SDN Software Defined Network
separated in 4 layers
motto: separate what we can & concentrate what we can.
SDN strategy that addresses the key challenges customers face with 4 steps approach:
1. centralized management
2. extract services
3. centralized controller
4. optimize the hardware
Step 1: Centralize Management:
Centralize network management, analytic and configuration functionality - a single master that configures all networking devices.
This lowers operating cost and allows customers to gain business insight from their networks.
Step 2: Extract Services:
Extract (networking and security) services from the underlying hardware.
This enables network and security services to independently scale using industry-standard x86 hardware based on the needs of the solution. This next generation of programmable networks will be introduced with the JunosV App Engine.
Step 3: Centralized controller:
The brain of SDN that enables multiple network and security services to connect in series across devices within the network.
"SDN Service Chaining" -- using software to virtually insert services into the flow of network traffic. Service chaining functionality is crudely accomplished in today's physical world using separate network and security devices. With SDN Service Chaining, networks can dynamically respond to the needs of the business. This step will dramatically reduce the time, cost and risk for customers to design, test and deliver new network and security services. Juniper Networks anticipates delivering SDN Service Chaining functionality in 2014 utilizing the SDN controller technology acquired from Contrail Systems, together with the evolution of the JunosV App Engine.
Step 4: Optimize the HW:
Allow the usage of network and security hardware to deliver high performance.
The combination of optimized hardware together with SDN Service Chaining allows customers to build the best possible networks.
6 principles:
1. Cleanly separate networking software into four layers (or planes) -- management, services, control and forwarding.
2. Centralize the appropriate aspects of the management, services and control software to simplify network design and lower operating costs.
3. Use the cloud for elastic scale and flexible deployment, enabling usage-based pricing to reduce time-to-service and correlate cost based on value.
4. Create a platform for network applications, services and integration into management systems, enabling new business solutions.
5. Standardize protocols for interoperable, heterogeneous support across vendors, providing choice and lowering cost.
6. Broadly apply SDN principles to all networking and network services including security from the data center and enterprise campus to the mobile and wireline networks used by service providers.
traditional network challenge:
multiple copies of config
cant easily scale
time consuming & prone to error
maintain true network config
Benefit of SDN:
centralized config
extensive automaticion - scale with ease
point&click
centralized manager of true network config
data center:
server is virtualized
storage is virtualized
network is not yet virtualized
