Flow integrity errors refer to missing block of data, may be lost in the network due to its have been delivered to a wrong destination.

Data is sent as data packets across a data network. it is not neccessary that data packets sent by a source to the destination take the same path. packet i goes through nodes A, B and D. packet 2 goes directly from node A to D. Packet 3 goes from A to D through nodes B and C. Flow of these data packets from the source to the destination may be affected in several ways.

A Multipoint (also called multidrop) connection is one in which more than two specific devices share a single link as in a multipoint environment, the capacity of the channel is shared, either spatially or temporarily. If several devices can use the link simultaneously, it is a spatially shared connection. If users must take turns, it is a timeshared connection. in a multipoint connection, the same link is used by many systems where as a dedicated link is requried between any two systems in a point to point connection. Hence multipoint connection requirs less cabling and thereby reduces the cost. Multipoint connection has ease of installation and low cost. These connections are used over fail over and reliable.
