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)
Internet Protocol
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
IP Address Classes
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
IP Address Classes Details
IP Configuration
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:
Subnetting
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.
Verify Connectivity
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
Firewall
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
Classification Of Firewall
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 travellingb/w two machine.If ‘agree’ it means connect or it willbe resend back to the machine.
Firewall Works
List of Filtering Rules
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
Drawback of Firewall
MY PROJECTMulti Protocol Label Switching
Multi Protocol Label Switching is arranged between Layer 2 and Layer 3
Versatile solution:-speed ,QOS ,traffic management Security management.
Multi Protocol Label Switch (MPLS)
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
Characteristics
• Label
• Label Edge Router (LER)
• Forwarding Equivalence Router (FER)
• Label Switching Router (LSR)
• Label Distribution Protocol (LDP)
Components
• Short fixed length entity 20-bits label value Each label head contain four fields Label Format
Label
• 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).
Label Edge Router (LER)
• 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.
Label Switch Router (LSR)
Position of LER & LSR
• 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).
Label Distribution Protocol (LDP)
• 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.
Traffic Engineering
• 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
Advantages
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
Disadvantages
