Systems and methods for establishing a KVM session are disclosed. The KVM session is designed to provide a communication channel between a client device and a target device without the use of an appliance. For example, the KVM session includes a virtualized KVM session in which the hardware and software used to create the communication channel are stored on a network-based device, as opposed to a multi-port appliance physically connected to the target device. A virtual KVM session eliminates the need for the target device to have a-priori knowledge related to the client device. The virtual KVM session can individually communicate with the client device and the target device, and negotiate a session between the client device and the target device prior to any communication between the target device and the client device. In some embodiments, the virtual KVM session uses out-of-band signaling and SIP to negotiate a session.

The present disclosure provides a method for generating a code by a digital photo frame. The method including receiving, from the terminal and by a controller of the digital photo frame, a request for connecting the terminal to the digital photo frame; and generating, by the controller of the digital photo frame, a code according to authorization information of the digital photo frame, wherein a server issuing the authorization information of the digital photo frame does not generate the code. The present disclosure also provides a method for transmitting photos or videos between a terminal and a digital photo frame, the method comprising: receiving a request for transmitting the photos or the videos; determining whether the digital photo frame and the terminal use a same WLAN; and instructing the terminal or the digital photo frame to transmit the photos or the videos via the WLAN.

Disclosed are various examples for providing network content filtering to client devices on a per-application basis. A network stack receives a request from an application to connect to a network service. The network stack then determines the identity of the application. Based at least in part on the identity of the application, the network stack initiates a network connection between the application and the network service using or without using a managed network tunnel.

A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The tunnel device is selected based on an attribute, such as IP Geolocation. A tunnel bank server stores a list of available tunnels that may be used, associated with values of various attribute types. The tunnel devices initiate communication with the tunnel bank server, and stays connected to it, for allowing a communication session initiated by the tunnel bank server. Upon receiving a request from a client to a content and for specific attribute types and values, a tunnel is selected by the tunnel bank server, and is used as a tunnel for retrieving the required content from the web server, using standard protocol such as SOCKS, WebSocket or HTTP Proxy. The client only communicates with a super proxy server that manages the content fetching scheme.

Some embodiments relate to a method implemented by a first terminal for setting up a session with a second terminal. An identifier of a session server is obtained at least from a subscriber device in the first terminal which comprises a subscriber identifier and an operator identifier. A session request and an identifier of the second terminal are sent to the server. At least one instruction is received from the server and a message comprising a first set, relative to the first terminal, of at least one characteristic parameter of the requested session is generated in accordance with at least one instruction received and sent to the server. A message is received from the server comprising a second set of at least one characteristic parameter of the requested session, the second set relating to the second terminal and having a non-zero overlap with the first set.
