Monitoring 4G/LTE Technologies:

The Pitfalls and Problems

4GWE Los Angeles, Oct 2010

Wednesday - 10/06/10. 8:30-9:15am

Agenda

Session premise

New devices find their way into old networks, old devices find their way into new networks

and new apps are deployed at breakneck speeds - data usage increases exponentially. But

problems loom large on the horizon. How will voice services be carried? Will these services

play nicely with one another? Will voice quality suffer in the presence of data?

Ethernet Network Monitoring has traditionally been accomplished by a 1:1 relationship

between a tap or switch SPAN port and an analysis device. Tomorrows 4G networks

require a different approach, one which clearly breaks apart the current stovepipe analogy.

4G / LTE Monitoring Challenges

• Flattening of network = New network entities / protocols

• Real time access to user plane & control plane

• Increasing number of proprietary monitoring systems Network Complexity

• Multiple-4G architectures proposed for IMT-Advanced

• 3.5G, LTE, WiMAX, LTE-Advanced, IMS, Femto…

• Circuit Telephony migration to Packet LTE network Evolving Standards

• CAPEX / OPEX constraints

• Revenue / Traffic growth not aligned

• Revenue opportunities through sophisticated SLAs Economics

• 3rd party overlay IP services beyond operators’ control

• New monitoring requirements to ensure QoE

• Rapid troubleshooting / report / repair End User Experience

• Corporate compliance (e.g. SOX)

• Lawful interception Security & Compliance

Network not fully visible: Network Monitoring 1.0

Situation

Tools and probes are deployed across many

interfaces

Access by SPAN or basic network taps

Different tools for different IP services

(VoIP, IPTV, user/control plane, protocol

analyzer, SLA mgmt, IPS/IDS, DPI, etc.)

Challenges

Physical access / blind spots

Network complexity

High management overhead

CAPEX / OPEX – management overhead

Tools scalability / performance (1G / 10G)

Fragmented monitoring creates further

performance and complexity problems.

What is the visibility problem?

Services create revenue only if they are deployed…

Monitoring is essential to make sure the services stay deployed...

Deployed solutions are increasingly

complex.

Traffic on hockey-stick growth curve.

Slow to troubleshoot, manage and

monitor change.

Proliferation of monitoring tools create

physical access contention to SPAN ports.

Traffic volume at high speed (e.g. 10G)

exceeds tools capacity.

Management cost out of control even

as IT budget shrinks.

IP Services

(VoIP, IPTV, VPN, P2P, IM, etc.)

IT Infrastructure

(IDS/IPS, Storage, App Servers, Database, WAN, Sniffer, etc.)

Network Infrastructure

(Ethernet, ATM, Wireless, SONET, etc.)

Network monitoring must be pervasive across

different physical networks and all network layers.

The new paradigm: Network Monitoring 2.0

Decouple analyzer tools from

communication infrastructure

Centralized “tool farm”

Dramatic tools reduction

Views not stovepiped: Ends 1:1

relation between network link

and monitor tool

A traffic capture layer provides

universal network access for

all tools

Single intelligent layer for all traffic

capture needs. Distributed

intelligence & redundancy

Front end traffic grooming /

pre-processing for tools

increases tool utilization

Reduce or eliminate contention

for SPAN ports

Simplified & centralized management

Industry Benefits

Discover where latency / delay are introduced

Understand how apps / services are affected

Reduce churn / improve customer satisfaction

Industry Problems

Latency / delay in network

Apps / services are not working correctly

Network overload, unexpected operation

Network Latency & QoE Use Case

Understand how packets are delayed / jitter is introduced

Reduce application and service outages, adhere to SLAs

CONFIDENTIAL and Proprietary VSS Monitoring, Inc. © 2009

Industry Problems

Backhaul congestion and dropped packets

Backhaul traffic prioritization delay

Latency, microbursts and network overload

Backhaul Use Case

Find / understand issues in backhaul function

Gain timeline advantage on diagnosis and repair

Industry Benefits

Keep existing analytic tools

Preserve investment in existing infrastructure

Analyzers see only the traffic they need

CONFIDENTIAL and Proprietary VSS Monitoring, Inc. © 2009

Industry Problems

Too many feeds / tap points

Too much data and unwanted traffic

Upgrading to new analytic tools expensive

Aggregation and Speed Conversion Use Case

Obtain traffic network-wide independent of feed / speed

Aggregate traffic to minimize demands on network

Industry Benefits

Determine congestion, find dropped packets

Discover latency sources, traffic policy

Aggregate multiple feeds to a single feed

CONFIDENTIAL and Proprietary VSS Monitoring, Inc. © 2009

Industry Problems

First time voice is packetized

Mixing traffic types causes bursty networks

Unknown traffic interactions

Traffic Management Use Case

Understand which traffic types are causing issues

Rationalize network resources to meet traffic usage patterns

Industry Benefits

Discover traffic usage patterns

Correctly apportion network bandwidth

Reduce latency / dropped packets

CONFIDENTIAL and Proprietary VSS Monitoring, Inc. © 2009

Industry Problems

Traffic is not aggregated in a session aware manner

Traffic is lost via what look like dropped packets

Problems are hidden, hard to get at the real issues

Session Aware Load Balancing Use Case

Present specific traffic types to correct

analysis device

Load balance streams in session aware

manner

Industry Benefits

Find the real issues on your network

Stop dropping packets in your analysis path

Proactively address the problems in a session aware

manner

CONFIDENTIAL and Proprietary VSS Monitoring, Inc. © 2009

Industry Problems

Network visibility is local, not network wide

Existing aggregators are not session aware

Packets are being lost by the analysis function

Network Wide Visibility Use Case

Monitor entire network from single location, remotely or multiple locations

Load balance traffic across available in-house analysis tools

Industry Benefits

Session aware streams are constructed

Monitor entire network from single / multiple locations

Stop losing packets, detect and fix problems faster
