Services Using E-Tree Service Type

Allow root-root and root-leaf communication (but not leaf-leaf) Provide traffic segregation for cloud or franchise networks. EP-Tree requires dedication of the UNIs to the single EP-Tree service. EVP-Tree allows each UNI to support multiple simultaneous services. EP-Tree. EVP-Tree. UNI. CE. UNI. Rooted-Multipoint EVC. Rooted-Multipoint EVC. Multipoint to Multipoint EVC. Root. Leaf. Subscribers with multiple sites may want to interconnect them to provide services other than those that resemble a LAN. These services may be distributed from a centralized site (or few such sites) where the distribution site is designated as a Root and all the remaining sites are designated as leaves. The EP-Tree service is defined to provide CE-VLAN tag preservation and tunneling of key Layer 2 Control Protocols. A key advantage of this approach is that the Subscriber can configure VLANs across the sites without any need to coordinate with the Service Provider. Each interface is configured for All to One Bundling and, therefore, EP-Tree service supports CE-VLAN ID preservation. In addition, EP-Tree supports CE-VLAN CoS preservation. Some subscribers desire access to certain applications or content services from well-defined access points within their own (or an external) network. In this case it is necessary to interconnect the participating UNIs in a Rooted-Multipoint connection to the well-defined access (or root) point. One or more of the Subscriber\u2019s UNIs may also support other services, e.g., EVPL or EVP-LAN. For such cases, the EVP-Tree service is used. CE. Root. Leaf. Leaf. UNI. UNI. CE.
