What Is Committed Access Rate (CAR)?

When working on the road, there are many things to consider. You want to ensure your data is secure, your team is in sync, and you're not wasting time on things that don't matter. But how do you know what to focus on? That's where the Committed Access Rate (CAR) comes in. CAR is a feature from Cisco that can help you optimize your network and ensure that your team members use the right tools for the job. It lets you limit the input or output traffic rate on an interface or sub-interface based on IP precedence, IP access list, or incoming interface. When the traffic reaches the set limit, CAR specifies specific actions to be carried out. These actions can be configured using CAR commands that use values for traffic rate limit, burst rate allowed, and effort to be performed when the traffic reaches or exceeds the set limit. Have you ever been in a situation where your data was so important that you had to get it to the recipient, but there was too much? You know what I'm talking about. Sometimes you need to send many data at once. It could be the results of a complex analysis or a huge file. Your boss may have emailed you a document with all the new guidelines for the department, and he said to email him back as soon as possible with your opinion on each one. There's no denying that sometimes you need to go HAM on sending information through email. But what happens when all of that data starts coming in? What if it doesn't stop? What if my boss says, "send me everything," and then sends me another document with more guidelines? And then another one after that? And then another one after that? Well, we have a problem—and we're here to help! Precisely because we understand how terrifying this scenario can be (and because we're good at math), we've created a committed access rate (CAR). This feature allows users to set limits for incoming emails based on their unique needs and preferences.
