## Node Discovery Protocol v5
|
||||
##
|
||||
## Node discovery protocol implementation as per specification:
|
||||
## https://github.com/ethereum/devp2p/blob/master/discv5/discv5.md
|
||||
##
|
||||
## This node discovery protocol implementation uses the same underlying
|
||||
## implementation of routing table as is also used for the discovery v4
|
||||
## implementation, which is the same or similar as the one described in the
|
||||
## original Kademlia paper:
|
||||
## https://pdos.csail.mit.edu/~petar/papers/maymounkov-kademlia-lncs.pdf
|
||||
##
|
||||
## This might not be the most optimal implementation for the node discovery
|
||||
## protocol v5. Why?
|
||||
##
|
||||
## The Kademlia paper describes an implementation that starts off from one
|
||||
## k-bucket, and keeps splitting the bucket as more nodes are discovered and
|
||||
## added. The bucket splits only on the part of the binary tree where our own
|
||||
## node its id belongs too (same prefix). Resulting eventually in a k-bucket per
|
||||
## logarithmic distance (log base2 distance). Well, not really, as nodes with
|
||||
## ids in the closer distance ranges will never be found. And because of this an
|
||||
## optimisation is done where buckets will also split sometimes even if the
|
||||
## nodes own id does not have the same prefix (this is to avoid creating highly
|
||||
## unbalanced branches which would require longer lookups).
|
||||
##
|
||||
## Now, some implementations take a more simplified approach. They just create
|
||||
## directly a bucket for each possible logarithmic distance (e.g. here 1->256).
|
||||
## Some implementations also don't create buckets with logarithmic distance
|
||||
## lower than a certain value (e.g. only 1/15th of the highest buckets),
|
||||
## because the closer to the node (the lower the distance), the less chance
|
||||
## there is to still find nodes.
|
||||
##
|
||||
## The discovery protocol v4 its `FindNode` call will request the k closest
|
||||
## nodes. As does original Kademlia. This effectively puts the work at the node
|
||||
## that gets the request. This node will have to check its buckets and gather
|
||||
## the closest. Some implementations go over all the nodes in all the buckets
|
||||
## for this (e.g. go-ethereum discovery v4). However, in our bucket splitting
|
||||
## approach, this search is improved.
|
||||
##
|
||||
## In the discovery protocol v5 the `FindNode` call is changed and now the
|
||||
## logarithmic distance is passed as parameter instead of the NodeId. And only
|
||||
## nodes that match that logarithmic distance are allowed to be returned.
|
||||
## This change was made to not put the trust at the requested node for selecting
|
||||
## the closest nodes. To counter a possible (mistaken) difference in
|
||||
## implementation, but more importantly for security reasons. See also:
|
||||
## https://github.com/ethereum/devp2p/blob/master/discv5/discv5-rationale.md#115-guard-against-kademlia-implementation-flaws
|
||||
##
|
||||
## The result is that in an implementation which just stores buckets per
|
||||
## logarithmic distance, it simply needs to return the right bucket. In our
|
||||
## split-bucket implementation, this cannot be done as such and thus the closest
|
||||
## neighbours search is still done. And to do this, a reverse calculation of an
|
||||
## id at given logarithmic distance is needed (which is why there is the
|
||||
## `idAtDistance` proc). Next, nodes with invalid distances need to be filtered
|
||||
## out to be compliant to the specification. This can most likely get further
|
||||
## optimised, but it sounds likely better to switch away from the split-bucket
|
||||
## approach. I believe that the main benefit it has is improved lookups
|
||||
## (due to no unbalanced branches), and it looks like this will be negated by
|
||||
## limiting the returned nodes to only the ones of the requested logarithmic
|
||||
## distance for the `FindNode` call.
|
||||
|
||||
## This `FindNode` change in discovery v5 will also have an effect on the
|
||||
## efficiency of the network. Work will be moved from the receiver of
|
||||
## `FindNodes` to the requester. But this also means more network traffic,
|
||||
## as less nodes will potentially be passed around per `FindNode` call, and thus
|
||||
## more requests will be needed for a lookup (adding bandwidth and latency).
|
||||
## This might be a concern for mobile devices.
