implementing an effective online authentication scheme in practice faces many challenges systems with highly sensitive data often require multifactor
authentication in pppppp can support authentication operations at the beginning of a connection in some cases reauthentication is
transition phases a ppp connection goes through phases which can be shown in a transition phase dead in the dead phase the link is
ipv6the internet engineering task force begin the effort to develop a successor protocols to ipv4 in the early 1990 is an
switching via an interconnection networkthe switching techniques overcome the bandwidth limitation of a single shared bus this
switching via memorytraditional computers with switching between input and output being doen under direct control
router componentsas noted in the previous a router consists of a of input interfaces at which packets arrive and a set of output
advantages of ospfospf an is having different advantages these are as followsospf is an open standard supported by many vendorsospf
ospf open shortest path firstopen shortest path first is a routing protocols developed for internet protocols networks by the
advantages of ls over dv algorithmthere are a number of advantages to link state protocols especially when compared to the
routing tablea routing table has columns for at three types o information the network id the cost and the id of
sharing information to understand how distance vector routing works examine the internet shown in the clouds represents
in formation sharing at regular intervalsfor example every 30 seconds each router sends its information about the whole
routing tableeach router now uses the shortest path tree to construct its routing table each router uses the same algorithm and
shortest path the dijkstra algorithms four steps to discover what it called the shortest path tree athe algorithm beings
dijkstra algorithmsto calculate its routing table each router applies an algorithm called the dijkstra algorithm to its state
initialization imagine that all routers in our sample internetwork comes up at the same time each router sends a greeting
link state packetwhen a router floods the network with information about its neighbourhood it is said to be advertising the basis
routing principlethe principle criterion of successful routing is of course correctness but it not only criterion you might prefer to
network service modelthe network service model defines the characteristics of end to end transport of data between one edge
routersthe network layer also called layer3 manages device addressing tracks the location of devices on the network and
switchgenerally called as two layer switch it performs on physical and data link layers it is a bridge it has
advantages of bridgesby forwarding frames only to the segment where host resides a bridge server the following
