What do you mean, the size of the virtual container?

Hey? There is also a large bandwidth transmission demand of 1G/2G/4G/ 10GFC in the field of "underground-pit-security". Optical transport network needs to efficiently schedule, transmit and manage a large number of large particle broadband services to meet the needs of bandwidth operation. At the same time, the characteristics of broadband services also require the optical transport network to be dynamic, flexible, efficient, reliable and low-cost. Faced with these new demands, the traditional optical transmission networks (SDH and WDM) are very embarrassed: the traditional SDH transmission network has small traffic scheduling particles, limited transmission capacity and insufficient transmission demand for large-particle broadband services. Traditional WDM only solves the transmission capacity, but does not solve the problem of node service scheduling; At the same time, as a tool to expand the capacity and distance from point to point, the protection function of WDM networking and services is weak, which can not meet the needs of efficient, reliable, flexible and dynamic transmission of large-particle broadband services.
