Problems solved by technology

[0014] Literature [2-4] proposed network architecture elements and solutions for bandwidth aggregation and link fault mitigation based on multi-carrier mobile relay, and demonstrated the technical effect in low-speed scenarios (such as buses), but in high-speed On roads, even on high-speed rail, the speed can reach 350 km / h, resulting in a network switch or network interruption within at least 10 seconds, greatly reducing network throughput and resulting in an extremely unfriendly user experience
[0015] In summary, it is necessary to solve the poor quality of user experience QoE caused by frequent switching or interruption of the network in the existing technology when the user is moving, and the existing multi-path transmission protocol MPTCP cannot be compatible with large-scale deployment of network middleware Compatible, so it is impossible to use the bandwidth aggregation gain brought by multipath in the existing network environment

Embodiment 1

[0063] Aiming at the deficiencies of the prior art, the present invention provides an intermediate device supporting multi-channel aggregation communication, which is used to be deployed on the communication paths between multiple first communication hosts 100 and multiple second communication hosts 400 . Preferably, the middleware provided by this embodiment is compatible with the network middleware deployed on a large scale in the existing network, that is, no modification of the kernel, no modification of the upper layer application or network layer protocol is required.

[0064] Preferably, the intermediate device at least includes: a communication module 201 , an interface module 202 and a processing module 203 . The communication module 201 is used for receiving and sending data of the first communication host 100 or the second communication host 400 . The interface module 202 is used for accessing multiple networks including at least two communication paths 500 independ...

Embodiment 2

[0074] This embodiment provides an intermediate device supporting multipath communication, which is used for deployment in a mobile usage scenario. Preferably, the mobile usage scenarios may be application scenarios such as subways, trains, bullet trains, buses, and automobiles. Preferably, most user equipment (User Equipment, UE), home gateways, and routers in the prior art have limited ability to support access to multiple networks based on cost and application scenarios. For example, the UE in the prior art Considering the cost, smart phones only support dual-card dual-standby. Two SIM cards share a set of radio frequency (Radio Frequency, RF) and a set of modems, which cannot realize the simultaneous use of two standard mobile networks, and can only use Wi-Fi and One standard mobile communication network, so in special application scenarios, such as subways, trains, bullet trains, buses, cars and other application scenarios without Wi-Fi network signals, users can only use...

Abstract

The invention relates to an intermediate device supporting multipath aggregation communication, which is used for being deployed on communication paths of a plurality of first communication hosts anda plurality of second communication hosts, and at least comprises a communication module, an interface module and a processing module; the processing module is configured as follows: data of the firstcommunication host or the second communication host received by the communication module is shunted to a first path used for bypassing a kernel network protocol stack for processing data belonging toa specific data type and directly transmitting the data to a user space, and a second path for returning data not belonging to the specific data type to the kernel network protocol stack, multi-pathconnection is established with equipment or agents which are deployed on the first communication host side or the second communication host side and have multi-path transmission capability in a mode of mapping the data of the first path to at least two mutually independent communication paths.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an intermediate device supporting multi-channel aggregation communication. Background technique [0002] With the continuous development of electronic information technology, smart devices equipped with multiple network interfaces can be seen everywhere. Since the traditional TCP / IP network architecture only allows communication on a single interface, the resources of multiple interfaces are not fully utilized. In order to change this status quo, multi-path transmission technology emerges as the times require. [0003] Multipath Transport Control Protocol (MPTCP) is a transport layer protocol that uses multiple paths for concurrent transmission, which can improve end-to-end throughput and increase network utilization and redundancy. MPTCP is fully compatible with the Transmission Control Protocol (Transport Control Protocol, TCP). On the basis of TCP, a new TCP option he...
