網路通訊學習方案
Digital communications training solution
 
簡介
 

與傳統不同的網路實驗不同的是,這個系統讓學生了解到廣泛不同的數位網路通訊技術。這個教學方案分成兩個階段,首先是提供一個高階的環境,讓學生可以輕易的學習email以及網站伺服器的架設。利用FlowCode流程式語言的巨集,提高了學生學習的動機。
第二階段是進階的學習,當我們在使用電腦及瀏覽器的時候 這個系統讓學生可以導出一個範圍很廣的實驗 讓學生了解現代數位通訊中的協定包含乙太網路,DLC,MAC,ARP,TCP,IP,UDP,ICMP,HTTP及POP3等,在OSI的相關位置。

這個方案建造了一組嵌入式網路系統,包含兩個網站伺服器。學生使用硬體以及四組FlowCode巨集。讓學生可以接觸到MAC,UDP ,TCP,IP層。學生透過許多的實驗,建構自己的系統,開始從MAC 層一步一步建立,最後使用FlowCode巨集建立TCP層如Email server及Web server以及防火牆應用。

Benefits
 
• Extremely economical solution to learning internet protocol and digital
communications.
• Teaches many aspects of OSI model technology in an electronics context.
• Highly motivating resource that allows surprisingly functional systems
to be created.
Features
 
• Includes two web server boards
• Allows students to explore MAC, IP, ARP, UDP and TCP protocols
• Allows students to set up a firewall
Description
 
This extraordinary training solution allows students to carry out a wide variety of investigations into digital communications technology in an internet technology context. The solution can be used at two levels: at technician level very high level Flowcode macros allow students to easily incorporate email and web page construction technology—integrated with Flowcode variable.s.— which provides a highly motivating platform for a wide variety of programming tasks.
At a higher academic level, when used in conjunction with a PC and a web browser, this equipment allows students to conduct a range of experiments that builds understanding of modern digitalcommunications protocols including Ethernet, DLC, MAC, ARP,TCP, IP, UDP, ICMP, HTTP and POP3 protocols and their relative position in the OSI model.
The solution consists of a pack of E-blocks that form an embedded internet solution—including two web servers. Students use the hardware and four sets of Flowcode macros that allow students to access at the MAC, UDP, TCP and IP layers. Students progress through a number of exercises to build their understanding: starting with byte-by-byte packet construction at the MAC layer, and building up to constructing advanced systems including an email server, web page server, and firewall using Flowcode macros at the TCP layer.
Learning objectives
 
Technician level:
• Fundamentals of flow chart
programming in an internet context.
• Construction of embedded internet
systems providing with web page
server and email functions
Undergraduate / BTEC level:
• Understanding of packet structure,
and construction, at MAC and all
higher protocol layers
• Understanding of communication
strategy and information flow at
MAC and higher protocol layers.
Tasks included in the manual are:
1. ARP scanner
2. Ping
3. Time and date using UDP
4. Sending HTML using HTTP
5. Receiving HTML
6. Sending an email using SMTP
Advanced tasks
1. Custom messaging using UDP
2. A firewall application
