Secure, multi-tenancy aware and bandwidth-efficient data center multicast

摘要

Methods and arrangements for providing multicast communication. There is defined a first multicast tenant group comprising a plurality of hosts distributed over a plurality of locations. Communication is established with respect to the first multicast tenant group via: defining a routing tree, and using a multicast address space for communication with the hosts via the routing tree. The multicast address space is reused with respect to a second multicast tenant group. Other variants and embodiments are broadly contemplated herein.

1. A method of providing multicast communication, said method comprising:
defining a first multicast tenant group comprising a plurality of hosts distributed over a plurality of locations; establishing communication with respect to the first multicast tenant group; said establishing of communication comprising: defining a routing tree, the routing tree comprising a first routing tree; using a multicast address space for communication with the hosts via the routing tree; and establishing a first set of forwarding rules for the first multicast tenant group; reusing the multicast address space with respect to a second multicast tenant group; said reusing comprising distinguishing between traffic belonging to the first multicast tenant group and the second multicast tenant group, respectively; defining a second routing tree with respect to the second multicast tenant group, the second routing tree being different from the first routing tree; and establishing a second set of forwarding rules for the second multicast tenant group.
