The research on Internet traffic classification and identification, with application on prevention of attacks and intrusions, increased considerably in the past years. Strategies based on statistical characteristics of the Internet traffic, that use parameters such as packet length (size) and inter-arrival time and their probability density functions, are popular. This paper presents a new statistical modeling for packet length, which shows that it can be modeled using a probability density function that involves a normal or a beta distribution, according to the traffic generated by the users. The proposed functions has parameters that depend on the type of traffic and can be used as part of an Internet traffic classification and identification strategy. The models can be used to compare, simulate and estimate the computer network traffic, as well as to generate synthetic traffic and estimate the packets processing capacity of Internet routers KEYWORDS Packet-switching networks, Measurement, Modeling, Statistical methods & Packet length.

“…However, it presents a performance degradation problem within a real system, especially for the critical data with small latency. In [9], two methods based on packet network traffic measurement are studied by simple sniffers and the transformation of captured packet traffic into data source statistics. The TCP/IP protocol stack and fragmentation/defragmentation procedures are considered according to RFC 793.…”

“…In most cases, the length of the transmitted data is longer than that of the packages. The data source and packet traffic must be connected by fragmentation and defragmentation processes [9,13], which can be realized through dual-port static random access memories (SRAMs) (Dual-Port SRAM_1 and Dual-Port SRAM_2). Two SRAMs are used to improve the frequency incompatibility between Ethernet (125 MHz) [14] and USB (100 MHz) [15].…”

This paper proposes an Ethernet packet transformation and transmission architecture between Modbus transmission control protocol (Modbus TCP) and universal serial bus (USB) 3.0 developed with a field-programmable gate array (FPGA) development kit. The proposed architecture is used to complete packet transformation and transmission between Ethernet and USB 3.0 for application in induction motor (IM) control. The Ethernet receiver receives and analyses Modbus TCP packets and sends the source address, destination address, IP header, and Modbus TCP header to the register to verify the correctness of the packet. The Modbus TCP packet is stored in static random access memory and awaits access through a USB 3.0 module. An FPGA development kit (Intel DE10-Standard) is used for functional verification. The measured results show that the latency, throughput, and dynamic power are 18.845 μs, 950.31 Mbps, and 142.17 mW, respectively, at a voltage of 1.8 V and an operating frequency of 125 MHz. The main advantage is that the proposed Ethernet and USB bridge performs high throughput and short latency with FPGA development kit and that an application specific integrated circuit (ASIC) is provided with low power consumption. The robustness and convenience of the proposed ASIC are especially advantageous. The motivation is to resolve an existing problem that Ethernet and USB operate on different platforms.
