There are front end services and back end +services. +Client are connected with on front end service and front end services are +connected with back end services. +There's only one login service for all shards. The client first connects to +the login service that checks the validity of the account, after the client +choose the shard. The login service warn the shard (via welcome service (one +per shard)) that a new client will come. The welcome service chooses the +best front end for the client and sends the choosen front end to the login +service and the login service sends this info to the client. after, the +client connects to the selected front end and authenticates. + +><i> But how clients are balanced between the N front ends of a shard ? +</I> +For now, the welcome service does a dumb balancement (try to have the same +player number on each front end). + +><i> It will be done by a generic load balancer (hardware) +</I>><i> or a specific service from NEL ? +</I> +It s the welcome service that do that. + +><i> The source code of the load balancer and the front end are delivered with +</I>><i> NEL ? +</I> +Look the welcome service :-) + +><i> If there a description of all NEL services ? +</I> +Look the net part of <A HREF="http://www.nevrax.org/docs/">http://www.nevrax.org/docs/</A> +And also try here <A HREF="http://www.nevrax.org/docs/doxygen/nel/pages.html">http://www.nevrax.org/docs/doxygen/nel/pages.html</A> + +Vianney Lecroart +--- +lead network programmer / nevrax.com +icq#: 6870415 +homepage: <A HREF="http://ace.planet-d.net">http://ace.planet-d.net</A> +www.geekcode.com: GCS/E d- s+++: a-- C+++$ UL++ P- L+++>+$ E+>- W++ N+ o?
