This report considers the global trends in mobile broadband traffic growth as well as the
possibilities of the new LTE architecture. It describes how mobile network planners look at
the potential for feature distribution out from the center network toward
the aggregation
layer of the backhaul, and even the cell site at the very edge of the network. The report
examines the case for distributing different types of functionality
-

ranging from the 3GPP
-
defined GGSN, EPC and PCC to firewall, content caching and

DPI
-

which are becoming
increasingly important with the growth in mobile data traffic


Report Highlights:




Key Findings:




Many fixed networks have yet to complete the distribution of broadband remote
access server (B
-
RAS) functionality



CTOs and
network planners are more committed to a more distributed all
-
IP mobile
network, especially in conjunction with the rollout of LTE



There are a number of substantial barriers to rapid evolution toward a more
distributed mobile network architecture



Bearer pl
ane
-
orientated capabilities


such as LTE’s packet gateway (P
-
GW)
function, deep packet inspection (DPI) and content caching


are among the
features mobile operators are most likely to push out towards the edge



Distributed caching is attracting a lot of a
ttention, and may form part of a feature
distribution in years to come



From a design and operational perspective, distribute caching is a capability that
needs to be overlaid on top of the underlying IP network


The report
discusses
the outlook for specific functions and features, challenges for
vendors, and
concludes with detailed vendor analyses.
