How does a "Chaining" method function in E-TREE services?

In E-TREE services, the "Chaining" method is designed to facilitate communication between multiple customer sites while preventing any direct connections between them. This method is particularly useful in scenarios where a hierarchical structure is needed, such as when certain sites should be able to communicate with a central point but not with each other.

By allowing traffic to flow among several customer sites, "Chaining" establishes a framework where interaction can happen without creating direct paths between those sites. This helps maintain the desired network policies and limits. For instance, in a business environment, branch offices may need to communicate with a corporate headquarters, but they might not require or be allowed to connect to each other directly.

In contrast, while restricting traffic to a single path, allocating bandwidth, or aggregating traffic to a central location may have relevance in certain contexts, they do not accurately capture the essence of what "Chaining" accomplishes in E-TREE services. The primary focus is the ability to facilitate controlled communication among multiple endpoints with limitations on direct inter-site traffic.
