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

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

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

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

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