摘要： A method for reducing congestion in a wireless communication network is presented. The method includes monitoring a congestion level of at least one network node of the network. When the congestion level is greater than a first threshold, the method includes initiating a first congestion control mechanism. When the congestion level is greater than a second threshold, the method includes initiating a second congestion control mechanism, the second threshold being greater than the first threshold. In some implementations, the first congestion control mechanism includes codec rate adaptation (CRA), and the second congestion control mechanism includes at least one of rejecting new service requests and dropping existing services. The method may include, after initiating the first congestion control mechanism, starting a timer and, when the timer reaches a pre-determined value and the congestion level is greater than the first threshold, initiating the second control mechanism.
摘要翻译：提出了一种减少无线通信网络拥塞的方法。该方法包括监视网络的至少一个网络节点的拥塞级别。当拥塞级别大于第一阈值时，该方法包括启动第一拥塞控制机制。当拥塞级别大于第二阈值时，该方法包括启动第二拥塞控制机制，第二阈值大于第一阈值。在一些实现中，第一拥塞控制机制包括编解码器速率适配（CRA），并且第二拥塞控制机制包括拒绝新服务请求和删除现有服务中的至少一个。该方法可以在启动第一拥塞控制机制之后启动定时器，并且当定时器达到预定值并且拥塞级别大于第一阈值时，启动第二控制机制。

摘要： A method, apparatus, and computer program product for indicating and responding to various congestion levels in a communication system, such as a wireless communication network. A congestion level in the network is determined, and a percentage of data packets to be transmitted to an endpoint, such as user equipment or another network endpoint serving the user, are marked to indicate the congestion level. The endpoint determines the congestion level at the network from the percentage of received data packets that are marked and may initiate an appropriate response behavior in response to the determined congestion level.

摘要： A system comprising an inter-RAT/inter-network redundancy controller (IRC) is provided. The IRC is configured to communicate with a source gateway in communication with a source radio access network (RAN) using a first radio access technology (RAT). The IRC is further configured to communicate with a target gateway in communication with a target RAN using a second RAT. The IRC is further configured to promote a handover of a user equipment from the source RAN connected to the source gateway to the target RAN connected to the target gateway when the source gateway fails.

摘要： Processes for fingerprinting a document and for preventing information leakage at a deployment point are disclosed. For fingerprinting a document, a sequence of hash values for a document is generated, a portion of said hash values to be selected as fingerprints for the document. A current window is positioned over a portion of the sequence of hash values. The hash values are examined starting from one end of the current window, and a first-encountered hash value that is 0 modulo P is selected to be a fingerprint for the current window. For information leakage prevention at a deployment point, a rolling hash calculation is performed on a target document, and a determination is made if a hash value is 0 modulo P. A first filter is applied if the hash value is 0 modulo P, and a second filter is otherwise applied. Other embodiments, aspects and features are also disclosed.

摘要： In one embodiment, a client computer is protected from phishing attacks using a sensitive state monitor and a phishing site detector. The sensitive state monitor may detect reception of a web page displayed in a web browser of the client computer. The sensitive state monitor may determine whether or not the web page is a sensitive web page, such as those used to receive user confidential information. When the sensitive state monitor determines that the web page is sensitive, the sensitive state monitor may ask the user to confirm that the web page is indeed sensitive. After user confirmation, the sensitive state monitor may invoke the phishing site detector, which may determine whether or not the website serving the web page is a phishing site.

摘要： An owner of media data encrypts the media data using a session key. The session key is encrypted using a public key of a designated recipient of the media data. A key manager provides the encrypted session key to the recipient while the owner is sharing the media data with the recipient. The encrypted media data is published and accessed by the recipient over a public computer network. The encrypted session key and the encrypted media data are received in the recipient's computer, where the encrypted session key is decrypted into the session key using the recipient's private key and the encrypted media data is decrypted into the media data using the session key. When the owner is no longer sharing the media data with the recipient, the recipient is prevented from further receiving the encrypted session key from the key manager.
