Junos Space Management Applications:
Rapid Device Discovery
The Junos Space Network Management Platform uses a variety of methods to discover network devices and bring them under management. Once the devices are under management, the Junos Space platform collects the entire physical inventory of these network elements and maintains a centralized repository of real-time information about each device, such as:
- List of line cards (FPC)
- Interface cards (PIC)
- Serial number for each chassis component
- Juniper Networks Junos OS version
- Operational, administrative state, speed/duplex of the interfaces
- Chassis type
Once devices have been discovered, pre-staging takes the devices already under Junos Space management and prepares them for service activation. Connectivity Services Director automatically detects the MPLS roles and the corresponding UNIs of discovered devices. The pre-staging process discovers network provider edge (N-PE) devices in the Junos Space database and assigns roles to those devices and their interfaces. This simplifies the service provisioning task, because only qualified devices are allowed to be selected for services.
Automated MPLS Resource Management
Deploying Carrier Ethernet services requires multiple network resources to be allocated and tracked per customer site. The most common network resources are VLAN ID, Virtual Circuit (VC) ID, route targets, and route distinguishers. In the case of VLAN IDs, these are usually allocated per customer-facing interface. When a service provider is potentially handling hundreds of customers, each being provisioned hundreds of services, tracking network resources can quickly become unmanageable and unscalable—particularly when the resources are tracked manually. For example, consider a scenario where a customer is experiencing loss of packets from one site to another. How quickly can a help desk operator troubleshoot the problem to help this customer?
Connectivity Services Director provides automated MPLS resource management. It auto allocates VLAN IDs to the UNIs, VC IDs and IPV4 addresses, and it tracks used resources. This not only minimizes user input during provisioning but also guarantees that the service provisioning pushed to the devices does not conflict with existing resources on the network.
Rapid Service Design
Predefined service definitions in Connectivity Services Director capture Juniper best practices for standard services in terms of the options selected, prefilled values for attributes such as bandwidth and more. Privileged users can create custom service definitions for non-standard network configurations.
Predefined Service Definitions
Juniper-recommended configurations for various service types include the following:
- P2P E-LINE service
- Full mesh and hub-and-spoke VPLS service
- Full mesh and hub-and-spoke L3VPN service
Automated Service Provisioning
Seventy-five percent of network outages are due to human error, such as misconfiguration when changing an existing customer configuration. Imagine that you have to activate a 20-site virtual private LAN service (VPLS) for a customer. How do you get started? Start a spreadsheet and keep track of the endpoints, PE routers, interfaces, VLANs per interfaces, route targets, route distinguishers, and other MPLS resources? You start by configuring the first site with great attention to detail, update your spreadsheet or piece of paper, and slowly make your way to the twentieth site by the end of the week. Now, how do you know that the VPLS for the twentieth site is working? You need to go site by site and verify that you have reachability to all remote sites, issuing 20x19 pings.
What happens when you lose the spreadsheet that contains all of the information for this customer VPN? What do you do if you need to add a twenty-first site to this VPN and verify that this new site is working with the 20 preceding sites?
Connectivity Services Director provides a simple GUI-based provisioning tool that allows the operator to easily select the endpoints for activating a customer’s multisite VPN. It also provides pre-validation before applying a VPN configuration to target devices, verifying that there are no collisions with existing configurations on the target devices and ensuring that set of network parameters ultimately works and renders the VPN connection functional.
Connectivity Services Director also facilitates bulk provisioning of pseudowires for mobile backhaul deployments. This capability greatly simplifies provisioning of thousands of cell sites simultaneously with a configuration that is somewhat similar. Connectivity Services Director helps to design, provision, and activate RSVP signaled label-switched paths (LSPs), as well as static LSPs. These LSPs can be configured as P2P, P2MP or full mesh LSPs.
Automated MPLS Service Validation and Troubleshooting
Generating an accurate configuration and applying that configuration is the first step. But ensuring that the service is operational is an additional step that Connectivity Services Director provides. Verifying that the control plane and data plane are functional guarantees the VPN service is actually up and running.
The real value of Junos Space Connectivity Services Director comes when the number of VPN sites is large. The application detects all of the sites in a VPN and is able to verify that the label-switched paths (LSPs) are operational on all sites—issuing a full-mesh MPLS Operation, Administration, and Maintenance (OAM) verification to validate that the data plane is operational.
If one or more sites are not reachable, the operator is immediately alerted to the broken sites with a detailed analysis of the failure conditions.
Connectivity Services Director—with its built-in auto-discovery (AD), resource management capabilities and service design— allows service providers to quickly start offering Carrier Ethernet services in a very cost-effective manner.
Connectivity Services Director provides the following benefits:
- Removal of all possible manual configuration errors
- One centralized location for all L2VPN and L3VPN services
- Reduced mean time to recovery (MTTR) when troubleshooting customer connectivity issues
Junos Space Connectivity Services Director includes an optional component that manages synchronization devices such as Juniper’s TCA Series Timing Appliances as well as synchronization subsystems within other Juniper devices that support the IEEE 1588-2008 standard—commonly known as Precision Time Protocol, or PTP. In addition to managing device level synchronization attributes, Connectivity Services Director also manages logical timing entities or domains that comprise groups of devices or subsystems. Users can create timing domains, assign various synchronization devices and subsystems to a domain and then apply a specific timing service template to each domain. Connectivity Services Director scans through the devices in the timing domain and performs configuration operations one-by-one based on the service template, thus automating and greatly simplifying the configuration process. Connectivity Services Director provides configuration management, health monitoring and discovery of synchronization devices.
Service Validation and SLA Monitoring
After a service has been provisioned, the service provider must be able to monitor the service in order to guarantee SLAs. Monitoring involves checking end-to-end path connectivity of the control plane and data plane. Control plane validation involves verifying that the MPLS edge routers have indeed established logical connections. For E-LINE LDP and BGP, LSPs have to be peered, and pseudowires from both PE routers have to be operationally in “up” status. For VPLS multipoint-to-multipoint, each site/leg has to have all the configured LSPs operationally “up.”
SLA Iterator profile
Data plane validation is one last step that leverages exiting MPLS OAM pings to ensure that the data plane is indeed working. The Connectivity Services Director application provides the following monitoring capabilities:
- Connectivity Fault Management (CFM) configuration at the port and interface level
- Service level CFM for P2P (E-Line) and VPLS (E-LAN) services
- Support for Y.1731 based one-way and two-way measurements for frame delay, frame delay variation, frame loss and service availability
Connectivity Services Director enables users to set up CFM flows between service endpoints in order to monitor the endto-end service using Y.1731 frames. Users can choose to gather performance data on demand, or create SLA Iterators and assign them to a service in order to periodically measure the data. In addition to these iterators, users can also associate an Action Profile with a service to describe actions that must be performed when connectivity problems are detected with the service.
