....Their scheme, ELSD (Equal Link Split Downstream) splits costs amongst downstream receivers and allocates no costs upstream. This is shown to be an optimal cost allocation for single source sessions with a source rooted tree, but requires changes to the IP multicast service. ELSD is modified in [16] for multiple source sessions, at the expense of some scaleability. It is not clear, however, that ELSD works for dynamic sessions. EXPRESS [18] modifies IP multicast for large scale single source applications. Multiple source sessions are catered for by a session relay approach, where all ....

....to lie about the number of receivers. This problem still exists with split edge pricing, however, since senders and receivers settle claims after transmission, and nomechanism is provided for verifying the number of downstream receivers. This is the collusion prevention axiom of Herzog s thesis [16], which also states that this problem cannot be solved through cost allocation alone. Einsiedler et al. 13] propose assigning weights to each link in a network, to represent the cost of that link. These weights can be derived from the congestion along the link, the costs of maintenance, or ....
