PUSH e-mail

Main features:
• INTEROPERABILITY - Interfacing at UDP/ip level to any DVB/ip GW
• Downloading e-mails from any end-user's POP3 server to broadcast center
• Reliable transmission over one-way link (satellite, terrestrial, cable) without availability of acknowledgment mechanism of TCP/ip protocol
• FEC + rebroadcast implemented
• Automatic Synchronization checking of received e-mails with PUSH e-mail Server
• RSA/DES ENCRYPTION for e-mails on the fly implemented

PUSH e-mail System serves for downloading e-mails from remote POP3 servers and their instant automatic transmission via a one-way link using UDP/ip interface through any DVB/ip GW (IP encapsulator).

PUSH e-mail System brings to end-users significant increase in comfort as incoming e-mails are received automatically without any intervention from an user side at significantly higher speeds of DVB link comparing to ordinary dial-up (up to 20 Mbit/s to end-user).

From economic point of view it eliminates PTT dial-up fees for connections required just for sending acknowledgment for received e-mails and checking inbox for incoming e-mails.

This for example eliminates worries of end-users to have e-mail box frozen due to some huge email being received (for example 8 Mbyte of data with 2-3 failures during download can cause unpleasant delay in receiving the rest of e-mails).

It is an attractive add-on mainly to Asymmetric Broadband Internet Systems (satellite, terrestrial or cable). PUSH e-mail System enables Users to fully benefit from broadband one-way link he made investment into. PUSH e-mail System can be used in conjunction with any third party DVB/ip GW (IP encapsulator) with MPE encapsulation.
