摘要:
In peer-to-peer (P2P) communications, it has been recognized herein that various context information needs to be exchanged between peer devices (PDs) or between different layers/protocols within a peer device (PD). Various embodiments described herein address how to design effective management functions, services, and primitives for context management across and/or within different protocol layers to enable context-aware peer-to-peer communications in proximity. This disclosure proposes multiple embodiments for cross-layer context management in context-aware peer-to-peer communication in proximity. For example, embodiments described herein provide context management to efficiently enable context-aware P2P communications, such as, for example, social networks.

An SDN controller to provision network resources at a data plane to keep progressive downloads of multimedia files proportional to encoding rates is disclosed. Packets from a new or unknown flow being downloaded at a default rate are forwarded from an access point, or other device, to an SDN controller for analysis. If a progressive download of a multimedia file (e.g., a video file) in progress is detected, an encoding rate of frames for the multimedia file is determined. A target download rate for the multimedia file at the access point is determined based on the encoding rate, in an embodiment. Other optional factors also take into account network-wide data plane information gathered by the SDN controller from various points on the network. Additionally, a playback history for a particular multimedia file can affect the target download rate, based on whether, for example, a file is likely to be quickly halted.

摘要:
Method and apparatus for propagating state information updates are disclosed. In the method and apparatus, a node establishes connections with one or more nodes of a plurality of nodes based at least in part on the number of connections retained by each node of the plurality of nodes. The node may then propagate state information updates to the one or more nodes.

Techniques are provided for implementing a zone-based firewall policy. At a virtual network device, information is defined and stored that represents a security management zone for a virtual firewall policy comprising one or more common attributes of applications associated with the security zone. Information representing a firewall rule for the security zone is defined and comprises first conditions for matching common attributes of applications associated with the security zone and an action to be performed on application traffic. Parameters associated with the application traffic are received that are associated with properly provisioned virtual machines. A determination is made whether the application traffic parameters satisfy the conditions of the firewall rule and in response to determining that the conditions are satisfied, the action is performed.
