• application-layer multicast
• hierarchical Fibonacci tree
• underlying topology
• large multicast group

A scalable and efficient tree structured application-layer multicast protocol-FTALM (Fibonacci tree application-layer multicast) was proposed. By recursively partitioning the member sequences into two halves with different lengths, a hierarchical Fibonacci tree was built to multicast packets efficiently. In FTALM, the underlying topology characteristic was considered by introducing an idea of local area to reduce packet delivering on costly links. Moreover, the size of each local area was taken into account when constructing the hierarchical architecture in order to obtain a balanced architecture. The consideration of underlying topology and the construction of Fibonacci tree improved the delay performance of FTALM. The simulation results show the benefits of FTALM and demonstrate that it works well especially for large multicast groups.
