Rev 2.3 (Jul 99)
MPLS (Tag Switching)
• Deployed within a device
• Deployed at network edge for
high-performance network
services:
—QoS policy
—Security
—Traffic accounting
• Used across the network
• Deployed at network core
for high-performance

MPLS (Tag Switching)
• Combines
– Layer 3 routing—scalability and
flexibility
– Layer 2 switching—high performance
and traffic management
• Multiprotocol Label Switching (MPLS)
– Emerging industry standard

Per-Virtual Circuit Queuing
• Virtual Circuits / Channels
– Logical circuit to ensure reliable
communication between two
network devices
– Used in ATM, Frame Relay, X.25
• Per-VC Queuing
– Queuing and flow control on a Per-VC basis
– Accommodates large bursts of incoming
frames
– Provides user and traffic “firewalling”
– Enables network to provide performance
guarantees for different types of traffic
– Allows the network to buffer incoming data
