Abstract: There is provided a method performed by a device in a network camera system. First and second encoded image data representing the same scene are received (S02, SO4) over a network. The first and the second encoded image data are collected under the same light condition, albeit using different camera parameters. In particular, the second encoded image data is collected using camera parameters which simulate that the second encoded image data is collected under a darker light condition. A ratio of received data amount per time unit of the first encoded image data to received data amount per time unit of the second encoded image data is determined (S06) and the ratio is then used (S08) as an indication of a level of noise in the first encoded image data.

Abstract: A computer device includes logic configured to implement a tunnel broker. The tunnel broker is configured to receive a request from a client device for a service in a system, the service having a requested service property; select a first node in the system that hosts a first service instance having the requested service property; and establish a communication tunnel with a first end at the client device and a second end at the selected first node. The tunnel broker is further configured to determine that the first node no longer hosts the first service instance having the requested service property or that the first node has become unreachable; select a second node in the system that hosts a second service instance having the requested service property; and move the second end of the communication tunnel from the first node to the second node.

Abstract: A method and system for finding services in a service-oriented architecture network may include receiving, in a local service registry from a client, a search query for a particular service. The local service registry may include a local database listing registered services. The network may include querying the local database to determine a first list of services that satisfy the search query and determining a neighboring service registry, in a network of service registries, based on a property other than a property of the particular service being searched for. The method may include sending the search query to the neighboring service registry and receiving, from the neighboring service registry, a second list of services, registered with the neighboring service registry, that satisfy the search query. The method may include returning, to the client, the first list of services and the second list of services that satisfy the search query.

Abstract translation: 用于在面向服务的架构网络中查找服务的方法和系统可以包括在来自客户端的本地服务注册表中接收针对特定服务的搜索查询。 本地服务注册表可以包括列出注册服务的本地数据库。 该网络可以包括查询本地数据库，以基于除了正在搜索的特定服务的属性之外的属性来确定在服务注册表的网络中满足搜索查询并确定邻近服务注册表的服务的第一列表。 该方法可以包括将搜索查询发送到相邻服务注册表，并从邻近服务注册表接收满足搜索查询的向相邻服务注册表注册的第二服务列表。 该方法可以包括向客户端返回第一服务列表和满足搜索查询的第二服务列表。
