What is the Outlook in the Telecom’s Market?



A very Challenging Perspective

Satellite Mobile Revenues and profit are

What has to be done? – Reduce Costs

 Replace legacy, rather expensive network
components with cost-saving technology based on
the Ethernet standard
 Optimise your network's throughput and apply
packet-based transport instead of line-oriented
transport
 Standardise the network technology
 Multi-service access platform for a wide range of
services out of one network element
 Introduce the new technology but keep initial
investments as low as possible



What has to be done? – Keep Existing Sources of Revenue

 Replacing line-oriented transport to a packet-based
one requires to adapt the data of legacy services
like
 E1
 POTS
 ISDN
 Gateways between TDM and Ethernet have to be
implemented
 V5.2 to VoIP
 E1 to Ethernet
 Ethernet over SDH
 Subscribers can still use their existing terminal
devices



What has to be done? – Generate new Sources of Income

 Surcharge for added value
 increasing bandwidth
 higher availability of services
 New sources of income due to new services
 IPTV
 Video-on-Demand
 PVR/DVR
 Video Conferencing
 Bundling of Services

Increasing

IPTV with Unicast

TV viewer requests TV channel

Server sends video stream

Every TV viewer has his own dedicated video stream

Live Broadcast

HDTV: >6 Mbps

<150 HDTVs per Gigabit Ethernet Interface

Unicast is Highly Inefficient to Broadcast TV



Multicast/IGMP Snooping Improves the Network Efficiency

TV viewer requests TV channel

Server sends video stream

If other viewer requests the same channel
the network multiplied the video stream
Live Broadcast

HDTV: >6 Mbps

Unlimited Number of TVs
Over 80 HDTV Channels per Gigabit Ethernet

Highly Efficient Delivery of Broadcast TV



Security on MileGate

 Hair-pin forwarding
 Only frames with MAC destination address of the
broadband network gateway are forwarded
towards the network
 Hair-pin forwarding (peer-to-peer traffic) is
prevented
 MAC address spoofing
 The source MAC address is validated against the
interface
 Source MAC spoofing is prevented
The use of Ethernet as an
aggregation technology  MAC address flooding
presents new security  Number of MAC addresses learnt on one port is
challenges limited
 Source MAC flooding is prevented



Security on MileGate

 MAC Address Translation
 Avoid MAC address duplication network wise
 Filtering
 List of acceptable MAC destination addresses in
upstream direction
 Only frames with valid destination addresses are
forwarded
 Denial of Service (DoS)
 Access Control Lists limit the number of multicast
channel per user and provide protection against
DoS attacks

Quality of Service – Priorities and Queuing Methods

 Prioritise critical traffic (voice, video) over
"uncritical" traffic (mail, web)
 Different queuing methods
 Strict Priority
 WFQ (Weighted Fair Queuing)
 WRR (Weighted Round Robin)
 Classification by
 CoS marking
 Ingress port
 DiffServ code points (DSCP)
 8 priorities level in CoS mapped to

UNEM KEY Features & Functionality

 Graphical & hierarchical network presentation
including sections
 Configuration of network elements and their units
 Fault management – locating of alarms down to
sub-unit level
 Alarm Forwarding via E-Mail
 Performance management – retrieval, storage
and export of performance monitoring data
 Network wide software download
 Synchronisation map – displays the clock signal
distribution flow in the network
 Security management – capability to define
different operator classes & access rights based
on user profiles
 Inventory Management – HW & SW information
stored in UNEM database and updated
automatically, export via XML file
 UNEM networking package for UMUX –
providing end-to-end circuit provisioning
