I. INTRODUCTION DTN is fundamentally an intermittent network, where the communication links only exist temporarily, rendering it impossible to establish end-to-end connections for data delivery. Delay Tolerant Networking (DTN) is a new area of research in the field of networking that deals with extending existing protocols or inventing new ones in a coordinated, architecturally clean fashion, to improve network communication when connectivity is periodic, intermittent and/or prone to disruptions
Disruption-Tolerant Networking (DTN) is a new communication paradigm that can span across multiple networks and cope with harsh conditions not envisioned in the Internet model. Delay-tolerant networks (DTNs) are partitioned wireless ad hoc networks with intermittent connectivity. Additional terminology in this family of dynamic networks includes disruption-tolerant networks, intermittently connected networks, and opportunistic networks. Routing of the packets in DTN is based on store-carry-and forward
high data loss rates. This led to the designation of a more effective protocol architectures represented by Delay Tolerant Networking (DTN) which makes communication in such environment easier and more applicable. Delay Tolerant Networking is an end-to-end architecture for data transfer in challenged networks. To solve the problem of intermittent connectivity, DTN represented the Bundle protocol which resides between the transport and the application layers and forms a store-and-forward network.
when the transmitters queue occupancy becomes low building up gradientstowards the destinations faster reducing packetlooping. Using redundancy this algorithm works well both in high and low traffic conditions giving maximum network throughput in DTNs. Works Cited http://en.wikipedia.org/wiki/Backpressure_routing

INPUT/OUTPUT CRASH COURSE Meridian crash course faq798-5880 Posted: 20 May 05 (Edited 3 Jun 05) Programming Meridian SL1 PBX This is a short introduction into programming a Meridian PBX. The Meridian PBX's software divides information into LOADS. Each Load has a specific function for example. LD 20 is where you can print information about phones. The loads range from LD 01 - LD 143 How to HyperTerminal in to the PBX and VOICEMAIL Systems. 1. Launch HyperTerminal 2. Set phone number to your modem
