IBM Software Defined Networking The Brave New World of IT
© 2014 IBM Corporation
The velocity of developing new applications and new business models is driving the adoption of auto provisioned software defined environments.
§ Developing or planning to develop mobility applications for customer or employee services
§ Developing or planning to develop big data and/or analytics applications
§ Leveraging cloud models to lower the cost of entering new markets
§ Implementing or planning to implement a DevOps model
2
§ Concerned vulnerability within a security zone (server to server exploitation)
§ Hampered by the time it takes to provision network segmentation and services

The shift to software defined networks has the potential to transform the way networks are designed and delivered.
Software-based paradigm with well-defined programming interfaces and abstractions
§ Provides a unified way to support network services and integration
§ Improves development and delivery efficiency in cloud and network services through the use of open and standard APIs
§ Supports Service Provider and Cloud business models that demand a more flexible, agile IT infrastructure and is common for all clients served
§ Facilitates faster delivery of new features through software updates not bound to hardware specific features

IBM will adopt SDN technologies to improve agility, responsiveness, and client satisfaction through integration and automation with overall software defined environment orchestration.
Approach § Adopt overlay networks regardless of
physical network infrastructure § Adopt network function virtualization
starting with firewalls and load balancers
§ Integrate provisioning and management with overall infrastructure management through software defined environments (SDE)
§ Use open, standards-based technologies where feasible
§ Ensure current high standards for availability and performance are met or exceeded in support of mission critical systems
Benefits
§ Accelerate value and increase agility of network services (i.e. firewalls)
§ Automate through programmable APIs
§ Enable flexibility in hosting options via software based network services
§ KPIs: – 10x faster provision of network
services (24 hours vs. 4 weeks)
– Improved TTV allows GTS to recognize revenue sooner

If properly developed and implemented SDN technology can help address key challenges in the delivery of IT services.
ü Increase flexibility and reduce complexity of application deployment
ü Improve flexibility of workload placement
ü Support increase in East-West traffic orientation
ü Enable improved regulation compliance that require segregation of application flows
ü Enable improved support for multi-tenant data centers
ü Improve application of change management
ü Maintain or improve scalability of infrastructure
ü Maintain or improve high availability
ü Maintain or improve required feature sets

Implementation of an NSX environment requires considering the traditional aspects of network design along with new ways to reduce cost while improving agility and stability.
§ Layer 2/3 design within NSX environment (distributed logical switch, distributed logical Routers, sub net segmentation versus micro segmentation)
§ Edge Services Gateway • Capacity, performance, availability • Placement – services rack versus inside server farm • Routing - OSPF, BGP, or static routes between legacy network
and Edge Services Gateway
§ East/West to legacy and bare metal • Through Edge Services Gateway (L3) or bridging (L2)
§ North/South (newly defined) § Physical network – rethinking the data center
• Layer 3 to the physical access switch or layer 2 • Connecting the server physical nodes - LACP, Source IP or
Originating Port hash (not LBT) • Virtual (software) versus hardware based appliances

This new technology has significant implications to existing security models as well, tools, organization, and skills used to design and manage the network.
§ Security • Use of micro segmentation • Re-thinking policy, rules and defaults • New opportunities – exploiting meta data • Subnet design
§ Network Management • Tools – VC Ops - • Topology – understanding both physical and virtual • Deep diagnostics – ESXi capture capabilities, VXLAN decode • Availability, Event, Performance, Capacity management
§ Organization and Skills • Server, network and security working closer together

Identifying a project with a limited scope and risk is a good way to get started.
§ Identify requirements
§ Prioritize and scope a project
§ Conduct readiness assessment
§ Develop adoption plans • PoC • Design • Pilot • Deployment
