Consideration in Building Multi Service Network
Services type and attributes (data, video, voice, etc)
Services Requirements– Protocol Requirements (IP,non IP, FR,ATM,etc)– Security requirements (total separation, authentication, etc)– High Availability requirements (4 9, 5 9 ?)
Charging

Internet Access NC NC NC
Business VPN 1~10 Mbps <0.540ms

VoIP <64kbps <10E -2<200ms
RTD

How to meet Service Network AttributesReliability/PER attributes :
– Related with Transmission Type– VSAT PER < MWAVE < DSL < FO
Bandwidth attributes :– Related with transmission capacity – VSAT ~ kbps to 2 Mbps– Mwave ~ 54 Mbps – DSL ~ 2 to 10 Mbps– Fiber Optic ~ 40 Gbps
Delay Attributes :– Related with transmission type, distance and bandwidth availability, processing and queueing– VSAT ~ 500ms– MWAVE ~ 10 ms– FO ~ < 1ms

How to Calculate Delay ?
P1 Q1 P2 Q2P3
Q3P4
Total Delay : P1+Q1+P2+Q2+P3+Q3+P4
Q : processing and Queuing delay is around uS in cisco routersP : Propagation/Serialization is the most parts, depends on
transmission and bandwidth availability
© 2006 Cisco Systems, Inc. All rights reserved. Cisco ConfidentialPresentation_ID 17
Propagation Delay (example)
Media : MicrowaveTransmission delay : 10ms Bandwidth : 2 MbpsPackets size : 10 Mega bitNumber of Hop : 4 hopsPropagation delay: 10/2 x 10ms x 5 hops : 250ms

Service Requirements (typical)
IP Based Service , such as business application, VoIP, IPTV, HSI, etc
Non IP Based Service, such as mobile backhoul, ATM based service or FR based Service
L3 based service, such as business application, HSI, VoIP, etc
L2 based service, LAN trunking , flat network, IPX, etc
5 9 HA requirements , such as mobile backhoul

What Does Ethernet as a LAN/MAN/WAN Transport Offer?
Ethernet becomes the ubiquitous interface: single technology for LAN, MAN and WAN
Efficient packet-based infrastructure: IP friendly
Cost effective interface with flexible bandwidth offerings: 10/100/1000/10000 Mbps
Geographical independence: Ethernet over Optical, IP or MPLS
