Due to the down of both systems of this device group, this influence has spread to other devices, and a large number of alarms are issued. Since the conventional display screen only displays a large number of alarms on the display screen, it is difficult for the viewer to grasp the cause of the abnormality. However, since the screen display device 200 maps the alarm around the cause location on the display screen, the viewer can easily guess the location (center) of the abnormality on the display screen. In addition, the warning display of the device and the link on the display screen makes it easier for the viewer to guess the failure range.

Abstract
Description
さらに、図11に示すように、画面表示装置200は、三次元表示画面上にフロー157(パケットの流れ)を示す破線矢印を重畳して表示するとともに、障害によりそのフローが途絶するポイントがあれば、そのポイント158を×印で示す。これにより、閲覧者は異常の原因個所を推測しやすくなる。
次に、図12を用いて、画面表示装置200の構成を説明する。画面表示装置200は、前記したとおり、NWの全装置の階梯や接続関係、複数系を組む個所の情報、各種警報や障害の発生状況を示した三次元表示画面を生成する。この画面表示装置200は、NWを構成する各装置(例えば、図9に示す転送装置121,122、制御装置141、上位サービス装置161、下位サービス装置101~103)と接続されており、これらの装置から、NWに関する警報やフローの流量情報を受信する。また、画面表示装置200は、閲覧者から画面表示に関する各種指示入力を受け付けるキーボードやマウス等の入力装置400を接続している。また、画面表示装置200は、画面表示を行う液晶ディスプレイ等の表示装置300を接続している。画面表示装置200は、入力装置400からの指示入力と、各装置から受信した情報とに基づき、NWの状況を示す三次元表示画面を生成し、表示装置300に出力表示する。閲覧者は、この三次元表示画面を見ることでNWの状況を確認する。
次に、図12,13を参照しつつ、図14を用いて画面表示装置200の処理手順を説明する。
なお、図12の画面表示装置200の表示用情報生成部226は、入力装置400経由で入力された指示入力に基づき、三次元表示画面に表示する情報の絞り込みをするようにしてもよい。例えば、表示用情報生成部226は、指示入力に基づき、図15に示すように、画面上に、制御およびサービスに関する項目(ここでは、装置とリンク)を表示し、装置間リンクおよび転送装置を非表示としてもよい。
また、画面表示装置200は、三次元表示画面生成において、どの視点のどの方向から見た三次元表示画面を生成するかの選択入力を受け付けてもよい。つまり、画面表示装置200は、画面表示において、視点の位置および向き(以下、まとめて「視点」とする)を自由に選択可能としてもよい。すなわち、例えば、画面表示装置200は、画面の閲覧者の選択入力に基づき、図16Aに示す三次元表示画面を、視点1(垂直な視点)や視点2(水平な視点)から見た表示画面を表示してもよい(図16Bまたは図16C参照)。
また、表示用情報生成部226は、表示画面上において、警報の種別により異なる表示色や大きさ等で警報を表示することで、画面の閲覧者が重要障害発生ポイントを識別しや
すくするようにしてもよい。例えば、表示用情報生成部226は、図18に示すように、重要度が高い警報と、重要度が低い警報とを異なる大きさのアイコンで表示して識別できるようにしてもよい。さらに、表示用情報生成部226は、直近所定時間以内に発出された警報を点滅等で表示してもよい。これにより、画面の閲覧者は、表示画面上でNWの状況変化を把握しやすくなる。
さらに、画面表示装置200は、画面の閲覧者が選択した過去のある時刻から現在までのNWの障害の状況の変化を連続的に表示するようにしてもよい。すなわち、画面表示装置200は、過去から現在までのNW状況をプレイバック表示できるようにしてもよい。
