本发明涉及DDS网络。The invention relates to a DDS network.
背景技术Background technique
数据分发服务DDS(DataDistributionService)是对象管理组织(OMG)在HLA及CORBA等标准的基础上制定的新一代分布式实时通信中间件技术规范，DDS采用发布/订阅体系架构，强调以数据为中心，提供丰富的QoS服务质量策略，能保障数据进行实时、高效、灵活地分发，可满足各种分布式实时通信应用需求。Data distribution service DDS (DataDistributionService) is a new generation of distributed real-time communication middleware technical specifications formulated by the Object Management Group (OMG) on the basis of HLA and CORBA standards. DDS uses a publish/subscribe system architecture, emphasizing data as the center. Provides rich QoS service quality strategies to ensure that data is distributed in real time, efficiently, and flexibly, and can meet the needs of various distributed real-time communication applications.
现有的DDS网络在节点发现组网阶段采用RTPS(Real-time Publish-Subscribe Protocol实时发布-订阅协议)协议进行规范，该协议将组网发现过程分为两个阶段，分别采用PDP(Participant Discovery Protocol参与者发现协议)协议和EDP(Endpoint Discovery Protocol终端发现协议)协议进行规范，默认采用SPDP(Simple Participant Discovery Protocol简单参与者发现协议)协议和SEDP(Simple Endpoint Discovery Protocol简单端口发现协议)协议，也可配置其他自定义协议。The existing DDS network adopts RTPS (Real-time Publish-Subscribe Protocol real-time publish-subscribe protocol) protocol for specification during the node discovery networking phase. This protocol divides the networking discovery process into two phases, respectively using PDP (Participant Discovery) Protocol Participant Discovery Protocol) and EDP (Endpoint Discovery Protocol) protocol are standardized. By default, SPDP (Simple Participant Discovery Protocol Protocol Simple Participant Discovery Protocol) protocol and SEDP (Simple Endpoint Discovery Discovery Protocol Simple Port Discovery Protocol) protocol are adopted. Other custom protocols can also be configured.
DDS网络节点的DDS模块按照leaseDuration周期通过简单参与者发现协议向其他的DDS网络节点公告自身的参与者信息，由此使得其他的DDS网络节点能够通过该简单参与者发现协议公告找到该DDS网络节点。在无人机组网场景中，网络传输带宽非常有限。这种DDS网络节点的广播式的简单参与者发现协议公告在对于这种网络传输带宽非常有限无人机组网场景来说，属于严重占用网络带宽，对无人机之间的无线网络传输带来了极大的网络负担。另一方面，很多情况下组网的无人机均为提前可知的合法节点，因此没有必要周期性的发布简单参与者发现协议公告。The DDS module of the DDS network node announces its participant information to other DDS network nodes through the simple participant discovery protocol according to the leaseDuration period, thereby enabling other DDS network nodes to find the DDS network node through the simple participant discovery protocol announcement . In the UAV networking scenario, the network transmission bandwidth is very limited. This broadcast-type simple participant of the DDS network node finds that the protocol announcement is a very limited network bandwidth for this type of drone networking scenario, which seriously occupies network bandwidth and brings wireless network transmission between drones. A huge network burden. On the other hand, in many cases, the networked drones are legal nodes that can be known in advance, so there is no need to periodically issue simple participant discovery protocol announcements.

附图说明BRIEF DESCRIPTION
图1是本发明DDS***的结构示意图。FIG. 1 is a schematic structural diagram of the DDS system of the present invention.
具体实施方式detailed description
下面结合附图对本发明做进一步详细说明。The present invention will be further described in detail below with reference to the drawings.
如图1所示，一种带有RTPS协议加速的DDS***，包括由若干DDS节点。图1中节点A、节点B、节点C、节点D均为DDS节点。该DDS***的每个DDS节点包括DDS模块1和加速发现模块2。同一个DDS节点内的DDS模块1和加速发现模块2显而易见的位于同一设备之内。加速发现模块2用于：获取配置文件中的DDS参与者信息清单；然后根据配置文件中的DDS参与者信息清单，按小于leaseDuration的时间间隔，循环向本地的DDS模块按照简单参与者发现协议发送DDS参与者信息清单中的各个DDS参与者信息。其中，leaseDuration为DDS网络简单参与者发现协议中每次公告后节点的有效期。本实施例中DDS模块通过OpenDDS构建。As shown in Figure 1, a DDS system with RTPS protocol acceleration includes several DDS nodes. In Figure 1, node A, node B, node C, and node D are all DDS nodes. Each DDS node of the DDS system includes a DDS module 1 and an accelerated discovery module 2. The DDS module 1 and the accelerated discovery module 2 in the same DDS node are obviously located in the same device. The accelerated discovery module 2 is used to: obtain the DDS participant information list in the configuration file; then, according to the DDS participant information list in the configuration file, at a time interval less than leaseDuration, cycle to the local DDS module according to the simple participant discovery protocol DDS participant information in the DDS participant information list. Among them, leaseDuration is the validity period of the node after each announcement in the DDS network simple participant discovery protocol. In this embodiment, the DDS module is constructed by OpenDDS.
本实施例的工作原理如下：The working principle of this embodiment is as follows:
DDS模块1被配置成不通过简单参与者发现协议向外公告自身的DDS参与者信息。DDS模块1自身设置有用于保存DDS***各个DDS节点的DDS参与者信息的缓冲器。缓冲器中的DDS参与者信息包括leaseDuration参数和存续时间。当DDS模块1按照简单参与者发现协议接收到DDS参与者信息时，DDS模块1遍历缓冲器，倘若缓冲器中没有该DDS参与者信息时，则将该DDS参与者信息存入缓冲器，否则将相应的DDS参与者信息中的存续时间清零。DDS模块1遍历该缓冲器，倘若DDS参与者在缓冲器存续时间超过leaseDuration，则将该DDS参与者从该缓冲器中清除。但由于加速发现模块2按小于leaseDuration的时间间隔循环发送，也意味着，DDS模块1缓冲器中的DDS参与者信息的存续时间永远不会超过leaseDuration，从而使得网络中各个DDS参与者信息持续续存于缓冲器。DDS***中各个DDS节点的DDS模块1之间按照SEDP建立实时发布/订阅业务。SEDP也就是简单端口发现协议。The DDS module 1 is configured not to announce its own DDS participant information through the simple participant discovery protocol. The DDS module 1 itself is provided with a buffer for storing DDS participant information of each DDS node of the DDS system. The DDS participant information in the buffer includes the leaseDuration parameter and duration. When the DDS module 1 receives the DDS participant information according to the simple participant discovery protocol, the DDS module 1 traverses the buffer. If the DDS participant information is not in the buffer, the DDS participant information is stored in the buffer, otherwise Reset the duration of the corresponding DDS participant information to zero. The DDS module 1 traverses the buffer, and if the DDS participant's duration of the buffer exceeds leaseDuration, the DDS participant is cleared from the buffer. However, since the accelerated discovery module 2 is sent cyclically at a time interval less than the leaseDuration, it also means that the duration of the DDS participant information in the buffer of the DDS module 1 will never exceed the leaseDuration, thereby making the information of each DDS participant in the network continue Stored in the buffer. The DDS module 1 of each DDS node in the DDS system establishes a real-time publish/subscribe service according to SEDP. SEDP is also a simple port discovery protocol.
以图1的结构为例，按照正常的RTPS协议规范：节点A入网后，持续公告自己的DDS参与者信息；节点B入网后，收到节点A的公告信息，并向A反馈自己的公告信息，完成节点发现过程，再按照SEDP建立相互订阅与发布业务，而后A和B持续公告自己的DDS参与者信息；节点C入网后，收到节点A、B的公告信息，并向A、B反馈自己的公告信息，完成节点发现过程，再按照SEDP建立相互订阅与发布业务，而后A、B、C持续公告自己的DDS参与者信息；节点D入网后，收到节点A、B、C的公告信息，并向A、B、C反馈自己的公告信息，完成节点发现过程，再按照SEDP协议建立相互订阅与发布业务。至此，如果没有其他的名单机制进行约束，节点A、B、C、D会持续公告自己的DDS参与者信息直至离开网络。而按照本实施例的技术方案：节点A入网后，不公告自己的DDS参与者信息，只会尝试与节点B、节点C、节点D按照SEDP建立实时发布/订阅业务；节点B入网后，节点A和节点B之间没有DDS参与者信息的公告，直接根据缓冲器中的DDS参与者信息和SEDP建立相互之间的实时发布/订阅业务，同样节点C和节点D也是如此，由此节点A、B、C、D无需持续公告自己的DDS参与者信息，从而节约网络传输带宽。Take the structure of Figure 1 as an example, according to the normal RTPS protocol specifications: after node A enters the network, it continues to announce its DDS participant information; after node B enters the network, it receives node A's announcement information and feeds back its announcement information to A , Complete the node discovery process, and then establish mutual subscription and publishing services according to SEDP, and then A and B continue to announce their DDS participant information; after node C enters the network, receive the announcement information of nodes A and B, and feedback to A and B Own announcement information, complete the node discovery process, and then establish mutual subscription and release services according to SEDP, and then A, B, and C continue to announce their DDS participant information; after node D enters the network, receive announcements from nodes A, B, and C Information, and feedback its announcement information to A, B, and C to complete the node discovery process, and then establish mutual subscription and publishing services according to the SEDP protocol. At this point, if there is no other list mechanism to constrain, nodes A, B, C, and D will continue to announce their DDS participant information until they leave the network. According to the technical solution of this embodiment: after node A joins the network, it does not announce its DDS participant information, but only attempts to establish a real-time publish/subscribe service with node B, node C, and node D according to SEDP; after node B joins the network, the node There is no announcement of DDS participant information between A and Node B. The real-time publish/subscribe service is established between DDS participant information and SEDP in the buffer directly. The same is true of Node C and Node D. , B, C, D do not need to continuously announce their DDS participant information, thereby saving network transmission bandwidth.
