed at 100 million searches per second.
The above principles can guarantee forwarding of IP packets at line rate.
The resulting header can be processed using slower electronics than the line rate without any sacrifice of the information transfer rate and with higher immunity with respect to degradation of the optical signal-to-noise ratio (OSNR).
Additional Preamble bytes may be necessary depending on the expected receiver characteristics and the transmitted line rate.
Additional Postamble bytes may be necessary depending on the expected receiver characteristics and the transmitted line rate.
A modern IA32 server can comfortably handle a 1Gb/s Ethernet interface at line rate with most of its CPU cycles to spare.
Fiber orientation in the production line is good and stable irrespective of position across the width of the production line, time of day and changing line speed.
Ther evaluation is independent of the line speed up to 325 m/min.
The hyperspectral online line-scan system was integrated with a commercial apple-sorting machine and evaluated to inspect apples for fecal contamination and defects at a processing line speed of over three apples per second.
Important parameters are the user's peak transmission rate p, which is the access line speed, the user's guaranteed minimum rate r, and the bound ε on the fraction of lost data.
The results of laboratory and mill tests are compared with the predictions of the analytical model and engineering considerations for jet nozzle operation to reduce coating weight at increased line speed are discussed.
