Tivoli Comprehensive Network Address Translator Helps Manage Multiple Networks and Tivoli Network Connectivity and Performance Manager Provides Network Status
At a Glance
Tivoli Comprehensive Network Address Translator (CNAT) enables integration of multiple networks with different IP addresses. When they use CNAT to resolve address conflicts between multiple IP domains, network administrators may gain:
Tivoli Network Connectivity and Performance Manager provides:
IBM announces two major programs from Tivoli® Comprehensive Network Address Translator (CNAT) and Network Connectivity and Performance Manager. Both of these tools provide important functionality to network users.
CNAT provides a powerful tool for enterprises that face the problems associated with managing multiple TCP/IP networks with conflicting IP addresses. Specifically, CNAT can help resolve these conflicts between multiple IP domains by translating the addresses for use within a single management domain. Therefore, a single network administrator can manage multiple networks with address conflicts.
In addition to translating the source and destination addresses between conflicting networks, CNAT evaluates management protocols for embedded IP addresses and translates these, enabling Tivoli NetView® to perform network management tasks transparently into TCP/IP networks.
Key Advantages of CNAT
With CNAT, service providers that use traditional and next generation IP networks can ease customer network acquisition. Industry users that must connect and manage numerous networks, such as banking/finance, pharmaceutical, insurance, and manufacturing, can help solve the problem of limited IP address space with the Tivoli CNAT solutions.
How CNAT and Tivoli Network Connectivity and Performance Manager Work
CNAT resolves IP address conflicts by mapping True IP addresses to Normalized IP addresses, which are valid within the managed domain. By residing between the service provider and each customer network, CNAT abstracts each customer's network addressing scheme details. Within the managed domain, all IP addresses appear as normalized. Network traffic is routed to its correct destination even though individual customer networks may be using overlapping addresses. This translation function works for all source and destination addresses, as well as providing bidirectional translation of SNMP and ICMP messages between the management domain and the conflicting IP addresses in a managed network.
Tivoli for Network Connectivity and Performance Manager monitors the connectivity and performance of IP routes. The IP routes can be diagnosed for connectivity problems, traffic bottlenecks, and adverse performance trends.
Tivoli Network Connectivity and Performance Manager also validates the IP route statistical data against user-defined Service Level Agreements (SLA) Web reports are generated describing SLA evaluation results, SLA violations, and potential future problems.
All historical data is kept in an open relational database. Tivoli Decision Support is used to create different reports and views against the historical data. Notification for significant events (IP route up/down, SLA violation, adverse trend) are sent via an SNMP trap.
Refer to the Technical Information section.
Planned Availability Date
The Tivoli Comprehensive Network Address Translator (CNAT) is designed to simplify the problems associated with managing multiple TCP/IP Networks which contain conflicting IP addresses. Some firewall products support network address translation which allows packets from one network to transverse into another, but the CNAT solution goes one step further, translating critical network management information (SNMPV1&ICMP) to increase the reach of TCP/IP Network Management Tools like Tivoli NetView.
Tivoli CNAT is installed between the management network and the network to be managed (the customer network), and integrated into the network topology. Every packet that travels between the management network and the customer network passes through CNAT where one of the following occurs:
Tivoli CNAT consists of three main components:
Tivoli for Network Connectivity and Performance Manager measures IP route availability and performance. Service Level Agreements may be created to validate the measured performance against user-defined service levels. This application allows you to set performance metrics, analyze trends, and monitor violations of an IP network.
With this application you can:
Tivoli Network Connectivity and Performance Manager allows you to monitor the availability, response time, and throughput of IP routes. The route to be monitored may be a simple IP route, which is monitored using ICMP Echo (ping) packets, or it may be a route to a web server, which is monitored using Hyper-text Transfer Protocol (HTTP) "Get" packets.
For each route, the following metrics are measured:
For simple IP routes, the number of bytes requested in the Ping packet is randomly assigned to be one of 64, 128, 256, 512, or 1024 bytes. For HTTP routes, the number of bytes includes the HTML file and any image files, sound files, movie files, style sheets, or other content which would be imbedded in the page by a Web browser.
For each monitored IP route, an "IP Route Down" trap is sent to Netview each time a route is detected to be unavailable, and an "IP Route UP" trap is subsequently sent when that route is detected to be available. For web server rotes, the route is determined to be available if the HTML page specified in the web server URL is accessible, even if some imbedded content (for example, image files) are not available.
In addition to simply monitoring an IP route, this application can compare measured performance against predetermined service levels, and alert you when values are received which violate the service levels. This Service Level Management allows you to provide users of your network (external or internal customers) with information about how well your network services meet their expectations or your guaranteed levels of service.
Each Service Level Agreements allows you to monitor five metrics:
For each of these metrics, you may specify threshold values. A service level violation is recorded when a monitored value exceeds (for network response time and MTTR) or falls below (for availability, throughput, and MTBSO) the threshold. When a service violation is recorded, an "SLA violation" trap is sent to Netview. For availability, network response, and throughput you may specify two separate threshold values, one for "Peak" periods, and one for "Off-Peak" periods. You can define what times of day, days of the week, and weeks of the month should be considered "Peak" or "OFF-Peak".
In addition to monitoring Service Level Agreements, Tivoli Network Connectivity and Performance Manager allows you to publish reports on each Service Level Agreement on a web server. By configuring security on your web server, you make some or all the reports available to customers, network administrators, and/or executives.
The Tivoli Decision Support Guide for Network Connectivity and Performance Manager ships with the product, this guide assists you in doing reports and trend analysis. Tivoli Decision Support is the base product required when using the different Decision Support Guide's from Tivoli.

Tivoli Management Points
Tivoli Management Points are used to compute the license quantities and are program specific. Points cannot be transferred among separate products.
The Environment-Managed model is used to describe the new Tivoli price offering that separates licensing from architecture. In an environment-managed model the price is based on what is managed rather than the more traditional approach of pricing based on the number and type of product component. Thus, a server is defined as a server by its use in the customer's environment, not by its use within a Tivoli application. For example, all print and file servers for which a customer is using Tivoli Distributed Monitoring to track performance require points sufficient for those servers.
A server is a computer system that provides services to one or more clients or other devices over a network. Examples include, but are not limited to, file servers, print servers, mail servers, database servers, application servers, and WEB servers. A server is defined by its use in the customer's environment, not by its use in a Tivoli application. Tivoli servers are tiered as defined in the Tivoli Server Tier Exhibit.
For distributed servers in a clustered environment, points require- ments are based on the size of each server in the cluster, tiered as defined in the Tivoli Server Tier Exhibit.
Tivoli Server Tier Exhibit
.-------------------+--------------------------------------. | Server | 32-bit Intel (or compatible) systems | | Tier 1 | with 4 or fewer processors | | | installed | |-------------------+--------------------------------------| | Server | RS/6000 systems with fewer than | | Tier 2 | 24 processors installed (Except as | | | spelled out in Tier 3) | | +--------------------------------------| | | Intel (or compatible) 64-bit systems | | | with less than processors installed | | +--------------------------------------| | | Intel (or compatible) 32-bit systems | | | with 5-23 processors installed | | +--------------------------------------| | | IBM AS/400(R) servers | |-------------------+--------------------------------------| | Server | Any distributed system with 24 or | | Tier 3 | or more processors installed | | +--------------------------------------| | | All HP V-Class Systems classes of | | | servers with 14 plus processors | | | installed | '-------------------+--------------------------------------'
A computer system or process that requests a service of another computer system that is typically referred to as a server. Multiple clients may share access to a common server. A client has some processing capability or is programmable to allow a user to do work. Examples include laptop computers, desktop computers, and desk side computers.
A network node includes routers, switches, hubs and bridges that contain a network management agent. In the Internet Protocol (IP), the managed node usually contains a Simple Network Management Protocol (SNMP) agent. A single node may contain any number of interfaces or ports.
A port is the interface via which network devices (hubs, concentrators, repeaters, routers and switches) are connected to a network through switches and routers.
For Tivoli products which scale based on ports, the following Tivoli Network Device Tier Exhibit applies:
Tivoli Network Device Tier Exhibit
.---------------------------+-----------------------------. | Network Tier 1 | Routers with less than or | | | equal to 25 ports | | +-----------------------------| | | Switches with port density | | | of less than or equal to | | | 50 Ethernet or | | | Token Ring ports | |---------------------------+-----------------------------| | Network Tier 2 | Routers with 26-50 ports | | +-----------------------------| | | Switches with port density | | | of 51-100 Ethernet or | | | Token Ring ports | |---------------------------+-----------------------------| | Network Tier 3 | Routers with 51+ ports | | +-----------------------------| | | Switches with port density | | | of 101+ Ethernet or | | | Token Ring ports | | +-----------------------------| | | All ATM, Frame Relay, and | | | all other WAN backbone | | | switches | '---------------------------+-----------------------------'
A registered user is defined as anyone who is authorized to access a Tivoli program.
Concurrent users are defined as the maximum number of users who access a Tivoli program at any one time.
For Tivoli Service Desk, Tivoli Problem Management, Tivoli Change Management, and Tivoli Asset Management a concurrent user includes any user accessing the application with create/update authority.
An application server is the computer system that provides services to on or more clients, servers, or other devices over a network and is defined by its use within the Tivoli application. For programs running on a distributed cluster of servers, points sufficient for an application server are required for each instance of the software rather than each individual server.
RS/6000 Scalable POWERparallel Systems® (RS/6000 SP)
An SP is any of the RS/6000 SP series of parallel computing servers. For Tivoli pricing, the SP is a Tier 2 server if it has fewer than or equal to 24 processors in aggregate in the system. For example, if a system has 2 nodes with 8 processors each (16 processors total), the system would be a Tier 2 server. As an alternate example, if the system has 3 nodes with 8 processors each (24 processors total), it would be a Tier 3 server.
A group of distributed servers operated as a single image, generally running in serial. Each system in a cluster is priced as a server, with the appropriate tier as determined by the Tivoli Server Tier exhibit.
Management Services Unit (MSU)
An MSU is defined as millions of CPU service units per hour; the measure of capacity used to describe the computing power of the hardware processors on which S/390® software runs. Processor MSU values are determined by the hardware vendor, IBM or Software Compatible Vendors (SCVs).
