Patent ID: 8060598

Claim:
A method of monitoring multicasting traffic in a network between a multicasting source in a first domain and a multicasting destination in a second domain, wherein said multicasting source offers connections to a predetermined multicast stream according to predetermined multicast group information, said method comprising the steps of: said multicasting destination sending a join message to a router within said network in order to initiate routing of said predetermined multicast stream to said multicasting destination; sending a notification of said joining from said router to a ledger application, said notification including identifying information of said multicasting destination and said multicasting source; said multicasting source transmitting datagrams of said predetermined multicast stream to said multicasting destination via said router; said ledger application receiving and logging said notification as a transaction event; and sorting transaction events according to said first domain of said multicasting source and according to said second domain of said multicasting destination, wherein said sorted transaction events identify a reimbursement of costs between domains for transporting said multicasting traffic.
