Single Request Architecture

Description

Is there any plan for implementing SRA (Single Request Architecture)? At the moment, if a page contains 6 slots and we want to auction them between 4 bidders, we need to make 24 concurrent requests. With SRA, only 4 calls will be needed.

This has two main advantatges:

• Optimization. Not only header bidding should be faster, but the rest of elements in the page could be downloaded faster, as more download threads would be free.
• Tandem ads. So, a provider could bid for a slot group in order to show related ads

And some complications:

• Obviously, bidders must agree accepting SRA. But it's not mandatory. prebid.js could use SRA when available and multi request when not. Publishers may decide to work only with ones implementing SRA.
• Algorithm for maximizing profit must be more complicated, taking into account slot group bids.

I always thought that SRA should be the default option, and I supposed that there were some important reasons why it isn't. But it seems that other wrappers are already doing this, so I'm wondering if it will be available on prebid.js in the future.

@sinuhepop Yes ideally everyone would support this, but some do not. I don't have the data readily available but I would guess more than 50% of demand partners do not support SRA.

We have plans on building an optimized version of prebid (prebid 1.0.0) that will have a requirement to be SRA. We should have an intent to implement before the end of the year. Thanks

Sounds good. Thanks.

Thx
