TE Design Considerations
A full mesh of sub-pool and global-pooltunnels providesmaximum benefit:
Optimal use of VoIP classbandwidth
Admission control and constraint on per link VoIP utilisation for tight VoIP SLA
Optimal use of Business and BE class bandwidth
All traffic is accounted for - tunnel counters inherently produce a complete backbone traffic matrix
Pop-to-pop mesh more scalable than PE-to-PE
