EMWIN ByteBlaster

Internet File Push


• Byte Blaster:


     – Client/Server Internet Based Service (NWS is one of many participants)

          • Client software is used to receive products from other servers

          • Local server may have many clients - when a file is received it is immediately re-distributed      

          • A server may collect products from different sources (e.g., satellite broadcast, local LAN, or as a client to another ByteBlaster server)

          • Multiple daisy chains are possible: Server -> Client/Server -> Client/Server ->…    

       – LoadMaster (NWS )

          • Agent for load balancing clients on registered servers

          • Assists in reassignment of clients when a registered server is no longer active

• Future Service Outlook:


     – IDP Environment does not currently support the Windows environment.

     – Existing operational IDP file-push protocol (e.g., XMPP) does not adequately support binary file transfer today.

     – Alternative 1: Switch to NWWS End User Client software to receive a portion of the EMWIN distribution

          • Provides an Internet push of all EMWIN US-National text products, and then some

          • Does not include EMWIN International or Image Products

     – Alternative 2: Continue to operate client/server networks in absence of the NWS ByteBlaster Servers and LoadMaster.
