Abstract: The present invention is to provide a method of making a router act as a relay proxy, which is applied to a network system comprising a server of an Internet service provider, at least a router, the Internet and at least two network devices, wherein the router and network devices are connected with the server through the Internet respectively. The method comprises the steps of designating the router as a relay proxy when the router receives and accepts a relay request from the server, and directing the network devices to connect to the router designated as a relay proxy respectively when the server attempts to connect the network devices which enables the network devices to communicate and proceed data access with each other through the relay proxy. Thus, the data access with each other of said network devices may be accomplished through said relay proxy instead of said server.

Abstract: A method of transmitting a real-time network image is applied to a network system having an IP camera, a NAT router, the Internet, and a server of an Internet service provider (ISP). The method includes steps of: requesting an IP address from the DHCP server by the IP camera according to a DHCP protocol when the IP camera is linked to the Internet via the NAT router; automatically logging the IP camera in the ISP server after requesting the IP address and linking to the Internet; and building up a linking channel between the IP camera and the ISP server after finishing logging. As a result, other remote electronic devices can download a real-time image captured by the IP camera through the linking channel via the Internet after logging in the ISP server.

Abstract: A method of playing real time audio and video signals via a network platform is applied to a network system, which comprises a server at an internet service provider (ISP) having a network platform comprising at least one user selectable icon corresponding to a web camera being connected to said server via internet, and comprises the steps of when said web camera is turned on and is connected to said network platform, said network platform making said icon enter a standby mode; when a computing device is connected to said server via internet and logged on to said network platform, and said icon in standby mode is clicked, said network platform establishing a connection channel between said web camera and said computing device; and transmitting audio and video signals captured by said web camera via internet and directly through said connection channel to said computing device in real time.

Abstract: An apparatus for bandwidth management of TCP traffic on a communications network that apparatus comprises a forward data controller, a backward Ack controller, and a post-acknowledgement control machine. The forward data controller has a queuing space of a plurality of buffer registers for queuing outbound data of the TCP traffic. The backward Ack controller has a plurality of queues each having a plurality of buffer registers for queuing inbound Acks of the TCP traffic. The post-acknowledgement control machine includes an Ack-pacing controller for controlling the queuing of the backward Ack controller. The Ack-pacing controller subsequently allows the release of each of the inbound Acks queued in backward Ack buckets of the backward Ack controller to the sender of the outbound data upon determining that the queues in the forward data controller is at least partially emptied by sending the queued outbound data to the receiver of the outbound data.

Abstract: Keywords: computer assisted test, test assessment, test collection, distant learning. The main problem with the network test base system is that there are neither sufficiently many nor good enough test items. To satisfy these two points, there must be more test item resources and a mechanism for assessing test items to determine whether a test item should stay in the test base. The present invention provides a method for automation of dynamic test item collection and assessment, which allows teacher and students to contribute test items to the test base and each independently managed test base can share test items. This can make the test base rapidly grow and expand the size of a test base. The more independent the student are, the higher the applicability of this method is.
