1 TrueCircuit Technology A fast, low cost, and adaptable way to distribute Video, Audio, Control, and Metadata via widespread IP networking technology SMPTE Presentation Pasadena, CA October 18-21, 2000 Carsten Baumann - Director of Product Management / Leitch Dr. Yendo Hu - Vice President / Path 1 Network Technologies Inc.
2 Agenda Different Network criteria's The history of Ethernet, IP, and TCP/IP Advantages of IP/Ethernet Disadvantages and Challenges of IP/Ethernet Quality of Service (QoS) What is TrueCircuit? Market Trends and Applications Summary
3 There are three main criteria s of how to select the right network technology Make sure the network offers the solution to your problem Evaluate the trade-off of the technical concept proportional to price Pay only as much as necessary
4 Today there are fife important different networks available ATM IEEE 1394 (Fire Wire) Fiber Channel IP XY-Router
5 Different Networks are used for different applications Network Comparison Poor Good Excellent ATM IEEE 1394 Fiber Channel IP Based XY-Router Scalability QoS Price Security Reliability Bandwidth
6 TrueCircuit enables IP networks to be used more effective Network Comparison - TrueCircuit enabled Poor Good Excellent ATM IEEE 1394 Fiber Channel IP TrueCircuit XY-Router Scalability QoS Price Security Reliability Bandwidth
7 Agenda The history of Ethernet, IP, and TCP/IP Advantages of IP/Ethernet Disadvantages and Challenges of IP/Ethernet Quality of Service (QoS) What is TrueCircuit? Market Trends and Applications Summary
8 Ethernet and IP are based on research funded by ARPA Back in the mid 70s Ethernet, IP, and TCP/IP were developed based on research funded by ARPA (Advanced Research Projects Agency) University researchers were encouraged to adopt these new protocols to exchange information ARPANET and MILNET existed at this time No provisions were made for Quality of Service or security
9 Agenda The history of Ethernet, IP, and TCP/IP Advantages of IP/Ethernet Disadvantages and Challenges of IP/Ethernet Quality of Service (QoS) What is TrueCircuit? Market Trends and Applications Summary
10 IP/Ethernet offers several advantages IP/Ethernet is well known and widely used IP/Ethernet is the backbone of the Internet Billions of dollars are being invested in developing IP/Ethernet IP/Ethernet is the revenue generator for the future Multiple vendors / low cost IP/Ethernet is the focus for all future commerce
11 IP/Ethernet offers huge bandwidth at affordable cost Standard Bandwidth Bandwidth / Cost 10 Base-T 10 Mb/s 100 Base-T 100 Mb/s 1000 Base-T 1 Gb/s Base-SX 10 Gb/s x10 the bandwidth / x2 the price x10 the bandwidth / x2 the price x10 the bandwidth / x2 the price??
12 IP is more cost efficient compared to ATM and other networks An 8 port Gigabit Ethernet switch costs between US $ 10-12k An 8 port OC-12 (622Mb/s) ATM switch costs between US $ 70-80k
13 Agenda The history of Ethernet, IP, and TCP/IP Advantages of IP/Ethernet Disadvantages and Challenges of IP/Ethernet Quality of Service (QoS) What is TrueCircuit? Market Trends and Applications Summary
14 Ethernet is defined as Best Effort Delivery mechanism Hardware provides no information to the sender about whether packets have been delivered Ethernet access control is distributed and called Carrier Sense Multiple Access with Collision Detect (CSMA/CD) Almost no Quality of Service (QoS) is provided
15 Agenda The history of Ethernet, IP, and TCP/IP Advantages of IP/Ethernet Disadvantages and Challenges of IP/Ethernet Quality of Service (QoS) What is TrueCircuit? Market Trends and Applications Summary
16 QoS determines the performance properties of connections and defines the value of the service Five parameters are important for offering QoS Bandwidth Latency Time Jitter Order 1 Loss t t t t t t t t t t t t t t t t t
17 TrueCircuit offers extreme high QoS Fully compatible with standard IP equipment Provides IP QoS equivalent to ATM Creates Virtual Circuits Low Jitter Guarantees the right order, No Loss of packets Low Latency (5ms guaranteed), High Bandwidth Utilization (up to 94%)
18 Agenda The history of Ethernet, IP, and TCP/IP Advantages of IP/Ethernet Disadvantages and Challenges of IP/Ethernet Quality of Service (QoS) What is TrueCircuit? Market Trends and Applications Summary
19 TrueCircuit combines two techniques to guarantee QoS and is patent pending TrueCircuit = IP (Internet Protocol) + TDMA (Time Division Multiplex Access) Data streams are assigned time-slots This offers tremendous benefits: compliant to existing IP standards fixed latency no collision no queuing high bandwidth efficiency Precision synchronization of data streams
20 TrueCircuit generates T-Blocks and time stamps for each T-Block IP Packet (512 bytes) Time Stamp Slot - 4us t T Block - 16ms T-Block - 16ms = 4000 Slots Slot - 4us = IP Packet IP Packet bytes 512 bytes x 8 = 4kb x 4000 = 16Mb (1/16ms) = 1Gb/s
21 TrueCircuit is implemented in Layers 1-3, other QoS standards operate only on Layer 3 COPS Network Layer Datalink Layer Physical Layer DiffServ. MPLS RSVP TrueCircuit TrueCircuit TrueCircuit This offers tremendous benefits: compliant to existing IP standards fixed latency no collision no queuing high bandwidth efficiency
