Fast network restoration with equivalent cooperative routing

Fang Dong, Jianyang Huang, Penghao Sun, Yuxiang Hu
2017 Journal of Communications and Information Networks  
Aiming at the problem of failure recovery in current networks, a fast failure recovery method based on equivalent cooperative routing is proposed.  ...  The experimental results show that the proposed method has a low failure recovery delay under a relatively small flow table cost.  ...  A proactive failure recovery scheme calculates the backup path for the link before a failure occurs.  ...

Real time cooperative editing on the Internet

Yun Yang, Chengzheng Sun, Yanchun Zhang, Xiaohua Jia
2000 IEEE Internet Computing  
New research and a prototype implementation solve some fundamental problems in distributed, real-time, cooperative editing in the Internet environment.  ...  The REDUCE system's strategies include a novel consistency model and responsiveness techniques that permit arbitrary order in executing independent operations.  ...  To increase REDUCE reliability in the Internet environment, we have used a variation of the primary-backup model (see Budhiraja et al. 8 ) to tolerate the single server failure as depicted by the backup  ...
