Short Answers
Availability and reliability
The difference between availability and reliability is how each are measured. Availability is the amount of time a system is available during a period of time not including downtime for the system. The formula for this is calculated by the time between failures divided by the time between failures plus the time to repair. This gives you a percentage which gives you the percentage of time available. Once availability begins to get tracked by a vendor, reliability can be determined factoring in hardware life cycles and user additions.
Response time and throughput
Response time is the amount of time that it takes for a user to execute a single query. Sometimes this includes the time it takes for that query to be returned versus how much time it takes to run an entire query. Throughput is the measurement of what is happening when several users are sending queries at the same time and how it affects the network. Throughput is configured by the amount of data that can be transmitted and divided by the time it takes to transfer it.
Throughput and bandwidth
Throughput is the measurement of what is happening when several users are sending queries at the same time and how it affects the network. Throughput is configured by the amount of data that can be transmitted and divided by the time it takes to transfer it. Bandwidth is the maximum amount of information that can be transmitted on a line.
SNMP and RMON
SNMP is responsible for monitoring and managing network hardware such as hubs and bridges. RMON monitors the actual traffic segment on a local area network.

Abstract
A good network should have appropriate service level in several areas of implementation and purchase. Among the areas that should be reviewed are availability, reliability, response time and throughput. The following information helps to explain how to establish proper levels in each of these areas...
