Describe or list the activities and services involved in this Function (in the context of this Function). An activity or service can be provided by a computer system, a set of applications, or manual procedures. These activities/services should be described at an appropriate level, with the understanding that sub-activities and services should be described if they are important for operational issues, automation needs, and implementation reasons. Other sub-activities/services could be left for later analysis.

Activity/Service Name xiii

Activities/Services Provided xiv

Object management  - Defining resources and attributes

EnergyManagementSystem needs to be aware of resources: routers, hubs, computers,  and their attributes.

Defining,  modifying and examining relationships

EnergyManagementSystem needs to be aware of the object relationships.

Setting, modifying and examining  attribute values

Object attributes need to have values. E.g, number & types of ports per card.

Inventory Management

IM is the task  of maintaining types and configuration of resources. The inventory information is required for SW and HW maintenance, determination of faults and recovery, and capacity planning.

Network Discovery

Dynamically creates a representation of the network topology, and configuration of the devices. The data could be collected manually, which is very tedious and often not accurate for a large network, or though an  EnergyManagementSystem. Instances of the managed devices and their internal components are created and connections are made. Components and info on the devices include network cards, ports, interfaces, power supplies, MAC addresses, SW version, OS type, CPU types, IP addresses, etc.

Address Management

Address management includes allocation IP addresses to devices, determination of subnets, keeping track of  used and available IP addresses, and reuse of  unused addresses. This task reduces addressing complexities and waste of address space.

Name Management

Naming establishes a connection between a name and a device, its location, its type,  etc. Helps identify devices, IP address mappings, etc. Naming conventions for network devices, starting from device name to individual interface, should be planned and implemented as part of the configuration standard. A well defined naming convention provides the ability to obtain accurate information when troubleshooting. The naming convention for devices can use geographical location, building name, floor, and so forth. For the interface naming convention, it can include the segment to which a port is connected, name of connecting hub, and so forth.

Routing management

Determine and configure routing tables. This includes configuring  parameters for IP routing , Quality of Service, etc.

SW distribution and upgrade

This includes detection of SW releases, distribution of new releases, and testing for interoperability.

Setting & verifying user authorization

Scheduling, user/flow/packet prioritization

This is to allow for a specific treatment of users, flows, or packets based on availability of features on the routers, switches and computers to meet QoS  requirements or SLA’s.
