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

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

Switch. Organization’s policy. Distribution layer  Wiring closet conncetions and uses switch to segment workgroup and isolate network. The hierarchical model is useful for small network. Provides policy-based connectivity.Cisco hierarchical network model Access layer  This layer is used to grant user access to network devices. Enterprise composite network model  Enterprise Campus  Building  Building Distribution  Core  Server Farm  Management  Edge Distribution  Enterprise Edge  E-Commerce  Corporate Internet  Vpn And Remote Access  Wan  Service Provider Edge  Isp  Pstn  Frame Relay / Atm . Core Layer High speed backbone.

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

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