Cisco IIN and SONA Framework
IIN Intelligent Information Network Phase 1: Integrated Transport Data, Voice and Video consolidates onto an IP network for secure network convergence. Converge into a single standard-based modular network, can simplify network management and generate enterprise worldwide network. Cisco Unified Communications solutions Phase 2: Integrated Services When the network infrastructure is efficiently converged, the IT resource can be pooled and shared or Virtualized. Business continuity is also enhanced because in the event of a local system failure the shared resource on the IIN can provide needed services. Phase 3: Integrated applications This phase focuses on making the network application aware so that it can optimize application performance and more efficiently deliver networked applications to user. AON Application oriented networking.

Cisco SONA framework

This architecture allows the enterprise to scale without major change to the infrastructure. elastic multilayer design. MPLS. storage. video and data service over a single network. virtualization. or data voice and vice at same time) Enterprise sotware. .Application Layer  Identify the business requirements an achieve efficiencies by leveraging the interactive service layer. High availability. MPLS. VLANs. QoS. Teleworker This architecture allows the enterprise to securely deliver voice and data services to remote SOHO Wan Convergence of voice. Understand what type of application the network must support (only voice. IPsec. Cisco Networks Model Cisco enterprise architecture      Campus Data center Branch Teleworker WAN Campus It’s a combines of a core infrastructure of intelligent switching and routing technology. Ip-Multicast. redundant WAN links. Network Infrastructure LayerThe physical infrastructure. IPsec. Redundant server and link for backup and load balancing for increase the performance. on-demand computing (support hosting & housing). Integrated security with 802. high redundancy of software and hardware and automatic procedures for reconfiguring network paths when failures occurs. Advanced routing . In this case the use of ISRs (integrated service routers) can make available new services without buying new routers. local IP phone and all with higl level of resilience (elasticità) for all branch office. This architecture provides secure access to voice. mission critical data and video applications.1x port based network access control standard and EAP. Branch This architecture allows to extend the enterprise services to thousand office or a small group of branches. Qos. Level of security. Interactive service layer  In this layer are represented the functionality by making resource available to application and business processes. redundancy and so on. Data center Adaptive network architecture which support business continuance and security when enabling new service-oriented architecture. VPNs. VLAN.

Switch. Core Layer High speed backbone. Provides policy-based connectivity. The hierarchical model is useful for small network. Distribution layer  Wiring closet conncetions and uses switch to segment workgroup and isolate network. Organization’s policy.Cisco hierarchical network model Access layer  This layer is used to grant user access to network devices.

Management represent the network management functionality. logging. Edge distributionThis modules concentrate connectivity between all the branches and teleworker. Corporate Internet Provides Internet access for the organization.Enterprise Campus Hierarchical. DSL. and core principles are applied to these modules appropriately. Building distribution  distribution Sw L3 to provide access between workgroup and to the core. Monitor. Server Farm Data center. security and other management feature. and passes VPN traffic from external users to the VPN and Remote Access module. Building Contains access switch. MPLS and wireless bridging . highly robust campus network. Core Or backbone. Enterprise Edge This area it’s the interface between the enterprise campus functional area and the service provider edge functional area. end-user devices. distribution. Access. VPN and Remote AccessVPN and external users. provides high speed connectivity between building. WANProvides connectivity from remote sites using various WAN. server farm and edge distribution modules. E-commerceAll the network devices for an organization to provide full e commerce functionality. cable. Service Provider Edge ISPInternet connection PSTNNon permanent connections Frame/ATMAll Permanent connections to remote locations such leased line.

Creating an implementation plan using PPDIOO method PreparePlanDesignImplementOperateOptimize The first 3 step are realized by the project manager. (Optimize) . The other step are realized by a technician. (Plan) Characterize the existing network and sites.Creating. and executing an implementation Plan Ad Hoc  Work On field method. a prototype of network it’s realized. Step3. business and technical requirements. Step2. Plan the Implementation. Implement and verify the design. Structured approach  Planning as the first step. without planning any of the task. A good implementaztion plan is required to avoid such difficulties. All potential changes are reviewed and documents. Step 1. Step 1. (Operate) Step 3. Documenting. Monitor and optionally re-design. (Design) Design the network topology and solutions. (Prepare) Identify customer requirements. (implementation) Step 2. Network Analysis.
