7.  IP is an address of a Computer on a network.
 task of delivering datagrams from the source host to the destination host
solely based on the addresses.
 Two IP version-IPv4 and IPv6
 IPv4(Internet Protocol version 4)for 32 bits
 IPv6(Internet Protocol version6)for 128 bits
 Type of IP Address
 Static IP Address (Automatically assign)
 Dynamic IP Address (Manually assign)

8.  There are five classes available in IP range
 Class A- 1.0.0.1 to 126.255.255.254
 Class B- 128.1.0.1 to 191.255.255.254
 Class C- 192.1.0.1 to 223.255.255.254
 Class D- 224.1.0.1 to 239.255.255.254
 Class E- 240.1.0.1 to 254.255.255.254
Range 127.0.0.1 is reserved for loopback

9.  Class A- assign large number of hosts
 Class B- assign large to medium network
 Class C- used in small LAN configuration
 Class D- reserved for multicasting purposes
 Class E- for research and developing centre

11.  With the rapid growth of the internet & the ever-
increasing demand for new addresses, the standard
address class structure has been expanded by
borrowing bits from the Host portion to allow for
more Networks.
 There are default standard subnet masks for Class A,
B and C addresses:

12.  The PING (Packet Internet Groper) command
verifies OSI Layer 3 (Network Layer) connectivity.
 The subnet mask is the same for all users on a
specific network.
 Internet routing devices traditionally have been called
gateways
A network gateway is an internetworking system capable of joining
together two networks that use different base protocols.

13.  A choke point of control and monitoring .
 Interconnects networks with differing trust.
 Imposes restrictions on network services.
 only authorized traffic is allowed
 Improve network security & reduce risks to hosts

14. Characterized by protocol level it controls in
 Packet filtering (filter incoming & outgoing data)
 Circuit gateways (large network filter)
 Application gateways (Need separate proxies for each service)
 Combination of above is dynamic packet filter

15.  Internet communication is a accomplished by exchange
of individual ‘packets’ of data.
Each packet is transmitted by its source machine
toward its destination machine.
Connection is actually comprised
Of individual packets travelling
b/w two machine.
If ‘agree’ it means connect or it will
be resend back to the machine.

17.  Firewall cannot prevent Virus and Trojans
from the accessing the internet.
 Mostly virus and trojan are received via e-mail
direct downloading ,etc
 Firewall not really protect the system from hackers
(or any ultra surf)
 Hard to upgrade
 Take up physical space

20.  Multi Protocol Label Switching is arranged between
Layer 2 and Layer 3
 Versatile solution:-speed ,QOS ,traffic management
Security management.

21.  Mechanisms to manage traffic flows of various
granularities (Flow Management)
 Is independent of Layer-2 and Layer-3 protocols
 Maps IP-addresses to fixed length labels
 Supports ATM, Frame-Relay and Ethernet

22. • Label
• Label Edge Router (LER)
• Forwarding Equivalence Router (FER)
• Label Switching Router (LSR)
• Label Distribution Protocol (LDP)

23. • Short fixed length entity
 20-bits label value
 Each label head contain four fields
Label Format

24. • Resides at the edge of an MPLS network and assigns and
removes the labels from the packets.
• Support multiple ports connected to dissimilar networks (such as
frame relay, ATM, and Ethernet).

25. • Is a high speed router in the core on an MPLS network.
• ATM switches can be used as LSRs without changing their
hardware. Label switching is equivalent to VP/VC switching.

27. • An application layer protocol for the distribution of label
binding information to LSRs.
• It is used to map FECs to labels, which, in turn, create LSPs.
• LDP sessions are established between LDP peers in the
MPLS network (not necessarily adjacent).

28. • In MPLS, traffic engineering is inherently provided using explicitly
routed paths.
• The LSPs are created independently, specifying different paths that
are based on user-defined policies. However, this may require
extensive operator intervention.
• RSVP-TE and CR-LDP are two possible approaches to supply
dynamic traffic engineering and QoS in MPLS.

29. • Improves packet-forwarding performance in the network
• Supports QoS and CoS for service differentiation
• Supports network scalability
• Integrates IP and ATM in the network
• Builds interoperable networks

30.  Unknown knowledge of the technology
 Miscommunication of networks still occur
 Near replacement of MPLS technology has to be put
in place of old technology
 Hardware problems
 Better security needs to be implemented so hackers
cannot get into technology
