13.3.1 Layer 2 Interoperation Service Between Enterprise Branches
Different branches of an enterprise can achieve Layer 2 interoperation through ONUs. Then,
different branches can transmit service traffic to each other just like in the same LAN, which
can improve coordination work efficiency.
13.3.1.1 Service Requirement and Application Scenario
Service Requirement
An enterprise that has multiple branches requires intercommunication between different
branches or between its headquarter and branches. Virtual private network (VPN) can achieve
secure interconnection but requires additional devices and complex management. It requires
high costs even if a leased VPN is used. In addition, the bandwidth provided by a VPN is limited
due to restricted VPN access modes and the bandwidth control is inflexible.
To address the preceding problems, the Layer 2 interoperation technology using fiber access is
put forward and becomes the main trend.
Application Scenario
As shown in Figure 13-1, ONUs are deployed in branches of an enterprise. The ONUs access
and converge Ethernet services of the enterprise through FE/GE ports and transmit the services
to the OLT. The OLT implements Layer 2 interoperation between different branches of the
enterprise.
ONUs supporting this scenario: MA5612, MA5628, MA5616
