Emerging Trends
• Convergence of telecom, broadcasting and media sector
is one of most significant phenomenon
• Deployment of IP based networks by telecom operators
primarily for reducing CAPEX and OPEX
• New managed networks and technologies like MPLS are
getting more popular
• Burden of network management is being shifted to
services providers from end users

Emerging Trends
(contd.)
• Such networks are capable to provide guaranteed
quality of service resulting in efficient use of
available bandwidth and still have the very simple
network architecture
• Variety of services like virtual private networks, peerto-peer file transfer, video conferencing etc. can be
provided using such networks.

Overview of Managed Networks
• The recent trends suggest a shift from point-to-point
connectivity to point-to-multipoint managed connectivity

Some of the managed services being offered by service
providers under different tariff packages are:
Secured IP services
Managed Data Network Services
Managed Internet Services
Transactional Routing services
Enterprise hosting service
VPN and VPN Tunnel service
Enhanced VPN service

Benefits of Managed Networks
Telecom Regulatory Authority of India
• Higher network efficiencies and reduction in CAPEX
and OPEX, as no need to have separate leased lines
for
Internet
and
normal
data
connectivity
requirement at multiple locations.
• Supports multiple QoS levels for voice, video and
data traffic.
• Enable high data intensive services to the enterprise
and corporate users including IP-VPN, MPLS-VPN
etc.
• Better security, flexibility and scalability, simplicity,
manageability and better traffic engineering

Parameters for Managed Connectivity
•
Number and type of customers sites (Managed or
Unmanaged)
•
Type of protocols being used and to be supported
between customer’s edge router and the service
provider’s router. ( Existing and future services)
•
Class of Services support required for different
type of traffic to be carried over the network.
•
Internet
connectivity,
content
filtering
with
conditional access list

Major Pricing Components of MPLS based
networks
• Local access
• MPLS port charge: MPLS platform provides IP MPLS
Ports capability of different speeds such as 56k to T1/E1,
E-3, STM1/OC3, STM1/OC3, STM4 etc.
• MPLS Class of Service charges

QoS: Prioritize by Traffic Type
• Level 4: Real time (voice, interactive video)
• Level 3: Business interactive ( Systems Network
Architecture [SNA], SAP etc)
• Level 2: Real time (streaming video, network
management)
• Level 1: Business LAN-to-LAN (Internet Web, IBM Lotus
Workplace, Novell GroupWise, and others)
• Level 0: Best-effort data (Simple Mail Transfer Protocol
[SMTP], FTP, Internet Web, and others)

Pricing with different Class of Service
• Single CoS Price
• No CoS Surcharge
• Class of Service Surcharge
• Differentiated CoS Pricing
For each CoS, the provider meets specified
criteria for latency, jitter, and packet loss etc.

Service Level Agreements
• ITU Rec. M.3350 has defined Service Level
Agreement as follows:
“A formal negotiated agreement between two
parties. It is a contract that exists between the
Service Provider (SP) and the Service Customer
(SC). It is designed to create a common
understanding about service, quality, priorities,
responsibilities etc. SLAs can cover many aspects
of the relationship between the SC and the SP,
such as performance of services, customer care,
billing, service provisioning, etc.”

Parameters incorporated in the SLAs
•
•
•
•
•
•
•
•
•
Access Installation time
Port connection and activation time
% packet losses
Round Trip Delay
Jitter
Site Availability per month
Maximum Time to Repair
Cumulative down time for contract period
Penalty/ Compensation for breach of SLA
In practice SLAs are not cost based while price
prescribed through tariff order are generally cost
based.
MPLS SLAs will require a broader range of service level
metrics as compared to the solutions based on

traditional technologies
