  1. 1. Circuit Services - IPTV Christian Todorov Internet2 Fall Member Meeting October 9, 2007
  2. 2. Internet 2 , Circuits & You <ul><li>Where we have been </li></ul><ul><li>Changing needs </li></ul><ul><li>Why circuits are different </li></ul><ul><li>How Internet 2 provides circuits </li></ul><ul><li>Internet 2 Circuit offerings </li></ul><ul><li>Who to contact </li></ul>
  3. 3. Abilene Network <ul><li>Internet 2 ’s previous network (Abilene) was IP only and based on unprotected 10G (OC-192) waves on the Qwest infrastructure </li></ul><ul><li>Utilized IS-IS </li></ul><ul><li>Natively supported IPv4/v6 and multicast </li></ul><ul><li>IP is great… for most people… most of the time… </li></ul>
  4. 4. Changing Needs <ul><li>As the capabilities available to the research community changed, the demands on the network also changed </li></ul><ul><li>e-science applications and facilities grew and exerted greater performance pressures on the network where TCP and shared environments were no longer acceptable </li></ul><ul><li>Dedicated infrastructure was becoming a requirement </li></ul>
  5. 5. The New Requirements <ul><li>High performance applications are dependent on high performance networks </li></ul><ul><li>Networks must be fast, reliable, scalable, have flexible architectures, be cost effective, capable of delivering multiple services across multiple network layers, easy to operate and maintain, and have a view towards the future </li></ul><ul><li>Enable the user – the network as a service </li></ul>
  6. 6. Circuits: Why They are Different <ul><li>IP networks switch packets of information across shared networks to multiple locations and operate at Layer 3 </li></ul><ul><ul><li>Shared packet networks are well suited to applications where data transfers are intermittent, multi-point, or have smaller file size transfer requirements </li></ul></ul><ul><ul><li>A “best-effort” service </li></ul></ul><ul><ul><li>Represents the largest number of uses of the current network </li></ul></ul><ul><li>Circuits connect two discreet endpoints with dedicated connections and operate at Layer 2 or below </li></ul><ul><ul><li>Circuit based networks are well suited to long duration, point to point connections that support large data transfers or transfers that require very predictable network performance </li></ul></ul><ul><ul><li>Is a dedicate resource </li></ul></ul><ul><ul><li>Connection oriented service </li></ul></ul><ul><ul><li>Represents a small number users who have high demands of the network: bandwidth, performance, desire to run alternative protocols </li></ul></ul>
  7. 7. Wavelength & Circuit Services <ul><li>Connection oriented services provide for: </li></ul><ul><ul><li>Guaranteed bandwidth and predictable jitter and latency (repeatable, dependable performance between collaborating sites) </li></ul></ul><ul><ul><li>Traffic segregation (support specific policy or traffic engineering requirements) </li></ul></ul><ul><ul><li>Router bypass: Express links created for high-bandwidth, limited duration long-haul traffic reducing the need for mid-path L3 interfaces </li></ul></ul><ul><ul><ul><li>Cost efficiency: L3 router blades cost > L2 ports > L1 or L0 interfaces </li></ul></ul></ul><ul><ul><ul><li>Capability tradeoff but could possibly improve performance </li></ul></ul></ul>
  8. 8. Internet2 Circuit Services <ul><li>Internet2 offers two types of Circuits </li></ul><ul><ul><li>Static circuits </li></ul></ul><ul><ul><ul><li>Exist on the Circuit Infrastructure supported by both the Infinera and Ciena devices </li></ul></ul></ul><ul><ul><ul><li>Manually provisioned by the NOC </li></ul></ul></ul><ul><ul><ul><li>50Mbps to 10Gbps </li></ul></ul></ul><ul><ul><ul><li>Fee for service </li></ul></ul></ul><ul><ul><ul><li>Longer duration: months to years </li></ul></ul></ul><ul><ul><ul><li>Can have dedicated protection </li></ul></ul></ul><ul><ul><ul><li>A contracted, assured service </li></ul></ul></ul><ul><ul><li>Dynamic Circuits </li></ul></ul><ul><ul><ul><li>Exist within the Dynamic Circuit Network (DCN) supported by the Ciena CoreDirectors </li></ul></ul></ul><ul><ul><ul><li>Provisioned automatically </li></ul></ul></ul><ul><ul><ul><li>Requires participation in the DCN protocols </li></ul></ul></ul><ul><ul><ul><li>50Mbps to 10Gbps </li></ul></ul></ul><ul><ul><ul><li>Have no fee for use </li></ul></ul></ul><ul><ul><ul><li>Short duration ~2 weeks </li></ul></ul></ul><ul><ul><ul><li>Best effort service </li></ul></ul></ul>
  9. 9. Connecting to the Internet2 Circuit Infrastructure <ul><li>Accessing the Circuit Infrastructure </li></ul><ul><ul><li>One must have a connection to the Internet2 circuit infrastructure in order to access the Internet2 circuit services. </li></ul></ul><ul><ul><li>The circuit connection is separate from the IP connection </li></ul></ul><ul><ul><li>The standard connection to the circuit infrastructure is either 1GE or 10GE – other interface types are supported at an additional fee </li></ul></ul><ul><ul><li>ONE physical connection to the circuit infrastructure on the Ciena CoreDirectors will support BOTH the static circuit service AND the Dynamic Circuit Network </li></ul></ul><ul><ul><li>For the first year, the connection to the Cienas are available to IP connectors at no additional fee for a standard connection (1GE or 10GE) that is equal in bandwidth to the contracted IP connection, e.g. 10G IP connectors receive the use of a 10G circuit connection. (Non-connectors may be subject to additional port fees) </li></ul></ul><ul><ul><li>Circuit connections are available to Connectors, members and peers </li></ul></ul>
  10. 10. Network Design
  11. 11. <ul><li>Example of Optical only Node for connected RON or Peer Network </li></ul>Internet 2 Network Node Architecture
  12. 12. <ul><li>Infinera DWDM Gear - Static at the start </li></ul><ul><li>Grooming capabilities in ADM to provide sub channels and HOPI types of activities at the start </li></ul><ul><li>Simplified and standardized interface to connectors, exchange points, and other global research and education networks - 2 x 10 Gbps interfaces </li></ul><ul><li>Measurement and control servers will support the node </li></ul>Internet 2 Network Node Architecture
  13. 13. Dynamic Circuit Network <ul><li>The Dynamic Circuit Network (DCN) is considered a network due to its characteristics and behavior: it is protocol driven, has the capability to determine paths, can exchange network information with neighbors and it is aware of its own resources </li></ul><ul><li>The DCN concept expands the notion of networking where a network facility is able to provide the most appropriate resource for a given demand </li></ul><ul><li>Dynamic Circuit Network (DCN) is developmental until 1-1-08 and persistent thereafter </li></ul><ul><li>Invitations are currently being sent out by Internet2 to the connectors for participation in DCN </li></ul><ul><li>A DCN connection does not imply a connection to the IP network </li></ul><ul><li>DCN participation is critical to its success as its value grows with the number of participants </li></ul>
