在另一个地方看到选的BCF 的解释：

Four technical services are essential to supporting the high level of flexibility, resource availability, and transparent resource connectivity required for cloud computing:
+ The Layer 3 network offers the traditional routed interconnection between remote sites and provides end-user access to cloud services.
+ The extended LAN between two or more sites offers transparent transport and supports application and operating system mobility.
+ Extended SAN services support data access and accurate data replication.
+ IP Localization improves northbound and southbound traffic as well as server-to-server workflows.
