Cisco SONA Offering

The SONA framework defines the following three layers:

1. Networked Infrastructure layer: Where all the IT resources are interconnected across a converged network foundation. The IT resources include servers, storage, and clients. The Networked Infrastructure layer represents how these resources exist in different places in the network, including the campus, branch, data center, enterprise edge, WAN, metropolitan-area network (MAN), and with the teleworker. The objective of this layer is to provide connectivity, anywhere and anytime. The Networked Infrastructure layer includes the network devices and links to connect servers, storage, and clients in different places in the network.

2. Interactive Services layer: Includes both application networking services and infrastructure services. This layer enables efficient allocation of resources to applications and business processes delivered through the networked infrastructure. This layer includes the following services:
   --Voice and collaboration service
   -- Mobility services
   -- Wireless services
   -- Security and identity services
   -- Storage services
   -- Compute services
   -- Application networking services (content networking services)
   -- Network infrastructure virtualization
   -- Adaptive network management services
   -- Quality of service (QoS)
   -- High availability
   -- IP multicast
   

3. Application layer: This layer includes business applications and collaboration applications. The objective of this layer is to meet business requirements and achieve efficiencies by leveraging the interactive services layer. This layer includes the following collaborative applications:
   -- Instant messaging
   -- Cisco Unified Contact Center
   -- Cisco Unity (unified messaging)
   -- Cisco IP Communicator and Cisco Unified IP Phones
   -- Cisco Unified MeetingPlace
   -- Video delivery using Cisco Digital Media System
