Exploring IPv6

for LTE Networks

Instructor Led | Duration:
2

Day
s

| Course Number: LTE_202

The roots of the current Internet stretch back over twenty years to its beginnings in academic institutions. The fact that it

has been able to adapt and scale to
today’s global network is a testament to the solid design principles used in its creation. How
ever, as the number of Internet nodes continues to grow and new
demands are
expected

on it
as we evolve our
2G/3G

networks to LTE
, the current IPv4
-
NAT architecture no longer suffices and we must consider a transition
to an updated protocol. This course ex
plores the IPv6 protocol, which brings not only a vast address space to address millions of billions of network nodes but
also a bag of new tricks. Streamlined and simplified, IPv6 incorporates a number of companion protocols into its core specifi
cation. T
his course covers these
general topics as well as the adop
tion of IPv6 in LTE Networks
.



Intended Audience

This is an introductory course
and does not assume any previous
knowledge of IPv6. It is suitable for wireless

professionals who want to gain
awareness of IPv4’s real limitations, the key issues with IPv6’s new
capabilities, and how to transition the networks.

The course assumes basic
k
nowledge of LTE EPC and the LTE Network Architecture and functions
.


Learning Objectives

After completing this course, the student will be able to:



Sketch LTE
-
EPC network architecture and identify the role of IPv6



Analyze the limitations of IPv4 networks

Describe wireless mobility solutions in IPv6



Identify the impact of IPv6 on related protocols



Describe the
use of
dual stack IPv4/
IPv6 in
LTE N
etworks



Discuss the different UE IP allocation schemes



Describe
some IPv4 and IPv6 interworking scenarios
