How does Direct Connect support Link Aggregation Groups to increase bandwidth and provide additional resilience?
AdvancedAnswer
A Link Aggregation Group, or LAG, combines multiple individual Direct Connect connections into a single logical connection, both increasing total available bandwidth by adding the capacity of each individual connection together and providing resilience, since if one physical connection within the group fails, traffic continues flowing over the remaining connections in the group without requiring any manual intervention or reconfiguration.
