Solution Architecture and Test Objectives

Solution Goals

The solution goals and deliverables include:

• Validate solutions through incremental testing efforts/test profiles.
• Identify and close solution gaps to ensure completeness.
• Build and deliver full test reports and design recommendations for network engineers implementing this solution.
• Provide configuration details, design, and implementation guidance for validated use cases.

The JVD solutions delivered as part of an existing Metro JVD track are:

• Metro Ethernet Business Services—Juniper Validated Design (JVD): Leveraging metro fabric design concepts to support wholesale service delivery mechanisms.
• 5G xHaul CSR Seamless Segment Routing—Juniper Validated Design (JVD): Using fronthaul access and aggregation principles.
• 5G Fronthaul Class of Service—Juniper Validated Design (JVD) : Class of Service modelling for access and aggregation architectures.

Solution Non-Goals

The solution non-goals are:

• BBE/BNG:
  • Topology discovery
  • CPE IPv6 timer support, i.e., aggressive DHCP timers and/or IPv6 state when BBE/BNG fails over.
  • Scaling higher than 4x AN to 1x BBE/BNG.
  • BBE/BNG subscriber scaling per MX product.
  • In respect to the functional architecture, for Broadband Forum TR-101 we have assumed that the compliant xDSL and xPON Access Nodes have the ability to implement N:1 service VLANs or 1:1 per subscriber VLANs for the unicast services, and IGMP/MLDP snooping for multicast services like IPTV.
  • H-Policer QoS model
• Access Nodes
  • xDSL
  • xPON
  • IGMP/MLDP
• Timing and synchronization
• Network optimisation, i.e. BFD, BGP timers
• Network Slicing/Flex-Algo/BGP-CT/SRv6 for underlay configuration
• SLA monitoring: RFC 2544, Y.1564, TWAMP, Paragon Active Assurance
• Telemetry
• LDP and/or RSVP signalling for MPLS
• Class-of-Service (CoS) in the port mode
