Abstract

A plug and play scheme for IP based devices includes establishing an infrastructure in the Internet so that the IP based devices can plug and play in the existing or oncoming Ethernet network. Through the Dynamic IP and the Internet, a visitor can connect with an IP based device via the infrastructure and the information can be sent or received without going through servers so that the data traffic in the Internet will be reduced. Additionally, with a plurality of the bridge servers being backed up with each other, the transmission quality can be ensured by means of automatic data transmission through the bridge servers if the connection between the visitor and the IP based device breaks. Furthermore, the infrastructure includes several failover ways to ensure the link between the visitor and the IP based device and reduce the risk of losing connection in the Internet.

Description

Title: Plug and Play Scheme for IP Based Devices and Their Failover
Schemes for Quality of Services
Field of the Invention
The present invention relates to a plug and play scheme and quality of service for IP (internet Protocol) based devices and their failover schemes, and particularly, to one in a Globally centrally hosted server system to reduce data traffic by means of the Internet and Dynamic IP.
Description of the Prior Art
With the progress and development in the present times, more and more equipments are used in daily lives. Moreover, with the rapid development and the maturation in computer technology and the Internet, it not only dramatically shortens the distance among people but also makes it possible to connect with various equipments in a plurality of remote sites.
A conventional centrally hosted server system, such as a centrally managed Internet image system 2 as shown in Fig. 5, comprises a host 21 and a plurality of cameras 22 that receive the information about image and sound and then send it to the host 21 to be saved or sent to the visitors in real time. Any user who wants to browse the information has to download it first from the host 21. Thus, the information is downloaded or uploaded all through the host 21 and within the same period of time the greater amount of the information is, the greater load the host will take. Resultantly, the jam in the Internet will occur if there is no greater capacity to handle the increasing data traffic and it will further lead to slow transmission speed and longer duration of time. However, if the cameras 22 can be connected with the terminal ends of visitors 23 pier to pier, the load of the host 21 will be reduced to achieve the best transmission state for information, In this example above, the host 21 exists independently so that if it malfunctions, the terminal ends of visitors 23 will fail to receive the information about ünage and sound from the cameras 22 and it will bring inconvenience and loss to visitors. Thus, for many present corporations, it is necessaiy to provide visitors with the Internet of high availability and constant connectivity.
It is usually impossible to obtain the exact IP addresses for all devices in the Internet to connect with each other pier to pier just because most visitors are in connection with the Internet by dynamic IP addresses provided by PPPoE or DHCP (Dynamic Host Configuration Protocol). Besides, in most present ISP corporations, the service of providing fixed IP addresses is more expensive than that of providing dynamic IP addresses. Hence, without a proper transmission mechanism in this example above, the pier-to-pier connection between the terminal ends of visitors 23 and the cameras 22 can work only when the two ends own fixed IP addresses, and this will increase the cost of the visitors. Additionally, the visitors will fail to get important information and thus suffer great loss if they cannot receive the information from the cameras 22 through the wired Internet at any moment.
Routers solve the problem about IP sharing. However, it is necessary to set the function of switching addresses before the IP based devices are in connection with routers, and thus it is very inconvenient. Therefore, the present invention provides a plug and play scheme for IP based devices and their failover schemes. The scheme makes possible the pier-to-pier connection between browsing devices and plug and play devices through any slave server under the failover to bring high availability and constant connectivity of the Internet to the visitors.
Summary of the Invention
The main objective of the present invention is to provide a plug and play scheme for IP based devices and their failover schemes wherein the IP based devices can be plug and play in the present or connected Internet.
The second objective of the present invention is to provide a plug and play scheme for IP based devices and their failover schemes wherein the IP based devices can be plug and play in the present or oncoming Internet and the visitors can connect with that devices easily.
The third objective of the present invention is to provide a plug and play scheme for IP based devices and their failover schemes wherein the visitors can directly connect to the IP based devices without going to through the central server so that the quality of the information transmission will be improved and the data traffic in the Internet will be reduced.
The fourth objective of the present invention is to provide a plug and play scheme for IP based devices and their failover schemes by which the IP based devices can be connected with each other smoothly.
To achieve the objectives mentioned above, the present invention comprises a centrally hosted server system wherein all the elements can be connected with each other to receive or send information and that system is composted of a master/slave server configuration, a plurality of IP based devices, and a plurality of visitors; the master/slave server configuration including a master server and a plurality of slave servers, and the master server can be backup by mirrors at the same site or remote sites of master server to insure the function of the master server.
The IP based device with a dynamic IP address constantly sends a registration package to a specific slave server of the system and meantime failovers to other slave servers. If the registration fails the device turns to register at other slave servers.
When the registered slave server receives the registration information, it will mirror the information to all the other slave servers.
The visitors should be the devices able to connect with the Internet. Besides, the visitors should connect with a specific slave server in the system and meantime failover to other slave servers so that they can visit the IP based devices. If the first connection with the pre-assigned slave server fails, it will turn to connect with other ones.
The server used by a visitor will inform the specific slave server about the visitor's IP information.
The IP based device sends a package back to the visitor so that the visitor can connect directly with the IP based device.
Thus, the visitor can exchange mfonnation with the IP based device without going to through any of the slave servers.
Moreover, the present invention has a plurality of bridge servers through which the information can be communicated constantly between the visitor and the IF based device if their connection fails.
Furthermore, the present invention provides a broadcasting and mutual agreement between the visitor and the IP based device so that their connection in a local network can work without going to through the Internet.
The present invention will be apparent after reading the detailed description of the preferred embodiment in reference to the accompanying drawings.

A plurality of the IP based devices (121,122,1 2n) is connected with a router 124 and the Internet through a modem. The router 124 can be, but not limited to, the Hub, the Ethernet Switch or the WifI Access Point; and the modem 125 can be replaced by various standards of xDSL (Digital Subscriber Line), PSTN (Public Switched Telephone Network), Cable, GPRS (General Packet Radio Service), or Xcdma (X-Code-Division Multiple Access). Besides, the IP based devices (121,122,12n) can be in direct connection with the Internet through a modem 125' by means of PPPoE.
A plurality of the I? based devices (121,122,12n) can be, but not limited to, the PC (personal computers), Pocket PC, IP phones, SetTopBox, IP Cameras, Video Gateways, or Mobile Phones. The visitors 131 can be, but not limited to, the PC, Pocket PC, I? phones, SetTopBox, IP Cameras, Video Gateways, or Mobile Phones.
The system further should be pre-installed a initialization flow procedures and a plurality of failover procedures so that the IP based devices can be plug and play and connected with other elements for the failover purpose.
Therein, the IP based device constantly sends a registration package with the mformation about IP addresses, port number, or other basic infonnation to a specific slave server in the system. While connecting with and registering at the slave server, the IP based device also failovers to other ones so that the device can register at other slave servers when the former registration fails. The registered slave server received the information of the IP based device will mirror the information to all the other slave servers. The visitor visits a specific slave server in the system and failovers to others to connect with the U' based device, and if the first connection with the pre-assigned slave server fails, the connection will be routed to other slave servers automatically. The specific slave server informs the slaver server registered by the IP based device about the information of the visitors' IP. Then the IP based device sends a package to the visitor so that the visitor can directly connect with the IP based device and meantime failover to the bridge servers; if the connection mentioned above fails, the visitor and the IP based device can exchange information with each other through the bridge servers. Referring to Fig. 2 and 3 will make apparent the connection procedures among the elements in the present invention.
SI. The IP based device registers at the slave server.
S2. The slave server registered failovers to other slave servers.
S3. S4. The visitor detects the IP based device from any slave server.
S5. The IP based device sends a package to the visitor.
S6. The visitors directly connect with the IP based devices without going to through slave servers.
S7. The visitor exchanges the information directly with the IP based device.
S8. When the connection between the visitor and the 1P based device fails, the two exchanges the information by means of the pre-assigned bridge servers instead.
S9. If the transmission through the bridge servers breaks, the information will be sent through the failover bridge servers instead.
Moreover, the bridge servers can be added to ensure the connection quality between the visitor and the IP based device.
Referring to Fig. 4, if the visitors and the IP based devices are in the same local network, the visitors can automatically detect the IP addresses of the IP based devices by means that the IF based devices broadcast and thus the devices can be plug and play in this local network. Referring still to Fig. 4, the IF based devices l21,122,12n and the visitors 131,132 are all connected with the same router 124 that can be, but not limited to, the Hub, the Ethernet Switch or the Wifi Access Point.
Whether the present invention is used in a local network or not, the IF based devices can be plug and play.
