WAN File Services Artifact

Interpret and conduct research to improve the body of knowledge relating to ICT.

This artifact investigates a network file service problem.   End users complained of slow file browsing, slow file enumeration, and a random inability to save Microsoft Word files from a branch office.  ICT methodology determined that the problem resulted from server message block (SMB) network protocol limitations.   Recommendations were made to resolve the issues.

This artifact explores advanced SMB protocols and ICT methodology.  Additionally, it explores numerous WAN technologies: wide area file systems (WAFS); distributed file services (DFS); DFS replication (DFSR); and Microsoft BranchCache.

Legacy SMB protocol was singled out from a series of network tests.  Data statistics were gathered with network latency, bandwidth, and performance tests.

SMB2 was considered the enhanced protocol at the time the research was conducted.  SMB2 was followed by SMB 2.1 and SMB 3.0.  Microsoft released SMB 3.1, along with Windows 8.1 on October 17th, 2013.

SMB 3.1 provides file service innovations to any organization.  SMB advancements help organizations as follows: reduceds CPU workloads; reduces disruptions to shared resources; protocol encryption prevents eavesdropping; improved response times to branch offices, etc... (Microsoft, 2013).

SMB protocol is only one of the many innovations introduced by Windows 8.1 and Windows 2012R2.  ICT methodology ensures systems are ready for upgrades through careful analysis of the adoption, implementation, development and use phases.
