What is application-Aware routing?
Application-aware routing tracks network and path characteristics of the data plane tunnels between Cisco SD-WAN devices and uses the collected information to compute optimal paths for data traffic. These characteristics include packet loss, latency, and jitter, and the load, cost and bandwidth of a link.
What is the purpose of using application-Aware routing in an SD-WAN solution?
Application-aware routing directs traffic based upon an application’s predetermined SLA and user defined applicationprofiles. Traffic is automatically sent to WAN links that have the required network characteristics and path conditions to support these applications in real-time.
What is AAR in Sdwan?
In the context of SD-WAN, AAR is the intelligent forwarding of application traffic across the enterprise WAN ensuring that pre-defined, per-application performance metrics, or service level agreements (SLA), are persistently met at the lowest achievable costs.
In which Cisco SD-WAN software version one can create Slas classes for multicast traffic?
Cisco IOS XE SD-WAN
The Cisco IOS XE SD-WAN devices classify the multicast traffic based on the group address and sets the SLA class.
What is vBond Cisco?
Cisco vBond Orchestrator is a software module that authenticates the Cisco vSmart Controllers and the edge routers in the overlay network and coordinates connectivity between them. It must have a public IP address so that all Cisco vEdge devices in the network can connect to it.
What is Cisco SD-WAN?
Cisco SD-WAN is a cloud-first architecture that separates data and control planes, managed through the Cisco vManage console. You can quickly establish an SD-WAN overlay fabric to connect data centers, branches, campuses, and colocation facilities to improve network speed, security, and efficiency.
What is Cisco vBond?
Cisco vBond Orchestrator—The Cisco vBond Orchestrator automatically orchestrates connectivity between edge routers and Cisco vSmart Controllers. They are either hardware devices or software (Cloud router), that runs as a virtual machine. The edge routers handle the transmission of data traffic.
Which does the SD-WAN architecture require to authenticate an edge device?
The SD-WAN controllers (vBond, vManage and vSmart) and WAN Edge devices need to mutually authenticate and trust each other before establishing the secure control connections. When the SD-WAN controllers authenticate each other and WAN Edge devices, they: Validate the root of trust for the certificate root CA.
How do you create an IP SLA?
To implement IP SLAs network performance measurement, you need to perform these tasks:
- Enable the IP SLAs responder, if required.
- Configure the required IP SLAs operation type.
- Configure any options available for the specified operation type.
- Configure threshold conditions, if required.
What is the purpose of vBond?
vBond – initiates the bring up process of every vEdge device, at the first step it creates secure tunnel with vEdge and informs vSmart and vManage about its parameters like for instance ip address. It has to be fully connected with every device.
How does application aware routing work in Wan?
Application-Aware Routing leverages the calculated network path characteristics values as a measurement and compares with the desired SLA for the application, to dynamically optimize the data path selection for the traffic on the WAN Edge device.
Why do we need application aware routing in Cisco?
The tracking of network and path conditions by application-aware routing in real time can quickly reveal performance issues, and it automatically activates strategies that redirect business critical data traffic to the best available paths that meets the SLA.
How to optimize the path of application traffic?
● In normal network operation, the path taken by application traffic through the network can be optimized by directing it to WAN links that support the required levels of packet loss, latency, and jitter defined in an application’s SLA. ● In the face of network brownouts or soft failures, performance degradation can be minimized.
What is the Cisco SD-WAN design zone guide?
The guide focuses on the step-by-step procedures for defining the network characteristics requirements for an application and leveraging the calculated path liveness and quality measurement to influence the traffic path dynamically, providing the best experience for the applications at all times.
