A URL verification service is provided that is used to evaluate the trustworthiness of universal resource locators (URLs). As a user browses the world wide web, a URL verification client captures a URL associated with a web page of unknown authenticity. The URL verification client transmits the captured URL to a URL verification server. The URL verification server compares the URL to actively maintained whitelist and blacklist information. The server also uses the URL and a user-supplied or automatically-extracted brand to query a search engine. The URL verification server processes the response of the search engine to the search engine queries and the results of cache and whitelist and blacklist comparisons to determine whether the captured URL is legitimately associated with the brand. The results of the URL evaluation process are transmitted from the URL verification server to the URL verification client, which notifies user.

Environmental conditions, such as temperature or wind load, may cause a fiber-optic link to expand or contract, resulting in upstream communications drift. Current methods compensate for such drift assuming it is caused by environmental conditions; however, these methods cannot determine abnormal behavior due to fiber faults that magnify the effect of environmental changes. An example embodiment of the invention provides a method and corresponding apparatus for detecting abnormal drift behavior in a passive optical network (PON) and may include monitoring a metric representative of drift of upstream communications for an optical network unit (ONU) in a PON. The example method may detect and report abnormal behavior in the PON that cannot be fully attributed to “normal” environmental conditions, and indicate a possible fiber cable fault. An ability to detect fiber link faults may allow a system operator to proactively maintain the physical fiber before service interruptions affect an end-user.

The invention relates to a method used for saving node energy in a delay tolerant network and an intermittent connection network, belonging to the field of network communication technique. The method comprises the steps as follows: a source node queries a node neighbor list; if no destination node information exists, the message is temporarily memorized in a node buffer; the non-empty nodes in the buffer periodically send exploration information which is used to exchange a message list and a message delivery acknowledgement list; when the node sending the exploration information receives a return information, the buffer is actively maintained according to the message delivery acknowledgement list carried in the return information and a message is sent by the node; after an intermediate node successfully transmits the message to the destination node, the node adds corresponding records into the message delivery acknowledgement list memorized locally and deletes the message from the buffer. The method can effectively reduce the quantity of the redundant nodes, improves the performance of the whole network and prolongs the life period.
