UNCLASSIFIED ESYNC Overview Jason Strom 28 January - 1 February 2019 NIPWG 6 - Rostock, Germany UNCLASSIFIED
UNCLASSIFIED Current Process for Updating Products Most update solutions today rely on building custom patches and levying apply processing on the end user Results in labor-intensive effort by the data provider to produce, quality check, and distribute patch products Results in labor-intensive effort by an end user to retrieve and apply patch products Most update solutions today rely on a baseline where unique patches are only applied to a specific baseline Digital Nautical Charts (DNC) use cumulative Vector Database Updates (VDU) that can only be applied to specific DNC Editions Electronic Navigational Charts (ENC) use sequential patch updates that can only be applied to a Base ENC Cell 2 UNCLASSIFIED
UNCLASSIFIED NGA DNC Updating Today VDU can only be applied to specific DNC Edition VDU can only be applied to specific DNC Edition Requires NGA production of cumulative VDU Requires applying VDU to specific DNC Edition Large file size limits download in low bandwidth Limits updating until new DNC Edition download D N C D N C Labor-intensive production of unique patches Labor-intensive apply processing by end user E D I T I O N E D I T I O N ... ...

UNCLASSIFIED Updating with ESYNC ESYNC incorporates differencing in the infrastructure Eliminates source production of unique patches Eliminates end user need to apply unique patches ESYNC server and client manages patch/apply process Server creates and caches frequently used patches Server dynamically creates any required patch Client manages obfuscated requests for patches Client automatically applies patches for end user ESYNC addresses bandwidth and mission concerns Reduces bandwidth requirement to maintain charts Eliminates limitation of traversing boundaries (i.e. release of new DNC Edition or new Base ENC Cell) 4 UNCLASSIFIED
UNCLASSIFIED NGA DNC Updating with ESYNC Eliminates NGA production of cumulative VDU Limits updating until new DNC Edition download ESYNC patch can be applied to any DNC Edition ESYNC patch can be applied to any DNC Edition Smaller file size (zipped files) for download in low bandwidth About 10x faster applying process by end user D N C D N C E D I T I O N E D I T I O N ... ...

UNCLASSIFIED ESYNC Client 6 UNCLASSIFIED
UNCLASSIFIED Benefits of ESYNC ESYNC is product agnostic Works with any file type Works with compressed or uncompressed files ESYNC Client requires no software installation Executes on secure browser (IE, Edge, Chrome, Firefox) Works on desktop computers and mobile devices ESYNC improves product security Obfuscates update requests to protect user intent Ensures integrity of data throughout update process 7 UNCLASSIFIED
UNCLASSIFIED Future Work with ESYNC Continue development of the service and offer more pilots and use case scenarios Fully implement with customer, it would eliminate the cost and logistics associated with sending out physical disks 8 UNCLASSIFIED
UNCLASSIFIED Summary ESYNC offers a dramatic shift in production and distribution of NGA product updates ESYNC offers a dramatic reduction in labor-intensive chart maintenance by navigation teams Potential to synchronize any data that is periodically updated and distributed to one or more end users ESYNC fulfills a vital need today for intelligent and secure synchronization of information 9 UNCLASSIFIED
