That's correct but note that xDS spec already exists as linked above and it 
is not something new that gRPC team is proposing.

Re: [grpc-io] Re: Evolution of gRPCLB

[Rama Rao]

Srini,

Does it mean that if control plane implements the new xDS api that gRPC
team is going propose - gRPC services can make use of it for load balancing
(optionally control planes can also implement and configure
LoadReportService, which would be used for more intelligent load
balancing?) Is that right?
Thanks,
Rama

gRPC team does not work on the LB server side of xDS. The goal here is to 
be able to use existing and future xDS compatible LB servers as mentioned 
above.

We are actively working on a project using a LookAside loadbalancer.
It would be great if XDS existed before deprecating grpclb,

[grpc-io] Re: Evolution of gRPCLB

[blazej . mroz24]

As I mentioned here 
, we have 
been working on server-side gRPCLB implementation for some time and we'll 
start using it any day now. We chose gRPCLB because we needed high 
performance. It would be great to have some time for migrating to xDS, 
before gRPCLB gets removed. 

Do you work on both sides of xDS protocol, or only on the client-side 
implementation?

Re: [grpc-io] Re: Evolution of gRPCLB

['Mark D. Roth' via grpc.io]

We don't currently support a way to plug in third-party resolvers and LB
policies in C-core without rebuilding it, but that's a feature we are
working on.  On the resolver side, there's a user-contributed PR that's
been in review for a while (https://github.com/grpc/grpc/pull/16617), which
you can ping if you're interested.

[grpc-io] Re: Evolution of gRPCLB

[Benjamin Krämer]

We are currently using GRPCLB to workaround the missing name resolver 
support in C# (https://github.com/grpc/grpc/issues/11879). We will switch 
to xDS once it's implemented, but would still appreciate to get a 
possibility to use external name resolvers in c-core (doesn't have to be 
C#). grpc-java offers an experimental API for this: 
https://github.com/grpc/grpc-java/issues/1770

AFAIK, c-core only supports adding custom name resolvers by compiling the 
c-core yourself, which would then allow to also use it with C#. Is this 
still the case, or is there a standard way by now?
