Customer premise equipment and method of remote login

摘要

A customer premise equipment (CPE) communicates with both lower-layer and upper-layer network within the LAN that communicates with an ISP server. The CPE searches other CPEs after receiving commands from the upper-layer network and makes port configuration after receiving commands from the upper-layer network, and also configures the default telnet port according to the port number receiving from the upper-layer network. Then the CPE establishes remote communications via the default telnet port with the ISP server. Finally the CPE disabling module disables the telnet service and releases the default telnet port after receiving commands from upper-layer network.

主权项

1. A customer premise equipment (CPE) locating in a lower-layer network and an upper-layer network of a local area network (LAN) and in communication with an ISP server, each of the lower-layer network and the upper-layer network comprising other CPEs within the LAN, the CPE comprising: at least one processor; a storage system; and one or more programs that are stored in the storage system and are executed by the at least one processor, the one or more programs including: a searching module that searches other CPEs in the lower-layer network after receiving a searching command from the upper-layer network and reports a number of other CPEs managed by the ISP server in the lower-layer network to the upper-layer network after the number is validated; a configuring module that receives a port number assigned by the upper-layer network and makes port configuration after receiving a configuration command from the upper-layer network, wherein the port configuration comprises: activating telnet service of the CPE, configuring a default telnet port according to the assigned port number, assigning other port numbers to the other CPEs managed by the ISP server in the lower-layer network based on the assigned port number and the number reported, sending the port numbers assigned and configuration commands to the other CPEs managed by the ISP server in the lower-layer network; and a login module that monitors a telnet request from the upper-layer network via the default telnet port and establishes a remote communication with the ISP server via the default telnet port when a destination port of the telnet request matches with the default telnet port.
