The document discusses TeleMakkaräna's network transformation journey towards fixed-mobile convergence. It summarizes: 1) TeleMakkaräna implemented a Juniper MPLS backbone and metro network in Phase 1a, reducing OPEX by 20% and outages to zero. 2) In Phase 1b, a common Juniper control complex was introduced for converged authentication, authorization, and accounting. 3) A cost modeling tool showed that migrating TeleMakkaräna's mobile backhaul to a Juniper IP/MPLS solution over Ethernet could save over 45 million in CAPEX and OPEX over 5 years, a 32% savings compared to the existing TDM

Welcome to the Kingdom of Makkaräna !Welcome to the Kingdom of Makkaräna !
Makkaräna
The Kingdom of Makkaräna is a country in South-East Central Europe, North
of the Balkan Peninsula, on the Lower Danube, within and outside the
Carpathian arch, bordering on the Black Sea [1]. It shares a border with Hungary
and Serbia to the west, Ukraine and the Republic of Moldova to the northeast,
Romania and Bulgaria to the south. It is a recent member of the European
Union and hosts its holiday dacha, as well as those of other major international
organizations, including NATO [2].
Makkaräna covers an area of 130,528 square kilometers (11,787 square miles)
and has a population of about 21.7 million.
Throughout history, Makkaräna has been a favorite destination of emperors and
war-lords, who typically brought huge crowds with them. Examples include
Alexander the Great, Djengiz Khan and more recently Michael Jackson.
Currently, Makkaräna is a happy feudal kingdom, led by King Jaroslaw XIII.
Makkaräna has the 11th largest territory and the 17th largest population among
the European Union member states. Its capital and largest city is Makkaroon.
The currency is the Makkaräna Marbel (MM), pegged 1-to-1 to the Euro since
2006.
King Jaroslaw XIII has a wife, Queen Ezmiralda, and one daughter, Prinzess
Sylviya.

 Prinzess Sylviya, CTO TeleMakkaräna:
• “After introducing the Juniper MPLS
backbone and metro, we were able
to shave 20% off our network
OPEX budget, and reduce outages
to almost zero.”
In a recent survey, 82% of customers
running Juniper Networks JUNOS as well as
other router operating systems, considered
JUNOS more efficient than other operating
systems in one or more categories*

What’s next on TeleMakkaräna’s agenda?What’s next on TeleMakkaräna’s agenda?
 Develop Roadmap to Fixed-Mobile Convergence
• Step 0: bundling
• Step 1: the Home Zone
• Step 2: UMA
• Step 3: Femtocells
• Step 4: IMS
 Is the network able to cope with all this?
• eg. how can we guarantee voice quality across the network
 Is the OSS/BSS able to cope with all this?
• lots of customer databases
• eg. AAA: user denied on DSL, still gets access on WiFi hotspot
 Let’s consult our vendor partners…

Why MPLS in the RAN?Why MPLS in the RAN?
 MPLS is flexible
• Technically: backhaul 2G, 3G, LTE, WiMAX, etc. on one network
• with mix IPv4 and IPv6 traffic
• and support multiple connectivity models
• Operationally: support different deployment scenarios
• topologies, single domain, multi-domain, wholesale, …
• Future-proof : open to new connectivity models, new applications
• as proven in wireline networks
 MPLS is powerful
• QoS guarantees where required, bandwidth efficiency where not
• resilience: fast reroute, multihoming
• multipoint, eg for video multicast or clock distribution
