It would take over 5 years to watch the amount
of video that will cross global IP networks
every second in 2015.
Internet video is now 40 percent of consumer
Internet traffic, and will reach 61 percent
by the end of 2015.
Globally, mobile data traffic will increase 26
times between 2010 and 2015.
The number of devices connected to IP
networks will be twice as high as the global
population in 2015.

Current State of Utility Communications
Reliability is the number-one criteria for utility communications networks.
Reliability
Communications service
providers face increased
opportunities in utility
communications, but must
meet utilities’ key reliability,
technical and cost
requirements.
Increased
Opportunities
for Providers
Certain key technical factors are
mandatory for safe, reliable and
secure utility operations Extreme high reliability, higher
bandwidth, very low latency,
ubiquitous coverage, tight security
and uninterrupted power supplies.
Mandatory
Technical
Factors
Smart Grid
Evolving
Scope,
Structure &
Technologies
The advent of the smart grid
promises to create a more
uniform set of architectures,
configurations and applications
for utilities in the future.
The scope, structure and
technologies of utility
communications vary widely
from utility to utility – no
single approach to utility
communications is practical.

Key Technical Factors that Impact
Utility Communications Networks
Technical Factor
Situation/Standard
High Reliability
• Crucial to ensure continued functioning of the electric grid
• Require at least four nines (99.99%) in core networks
Higher Capacity or
Bandwidth
• Advent of smart grid technologies and stepped-up needs for complex 2-way
communications driving higher bandwidth architectures
• Extensive microwave links & fiber backbones, but lack spectrum to support widearea backhaul & last-mile access
Low Latencies
• High latencies threaten core operations
• Acceptable level varies and is dependent on specific applications and magnitude of
risk to operational reliability
• Typically in low milliseconds range (10-60ms)
Ubiquitous Coverage
• Safety of field force requires reliable communications
• Need communications systems to cover full geographic expanse of service
territories, particularly wireless
Tight Security Measures
• Two-way digital technologies pose increased risks (i.e. million of endpoints)
• New mandates (NERC-CIP revision & NIST guidelines) driving requirements
• End-to-end protection of the network from physical and cyber attacks
Uninterrupted
Back-Up Power
• Critical to restoring service to the power grid and resuming normal power functions
• Most use combination of multi-hour battery back (8 hrs+) supplemented by
generator back-up powered by fuel sources
Utilities believe that outside telecom providers can not in every circumstance sufficiently meet the key
factors that are mandatory for ensuring the safe and steady operations of the power grid.

Different Implementations of Carrier
Ethernet
Connectionless Ethernet (CLE) and
Connection-Oriented Ethernet (COE)
What is Carrier/Metro Ethernet ?
Augmentation of Ethernet LAN technologies and
standards for use in metro and wide-area networks
Network protection, Remote Fault Management, Performance
Measurements, Classes of Service, etc.
Used to deliver Ethernet (Layer 2) and IP services to
subscribers
Used to build metro/wide area networks (L2 VPNs)

think of Ethernet LANs

Challenges with Connectionless Ethernet
(CLE) in Carrier Ethernet Networks
Non-Deterministic QoS and Traffic Patterns
Variable QoS performance (Packet Delay, Delay Variation, Loss)
• Traffic paths vary due to spanning tree topology changes
Difficult to traffic engineer variable traffic paths
Difficult to Guarantee Bandwidth
Multiple ingress and egress points in the network
Oversubscribed bandwidth (CIR=0) impacts committed bandwidth (CIR≠0)
Difficult to provide High Network Availability
Spanning Tree cannot meet demanding application requirements
No end-to-end service protection
CLE requires technology augmentation to make it “Carrier Grade”
