2. BPS Customer Presentation 06-02 - 1 Industry Analysis “…the total amount of bandwidth required is increasing (i.e., 20%-40% annually).” “…total network budgets continue to increase. We expect network costs to grow from 25% of the IT budget in 2000 to 32% in 2005. These pressures will force IT planners to increase the use of various quality-of-service (QoS) mechanisms (e.g., queuing, TCP rate control) through 2005.” “As the downturn fades, organizations will feel an increasing need to boost their productivity by adding new applications, putting pressure on bandwidth and requiring more intelligent switches.” Cost Savings Across the Network Life Cycle, 9/7/01, Meta Group Updated Worldwide LAN Switch Market Forecast and Analysis, 2001- 2006, 12/1/01, IDC (International Data Corp.)

3. BPS Customer Presentation 06-02 - 2 The ability of the network to provide better or “special” service to users/devices and applications Quality of Service is... Consistent, Reliable, Predictable Performance VoiceVideoData

4. BPS Customer Presentation 06-02 - 3 Quality of Service or Class of Service? Can’t be exclusive of one another “Quality of Service” has a broad definition –It is a measurement of how well a network behaves –It includes categorizing a particular connection or flow “Class of Service” has a more granular definition –It implies the categorization of services into distinct classes that can be treated individually, relative to each other The interpretation of either term can depend on the priorities of the service provider, network manager, or the end user –Predictable network characteristics or preferential traffic treatment?

5. BPS Customer Presentation 06-02 - 4 Levels of Quality of Service Guaranteed Services –Provides circuit-switch-like services –Reserves or guarantees necessary bandwidth Tiered Services –Provides traffic prioritization by separating traffic by criticality –Treat important traffic better; less important traffic worse –High probability traffic will get through but with no “guarantees” Best Effort –“What you see is what you get” –Needs bandwidth

6. BPS Customer Presentation 06-02 - 5 Why Should a Network Have QoS? Critical business transactions and applications run over the network infrastructure Deploy converged voice, video and data applications in a reliable and cost effective manner Bandwidth is not an unlimited or inexpensive resource There will always be places in your network where there is congestion Over-engineering is costly and over-subscription inevitably leads to poor network performance Ensure network availability for mission critical applications, devices, and users Optimize network resources and reduce overall IT costs

28. Business Policy Switch Quality of Service

29. BPS Customer Presentation 06-02 - 28 IP Quality of Service (QoS) QoS provides the ability to read, alter, prioritize and tag or mark IP traffic based upon information imbedded in Type of Service (ToS) field in the IP header as established by the IETF committee DiffServ is based upon Type of Service (ToS) field Employs a DSCP-to-802.1p mapping table via hardware based ASICs DiffServ used over IntServ due to superior scaling capabilities The ability to prioritize traffic allows for: –Better voice quality when using IP telephony –Better quality streaming videos and video conferencing –The ability to offer levels of service based upon bandwidth allocation Video Server DesktopI2004 IP PhoneFTP Server

30. BPS Customer Presentation 06-02 - 29 Differentiated Services (DiffServ) How it works ….. DiffServ provides QoS by simplifying resource reservations to a small number of service classes provisioned throughout the network. Consistent per hop behavior (PHB) for aggregate flow classes is defined in the core of the network –Pre-defines QoS service level for all traffic in the aggregate flow –Bandwidth Requirements –Delay sensitivity –4 Standards – Expedited Forwarding, Assured Forwarding, Discard Eligible, Class Selector Traffic at the edge is classified according QoS service levels – marking DSCP to match service class Micro-Flows Premium Service, Expedited Forwarding Silver Service, Assured Forwarding Becomes member of aggregate flow class that is recognized by common DSCP
