How Push Technology overcomes these challenges…
• Publish / Subscribe integration pattern:
– Realtime – data updates are pushed to clients without polling
• Congested networks need data saving techniques:
– Delta streaming – only transmit what you need
• Robustness during adverse conditions:
– Reliable Reconnect – to overcome unreliable network conditions without data loss
