When a threshold is met or exceeded, the network may be asked to take a variety of responses, from queuing packets at a lower service class to dropping them. Bandwidth allocation is driven by the weight assignments. It is a congestion-avoidance mechanism, set to prevent overloading by monitoring traffic load on an interface, not to manage it. It selectively discards lower-priority traffic when the interface starts to get congested. It even slows according to service class, so low-priority traffic is slowed first.
Security goes beyond sophisticated firewalls.
Its protection of information is based on tunneling at layers 2 and 3 and enables secure private communications over the Internet or any IP network. It ensures confidentiality, integrity, digital certification and authenticity for secure data encryption. Labels are applied at the edge, with no impact on the customer addressing or routing schemes.
