Application Scenarios for Path/Connectivity Detection

Application Scenarios for Path/Connectivity Detection

IPv4 Path Detection

Using Path Detection on VXLAN

  • Path detection between two VMs in the same subnet

    In Figure 13-8, different services are run on the data center network of a company, and the human resource department is allocated to VM1 and VM2. VM1 and VM2 can communicate with each other. The O&M personnel want to view the entire path from VM1 to VM2.

    Figure 13-8 Using path detection in the same VXLAN subnet

    In Figure 13-8, the Spines are the VXLAN Layer 3 gateways, the Switches perform transparent transmission on the VXLAN, and the Leaves are the VXLAN Layer 2 gateways. All Spines, Switches, and Leaves need to set up OpenFlow and NETCONF connections with the Agile Controller. The Agile Controller delivers the configuration related to path detection to the Spines, Switches, and Leaves through NETCONF. The Agile Controller sends path detection packets using the OpenFlow Packet-out messages, and the switches send detection information using the OpenFlow Packet-in messages.

  • Path detection between two VMs on different subnets

    In Figure 13-9, different services are run on the data center network of a company, the human resource department is allocated to VM1 and VM2, and the engineering department is allocated to VM3 and VM4. The two departments can communicate with each other. The O&M personnel want to view the entire path from VM1 to VM3.

    Figure 13-9 Using path detection between different VXLAN subnets

    In Figure 13-9, the Spines are the VXLAN Layer 3 gateways, the Switches perform transparent transmission on the VXLAN, and the Leaves are the VXLAN Layer 2 gateways. All Spines, Switches, and Leaves need to set up OpenFlow and NETCONF connections with the Agile Controller. The Agile Controller delivers the configuration related to path detection to the Spines, Switches, and Leaves through NETCONF. The Agile Controller sends path detection packets using the OpenFlow Packet-out messages, and the switches send detection information using the OpenFlow Packet-in messages.

Using Path Detection on VXLAN + Traditional Network

In Figure 13-10, the data center network of a company includes two physical areas, POD1 and POD2. The human resource department is in POD1 and the engineering department is in POD2. The two departments can communicate with each other. The O&M personnel want to view the entire path from VM1 to VM3.

Figure 13-10 Using IP path detection on VXLAN + traditional network

In Figure 13-10, the LSWs are traditional Layer 3 switches of IP network, the Spines are VXLAN Layer 3 gateways, the Switches perform transparent transmission on the VXLAN, and the Leaves are the VXLAN Layer 2 gateways. All LSWs, Spines, Switches, and Leaves need to set up OpenFlow and NETCONF connections with the Agile Controller. The Agile Controller delivers the configuration related to path detection to the LSWs, Spines, Switches, and Leaves through NETCONF. The Agile Controller sends path detection packets using OpenFlow Packet-out messages, and the switches send detection packets using OpenFlow Packet-in messages.

DSCP-based IPv6 Path Detection

In Figure 13-11, the data center network of a company is the IPv6 over IPv4 VXLAN network, that is, the overlay network is an IPv6 network and the underlay network is an IPv4 network. Different services are deployed on the data center. The human resource department is deployed in VM1 and the engineering department is deployed in VM2. VM1 accesses the VXLAN through VTEP1, and VM2 accesses the VXLAN through VTEP2. The O&M personnel want to view the entire path between VM1 and VM2.

Figure 13-11 IPv6 over IPv4 VXLAN path detection

In Figure 13-11, the Agile Controller has set up OpenFlow and NETCONF connections with the spine and leaf switches, and delivers path detection configurations to the spine and leaf switches through NETCONF. The Agile Controller sends path detection packets using OpenFlow Packet-out messages, and the switches send detection packets using OpenFlow Packet-in messages.

IPv6 VXLAN Path Detection

In Figure 13-12, different services are run on the data center network of a company. The human resource department is allocated to VM1 and the engineering department is allocated to VM2. VM1 accesses the VXLAN through VTEP1, and VM2 through VTEP2. The O&M personnel want to view the entire path from VTEP1 to VTEP2.

Figure 13-12 IPv6 VXLAN path detection application diagram

In Figure 13-12, the Agile Controller has set up OpenFlow connections with the spine and leaf switches, and IPv6 VXLAN path detection has been enabled on the switches. The Agile Controller sends path detection packets using OpenFlow Packet-out messages, and the switches send detection packets using OpenFlow Packet-in messages.

Connectivity Detection

In Figure 13-13, different services are run on the data center network of a company. The human resource department is allocated to VM1 and the engineering department is allocated to VM2. VM1 and VM2 are on different subnets. The O&M personnel want to know the connectivity and packet loss rate between VM1 and VM2.

Figure 13-13 Connectivity detection diagram

In Figure 13-13, the Agile Controller and Leaf1 set up OpenFlow and NETCONF connections, and the Agile Controller delivers connectivity configuration to Leaf1 through the NETCONF connection. The source and destination IP addresses are used as detection flags. The Agile Controller sends an OpenFlow Packet-out message carrying the ICMPv4 Echo Request packet to the switch. After receiving the ICMPv4 Echo Reply packet matching the ICMPv4 Echo Request packet, the switch sends an OpenFlow Packet-in message carrying the ICMPv4 Echo Reply packet to the Agile Controller.
