Line cards need packet based demultiplexing, space switch needs to be reconfigured on a packet-by-packet basis, need buffering Inherits complexity of packet switches. But aside from that it’s free.

Once a frame is received correctly, consult routing table with destination MAC address 4. Rearrange leading bits at end 3. Optical Channel Payload Unit Courtesy: Some switches cannot modify labels lambdas May want to restrict choice based on tutkrial resources Advertise available lambdas using Label Set Label set tytorial allowed to have just one member 39 Reducing Set-up Latency Some optical switches are slow to program Suggested Label shows choice at upstream Allows signaling to be pipelined May require reprogramming later Path Path Path Suggested Label?

The issue with this framing technique is that if the flag pattern occurs in the payload, an escape tytorial has to be inserted —This causes an increase in the required bandwidth —The amount of increase is payload-dependent page 98 of reference.

In connection-oriented packet- switched networks, —bandwidth allocation to a virtual circuit is independent of label mgpls In circuit-switched networks, —when “labels” are selected e. Construct setup message to send to next hop. This could be more than 1.
