Survey: Fault Tolerance in Distributed File System - Mohammed

  • Abstract
  • Introductions
    • About fault tolerance in any distributed system. Comparison between different file systems.
    • Whats more suitable for Mobile based systems.
    • Why satisfaction high for fault tolerance is one of the main issues for DFS's ?
  • Replication and fault tolerance
    • What is the Replica and Placement policy? What is the synchronization? What is its benefit?
  - Synchronous Method
  - Asynchronous Method
  - Semi-Asynchronous Method
  • Cache consistency and fault tolerance
    • What is the cache? What is its benefit? Cache consistency?
 - Write only Read Many (WORM)
 - Transactional Locking - Read and write locks
 - Leasing
  • Example DFS mentioned in the paper
    • Google File Systems
    • HDFS
    • MOOSEFS
    • iRODS
    • GlusterFS
    • Lustre
    • Ceph
    • PARADISE for mobile
  • Conclusion

Survey on Control Plane Frameworks for Software Defined Networking - Sijo

  • Introduction
    • Traditional Networks - Control Plane and Forwarding Plane
    • Software Defined Networking
- Proposes decoupling of layers into independent layers
- Network entities or nodes are specialized elements which does the forwarding 
- Control applications do not need to worry about installation of the underlying network
  • Theme, Argument Outline
- Look at various control frameworks proposed
  • Controller Platforms
- Centralized and Distributed approaches
- Identify the need to use in controller platforms
- For centralized it started with NOX - Maestro - Beacon - Floodlight - POX - OpenDayLight
- For Distributed : ONIX - Hyperflow - YANC - ONOS
- Leverage parallel processing capabilities
  • In detail about two systems:
    • ONIX
    • ONOS
