Netflix traffic is steered based on your BGP route announcements to your embedded OCAs and at peering sites, as described in detail in the Network Configuration article.
Managing imbalances within an embedded site
When all appliances in a site do not receive identical BGP route advertisements, they cannot stream as much content as would otherwise be possible. As a result, your customers are forced to stream from a backup source for some percentage of their streaming requests.
You can view the current BGP advertisements that you are sending to each embedded OCA on the Route Explorer page in the Partner Portal. You manage BGP route advertisements on your router.
To resolve a BGP imbalance issue, ensure that all of the appliances in each site are receiving identical BGP route advertisements.
In some cases, you may need to ensure that all OCAs in the site have IPv6 addresses and BGP sessions configured for IPv6.
Managing traffic across sites
To discover potential ways to optimize your BGP route announcements across peering and embedded sites, use the Route Optimizer.
To enable efficient nightly fill: If you have OCAs that are located in two different sites, ensure that the appliances within one site can hear the subnets for the appliances in the other site via the BGP connections that are established with your routers. See the Fill patterns article for more details.
If you want to balance traffic equally across two redundant embedded sites, you can open a ticket to request this configuration. See the Network configuration article for more information.
Viewing route performance metrics
To view performance metrics for routes announced across peering and embedded sites, use the Route Performance Report.
This report can help you identify client prefixes in your network that might be experiencing less than optimal Netflix video streaming quality.
