MPLS: Power and Complexity Oscar Cetina Network Engineer at Foxtel MTIM, B.E. Telecommunications CCNA – CCIP - CCNP Professional Background Network Engineer Operations Engineer NOC (Network Operation Centre) Engineer Focus: troubleshoot and resolve as fast as you can. 80% reactive Focus: Maintain optimum performance of the network Focus: Prevent potential issues and prepare the network for new technologies or services. 80% proactive Me @ Foxtel Broadcasting IPD Streaming Corp Network Engineering (layer 1 - 4) Internet Customers Partners Vendors Security My Role BAU Activities Network Support Projects/ Presales Technical feasibility Change implementation Resource allocation Network expansion Documentation/closure Capacity planning Implementation Stock management Network design/testing Network Expansion/Migration Project How to interconnect these two organisations? Providers Providers Network Expansion/Migration Project Network Expansion/Migration Project OSPF BGP MPLS Not escalable. High overhead. Escalable but no granular enough Specialised equipment. Too many databases. MPLS Constraints/Complexity Requires (IGP) OSPF and BGP to work Requires VRF (Virtual Routing Forwarding) to work Creates more than 5 routing/switching tables Specialised knowledge to design, implement and troubleshoot Advantages/Power Minimal migration disruption if well-planned Does not require changes on the existing routing protocols/IP address allocation Easy integration regardless vendors or protocols Ideal for customization: Offers virtual/customised routing for a great deal of customers in 1 device when configured through VRF (MPLS/VPN) Simple from the user perspective (compare to smartphones) Challenges QoS implementation, even more complex due to mapping mismatch from the IGP Adding features to simplify particular services Control and monitoring of MPLS devices My contribution Solving problem skills Looking outside the box Analytical thinking My contribution Vs.
