VPN, Frame Relay; Network Management
VPN Technology

This creates a private and secure network such as the internet. This will keep your internet
activity private and secured to avoid displayed or seen by internet providers and some other
users. Through this, the geographical location of your IP address changed in order that it will not
trace and at the same time you can access those sites that have been blocked by your country,
this is because your IP is spoofed.
Benefits of VPN
•

Gives enough security

•

Restricted Access

•

Better connectivity

•

Privacy protection such as bank info, downloads, and passwords

•

Can unblock any websites from anywhere

•

Get complete Wifi security

•

Enjoy anonymous browsing

•

Could stop hackers and increased the level of your internet connection

•

Change your identities online such as your country location and much more

•

No technical experience and could easy to use and connect

•

Reduce cost

•

Change IP address

•

Remote control and share files

Components of VPN
Running alongside to the other software on a particular shared server. This case is not typical and
it could enter the reliability and security of the VPN at risk.

Characteristics of Secure VPN
The secure VPN has the reliable characteristic that has proven effective. Many people have
satisfied in using VPN Technology because it has several characteristics on which it provides
enough security and fast connection. Technology users could assume their network privacy such

as connection, credential details, sharing information, and mechanism security. VPN is
considered as security mechanism because through this, there is an encryption on which it
provides server authentication in order to avoid any unauthorized users that will access your
VPN. It has its confidentiality that means, anyone who tried to access the information which is
private, can only view or see the data that was encrypted. Many organizations who handled
corporation of communication uses Virtual Private Network because it gives them efficiently and
convenience services and privacy.
•

It support multiple protocols

•

Point to Point connection

•

Encrypted traffic

•

Remote site is authenticated

Frame Relay
Frame relay is a standard wide network technology that particularized the physical and data link
layers of digital communication channels with the use of a packet switching methodology. It also
used for the different context of another network interface. It was developed in order to have a
high data rates and low rates error on modern WAN links.

Benefits of Frame Relay
May people have been using the frame relay for communication aspects. Frame relay has many
benefits;
•

Lower the cost of Better Bandwidth Utilization and Ownership.

•

Reducing the network manager's complexity

•

Reduces the number of dedicated devices

•

Savings private lines

•

Users will experience personnel plentiful in a workforce.

•

"Multiple layer 3 protocols are supported"

•

It has an ability to interconnect international both local and national.

Virtual Circuit and DLCI number

Virtual - circuit packet that similar to circuit switching. It was using a "call request" and each of
the nodes was incurs a delay. It was accepted once the "call accepts packet". The establishment
of the virtual circuit message was delivered into a packet.

Frame Relay uses Data Link Connection Identifier (DLCI) in order to "statistically multiplex frames". A
Virtual circuit composed only with a single (DLCI) in their leader and there is no destination and sources.
The DLCI number, on the other hand, have only local significance. Those DLCI numbers are not included
to some of the routers, but other routers could use similar DLCI numbers without experiencing any
issues of connectivity.

Frame Relay Topologies

Frame relay topologies include the following:
Full Mesh ( multiple subnets)
Full Mesh ( single subnet)
Hub-Spoke (multiple subnets)
Hub-Spoke (single subnet)

Frame Relay Address Mapping

The frame relay dynamic mapping depends on the Inverse ARP in order to connect and resolve a net hop
homework protocol address to the DLCI local value. A static frame relay map could be used for a
situation that the router from the other side, will not backing dynamic Inverse ARP in a certain network
protocol.

Configuration of Frame Relay

VPN, FRAME RELAY; NETWORK MANAGEMENT
There are several steps and ways in creating frame relay connections using the different type of
hardware configurations.
•

The access servers and router are connected to each other through the frame relay switch

•

The access servers and routers are directly connected to the (CSU-/DSU), then connects to the
frame relay switch as it shown below;

Configuring a Frame Relay Router Address Connect Broadcast

The minimum frame relay is consist of a single command;
•

Router config (# interface serial 0)

•

Router config ( # encapsulation frame-relay)

•

Router config (# no shutdown)

A Cisco router is active acted with this single command as a frame relay DTE device. The
interface is enabled and well administratively managed as well as the frame relay demonstrated
the configured DLCIs to the router and the remote network layer will be addressed to the DLCIs
local. It adds additional PVC between the satellite 2 and 1. The map statement of configure
frame relay and configure "point-to-point subinterfaces".

Four-port Secure Ethernet VLAN switch Supporting SNMP and RMON And Management
Information Base object

A multi-port switch is given and having an Ethernet exchanging environment series for
exchanging and interfacing of gadgets system and incorporates no less than three ports. The fourport secure Ethernet VLAN switch supporting SNMP and RMON. The system administration
module is working just to indicate with SNMP, and the checking of the module just to indicate
with RMON. The switch is very secured by system component on which is the piece of a system
gadgets. The switch is secured and situated inside one of ATMs of ATM LAN. One of the ports
is associated with a switch, one of the ports is in ATM or ATM LAN, and one of the ports is
associated with client LAN. The client LAN is identically incorporated in no less than one
money enlist. The switch is organizing the ATM-LAN port and switch port to one VLAN and

accommodating the client LAN and the switch port into another VLAN. This invention provides
convenience to the users in any ATM machines on which it was providing enough responses that
the system and switches are well organized and corresponds with the flow of the system even in
any system gadgets. But, there are weaknesses of the RMON in this presentation. The RMON,
due to the adding and separating the information data network connection, there is a less costeffective for the proprietor. It sometimes collapses when the ATM-LAN failed to come into the
customer LAN. But this case is very rare and nothing to be worried about. Aside from weakness,
the RMON of this presentation has also strengths in which it allows the system perfectly
response and accommodates the inquiries. RMON administration or having a network
monitoring improves the performance of tuning, billing, troubleshooting, and planning. It is a
standard form of Internet specification (RFC 1757). On the other hand, the management
information base object is a network device object on which the method is detailed of
configuration management and tasking of hardware that attached with perfect mapping of
internal device objects to RMON or SNMP protocol of a certain network device.
