Why is MPLS important for future telecomunications?
A.-It has growing capabilites
B.- Provides the infrastructure that allows the convergence of today's separate networks providing diferent services to end users.
C.- New transport protocols are needed for high data rate.
B.- Provides the infrastructure that allows the convergence of today's separate networks providing diferent services to end users.
Does MPLS introduce fixed paths for IP packets and QoS capabilites? True or false
True. MPLS introduce fixed paths for IP packets and QoS capabilites
How many MPLS networks are require to support all services? (data, VoIP, TV.)
Only one MPLS network, with the convergence of MPLS, you can have one network supporting all services (Voice, data, TV)
What is MPLS?
MPLS is a networking protocol (defining "label switching technology) it can be seen as an extension of IP
What does MPLS being a toolbox mean?
It has other services to provide all the solutions (IP, OSPF, ISIS, BGP, RSVP, LDP).
What are the other protocols that MPLS has?
MPLS uses (6) protocols:
IP, OSPF, ISIS, BGP, RSVP, LDP
What is LSP?
Label switch paths, these are created on MPLS to move packets across the network.
Why are LSP's created for?
They guarantee that the packets are received in the same order as they were sent.LSP guarantee bandwidth as well so users with a "gold" service will have better quality of service
What is used to separate the traffic from different application on MPLS?
LSP, it helps to separate traffic from different application, for example, we can have the voice traffic in one path and data applications in a complete separated path.
If MPLS can be consider as a toolbox, What are those tools?
It uses (4) tools:
-MPLS/IP
-MPLS/TE
-GMPLS
-MPLS/TP
What is MPLS/IP used for?
IP services and IP forwarding
What is MPLS/TE used for?
It's the traffic engineering extension
Enables support for real time application
Provides QoS
What is GMPLS used for?
Allows to have MPLS is a non-packet networks, such as optical and transport networks
What is MPLS/TP used for?
It is "Transport profile",
Adds transport network feature into MPLS
Adds Resilience (resistance)
Performance monitoring for service level agreement verification
Carrier-grade provisioning capabilities
What are the two benefits of deploying MPLS? (Choose 2)
A.- Replace existing fiber
B.- Replace IP protocol
C.- Convergence of networks
D.- Ability to offer new services
C.- Convergence of networks
D.- Ability to offer new services
What two statements below can MPLS refer to? (Choose 2)
A. - It is a broad term used to describe a set of protocols
C.- It is a networking protocol
What do routers use to forward MPLS packets?
C. - A label
Select two true statements about packet forwarding in IP networks (Choose 2)
A.- End-to-end path is established before packet can be forwarded
B.- Packets sent between two points must use the same path
C.- Packets within the same session can follow different paths
D.- Each router on a path takes independent forwarding decision
C.- Packets within the same session can follow different paths
D.- Each router on a path takes independent forwarding decision
Select two true statements about packet forwarding in MPLS networks (Choose 2)
A.- Packets within the same session can follow different paths
B.- End-to-end path is established before packet can be forwarded
C.- Packets belonging to the same session must use the same path
D.- Each router on a path takes independent forwarding decision
B.- End-to-end path is established before packet can be forwarded
C.- Packets belonging to the same session must use the same path
MPLS allows for running data, video and voice over the same network infrastructure, True or false?
True
Which two protocols below support MPLS deployments? (Choose 2)
A.- RSVP
B.- LDP
C.- DHCP
D.- ATM
A.- RSVP
B.- LDP
MPLS guarantees correct order of packets at receiving end. true or false?
True
What is an LSP?
C. - It is a path established between MPLS devices
Select a true statement about MPLS-TP
B. - MPLS-TP adds OAM and Provisioning functionality to MPLS.
