摘要： A computer implemented method monitors resource usage of a virtual machine. When a virtual machine is instantiated, resource usage of the virtual machine is monitored to form monitoring data. The monitoring is performed externally from the virtual machine. When the virtual machine is later suspended, the monitoring data is stored as metadata associated with the virtual machine.

摘要： Methods and apparatus are provided for recovering from packet loss in an end-to-end network connection having at least one wireless segment. A packet on a wireless segment of an end-to-end network connection is processed by determining whether the packet comprises one or more of a lost packet and a malformed packet; and generating a modified packet for an application associated with the packet to replace one or more of the lost packet and the malformed packet if the application is substantially tolerant to one or more of lost and malformed data. The modified packet comprises, for example, a non-original packet and/or a corrected packet. Link layer information or information from a deep packet inspection can be used to determine whether the packet comprises a lost packet or a malformed packet.

摘要： A method, system and computer program product for creating a customized message in a video-on-demand service, in which a user accesses the service using a communications device. In an embodiment, the method comprises using a video-on-demand server to intercept the access by the user of the video-on-demand service, obtain information about video content of a local cache of the video-on-demand service, obtain a profile of the user, and identify a context of the user. A customized message is constructed for the communications device based on the information about the local cache, the profile of the user, and the context of the user. The video-on-demand server sends the customized message to the communications device. In one embodiment, the user accesses the video-on-demand service through an edge base station of a core network, and the video-on-demand server is in this base station of the core network.

摘要： Network management data is managed by determining that a first version and a second version of a set of network management data have been created. The set of network management data is associated with a plurality of managed entities in a network. First and second network graphs are created based on the first version and second version of the set of network management data, respectively. The first and second network graphs include a first and second set of entities in the plurality of managed entities, respectively. A similarity metric is assigned between at least one or more entities in the first and second set of entities. At least a first entity in the first set of entities and at least a second entity in the second set of entities are determined to be identical entities based on the similarity metric being one of equal to and above a first given threshold.

摘要： Methods and apparatus are provided for performing byte caching using a chunk size based on the object type of the object being cached. Byte caching is performed by receiving at least one data packet from at least one network node; extracting at least one data object from the at least one data packet; identifying an object type associated with the at least one data packet; determining a chunk size associated with the object type; and storing at least a portion of the at least one data packet in a byte cache based on the determined chunk size. The chunk size of the object type can be determined, for example, by evaluating one or more additional criteria, such as network conditions and object size. The object type may be, for example, an image object type; an audio object type; a video object type; and a text object type.

摘要： Methods for inserting a middlebox into a network connection include monitoring network state information in a connection between a client and a server. When the connection is idle, a connection entry is created for each device and is initialized using state information gathered by monitoring the network connection. Redirection of the network connection is activated between the client and the server such that the middlebox mediates the connection. Methods for removing a middlebox from a network connection include determining a degree of mismatch between a sequence number in a first connection between the middlebox and a client and a sequence number in a second connection between the middlebox and a server, delaying acknowledgment signals from the middlebox on a connection to decrease the degree of mismatch, and establishing a direct connection between the client and the server without mediation by the middlebox when the degree of mismatch is zero.

摘要： A method, system and computer program product for managing content distribution in a mobile communications environment. The communications environment includes a core network and a multitude of end-user devices. In one embodiment, the method comprises downloading content from the core network to the end-user devices; and maintaining a map between the end-user devices, the content downloaded to the end-user devices, and the locations of the end-user devices. When a first of the end-user devices requests a specified content, this map and one or more rules are used to identify a second of the end-user devices having the specified content. The first of the end-user devices fetches the specified content from this identified second of the end-user devices. In one embodiment, object location descriptors embedded in the content are rewritten when the content is downloaded to the end-user devices.
