Enterprise Environment - Blue Leader
The Blue Leader is a feature of StifleR Enterprise. On each Subnet the Red Leader is responsible for downloading the content across the WAN. On that and all the other subnets at the Location, Blue Leaders are automatically assigned. These Blue leaders are able to communicate with the other Leaders at the Location to facilitate the sharing of cached content between Peers across subnet boundaries at the local level.
A Blue Leader is basically a Red Leader (Assigned using the same selection process) but stripped of allowed WAN bandwidth consumption.
This feature requires Port 3703 (UDP) to be open for Multicast communication from Blue Leaders to
Clients on the local network segment. All leaders communicate with other leaders on ports 3704 and 3705 (UDP). Also check that the Microsoft BranchCache port is reachable and also the Blue Leader BranchCache port, which is typically assigned to the port one above the Microsoft BranchCache port number.
Note: At the time of writing the Leader communication Ports mentioned above are hard coded into the current version.
Note: BranchCache operates on port 80 by default, so the InterVLAN transfer will be handled on port 80 + 1 = 81. Both of these ports can be used by other applications so please ensure that this is configured properly. To avoid such issues our best practice recommendation is to use a custom port for BranchCache e.g. 1337 which would mean that you would then configure the InterVLAN port to be 1338 (default).
Blue Leaders do not generate V1 Content, only the Red Leaders make these hash calculations.
