Multiplexer-transport mechanisms to force an Ethernet traffic from a domain to switch in a different domain (external)

摘要

A network (120) comprising: a switch (124) in a second network domain (120) configured to switch traffic between a plurality of external interfaces (112) in a first network domain (110) via a plurality virtual interfaces of said switch being associated with the external interfaces (112) in the first network domain, wherein the traffic comprises a plurality of network identifiers virtual local area, VLAN, external VIDs associated with the internal interfaces and said switch (124) identifies and selects virtual interfaces based on the external VID to send traffic, and wherein the virtual interfaces (122) are configured to forward traffic based on an internal VID that is assigned to traffic independent external VID.
