Open the CIPO recordAbstract From the Canadian patent
A hierachy multicasting system (100) includes multiple clients coupled together in a tree structure (102) through a routing process (300). Data is transmitted from a data source (101) to a root node (112) of the tree structure (102). The root node (112) uses its up-link capacity to reflect the data to its children (122, 124). Through various filtering steps the routing , process (300) optimizes the tree structure (102) for efficiency and realibility. In addition, users (612, 622) behind different firewalls (610 620) may communicate with each other. Therefore they can be connected in the , same hierachy multicasting tree structure (600).

Why it's free to use
- Filed October 31, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 31, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 31, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
