摘要： This disclosure relates to managing voice-based data communications within a clustered network environment using application-layer functionality, and more particularly to a primary network device within a cluster that manages transmissions related to a communication and synchronizes state information associated with the communication to other network devices within the cluster. One exemplary method includes receiving, by a network device in a cluster, information associated with a data communication between a first user device and a second user device, and analyzing, by the network device, the received information using application-layer functionality to identify a primary network device that manages the data communication. When the network device is not the primary network device, the network device forwards the received information to the primary network device. Upon receipt of the information, the primary network device provides updated state information for the communication with other network devices within the cluster for synchronization purposes.

摘要： In general, techniques are described for performing session layer pinhole management within a network security device. In accordance with the techniques, the network device includes a resource manager module and a Session Initiation Protocol (SIP) module. The SIP module receives a SIP message from a private server, the SIP message requesting a SIP session. In response to the SIP message, the SIP module via the resource manager module opens a pinhole to permit the SIP session and assigns via the resource manager module resources included within the resource pool to monitor each call occurring over the SIP session. The SIP module further determines whether each of the calls has completed based on an session layer characteristic of a subsequent SIP message associated with each call and based on the determination, returns via the resource manager module the resources assigned to monitor each completed call to the resource pool.

摘要： A method implemented by an agent operating on a mobile device communicating to a cloud-based system includes opening up local listening sockets on the mobile device; redirecting outgoing traffic from all application on the mobile device except the agent to the local listening sockets; and forwarding the outgoing traffic from the local listening sockets to the cloud-based system with additional information included therein for the cloud-based system.

摘要： Systems, apparatus, methods, and computer program products for multicast access control are provided to analyze incoming data based on a source zone and a destination zone of the incoming data. Appropriate access control rules are applied to incoming data based on the results of the analysis. Additional implementations of a multicast access control include using a proxy rendezvous point operable to function as a rendezvous point in place of a physical rendezvous point.
