Embodiment 1

[0099] Embodiment 1, referring to Fig. 2. Fig. 2 shows a network communication system 001 of an exemplary embodiment. The network communication system 001 includes, but is not limited to, at least two network nodes 501 and 502, which are the sending side and the receiving side, and they are connected to any network device in the world through various network links in different forms, including but not limited to PPP links, RAIN devices, bridges, switches, routers, etc., and combinations including at least one of the above. The network communication system 001 can be used for various communication protocols, including but not limited to IPX / SPX, TCP / IP, X.25, AppleTalk, PPP, SLIP, PLIP, etc., and combinations including at least one of the above items. Each sender network node 501 and / or recipient network node 502 may be a general purpose computer and include operating system software and any other various kinds of applications. Those skilled in the art should understand that...

Embodiment 2

[0101] Embodiment 2, refer to Fig. 9 again. Fig. 9 shows a flow of data communication between a sender and a receiver in an exemplary embodiment. The sender network node 501 establishes a communication line with the receiver network node 502 through the network communication system 001, and the sender network node 501 communicates with the receiver network node 502 through a standard Network protocols establish a virtual communication path. In this path, data packets 531 encapsulated with various protocols (or multi-packet data packets 532 obtained by splitting the data packets 531 ) can be carried. Through the RAIN device network link 510, the extra bandwidth brought by multi-link integration is realized, and the encryption function is implemented for the data packet 531 or data packet 532, which is allocated according to the application type of the data packet 531 or data packet 532 Bandwidth, which enables last-come-first-come (QOS) of data packets. Therefore, it should ...

Embodiment 3， pic 3。 Embodiment Embodiment ， 1 510 1 specific Embodiment approach 002

[0102] Embodiment 3, see Fig. 3. This embodiment is based on the above embodiments, and further describes a specific implementation manner 002 of the cheap redundant network array device 510, that is, the cheap redundant network array device includes:

[0103] The upper-layer user application 521 is logically connected to the cheap redundant network array device 510 in the RAIN system equipment. Computer technicians should understand that the computer equipment carrying the upper-layer user application 521 can be connected to the cheap redundant network array equipment in the RAIN system equipment through the physical interface of the equipment. The network array device 510 is physically connected, and then logically connected with the core program of the RAIN device 510 running in the RAIN system device through the device driver interface of the operating system running on the computer device. The user application can communicate with the RAIN device 510 in the RAIN system de...

Abstract

The equipment part of this system includes at least a data sending net point, a data receiving net, a net link, RAIN device and a transferring net communicating between them. The RAIN device consists of 2 / 4 / 8 pieces of PPP physical link I / O ports, the processing branch, the stack branch, the exchanging part and the low cost redundancy net array comm. protocol. The method part of this system discloses practical steps to increase the bandwidth. It can be applied in numerous nets. Without the support of the accessing end, it piles efficiently up the bandwidth, manages the link and possesses efficient toleration ability. On the basis of the protocol, this system suits various business requirements and adds functions, such as the abnormal processing, authentication, encryption and QOS. Its practicability and reliability are good and it costs low.

Description

technical field [0001] The invention relates to a network terminal device which increases the network bandwidth of the communication switching technology and enables it to have fault-tolerant processing capability and a method for increasing the bandwidth by using the device. Background technique [0002] In the current network environment, multi-link integration is usually implemented to increase network bandwidth by using No. 1 multi-channel technology or MLPPP technology similar to ISDN. [0003] There are two main types of ISDN: Basic Rate (BRI) and Primary Rate (PRI). The telecommunications bureau provides BRI interfaces to ordinary users, using the original twisted pair, and the rate can reach 144Kbps. BRIISDN can provide two B channels (64K each) and one D channel (16K) on a pair of twisted pairs. The D channel is used to transmit signaling, and the B channel is used to transmit voice and data. One phone call only occupies one B channel, so multiple businesses or co...
