Overview of System Architecture
Have a glance at Figure 1. The configuration is a 3-layer structure. Every
element has capability to link with its peers and upper/lower layer. Much like
the up-to-date cellular network, almost all kinds of data can be tranceived th-
rough the system. Mythril didn't request a system for massive users, so circuit
switching became the switching measure of the chioce [2].
Normally links between layers are required to have the overall system work
out, while those within one layer are not, though they may improve system effi-
cency and robustness. Links between peers can also privide another advantage.
When overall system are down, partial system may still work, which means parti-
al effectiveness are allowed. The more detailed description will be given in l-
ater sections.
This somewhat complicated architecture have disadvantages, too. Versibility
often brings huge bill, but as mentioned before that's not a problem. And thank
to advanced fabrication technology provided by other IEEE experts, malfunction
rate of components is lower than expected. Minimization of devices (both number
and size) could have been a difficult problem, but by using certain design tec-
hniques we managed to get it solved. Thus the system satisfies the demands of
stability and portability.

系統架構概觀
請見圖1，該架構是一個三層式結構。每個單元都有能力與同儕和上/下層建立連結。
各種型態的資料都可以透過這套系統收發，與最先進的手機網路類似。為大量使用者提供
服務並非「密銀」的要求，所以在交換技術上我們使用線路交換 [2]。
正常而言，為使整體系統能夠運作，建立各層之間的連結是必要的，而同一層內的連
結並非必要，但它們可能增進系統的效率和強固程度。與同儕的連結同時也提供另一項優
點：當整體系統無法運作時，部分系統仍然可能正常運作。之後的章節會作更詳盡的解說
。
這個有些複雜的系統也有缺點。多功能通常代表高價格，當然如前述我們並不為此感
到困擾。並且，得力於其他IEEE專家提供的先進製造技術，原件的故障率比預期要低。裝
置的微型化(包含數量和大小)原本是個可能的難題，但我們藉由某些設計技巧解決了。因
此，這套系統滿足了穩定和輕便的要求。
