Felföldi Zsolt	0851646e48	les, les/lespay/client: add service value statistics and API (#20837) ... This PR adds service value measurement statistics to the light client. It also adds a private API that makes these statistics accessible. A follow-up PR will add the new server pool which uses these statistics to select servers with good performance. This document describes the function of the new components: https://gist.github.com/zsfelfoldi/3c7ace895234b7b345ab4f71dab102d4 Co-authored-by: rjl493456442 <garyrong0905@gmail.com> Co-authored-by: rjl493456442 <garyrong0905@gmail.com>	5 years ago

Felföldi Zsolt	c2003ed63b	les, les/flowcontrol: improved request serving and flow control (#18230) ... This change - implements concurrent LES request serving even for a single peer. - replaces the request cost estimation method with a cost table based on benchmarks which gives much more consistent results. Until now the allowed number of light peers was just a guess which probably contributed a lot to the fluctuating quality of available service. Everything related to request cost is implemented in a single object, the 'cost tracker'. It uses a fixed cost table with a global 'correction factor'. Benchmark code is included and can be run at any time to adapt costs to low-level implementation changes. - reimplements flowcontrol.ClientManager in a cleaner and more efficient way, with added capabilities: There is now control over bandwidth, which allows using the flow control parameters for client prioritization. Target utilization over 100 percent is now supported to model concurrent request processing. Total serving bandwidth is reduced during block processing to prevent database contention. - implements an RPC API for the LES servers allowing server operators to assign priority bandwidth to certain clients and change prioritized status even while the client is connected. The new API is meant for cases where server operators charge for LES using an off-protocol mechanism. - adds a unit test for the new client manager. - adds an end-to-end test using the network simulator that tests bandwidth control functions through the new API.	6 years ago

Felföldi Zsolt	a5d08c893d	les: code refactoring (#14416) ... This commit does various code refactorings: - generalizes and moves the request retrieval/timeout/resend logic out of LesOdr (will be used by a subsequent PR) - reworks the peer management logic so that all services can register with peerSet to get notified about added/dropped peers (also gets rid of the ugly getAllPeers callback in requestDistributor) - moves peerSet, LesOdr, requestDistributor and retrieveManager initialization out of ProtocolManager because I believe they do not really belong there and the whole init process was ugly and ad-hoc	8 years ago
