Components in each layer can be used to create networks specialized in providing one type of service. For example, multiprotocol network bandwidth and SNA network bandwidth could be provided by a single T1/T3 or E1/E3 network infrastructure. This common infrastructure could be made up of resource managers providing lower-speed interfaces to other network applications (e.g. voice, video, etc.). This analysis seeks to capture information relative to the costs and deployment of such common infrastructure components and the efficiencies derived by each covered networking type from the use of common facilities, services and negotiated contracts. Two types of networks are distinguished in the analysis: hierarchical and multiprotocol (peer-to-peer). Hierarchical networks are host-centric, that is, all traffic flows between one (or more) mainframes and end-user devices in a point-to-point or multipoint configuration. SNA or Poll / Select type networks fall into this category. In a multiprotocol network, which is network-centric, traffic flows through bridges, switches, or routers in multiple directions. All devices can communicate through the network using a variety of protocols. TCP/IP networks fall into this category. These networks may also provide terminal- to-host communication by encapsulation or other techniques. Version 2.6 1 ITB/WAD General Definitions, continued Wide Area Data Workbook The workbook is comprised of one spreadsheet: Wide Area Data. In Wide Area Data, we will collect information pertaining to workload, cost and personnel for your wide area data network. Version 2.6 2 ITB/WAD Wide Area Data The Wide Area Data work sheet will define the workload, cost and personnel components of your analysis. This will be used to select the comparison group and will be balanced against your costs to determine your overall efficiency metrics. Workload profiles are defined by sites, devices able to originate and / or terminate traffic across the wide area network (WAN), and the traffic load carried by the WAN. Identify the currency for the costs you are entering on the Currency line at the top of the spreadsheet. 1. Workload Definition – Number of Sites (Row 1; Columns A, C and E) Report the number of hierarchical sites in Row 1, Column A; multiprotocol sites in Row 1, Column C and other sites in Row 1, Column E. A site is defined as a single organization facility located on a continuous piece of property that is not crossed by a public thoroughfare. This is the demarcation point where the wide area network (inter-site) ends and where local, or premise-based, (intra-site) services begin. A site with separate physical connectivity to each network should be counted for both environments. 2. Workload Definition – Number of Devices (Row 2; Columns A, C and E) Report the number of hierarchical devices in Row 2, Column A; multiprotocol devices in Row 2, Column C and other devices in Row 2, Column E. Devices are those types of equipment that may either originate and / or terminate traffic across the WAN. This category includes, but is not limited to, physical terminal types, printers, desktop computers, workstations, servers, gateway sessions, dial- up ports, midsize computers, mainframe computers and super computers. Devices are classified by how their traffic moves through the network (i.e., hierarchical or multiprotocol). No device may be counted twice (questions in this area should be resolved with your KPMG LLP Analyst) regardless of its ability to pass traffic on more than one network. For example, the devices connected to a cluster controller whose traffic passes through a router will appear in the multiprotocol device count. This is due to the fact that these devices are generating traffic on the multiprotocol network. Devices that are connected to a cluster controller whose traffic passes through the hierarchical network will appear in the hierarchical device count. 3. Workload Definition – Traffic (Row 3; Columns A, C and E) Report the number of gigabytes for an average month transmitted across the hierarchical network in Row 3, Column A; multiprotocol network in Row 3, Column C and other networks in Row 3, Column E. Data traffic excludes all video and voice applications even if they are digitized and transmitted through a network. Protocol overhead as well as polling and acknowledgments, however, are included. As in the case with devices, traffic must only be counted once. Therefore, if you have both hierarchical and multiprotocol networks, you must be sure to reduce the hierarchical traffic measurement by an amount equal to the that of host-bound traffic carried by the multiprotocol network. Version 2.6 3 ITB/WAD Wide Area Data, continued When counting the network traffic on a hierarchical (SNA) network, include both inbound and outbound traffic measured at the host FEP level. Traffic is measured in megabytes using standard counters in the FEP. This can be done through the software such as NetSpy, etc. Actual data volumes are desired. If this is not available, measure over a one-week period during a "typical" workweek (defined as 7 by 24). Multiply the resulting number by 4.33 to obtain an estimate of monthly traffic. Describe the methodology used to determine the volume. You must be sure to reduce the hierarchical traffic measurement by an amount equal to the that of host traffic carried by the multiprotocol network and completed via the FEP. 0 0When counting the network traffic on a multiprotocol network, include all network-generated data traffic on the WAN serial link registers on the routers. Since this will include traffic from both input and output registers, divide the total by two. Actual data volumes are desired. If this is not available, measure a one-week period during a “typical” workweek (defined as 7 by 24). 0 1. Workload Definition – Percentage of Redundancy (Row 4; Columns A, C and E) 0 0Report the percentage of bandwidth reserved for redundancy for the hierarchical network in Row 4, Column A; multiprotocol network in Row 4, Column C and other networks in Row 4, Column E. Some amount of redundancy is usually built into most data networks to ensure continued network availability during circuit failures. This is bandwidth that is reserved for the rerouting of traffic from failed circuits, links or equipment. 0 1. Workload Definition – Percentage of Availability (Row 5; Columns A, C and E) 0 0Report the percentage of availability your network is designed to achieve for the hierarchical network in Row 5, Column A; multiprotocol network in Row 5, Column C and other networks in Row 5, Column E. This should include downtime for scheduled maintenance procedures. Given the business requirements of your enterprise, you must design your network for a required (or expected) level of availability (for example, 99.5% availability, 7x24). 0 1. Cost Definition – General 0 0KPMG LLP uses fully burdened costs when defining costs for the consensus cost models. Include the lease, maintenance and depreciation costs of all hardware, software or shared hardware and software used by the wide area data network staff for the analysis time period. In all cost categories, include all applicable taxes (federal, state and local). Include value-added taxes (VAT); only exclude VAT when it is recovered or refunded to the organization. All costs are reported in thousands. 0 0The depreciation schedule used and the tax rates borne by your organization are reported in the ITB Project Definition and Information Questionnaire. 0 Version 2.6 4 ITB/WAD Wide Area Data, continued 1. Cost Definition – Hardware (Row 6; Columns B, D and F) 0 0Report the annual monetary expense related to hardware for the hierarchical network in Row 6, Column B; multiprotocol network in Row 6, Column D and other networks in Row 6, Column F. Include costs for modems, CSU / DSU, dial backup, protocol converters, T1/E1 muxes, packet switches, PADs and FRADs, routers, font end processors, etc. Also include the costs of dedicated CPU for communication management control (CMC). A network CPU is a CPU with functional responsibility to run the network to allow network devices to access applications on CPUs. This is not a network administration function but is true dedicated communication management control. 0 1. Cost Definition – Software (Row 7; Columns B, D and F) 0 0Report the annual monetary expense related to software for the hierarchical network in Row 7, Column B; multiprotocol network in Row 7, Column D and other networks in Row 7, Column F. Include VTAM and all software running on FEP, switches, routers and other uploads/Ingenierie_Lourd/ guide-wadata.pdf
