Multi Protocol Label Switching Allot and MPLS

Multi Protocol Label Switching MPLS Smart, fast routing mechanism to solve routing table scalability issues Predefine paths for specific traffic types Scalable virtual private networks (VPNs) “E nd-to-end ” quality of service (QoS)

Does MPLS Replace Allot QoS Solution? MythsReality “I don’t need a dedicated QoS solution – I’m moving to MPLS” MPLS has become a connectivity technology and not a QoS technology. Allot and MPLS are complementary solutions. Allot completes the MPLS solution: Classifies applications (layer 7) – P2P; Citrix; VoIP. Signals the MPLS edge router with Diffserv. Shapes traffic on the last mile. Provides detailed monitoring and accounting.

By the book – MPLS TRAINING GUIDE By Rick Gallaher. “I personally prefer standalone components to perform policing and traffic accounting. The argument is as old as the stereo system arguments that pitted integrated systems against component-based systems. I like to have component-based policing and accounting, because it gives network analysts better control over their data. There are several policy-based policing “switches” on the market. I have had good luck with Allot’s NetEnforcer for policy-management and accounting purposes.” Rick Gallaher.
