Examples of Leader Selection
Example scenario #1 - Campus style location
No local servers
500 clients
Several ethernet as well as a single WiFi network
BL on each physical network
GL’s on physical network serving WiFi clients
As GL are also distributed clients, they will serve BL’s
Example scenario #2 - Small location with few clients
One physical subnet and one WiFi subnet - so Location has two Network Groups
WiFi is routed separately to ethernet – multi location
50 clients
No BL’s
No Green Leader
Two separate Red Leaders downloading seperate
Scenarios
Two subnets in distributed mode with just bridged distributed mode
Two networks, four clients. Two Blue Leaders two client participating.
In this case, we have several machines in each subnet. We bridge the probe messages and the probe matches, and also cache some key data. We bridge the Red Leader info first.
Two subnets in distributed mode with just bridged distributed mode
Two networks, three clients. Two Blue Leaders. One client requesting.
In this case, we have several machines in each subnet. We bridge the probe messages and the probe matches, and also cache some key data. We bridge the Red Leader info first.
One client in each network (Green Leader)
In this scenario we have two (or more) clients in each network. One of them will get the Green Leader role, and the other connects using Hosted Cache mode. In this case one machine will be Hosted Cache server (Green leader) and the other client gets it from the GL. The GL machine itself will be in any mode (distributed, local, hosted cache).
Single client on single network – Template/Location settings apply.
Three clients on single network – MC disabled – Hosted cache mode.
Multiple networks – few clients on each. Hosted Cache mode.
Multiple networks
Multiple clients in distributed mode. BL & GL on one machine.
Few clients on other networks – used single BL & GL
Multiple networks
Multiple clients in distributed mode. BL & GL on one machine.
A bit more than few clients on other networks – used BL on same subnet
Multiple networks
Multiple clients in distributed mode. BL & GL on one machine.
Multiple clients in distributed mode. BL & GL on one machine.
Ideas:
If over x clients we add more GLs?
Blue Leader requesting content logi flow
Allow selection of Green Leaders
Selected Green Leaders becomes Blue Leaders on distributed networks
If we have 2 wifi networks with small number of clients and one distributed in same network group, the Green Leader is on distributed network only
Multiple Green Leaders from Subnet
One BL per subnet
Should we plan for multiple?
BL stops forwarding requests after 50 clients on subnet
