... The key to understanding the constraints of MBone is thinking about bandwidth. The reason a
multicast stream is bandwidth-efficient is that one packet can touch all workstations on a network.
Thus, a 128-kilobit per second video stream (typically 1-4 frames per second) uses the same
bandwidth whethe ...
... IP flow refers to a sequence of datagrams
– from one source to one destination, identified by the ordered pair
– can also refer to a flow at finer granularity, e.g., different applications
between same pair of machines, identified by < source address, source p ...

where traffic on the network and the number of user increase continuously.
The Switch with its small, compact size was specifically designed for small to middle
workgroups. This Switch can be installed where space i ...
... B is the first DTN node in the path from O to T. It
maintains a timer that kicks off after getting the RREQ
and listens for an RREP from T. If node T fails and does not
send an RREP before B’s timer expires, B sends a special
“DTN-Only” RREP to allow nodes to still learn the DTN

• In SSM, an IP datagram is transmitted by a
source S to an SSM destination address G, and
receivers can receive this datagram by

... gossiping with a distant node is extremely important because sometimes message loss could affect an entire locality. Hence we need a scheme that would gossip locally with
a very high probability and with distant nodes occasionally. Our AG protocol is augmented to achieve this optimization. Here, we ...

snoop on all transmissions and store the overheard packets for

The learning algorithm is purely local, opportunistic

algorithm is that a path is “valid” or forwarding along a path exists if the path suffix is valid. In the first phase a router

A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other along network links (data connections). The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other.Computer networks differ in the transmission media used to carry their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent. In most cases, communications protocols are layered on (i.e. work using) other more specific or more general communications protocols, except for the physical layer that directly deals with the transmission media.Computer networks support applications such as access to the World Wide Web, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications.
