....the router software has been changed so that normal packet routing can be carried out while the routers are dealing with routing update messages. Although it has been speculated that these packet drops were also connected with synchronization, it is unclear, and there is no direct evidence [Sc92, Lo93]. Periodic packet drops have been demonstrated associated with RIP (the Routing Information Protocol [He88] as well as with IGRP. Figure 3 shows audio packet losses during an audiocast 3 of the December 1992 Packet Video workshop [Ja92] The x axis shows the time in seconds; the y axis shows ....

....used, the versions will not pass one. This makes it difficult to recognize invalid entries (which would remain if a deletion failed) This problem could be surmounted by deleting any invalid entries before writing a new entry and raising the version one past the version number of the invalid entry [27]. However, this would mean that the problem could not be handled in the database servers. The name server would need to send to all of the databases to find any invalid entries that might remain in any of the databases. If some were found, the version number of the entry would need to be updated, ....
....The advantage of using UDP is low overhead. Connection oriented protocols require establishment of exclusive connections for each transmission session. To provide the user with reliable byte stream transmission with no record boundaries, the state must be maintained throughout the transmission [27]. This means that this is much slower to implement than simple datagram protocols. Since these connections are exclusive, each remote procedure call to a different host would involve establishing a separate connection. This would either require an inordinate number of connections for any client ....
