24 Quality of Service

25 Poll Question Is Quality of Service a metric when you design your network? a) Not really b) Absolutely c) The only metric I use is a ruler

26 What is Quality of Service? Quality of service (QoS) is the overall performance of a of the network, above all the perceived performance seen by the users.

27 Determinism a deterministic system is a system in which no randomness is involved in the development of future states of the system. -Wikipedia

28 Industrial Application Require It Determinism is highly important Many Industrial Protocols like Ethernet/IP require it. Network failure in these environments can be very costly

29 QoS Parameters Delay Jitter Reliability

30 QoS Methodologies Predictive Quality Requires Over-provisioning Flow-Based Quality Flow - A stream of packets or frames with the same quality requirements is a flow IntServ Class-Based Quality Packets are clustered into groups Node based prioritization DiffServ

31 Predictive Quality No congestion, all packets get through Requires the use of Over-provisioning

32 Predictive Quality

33 Why use a QoS protocol? Network applications communicate thru network Different network applications have different network needs - File transfer need large network bandwidth but not real time - VoIP bandwidth is small but need real time & small Jitter QOS prioritize frames to ensure important applications data get process earlier Collected Data Low Priority Control Message Mgt. Message Top Priority High Priority Low Priority Data collected High Priority Mgt. Message Top Priority Control Message

34 Class-Based Quality Node level Groups data into groups Pro: Highly scalable Easy to implement Con No standardization Many different protocols

35 Multicast

36 Poll Question Do you use Ethernet/IP, video, or voice in your network? a) Yes b) Not yet, but plan on it c) Only Ethernet/IP d) No immediate plans

37 Why Multicast? Used when sending same data to multiple receivers Better bandwidth utilization Less host/router processing

38 Multicast Advantages Enhanced efficiency: Controls network traffic and reduces server and CPU loads Optimized performance: Eliminates traffic redundancy Distributed applications: Makes multipoint applications possible

39 IGMP Snooping Concept What is Multicast Filtering? Ensures certain groups receive multicast traffic Network devices forward multicast traffic to ports that are registered B C D E F B C D E F B C D E F A A A Unicast: One to one Multicast: One to several Broadcast One to all

40 Multicasting IGMP is the most popular multicast protocol End devices must support multicast protocol The network infrastructure needs to support IGMP snooping

41 Network Segmentation with Layer 3

42 OSI Network Model Layer 3

43 Network Layer Routers Layer 3 Switches Confidential

44 Difference Between a Layer 3 Switch and Router Layer 3 Switch Router Routing Performance Extremely Fast Slower Port Density Much Higher Limited Network Routing Capability Virtual Private Network (VPN) Network Address Translation (NAT) VLAN Based Not capable Not capable Interface Based (Exception is EDR-810) Fully capable Fully capable Firewall Not capable Fully capable DHCP Server Limited More capable

45 When is Layer 3 Devices Used?

46 Benefits Improved performance in large networks Increased security Better control of traffic Allow for VLAN routing and network segments

47 Ideal Scenario Large installations Need for segregation or/and isolation Need for security NAT is needed Interfacing with WAN

48 Broadcast In the Layer 2 Network Hub/Switch Hub/Switch Server Server Broadcast Domain Hub/Switch Hub/Switch Server There are 15 devices If everyone send a broadcast everyone will receive 14 packets

49 Larger Broadcast Domain Hub/Switch Hub/Switch Hub/Switch Server If everyone send 100 broadcast Server packets Server If there are 1000 devices everyone will receive packets Networking will becomes very busy Hub/Switch

50 Divide Broadcast Domain Broadcast Domain A Router/Layer 3 Switch Broadcast Domain B Router/Layer 3 Switch Broadcast Domain C Broadcast

51 Key Takeaways Industrial networks are moving towards Converged networks that require a lot of bandwidth Setting up Quality of Service Scheme in a Network is crucial Multicast is important in environments where there is a lot of consumers of a producer Layer 3 is important in large networks to improve network performance and security
