Mobile Broadband Trends Optimizing and scaling the data and control planes
• VAS to reduce bandwidth/costs (e.g., video optimization) and for
new revenue-generating services (e.g., security, parental control...)
• Intelligent traffic steering and HTTP header enrichment
• WiFi offload and mobile data offload (SIPTO, LIPA)
Optimizing and enriching the data plane
• Build cost-effective infrastructure for AAA,
PCC, and IMS
• IPv4 address exhaustion (NAT44)
• IPv6 transition (NAT64 / DNS64)

Mobile Data Plane—Increasing Complexity
URL Filtering
WAP Gateway Video Optimization
• GGSN does APN-based segmentation
• Aggregation router does policy-based routing (e.g. Port80-based forwarding)
• Traffic segmented in VLANs to VAS layer
Static and inflexible traffic segmentation
Transparent
Caching
• Complex architecture, hard to scale
• Results in high CapEx and OpEx on VAS side
• Difficult to add new services (inflexible, requires changes in GGSN, VLAN management…)
• Everything is mostly HTTP/S now!

Cloud Services / Data Centers CSPs increasingly use
network assets to target
data center service
opportunities
Ovum forecasts the public cloud computing infrastructure-as-a-service (IaaS) opportunity at $1.6bn in
2011, growing to $15.0bn in 2016. Of the $1.6bn in 2011 revenues, no more than 10% was earned by
communications service providers (CSPs). Using their data center and WAN infrastructure assets,
CSPs have a significant new opportunity to compete against their IT rivals, including data center
specialists, and capture more of this growing revenue source.
Data centers are becoming a
much more critical piece of
‘telecom’ infrastructure
Service providers expanding data
center offerings on quest for new
revenue

To provide users with the best access to and experience with a
service without the user needing to know or care about how the
service is delivered or the complexity involved.
What Is the Goal of a Cloud?
Fact: Providing a cloud is complex.
© F5 Networks, Inc.
23 © F5 Networks, Inc.
F5’s vision is to make the development, operation, and use of a
cloud as easy as possible so the provider can connect their
users to their services.
This means:
• Getting users to the right part of the provider’s cloud.
• Providing the ability to control access in the cloud.
• Providing layers of security within the cloud.
• Providing the means to make the supporting cloud infrastructure
as efficient, dynamic, and resilient as possible.
• Providing the best possible user experience.
