Network design methodology – Cisco INN Framework –

Filed under: CCDA — antoniopezuela @ 12:34 PM

The Intelligent Information Network (IIN) framework is a vision and architecture that adds intelligence to a network. It’s implemented in phased approach for integrating the network with applications, middleware, servers, and services.

INN’s(Intelligent Information Network)  capabilities:

  • An integrated system – The network is integrated with applications, middleware, and services.
  • Active participation. – Allows the network to manage, monitor and optimize application and services delivery.
  • Police enforcement. – The network enforces policies linking business procesess to network rules.

INN (Intelligent Information Network) has a evolutionary approach that consists of three phases:

  • Integrated Transport involves the convergence of voice, data and video into a single transport network.
  • Integrated Services merges common elements such as storage and data center server capacity.
  • The Integrated Application phase allows the network to become application-aware. The network can optimize application performance.




Network design methodology – Cisco SONA –

Filed under: CCDA — antoniopezuela @ 11:48 AM

SONA(Service-Oriented Network Architecture) is an architectural framework that guides the evolution of enterprise networks to IIN to support new IT strategies.

SONA network are base on a a three layer design:

  • Network Infrastructure. It’s contains the Cisco enterprise architecture (campus, LAN, WAN, datacenter) and facilitates the transport of services across the network.
  • Interactive Service Layer. It’s optimize the communication betwenn applications and services using intelligent network functions such as security, identity, voice, virtualization and quality of service. Services provided at this layer fall into two categories: Infraestructure Services(Identity services, Mobility, Storage, Security, Voice…)  and Application Networking Services.
  • Application Layer. It includes business applications and collaboration applications.


Benefits of SONA:

  • Functionality.
  • Scalability.
  • Availability.
  • Perfomance.
  • Manegeability.
  • Efficiency.
