摘要： One particular time divisional function (TDF) system uses both contention based and time division based access for acquisition of an uplink channel in order to support data and sporadic user controlling messages over a cable access network. One system uses a hybrid time slot in a TDF superframe of time slots to allow TDF Stations operating in contention base time slot. One particular implementation includes using a frame structure (2600) for communication. The frame structure supports at least two communication modes. The communication modes include a time division mode in which a slot in the frame structure is reserved for a device and a contention-based mode in which a contention slot in the frame structure is used by multiple devices for data communication.

摘要： An implementation provides sporadic uplink traffic transmission in a data over fixed line environment. A polling time slot can be added to the TDF superframe and can enable an access point to poll stations to determine whether an uplink channel for supporting sporadic user controlling messages (e.g., video on demand) over a cable access network. Such an implementation may eliminate the need for the TDF stations (STAs) to register with and request an uplink channel to the access point for receiving the sporadic user controlling messages. In an implementation, a frame structure (2100) is used for communication. The frame structure supports at least two communication modes. The communication modes include a time division mode in which a slot in the frame structure is reserved for a device and a polling mode in which a polling slot in the frame structure is used by multiple devices for data communication.

摘要： Without limiting the disclosure, at least one described implementation encapsulates Ethernet data for communication over a cable medium using a TDF structure typical of wireless systems. One encapsulation process receives (1130, 1820) a packet from a first source and a packet from a second source. The two packets have a particular format. The encapsulation process encapsulates (1150, 1850) the two packets into an encapsulated packet having a different format. One extraction process receives (1620, 1920) an encapsulated packet having a given format. The encapsulated packet includes a packet from a first source and a packet from a second source, with the two packets having a format different from the given format. The extraction process extracts (1630, 1930) the two packets from the encapsulated packet. A corresponding signal, as well as apparatuses, for use with the encapsulation and extraction processes are also described.

摘要： Disclosed is a system and method for providing a transparent proxy for Internet communications. A filtering and redirection module receives IP requests from at least one client (520), reads and saves the destination of the IP requests (530), and rewrites the destination of the IP request to the destination of a proxy module. Upon being unable to read, or otherwise determine, a destination for an IP request (550), the proxy module accesses destination information about the IP request from the filtering and redirection module (560). The proxy module then transmits the IP request to a web server at the original destination (580).

摘要： The invention provides a method for a web browser based remote administration system to maintain its security by utilizing an ActiveX control or a plug-in, without relying on HTTPS protection to transact management information. The invention does not burden the embedded system and thus is ideally suited for the remote administration of embedded systems. The invention provides a method to calculate a security code base upon identical algorithms in the administrative system having the browser and the embedded system. When the browser-based administrator submits the management information, an operator packages the control information as a string and invokes the security function in the plug-in with the string as a parameter. After the security function returns the result, the operator sends the form data together with a coded digest to the remote system. The digest may be embedded in the form data, for example, as a hidden field.
