Rick Gallahers MPLS Training Guide: Building Multi Protocol Label Switching Networks

1. 

Consider the following scenario. Your team is a group of highly paid consultants for a small, developing country. MPLS technology has been selected because of its traffic-engineering capabilities. This system will require traffic engineering to help manage increases in traffic as the network grows.

On the Web, research the benefits and drawbacks of ordered control vs. non-ordered control; then recommend a solution for the LDP protocol. What are your recommendations ?

2. 

Now do the following:Answer the following questions.

1. List your references.

2. List the advantages of ordered control.

3. List the disadvantages of ordered control.

4. List the advantages of non-ordered control.

5. List the dsadvantages of non-ordered control.

This group exercise and case study were designed for real-time study. The information listed below may change over time, so it is recommended that this research be conducted by each student of this course

Ordered control vs. independent control was not an issue at the time - just as cut-through switches vs. store and forward switches were not issues. The technology has advanced significantly since the start of MPLS. Currently several manufacturers offer independent control for start-up and ordered control after the network links are established
