they are not proxies.
Basicaly, they received trades and parse them and save them into a dabatase.
Some of them could send a formated message to MQSeries.
The others applications are not currently corrected to the gateways.
They(the clients) feed directly from the database.
If I choose one of the gateways that I want to migrate, it a gateway that
have 2-3 connections to extern providers like (YSX, Nasdaq..) and receive
multiple requests from the clients.
Like a client will connect to the server, ask for a stock's quote and
disconnect when the quote is received. One other client will get a
permanent connection to the gateway and act like a feed. This client will
subscribe to a particuliar stock, and each update done to this stock will be
send back to the client.
that's the kind of application that we have.

It doesn't matter. Server can work with TCP or UDP clients regardless
the way they implemented.

Grizzly works currently in non-blocking mode in other words uses NIO,
which provides better performance for bigger amount of clients and
better scalability.

It means gateway will work as load balancer and redirect requests to
different points depending on there loading? In other words gateway
will work as proxy between client and target market points?
Are you planning to parse incoming messages on server side or you just
need to redirect them?
I just want to understand better how gateway should process requests.
In any case, think, it should be enough easy to build some proxy like
server.
Thanks.
WBR,
Alexey.
