Abstract
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.
Claims16
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.

An apparatus comprising:
- at least one processor;
- and
- a computer readable storage medium having computer readable program code embodied therewith and executable by the at least one processor, the computer readable program code comprising:
- computer readable program code configured to define a first multicast tenant group comprising a plurality of hosts distributed over a plurality of locations;
- computer readable program code configured to establish communication with respect to the first multicast tenant group, via:
- 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;
- computer readable program code configured to reuse the multicast address space with respect to a second multicast tenant group, the reusing comprising distinguishing between traffic belonging to the first multicast tenant group and the second multicast tenant group, respectively;
- compute readable program code configured to define a second routing tree with respect to the second multicast tenant group, the second routing tree being different from the first routing tree;
- and
- computer readable program code configured to establish a second set of forwarding rules for the second multicast tenant group.

A computer program product residing in a non-transitory computer readable medium comprising:
- a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
- computer readable program code configured to define a first multicast tenant group comprising a plurality of hosts distributed over a plurality of locations;
- computer readable program code configured to establish communication with respect to the first multicast tenant group, via:
- 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;
- computer readable program code configured to reuse the multicast address space with respect to a second multicast tenant group, the reusing comprising distinguishing between traffic belonging to the first multicast tenant group and the second multicast tenant group, respectively;
- computer readable program code configured to define a second routing tree with respect to the second multicast tenant group, the second routing tree being different from the first routing tree;
- and
- computer readable program code configured to establish a second set of forwarding rules for the second multicast tenant group.

A 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 first routing tree;
- establishing a first set of forwarding rules for the first multicast tenant group;
- and
- using a multicast address space for communication with the hosts via the first routing tree;
