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    • Assists in reassignment of clients when a registered server is no longer active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