PubSubHubbub

Publisher SubscriberHub


PubSubHubbub

1.Subscriber gets Publisher’s feed. The feed contains a link to the Hub.

Publisher Subscriber

Give me your latest

content for feed X, please.


PubSubHubbub

1.Subscriber gets Publisher’s feed. The feed contains a link to the Hub.

Publisher Subscriber

I've delegated distribution of that content to this Hub.


PubSubHubbub

2.Subscriber POSTs subscription request to the Hub. The request contains the URL where the Hub should POST new updates to the Subscriber.


I want to subscribe to feed

X. Send updates to this URL


PubSubHubbub

3.Hub hits the URL to verify the request was authentic; Subscriber responds with confirmation to the Hub.


Hey there! Did you really send this

request?


PubSubHubbub

3.Hub hits the URL to verify the request was authentic; Subscriber responds with confirmation to the Hub.


Yup, that was really me, not a DoS attacker.


PubSubHubbub

4.a) Publisher notifies Hub about updates by POSTing feed URLs to the Hub; Hub pulls the feed again to find new entries.

I have new content for feed

X for you!



PubSubHubbub

Give me your latest





PubSubHubbub

Here you go.




PubSubHubbub

4.b) If the Publisher does not inform the Hub, the Hub will periodically poll the Publisher’s feed for new updates.

Give me your latest




PubSubHubbub

Here you go.


4.b) If the Publisher does not inform the Hub, the Hub will periodically poll the Publisher’s feed for new updates.


PubSubHubbub

New update to feed X! Here

you go.


5.When Hub receives new update to feed X, it POSTs the update to the Subscriber’s endpoint URL.


PubSubHubbub

New update to feed X! Here

you go.


6. If feed X has multiple subscribers, the Hub sends updates to all of them. This reduces load on the Publisher.
