End-to-end versus hop-by-hop soft state refresh for multi-hop signaling systems

Jianhua He, Xiaoming Fu, Zuoyin Tang
2009 2009 17th IEEE International Conference on Network Protocols  
The approaches of refreshing state in multi-hop signaling system can be classified as either end-to-end (E2E) or hop-by-hop (HbH).  ...  To ensure state synchronization of signalling operations, many signaling protocol designs choose to establish "soft" state that expires if it is not refreshed.  ...  Acknowledgement The authors would like to thank Hsiao-Hua Chen and anonymous reviewers for their insightful comments.  ...

Modeling Route Change in Soft-State Signaling Protocols Using SDL: A Case of RSVP [chapter]

Constantin Werner, Xiaoming Fu, Dieter Hogrefe
2005 Lecture Notes in Computer Science  
Soft state signaling protocols install and maintain states in network nodes, expiring without receiving refreshes.  ...  As the specifications usually do not describe in detail how to handle these failures, we present insights by developing SDL models for RSVP on this issue.  ...  Soft state protocols developed so far can be categorized into two types: end-to-end protocols and hop-by-hop protocols.  ...

Shinya Ishida, Shin'ichi Arakawa, Masayuki Murata
2006 2006 3rd International Conference on Broadband Communications, Networks and Systems  
In the soft-state control mechanism, each node sets a timer for each control state and resets the timer with refresh messages to maintain the state.  ...  RSVP-TE is a signaling protocol to setup and teardown lightpaths in wavelength-routed GPMLS networks. RSVP-TE uses the soft-state control mechanism to manage lightpaths.  ...  Acknowledgments This work was supported in part by a Grant-in-Aid for Young Scientists (A) 17680004 from the Ministry of Education, Culture, Sports, Science and Technology of Japan.  ...

LiT is multi-channel capable and is centrally controlled. It achieves robustness in the face of wireless packet errors by making extensive use of soft-state mechanisms.  ...  While there is plentiful literature on the use of TDMA for wireless mesh networks, a practical multi-hop TDMA system remains elusive. In this regard, LiT addresses several practical concerns.  ...  Thanks to Swanand and Victor for their help during outdoor experiments.  ...
