[調査目的]
・かねてよりTA社本店と、JDCとのネットワーク接続が不安定となる課題があった
・本店によるこれまでの確認では、週に1～2回トラフィックの急増が見られたが、それ以外の時間帯も不安定であるとの問合せがあった
・今般、その原因を突き止めるべく、現地で通信テストを行い、異常がないか本店からも監視しチェックする
[やったこと]
1. 通信不具合の詳細について、JDCスタッフへのヒアリング
2. JDC倉庫にあるPCからの通信テスト及びその通信ログの取得

[investigation purpose]
・ There was the problem that unstable network connection between head office of TA and JDC.
・ According with the information from head office, they could find rapid incrreasing of network traffic once or twice in a week, and even other times they could find unstable network condition sometimes.
・In order to discover the casue, I will test network on local and check whether there is not abnormality
[What we did]
1. Hearing form JDC staff about the details of the network malfunction.
2. Getting log of the network test from the PC in the JDC warehouse.

3, Connect PC of engineer to network of JDC warehouse, and obtain communication test and its communication logo.
4. Monitor the communication from main store and check if trouble occured in communication.
(Result(summary))
At first, it was understood that the communication was always unstable, but it was only what specified staff felt about. What affects all staff was only once a week(once a month recently)
As for specified staff, I checked what happened and found the cause might be attributed to the problem of PC. Then, I decided to replace at first.
