But the bits to bits arbitration of the CAN protocol defines a static priority to messages exchanged. Due to the fact of the lack of timing information for non periodic data transmission, it is impossible to find a static manner to attribute CAN identifiers to exchanged objects so that applications periods limit can be always be satisfied. When one or many network stations send data using the same identifier, at some point, data will differ and generate error. All stations will then back off and retransmit restarting the whole process. In this case, retransmission can lockup the network.

然而， CAN总线采用位仲裁技术，利用信息的标识符域定义了一种静态的优先权，由于非周期数据传输时缺乏时间信息，不可能找到一个静态标识符分配方案永远满足应用程序对时间的要求；当一个或多个网络节点同时发送标识符相同的数据时，如果数据不同，所有节点都要重新发送数据，在这种情况下，网络将阻塞。

Simulations show that,using this algorithm , the size of the resultant dominating set is smaller, so the algorithm can reduce the retransmission nodes and save network resources efficiently in broadcasting.

The method for requesting data retransmission retransmits a plurality of data through the information state PDU with a plurality of data, saves the consumption of the state PDU and improves the system retransmission efficiency.

本发明通过一个携带多个数据的信息状态PDU，重传多个数据，节省了状态PDU的开销，提高了系统的重传效率。

A method for retransmitting data in overlay route network include forming overlay route network by laying overlay network node in existing bottom layer network for providing totally transparent overlay route and data retransmission service between user hosts being switched in, packaging and retransmitting as well as unpackaging user IP packet in data retransmission course then sending it to destination host for raising end to end transmission performance.

覆盖路由网络中数据转发的方法属于覆盖网络中的路由和转发技术领域，其特征在于：通过在现有底层网络中部署覆盖网络路由节点形成覆盖路由网络，为接入的用户主机之间提供完全透明的覆盖路由和数据转发服务，在数据转发过程中，用户的IP分组被封装、转发、解封装，最终发送到目的主机，实验表明在较小规模的覆盖路由网络的全连接拓扑里，同时使用跳数受限机制寻找到的路由路径会比Internet路由性能更高，而且底层网络出现故障时，覆盖路由网络能迅速绕过故障区域，从而提高了端到端的传输性能。
