Cost

In order to determine how to use site links, the Active Directory enables you to assign a cost to the link. This cost is considered a logical cost in that it defines bandwidth usage. For example, a T1 link would have a much lower cost than a 56 Kbps dial-up connection because the T1 link has much more bandwidth available. So, in terms of the Active Directory the cost of a link is based on the amount of available bandwidth. Low-cost links are defined as those that have a higher amount of bandwidth and are more reliable. High-costs links have less bandwidth and, perhaps, lower reliability. The Active Directory uses the cost information to determine which links to favor. For example, suppose you have two sites, one in Seattle and one in Tampa. Between those sites, you have a 1.54 Mbps connection and also a 256 Kbps connection. The 1.54 Mbps connection should have a lower cost than the 256 Kbps connection because more bandwidth is readily available. So, when you create these two site links, you assign a low cost to the T1 connection, such as a cost of 10, while you assign a higher cost to the 256 Kbps

connection, such as 100. With these cost factors, the Active Directory will always attempt to use the T1 connection over the 256 Kbps connection. If the T1 connection is unavailable, only then will the 256 Kbps connection be used.

You are not required to have multiple site links between sites, but providing at least two site links, such as a primary link and a backup link, gives you fault tolerance in case the primary link fails.

Aside from bandwidth, you can also base cost on other factors. For example, let s say you have two 256 Kbps site links between two sites. Each link has the same available bandwidth, but one link is less reliable than the other. You can use cost to favor the link that is more reliable over the link that is less reliable. Consequently, a number of cost issues could come into play. The point to remember is that the cost you assign to a link enables you to tell the Active Directory to use certain site links first, and others second. This is one way you help the Active Directory determine how to use site link information.

Frequency

When you create a site link, you can determine how often replication should occur over the link. For example, you can tell the Active Directory to replicate over the link every 15 minutes, every hour, every three hours, and so forth. In reality, the Active Directory uses pull replication, which simply means that domain controllers pull replication data from other domain controllers instead of having it forced on them through push replication.

The frequency interval you input determines how often a domain controller can poll another domain controller over the site link for replication updates. If you have ever worked with replication in a WAN environment, you know that it is a juggling act of sorts. You want replication to occur as frequently as possible to reduce the amount of time when domain controller databases are out of sync due to database changes (called latency). However, you should consider the following questions about your WAN connection: How much traffic can it handle How often is it available Is the WAN connection costing your company money each time it is used You must weigh all of these factors and determine a frequency value that is right for your network and, ultimately, your users. The good news is that the frequency of a site link is easy to configure and easy to change, so you may have to do some experimenting to determine what works best for your network.
