System and method for endpoint discovery based on data distribution service
First Claim
1. A system for endpoint discovery based on the Data Distribution Service, the system comprising:
- a discovery information collecting part that collects first discovery information about a first domain network in which a plurality of endpoints comprising a first endpoint are interconnected, and that collects second discovery information about the first domain network after a preset period of time after collecting the first discovery information; and
an endpoint discovery part that detects a second endpoint that is added to or deleted from the first domain network by comparing the first discovery information and the second discovery information, and that transmits information about the second endpoint to the first domain network when the second endpoint is detected, and that discovers the first endpoint having the same topic information as the second endpoint and that transmits the information about the second endpoint to the first endpoint, wherein the discovery information collecting part collects location information of the topic name nodes at the lowest layer of the tree structure.

Abstract
Disclosed are a system and method for endpoint discovery based on the Data Distribution Service. The endpoint discovery system includes: a discovery information collecting part that collects first discovery information about a first domain network in which a plurality of endpoints including a first endpoint are interconnected, and that collects second discovery information about the first domain network after a preset period of time after collecting the first discovery information; and an endpoint discovery part that detects a second endpoint that is added to or deleted from the first domain network by comparing the first discovery information and the second discovery information, and that discovers the first endpoint having the same topic information as the second endpoint and transmits information about the second endpoint to the first endpoint.

9. A method for endpoint discovery based on the Data Distribution Service, the method comprising:
-
collecting and storing first discovery information about a first domain network in which a plurality of endpoints comprising a first endpoint are interconnected; collecting and storing second discovery information about the first domain network after a preset period of time after collecting the first discovery information; detecting a second endpoint that is added or deleted from the first domain network by comparing the first discovery information and the second discovery information; transmitting information about the second endpoint to the first domain network when the second endpoint is detected; and discovering the first endpoint having the same topic information as the second endpoint and transmitting the information about the second endpoint to the discovered first endpoint, wherein the discovery information collecting part collects location information of the topic name nodes at the lowest layer of the tree structure. - View Dependent Claims (10, 11, 12)
