Datagram, Virtual circuit, Source routing approach
|
|
|
Datagram/Connectionless approach empezar lección
|
|
include in very packet just enough information to enable any switch to decide how to get it to its destination
|
|
|
Virtual Circuit/Connection-oriented approach empezar lección
|
|
setting up a virtual connection from the source host to the destination host before any data is sent
|
|
|
|
empezar lección
|
|
all the information about network topology that is required to switch a packet across the network is provided by the source host
|
|
|
|
empezar lección
|
|
switch consults with such table to decide how to forward a packet (what path should it choose)
|
|
|
|
empezar lección
|
|
does not forward all frames it receives. It builds a MAC address table to intelligently forward data only to the destination port by learning which device is connected to which port
|
|
|
|
empezar lección
|
|
subset of the actual network topology that has no loops and that reaches all the devices in the network, solves problem with loops
|
|
|
|
empezar lección
|
|
switch forwards a frame with a destination broadcast address out on each active port (except the one on which the frame was received)
|
|
|
|
empezar lección
|
|
each host decide for itself whether or not to accept the incoming message
|

|
|
Virtual LANs, allow a single extended LAN to be partitioned into several seemingly separate LANs
|
|
|
|
empezar lección
|
|
Network was understanded as either a directly connected or a switched network. Internetwork is interconnected collection of such networks
|
|
|
|
empezar lección
|
|
defines the framework for how network layers or providers offer functions to users
|
|
|
|
empezar lección
|
|
receiving a packet, looking up its destination address in a table and sending the packet in a direction determined by that table
|
|
|
|
empezar lección
|
|
process by which forwarding tables are built
|
|
|
|
empezar lección
|
|
node automatically sends an update message to its neighbour nodes so that the other nodes know that this node is still running
|
|
|
|
empezar lección
|
|
whenever a node notices a link failure or receives an update from one of its neighbors that causes it to change one of the routes in its routing table, it forward this update to its neighbours
|
|
|
|
empezar lección
|
|
node constructs a one-dimensional array containing the ‘distances’ to all other nodes in the network and share that vector with its neighbors
|
|
|
Routing Information Protocol (RIP) empezar lección
|
|
routers 'learn’ how to forward packets to various networks
|
|
|
|
empezar lección
|
|
each node knows how to reach its directly connected neighbors and if we make sure that all of this knowledge is shared to every node then every node will have complete map of network
|
|
|
|
empezar lección
|
|
node send its link-state information out on all of its directly connected links
|
|
|
Software Defined Networks (SDN) empezar lección
|
|
separates the control plane (decision-making) from the data plane (actual forwarding of packets), software-based controller decides about that
