Traffic Conditions in a Converged Network
§

Modern networks must support various types oftraffic:
• • • • • •

Voice and video traffic Voice applications traffic Mission-critical traffic Transactional traffic Network management traffic Routing protocol traffic

§

§

This mix of traffic greatly impacts the network requirements such as security and performance. To help enterprises, Cisco has developed the Intelligent Information Network (IIN).

Cisco Intelligent Information Network
§

The Intelligent Information Network (IIN):
• •



Integrates networked resources and information assets. Extends intelligence across multiple products and infrastructure layers. Actively participates in the delivery of services and applications.

§

The IIN technology vision consists of 3three phases in which functionality can be added to the infrastructure as required:
• • •

Integrated transport Integrated services Integrated applications

3 Phases of the IIN
§

Phase 1: Integrated transport


Integrates data, voice, and video transport into a single, standards-based, modular networksimplifying network management and generating enterprisewide efficiencies. Integrated services help to unify common elements, such as storage and data center server capacity. IT resources can now be pooled and shared, or virtualized, to address the changing needs of the organization. Business continuity is also enhanced in the event of a local systems failure because shared resources across theIIN can provide needed services. This phase focuses on making the network application-aware so that it can optimize application performance and more efficiently deliver networked applications to users.

Cisco SONAFramework
§

The Cisco Service-Oriented Network Architecture (SONA) is an architectural framework to create a dynamic, flexible architecture and provide operational efficiency through standardization and virtualization.




SONA provides guidance, best practices, and blueprints for connecting network services and applications to enable business solutions. In this framework, the network isthe common element that connects and enables all components of the IT infrastructure.
