A novel method of providing virtual private access to a software defined data center (SDDC) is provided. The SDDC uses distributed VPN tunneling to allow external access to application services hosted in the SDDC. The SDDC includes host machines for providing computing and networking resources and a VPN gateway for providing external access to those resources. The host machines that host the VMs running the applications that VPN clients are interested in connecting performs the VPN encryption and decryption. The VPN gateway does not perform any encryption and decryption operations. The packet structure is such that the VPN gateway can read the IP address of the VM without decrypting the packet.

Embodiments of the present invention provide a system for intelligent processing, routing, and distributing electronic resource requests. In particular, the system may be configured to receive an electronic resource request from a user device of a user, in response to receiving the electronic resource request, establish a communication link with one or more channels, extract real-time data associated with processing of the electronic resource request from the one or more channels, and aggregate the real-time data to process the electronic resource request

A network element of an Internet Protocol multimedia subsystem buffers network resource usage information in the cloud. After generating network resource usage information based on an observation of network resource usage, the network element transmits the network resource usage information to a cloud-based storage service for buffering. Once a network resource usage collection function is available, the network element retrieves the network resource usage information from the cloud-based storage service and transmits it to a charging collection function for generation of call detail records.

In an embodiment, a source node assigns a first number to a probe data packet in a probe data flow in a sending sequence, where the first number is used to select a transmission path for the probe data packet. The source node sends the probe data packet in the probe data flow to a destination node at a first sending rate. Each time the source node receives a probe data packet backhauled by the destination node, the source node sends a service data packet in a service data flow, where the service data packet is assigned a second number corresponding to the probe data packet, and the second number is used to select a transmission path for the service data packet.

In some embodiments, a method receives a packet for a flow from a first application in a first workload to a second application in a second workload. The packet includes an inner header that includes layer 4 information for the first application. The method determines if a setting indicates an outer source port in an outer header should be generated using layer 4 information from the inner header. The setting is based on an analysis of packet types in the flow to determine if fragmented packets are sent. When the setting indicates the outer source port in the outer header should be generated using layer 4 information from the inner header, the method generates the outer source port using the layer 4 information for the first application from the inner header. The packet is encapsulated using the outer header, wherein the outer header includes the outer source port.

While presenting on a display apparatus videos of high picture quality obtained from portable video processing apparatuses such as a camera and a cellular, it is possible to communicate with the Internet and/or a home network. A display apparatus includes a first radio communication unit capable of receiving video information by radio from an external video processing apparatus, a second radio communication unit capable of connecting by radio to a network, and a control unit for controlling assignment of connection by radio transmission for each of the first and second radio communication units. The control unit assigns connection of the first radio communication unit with higher priority and controls the assignment of the transmission rate such that the transmission rate between the first radio communication unit and the external video processing apparatus is more than that between the second radio communication unit and the network.
