TIME Journey to the SPACE

  1. 1. 1 Time Journey to the SPACE James Chin Sze Yih, Principle Engineer james.chin@time.com.my The Road to Virtualization: our deployment experience, technical implications and impact on operations MYNOG 2019
  2. 2. Index • Background/Drivers for SDN/NFV Deployment • Key Enablers • Use Cases • SDN/NFV Deployment Challenges • Essential Skills for Next Generation Network Engineers July 2, 2019 MYNOG 2019 2
  3. 3. 3 Flexibility • High cost and complexity for new service • Elastic Capacity • New Business Models • Faster Time to Market for New Services • Slow service rollout and scaling • On-demand Service • Doing more with less • Reduce OpEx: Operational Efficiency • Reduce CapEx: Costs Rise Faster than ARPU SPEED COSTFlexibility Business Challenges in current Service Provider Environment July 2, 2019 MYNOG 2019
  4. 4. Business Challenges in current Service Provider Environment 4 FlexibilitySPEED COSTFlexibility Automation Virtualization July 2, 2019 MYNOG 2019
  5. 5. The materials to create Rocket July 2, 2019 5 SDN approach to network management that enables dynamic, programmatically efficient network configuration in order to improve network performance and monitoring making it more like cloud computing than traditional network management. ETSI An independent standardization organization, that has been instrumental in developing standards for ICT within Europe. The WG develops NFV standards and proofs- of-concept. NFV A network architecture concept that uses the technologies of IT Virtualization to virtualize entire classes of network node functions OPEN STACK A Cloud computing platform for public/private clouds that abstracts data centers intopools of resources MYNOG 2019
  6. 6. OpenStack Overview • Cloud computing platform for Public/Private Cloud • Abstract data centers into pool of resources • Provides management layer for efficient, automated allocation of resource • Empower operators, admins, users via self service portal • Provides API to develop cloud-aware application Image Source: www.openstack.org API July 2, 2019 MYNOG 2019 6
  7. 7. Network Function Virtualization Overview Network Function Capacity (Hardware) Decoupling Server x86 Hypervisor VM OS Router VM OS Switch VM OS Load Balancer VM OS Firewall VM OS Media Server Approach July 2, 2019 MYNOG 2019 7
  8. 8. VNF Deployment Options July 2, 2019 8 Bare Metal • Dedicated Hardware • High Performance • Easy to secure • No Virtualization overhead Virtual Machine • Shared host for multiple VNF • Performance limited by virtualization • No shared kernel-> More secure Containers • Shared host for multiple VNF • Bare metal performance • Share kernel with host -> less secure Image Source: Cisco MYNOG 2019
  9. 9. NFV or VNF or Service Chain • Network Function Virtualization • Refers to the idea of replacing dedicated network appliances (such as routers and firewalls) with software running on standard servers. • Typically includes a Hypervisor and the software runs as a Virtual Machine • Virtual Network Function • One or more Virtual Machines performing a single network function • Service Chain • Collection of 1 or more VNFs providing a network service July 2, 2019 MYNOG 2019 9
  10. 10. Network Function Virtualization framework (ETSI NFV Architectural) July 2, 2019 MYNOG 2019 10
  11. 11. Network Function Virtualization framework (NFV MANO) • Three functional blocks • Virtualized Infrastructure Manager (VIM) • VNF Manager (VNFM) • NFV Orchestrator (NFVO) • Main function • The “brain” of NFV architecture • End-to-end service and NFV network mapping • Managing the life cycle of VNFs • Create VNF • Scale VNF (increase or reduce the capacity of the VNF) • Terminate VNF • Interfacing with OSS systems July 2, 2019 MYNOG 2019 11
  12. 12. What is SDN ? Many different thing to many different people July 2, 2019 MYNOG 2019 12
  13. 13. SDN - The Programmable Network Overview Source: www.opennetworking.org Southbound API Northbound API (Network abstraction) E.g. RESTAPI,JSON,XML Centrally managed: Network intelligence is (logically) centralized in software-based SDN controllers that maintain a global view of the network, which appears to applications and policy engines as a single, logical switch. Southbound API (Vendor-neutral)E.g. Openflow,SNMP,NETCONF,etc… July 2, 2019 MYNOG 2019 13 Northbound API
