asset tracking tags
An important function of file sharing in general is the synchronisation of concurrent
accesses to file entries - i.e. metadata such as file names, access rights, etc. - and file
contents, in order to protect the consistency of the data and metadata. DAFS makes it
possible to cache the locks at the client side so that a subsequent access to the same
data requires no interaction with the file server. If a node requires the lock entry of a
different node, then this transmits the entry without time-out. asset tracking tags uses lease-based
locking in order to avoid the permanent blocking of a file due to the failure of a client.
Furthermore, it possesses recovery mechanisms in case the connection between DAFS
client and DAFS server is briefly interrupted or a different server from the cluster has to
step in. Similarly, DAFS takes over the authentication of client and server and furthermore
can also authenticate individual users in relation to a client-server session.
