 # Proposed Architecture
 
-The gRPC load balancing approach follows the third approach, by having an
-external load balancer which provides simple clients with a list of servers.
+The gRPC load balancing implements the external load balancing server approach:
+an external load balancer provides simple clients with an up-to-date list of
+servers.

+
+1. On startup, the gRPC client issues a name resolution request for the service.
+   The name will resolve to one or more IP addresses to gRPC servers, a hint on
+   whether the IP address(es) point to a load balancer or not, and also return a
+   client config.
+2. The gRPC client connects to a gRPC Server.
+   1. If the name resolution has hinted that the endpoint is a load balancer,
+      the client's gRPC LB policy will attempt to open a stream to the load
+      balancer service. The server may respond in only one of the following
+      ways.
+      1. `status::UNIMPLEMENTED`. There is no loadbalancing in use. The client
+         call will fail.
+      2. "I am a Load Balancer and here is the server list." (Goto Step 4.)
+      3. "Please contact Load Balancer X" (See Step 3.) The client will close
+         this connection and cancel the stream.
+      4. If the server fails to respond, the client will wait for some timeout
+         and then re-resolve the name (process to Step 1 above).
+   2. If the name resolution has not hinted that the endpoint is a load
+      balancer, the client connects directly to the service it wants to talk to.
+3. The gRPC client's gRPC LB policy opens a separate connection to the Load
+   Balancer. If this fails, it will go back to step 1 and try another address.
+   1. During channel initialization to the Load Balancer, the client will
+      attempt to open a stream to the Load Balancer service.
+   2. The Load Balancer will return a server list to the gRPC client. If the
+      server list is empty, the call will wait until a non-empty one is
+      received. Optional: The Load Balancer will also open channels to the gRPC
+      servers if load reporting is needed.
+4. The gRPC client will send RPCs to the gRPC servers contained in the server
+   list from the Load Balancer.
+5. Optional: The gRPC servers may periodically report load to the Load Balancer.
