ABSTRACT:
Methods and apparatus are provided for managing data communications between hosts (9) of a switched Ethernet network (8). Hosts (9) are assigned to logical groups of hosts such that the hosts participating in a data communication are assigned to the same group. In a switch (1) of the network, each group is associated with a service class indicative of requirements for forwarding data across the switch (1) for data communications between hosts (9) in that group. Data received by the switch (1) is forwarded across the switch in a manner dependent on the service class of the group to which hosts (9) participating in the data communication are assigned. In the switch (1), data communications between hosts (9) in one or more of said groups are disabled when required to satisfy the forwarding requirements for at least one said service class.
