Tutorial Overview:
Widely deployed broadband is coming to mobile networks in the form of High Speed Packet Access (HSPA), Evolution Data-Optimized (EV-DO)
and WiMAX networks to enable new mobile applications and services. Some of the biggest challenges that will result from this data and
bandwidth explosion will be in the backhaul and aggregation functions that take place in the RAN. Historically RAN backhaul networks
have been voice centric, low capacity and a source of major operational expense for mobile operators. New infrastructure technologies
need to be able to support legacy access types, leverage cost points of newer transport types such as Carrier (Metro) Ethernet and leverage
the high availability, resiliency, and Quality of Service capabilities of IP/MPLS technology.
This tutorial will examine the principal drivers for a new IP/MPLS backhaul transport infrastructure that accommodates the scaling needs
of the evolving mobile networks. Key challenges, options, benefits and tradeoffs are explored for solutions supporting several prevalent
applications. Key existing and emerging industry standards/agreements are referenced.
Tutorial Outline:
- Key issues, enablers and drivers for a transition and the value of IP/MPLS in evolving RAN backhaul architectures
- MPLS fit and operation in the mobile RAN network and the support of end-to-end SLAs, QoS and high availability features
- Reference Architecture
- Mechanisms for LSP Establishment
- Latest pseudo-wire enablers for legacy network traffic migration and their operation over IP/MPLS backhaul networks
- Operations, Administration and Management (OAM) and protection capabilities in RAN IP/MPLS backhaul networks
- Packet synchronization and timing
Intended Audience:
This course is intended for an audience that has a basic understanding of MPLS and mobile backhaul networks.
