network layer and network management entity

the network layer routes the data grams to the appropriate functional unit or program addressed; it also isolates the upper layers from the different technologies that are making the connections
NOTE: Network Protocols such as PPP (Point to Point Protocol), IPv6, IPX, ROHC (Robust Header Compression), and others that may be needed operate in this layer. The Network Layer implements the…

the network layer routes the data grams to the appropriate functional unit or program addressed; it also isolates the upper layers from the different technologies that are making the connections
NOTE: Network Protocols such as PPP (Point to Point Protocol), IPv6, IPX, ROHC (Robust Header Compression), and others that may be needed operate in this layer. The Network Layer implements the functionality of Global multicast, RSVP (Resource Reservation Protocol), diffserv (differentiated service), NEMO (Network Mobility), IPsec (IP Security), IP Firewall, Static Routing, Dynamic Routing Protocol NDP (Network Discovery Protocol), DHCP (Dynamic Host Configuration Protocol), and SLAAC (Stateless Address Auto-Configuration). The network Management Entity responds to commands from the CALM Management Entity to modify the routing table of the resident device so that data grams from the managed application will flow to the desired destination.

packet-centric dissemination

a source node defines a geographical destination area and distributes information to appropriate neighbors; receiving nodes being outside the destination area re-distribute the information to appropriate neighbors; receiving nodes being inside the destination area broadcast the information.
