  4. Service Level Agreement The same is true for communication services. In addition to the pure functionality, each service is defined by a multitude of characteristics, which can be expressed as parameters. Those parameters can relate to performance: How much bandwidth is available are we talking about 10 Mbps or 1 Gbps? How long is the delay from the time when you pick up a phone to when you hear a dial tone will you always get the tone within half a second, or are there times when you will have to wait for half a minute? Other parameters can relate to capacity: How many transactions per second does your web-hosting provider support? Parameters can also relate to availability: Is the service guaranteed to always be available, or are there times when it can be down ? If so, how long will it be down, and how often do such outages occur is it once a year only, or can it occur more often than that? Are outages announced beforehand so that you can plan around them, or do they happen unexpectedly?
