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

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

Delay Jitter Reliability 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 Predictive Quality

No congestion, all packets get through Requires the use of Over-provisioning

Predictive Quality 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 Low Priority High Priority Top Priority Message Top Priority Data Mgt. Control Mgt. High Priority collected Message Message Message Class-Based Quality

 Node level  Groups data into groups

Pro: •Highly scalable •Easy to implement Con •No standardization •Many different protocols Multicast 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

Why Multicast?

• Used when sending same data to multiple receivers • Better bandwidth utilization • Less host/router processing Multicast Advantages • Enhanced efficiency: Controls network traffic and reduces server and CPU loads • Optimized performance: Eliminates traffic redundancy • Distributed applications: Makes multipoint applications possible IGMP Snooping Concept

 What is Multicast Filtering? • Ensures certain groups receive multicast traffic • Network devices forward multicast traffic to ports that are registered

Unicast: Multicast: Broadcast One to one One to several One to all Multicasting

IGMP is the most popular multicast protocol End devices must support multicast protocol The network infrastructure needs to support IGMP snooping Network Segmentation with Layer 3 OSI Network Model

Layer 3 Network Layer

Routers

Layer 3 Switches

Confidential Difference Between a Layer 3 Switch and Router

Layer 3 Switch Router Routing Performance Extremely Fast Slower Port Density Much Higher Limited Network Routing VLAN Based Interface Based Capability (Exception is EDR-810) Virtual Private Network Not capable Fully capable (VPN) Network Address Not capable Fully capable Translation (NAT) Firewall Not capable Fully capable DHCP Server Limited More capable When is Layer 3 Devices Used? Benefits

 Improved performance in large networks  Increased security  Better control of traffic  Allow for VLAN routing and network segments Ideal Scenario

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

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
