BENEFITS OF IP/MPLS IN THE ACCESS

1. Network virtualization 2. Densification and scalability 3. New revenue generating services 4. Faster end-to-end service provisioning 5. Preparing for VoLTE 6. Utilizing the X2 interface 7. Unified transport 8. Intelligent backhaul utilization

NETWORK VIRTUALIZATION

Todays cell site have 2G, 3G, 4G services as well as WiFi, Synchronization devices, broadband services and more.

MPLS L2VPN, VPLS and L3 VPN allow for virtualization of a physical network into logical networks.

Advantages: Simpler network operation Easier debugging and troubleshooting

DENSIFICATION & SCALABILITY

With LTE theres a shift from coverage to densification in order to support more users per cell and higher throughputs.

Femto cells, WiFi access points and CCTV are also being introduced at the cell site.

A layer 2 transport will not scale to support the thousands of network elements in the access.

As part of its new "Project VIP" network upgrade, AT&T is adding 10,000 new large cells and 40,000 small cells in urban areas. By shrinking the size of each cell, AT&T can support more users per square mile. That means fewer blocked calls and more consistent data speeds in dense cities.

NEW REVENUE GENERATING SERVICES

Operators must look at new sources of revenue such as: Customized services (guaranteed throughput, HD streaming, video

calling) Enterprise services RAN sharing

Seamless MPLS

FASTER END-TO-END SERVICE PROVISIONING

The network is the bottleneck of service delivery Services (virtual machines) in the datacenter are turned up in minutes, the

network needs to catch up! A seamless MPLS architecture drastically reduce network provisioning time Ability to manage layer 1, Layer 2 and Layer 3 from one platform.

PREPARING FOR VoLTE

MPLS Traffic Engineering guarantees bandwidth and SLAs for voice traffic.

MPLS millisecond fast failure recovery mechanisms eliminate failure impact on voice traffic.

MPLS is inherently more secure than IP networks. IPSec could also be used for encryption.

UTILIZING THE X2 INTERFACE

X2 is key challenge going forward High capacity: up to 10 percent of an eNodeBs total traffic

Low latency

MPLS enables scalable X2 network design

eNodeBs on different subnets, routing is required between Layer 2 domains for complete X2 solution

Flexible and Scalable as the network grows

UNIFIED TRANSPORT

MPLS provides a single converged transport solution for all access technologies. Plus MPLS is generally deployed in core networks so MPLS in the access is just an extension of existing network transport architecture

CAPEX and OPEX savings. No need to maintain multiple transport networks!

MOMENTUM BEHIND IP/MPLS TO THE CELL SITE

13

Operator realization that MPLS is coming

of MNOs say they are likely to need L3 in access network in 3 years

74 % Top operators in all sectors committed to MPLS at cell site

Key vendors advocating MPLS at cell site too

Analysts forecasting strong demand for Microwave Router

SDN not coming to backhaul any time soon Dont believe the hype of SDN widespread production deployment outside the data center will not begin for another two years Jennifer Pigg, Yankee Group

COSTLY COMPLEX MANAGEMENT POOR PERFORMING

NETWORK

AVIAT NETWORKS

3 KEY CHALLENGES STILL EXIST

1. Too many boxes (L3 + L2 + L1) Costly, poorly performing network, complex management

2. Packet switched technology is not well understood by

transmission department TR engineer vs. network engineering Difficult to design, deploy, and maintenance

3. Service delivery still too slow

Not adaptable to business needs especially enterprise

ADDRESSING CHALLENGES: Technology convergence:

1. MPLS-Transport Integration (Microwave Router) Microwave router includes fiber and MW solution

2. Efficient service provisioning from a single management

platform Enable optimum IP/MPLS design and implementation with real time network performance and intelligence
