一种分布式网络中多路径发送控制方法、及系统A method and system for controlling multi-path transmission in a distributed network

技术领域technical field

本发明涉及一种通信技术领域，尤其是一种分布式网络中多路径发送控制方法、及系统。The invention relates to the technical field of communication, in particular to a method and system for controlling multi-path transmission in a distributed network.

背景技术Background technique

演进的分组系统(Evolved Packet System，EPS)是第三代合作伙伴计划(3rdGeneration Partnership Project，3GPP)中出现的概念。可以认为EPS＝UE(UserEquipment，用户设备)+LTE(Long Term Evolution，长期演进；是4G接入网部分)+EPC(Evolved Packet Core，演进的分组核心网)。The Evolved Packet System (Evolved Packet System, EPS) is a concept emerging from the 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP). It can be considered that EPS=UE (User Equipment, user equipment) + LTE (Long Term Evolution, long-term evolution; part of the 4G access network) + EPC (Evolved Packet Core, evolved packet core network).

随着互联网的飞速发展，终端设备通常会具有多个网络接口，如Wi-Fi(Wireless-Fidelity，无线保真)接口、2G(The 2nd Generation Mobile Communication Technology，第二代移动通信技术)接口、3G(The 3rd Generation Mobile CommunicationTechnology，第三代移动通信技术)接口等等，从而可以实现到目标节点的多条链路。With the rapid development of the Internet, terminal devices usually have multiple network interfaces, such as Wi-Fi (Wireless-Fidelity, wireless fidelity) interface, 2G (The 2nd Generation Mobile Communication Technology, second-generation mobile communication technology) interface, 3G (The 3rd Generation Mobile Communication Technology, third-generation mobile communication technology) interface, etc., so that multiple links to the target node can be realized.

TCP(Transmission Control Protocol传输控制协议)是一种面向连接的、可靠的、基于字节流的传输层通信协议，是一对一的传输协议，不能够充分利用用户设备的多址多网络接口的优势，从而造成资源浪费。TCP (Transmission Control Protocol) is a connection-oriented, reliable, and byte-stream-based transport layer communication protocol. advantage, resulting in a waste of resources.

MPTCP(MultiPath TCP，多路径传输控制协议)是一种TCP的改进协议，它允许通信双方同时通过多条连接进行数据传送。在移动通信中，支持MPTCP技术的UE和服务器同时使用3GPP接入技术的多条连接与对端通信时，UE根据业务需求需要修改承载的QoS(Qualityof Service，服务质量)。MPTCP (MultiPath TCP, Multipath Transmission Control Protocol) is an improved protocol of TCP, which allows both communicating parties to transmit data through multiple connections at the same time. In mobile communication, when a UE supporting MPTCP technology and a server use multiple connections of 3GPP access technology to communicate with the opposite end at the same time, the UE needs to modify the QoS (Quality of Service, Quality of Service) of the bearer according to business requirements.

然而，在目前针对每一条连接根据业务需求修改各条连接的承载QoS。会造成UE及服务器的信令处理数量的增多，消耗额外资源。However, at present, the bearer QoS of each connection is modified according to service requirements for each connection. It will cause an increase in the number of signaling processes of the UE and the server, and consume additional resources.

具体实施方式Detailed ways

下面结合附图对本发明的具体实施方式作进一步说明：The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部份实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

本发明实施例提供了一种分布式网络中多路径发送控制方法，如图1所示，该方法应用于分布式网络，在所述分布式网络中包括：服务器、终端设备、接入设备以及至少两个存储设备；所述终端设备支持在两条或者两条以上的传输子流上收发业务报文；所述方法包括：An embodiment of the present invention provides a multi-path transmission control method in a distributed network. As shown in FIG. 1, the method is applied to a distributed network, and the distributed network includes: a server, a terminal device, an access device, and At least two storage devices; the terminal device supports sending and receiving business messages on two or more transmission sub-flows; the method includes:

进一步地，所述服务器为所述分布式网络中的控制面设备，所述接入设备集成转发面功能，所述第一传输子流和所述第二传输子流使用不同的网络接口；所述方法还包括：Further, the server is a control plane device in the distributed network, the access device integrates forwarding plane functions, and the first transmission subflow and the second transmission subflow use different network interfaces; The method also includes:

在本实施例中，通过业务报文中的流标识信息确定两个传输子流之间存在关联，具体实现方案可以是两个传输子流使用相同的流标识。另外，为了使转发面设备能够区分两个子流，可以在流标识前增加子流的序号信息，例如：子流序号+流标识；服务器在识别传输子流的时候，可以截取流标识进行比对。使用该方案，可以方便后续快速转换缓冲区(Translation Lookaside Buffer，TLB)表项的比对。In this embodiment, the association between the two transmission sub-flows is determined through the flow identification information in the service message. A specific implementation solution may be that the two transmission sub-flows use the same flow identification. In addition, in order to enable the forwarding plane device to distinguish between two sub-flows, the sequence number information of the sub-flow can be added before the flow identifier, for example: sub-flow sequence number + flow identifier; when the server identifies the transmission sub-flow, it can intercept the flow identifier for comparison . Using this solution can facilitate the comparison of subsequent fast translation buffer (Translation Lookaside Buffer, TLB) entries.

在本实施例中，服务器确定了传输子流之间的关联关系，那么在确定关联关系后，如果要调整该终端设备的占用的资源情况，那么可以仅修改其中一条传输子流占用的资源就可以了，可以不需要单独调整每一条传输子流，因此可以大幅降低控制面信令的开销。In this embodiment, the server determines the association relationship between the transmission sub-streams. After the association relationship is determined, if the resources occupied by the terminal device need to be adjusted, then only one of the transmission sub-streams can be modified. That's right, there is no need to individually adjust each transmission subflow, so the signaling overhead of the control plane can be greatly reduced.

进一步地，如图2所示，所述接入设备包括：Further, as shown in Figure 2, the access device includes:

第一基站和第二基站；a first base station and a second base station;

所述依据服务质量策略向所述接入设备发送修改策略包括：The sending the modified policy to the access device according to the quality of service policy includes:

在本实施例中，基站一方面作为接入设备使用一方面又兼具了转发面设备，基站转发的业务报文可以经过控制面设备，也可以处于控制面设备的监控范围内。In this embodiment, the base station is used as an access device and also serves as a forwarding plane device. The service packets forwarded by the base station can pass through the control plane device or be within the monitoring range of the control plane device.

在本实施例中，所述服务器确定传输子流之间的关联的实现方案，可以具体如下：In this embodiment, the implementation scheme for the server to determine the association between the transmission sub-streams may be specifically as follows:

所述第一基站和所述第二基站在接收到业务报文后，解析业务报文获得其中携带的流标识信息，若解析获得的流标识信息与之前的流标识信息不同，则上报给所述服务器；After the first base station and the second base station receive the service message, they analyze the service message to obtain the flow identification information carried therein, and if the flow identification information obtained through analysis is different from the previous flow identification information, report to the said server;

进一步地，本发明实施例还提供了由存储设备向同一终端设备发送业务数据的实现方案，需要说明的是，该实现方案中下行数据包仅需要是发往同一终端设备的就可以，不需要必须属于同一业务的数据包，具体如下：所述方法还包括：Furthermore, the embodiment of the present invention also provides an implementation scheme in which the storage device sends service data to the same terminal equipment. It should be noted that in this implementation scheme, the downlink data packets only need to be sent to the same terminal equipment, and there The data packets that must belong to the same business are as follows: the method also includes:

在本实施例中，由服务器控制子流的建立，在终端设备支持多种传输路径的情况下，建立了多条传输子流，由接入设备确定自身下行网络资源的占用情况，上报给控制面的服务器，由服务器调整某一个特定终端设备的其中一条传输子流的下行网络资源，不必要对该终端设备的每一条传输子流都进行策略修改，因此可以节省控制信令资源，并且在满足终端设备业务需求的前提下，非常灵活的适应不同接入设备的资源占用情况。In this embodiment, the establishment of the sub-flow is controlled by the server. When the terminal device supports multiple transmission paths, multiple transmission sub-flows are established, and the access device determines the occupancy of its own downlink network resources and reports it to the controller. The server adjusts the downlink network resources of one of the transmission sub-flows of a specific terminal device. It is not necessary to modify the policy of each transmission sub-flow of the terminal device, so it can save control signaling resources, and in Under the premise of meeting the service requirements of terminal equipment, it is very flexible to adapt to the resource occupation of different access equipment.
