DVMRP is cheaper and cost effective
when compared to other alternatives for increasing LAN and WAN capacities.
Reduces the load on the sending
server, which no longer supports sequential or concurrent unicast sessions
due to the scalability factor.
Gets rid of network congestion
that is caused by existing applications, which are inefficiently
transmitting to other groups.
Saves cost in utilization of
network and server resources.
As more users are added over
the network, there is no change in the amount of bandwidth over the users.
Can add new types of applications
due to the multicasting mode of transmission.
DISADVANTAGES...
DVMRP can build a lot
of traffic if the routers are sending datagrams to sparsely connected nodes
or if
routers are spread apart. For this reason, DVMRP is only efficient when
it is on dense transmissions on high bandwidth connections.
If a shortest path tree is created
for every group ID sent, this information is overwhelming. This shows that
DVMRP is limited for scalability.
