Abstract:
PURPOSE: A method for managing ATM performance information of a switching system using an SNMP(Simple Network Management Protocol) is provided to filter data according to a performance processing method of an SNMP agent for much performance information, and to report changed information only to a manager system, then to manage previous performance data, thereby reducing load of the manager system. CONSTITUTION: An SNMP agent computer drives a communication channel with communication middleware of a switching system(S01), and drives a communication channel with a manager computer(S02). The SNMP agent computer checks whether a performance information collection setup/cancellation request message is received(S03). If so, the agent computer calls a library of the communication middleware(S04), and performs performance collection setup/cancellation registration(S05). If a complicated performance information request message is received(S07), the computer retrieves an OID(Object ID) value(S08). If the OID value does not exist, the computer extracts the value from history MIB(Management Information Base) data, and calculates the value by integrating performance data(S09). The computer makes a PDU, and transmits the PDU to the manager computer(S10).

PURPOSE: A method for maintaining consistency is provided to keep the data consistency between a web server and a web cache server by offering a web service through the flexible installation of the web cache server having a web cache table on a routing path according to the active network environment. CONSTITUTION: After receiving the data from the web server(21) and checking if the data is a valid packet, the web cache server(22) search a cache table(221) and performs the update in case that the same data exists. If the same data does not exist, the web cache server registers the data on the cache table and records the data on a routing table(222). After receiving the message containing the expiration date from the web server and checking if the message is valid, the web cache server stores the message to the cache table and performs the web cache service during the period of validity. In conclusion, the web cache server keeps the data consistency between the web server and the web cache server through the data update by receiving the message including the update time from the web server.

외부 시스템과 연동하여 고객 맞춤형 모니터링 서비스를 제공하는 고객 맞춤형 SLA 모니터링 관리 시스템은 외부 시스템과 연동하여 모니터링 서비스에 가입한 고객의 회선에 대한 외부 지표 오더를 수신한다. 그리고 고객 맞춤형 SLA 모니터링 관리 시스템은 외부 지표 오더에 포함된 고객의 요청 사항을 SLA 관리 데이터에 반영하여 SLA 관리 데이터를 갱신한다. 갱신된 상기 SLA 관리 데이터를 이용하여 외부 시스템을 모니터링 할 지의 여부를 결정하고, 결정된 결과에 따라 고객의 회선과 외부 시스템을 통합 모니터링한다.
Abstract:
PURPOSE: A mobile management apparatus for providing three dimensional conversation type advertisement and method thereof are provided to schedule advertisement content according to each mobile location by receiving the location information of a user. CONSTITUTION: A profile management unit(110) manages a location profile of a playback apparatus center and a user profile. A mobile management unit(120) manages mobile routes of a user. An environment generation unit(140) detects advertisement according to the mobility of the user based on the mobile routes and the location profile and the user profile. The environment generation unit generates environment data of a display apparatus(200) for reproducing the advertisement.
Abstract:
PURPOSE: A 3D image displaying device using head positional tracking and an operation method thereof are provided to display different 3D images according to of viewpoint of each of a plurality of users. CONSTITUTION: An image processing unit(110) produces a user location from a reference point. According to the produced user location, 3D contents are transmitted from a contents server(30). The image processing unit outputs a 3D image. In the 3D image, the 3D contents are processed at the viewpoint of the user. A display unit(160) displays the 3D image to the user.
