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).

1. Single client on single network – Template/Location settings apply.

2. Three clients on single network – MC disabled – Hosted cache mode.

3. Multiple networks – few clients on each. Hosted Cache mode.

4. Multiple networks

5. Multiple clients in distributed mode. BL & GL on one machine.

6. Few clients on other networks – used single BL & GL

7. Multiple networks

8. Multiple clients in distributed mode. BL & GL on one machine.

9. A bit more than few clients on other networks – used BL on same subnet

10. Multiple networks

11. Multiple clients in distributed mode. BL & GL on one machine.

12. Multiple clients in distributed mode. BL & GL on one machine.

Ideas:

1. 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
