Are you a transport or a mobile backhaul operator with a goal to deploy easy to operate Ethernet transport solution based on MPLS-TP? Do you know that you may run into potential surprises if you treat MPLS-TP as any other technology you evaluate. In fact, not all systems are equal, and this is particularly true about MPLS-TP gear. MPLS-TP hadn’t had a smooth […]
Three things, Operators should know about combining Protection on IP/MPLS and Optical Layers.
If an Operator decides to deploy Multi-layer protection using both IP/MPLS and Optical domain, he faces a number of challenges: IP/MPLS and Optical control planes work separately in transport networks; they are, usually, disjoint and do not communicate with each other. IP/MPLS circuits are provisioned as one of the services for optical layer with no co-ordination between them. While the “disjoint” protection strategy may work.but it is NOT […]
RSVP-TE and OSPF-TE extensions for GMPLS
Packets in MPLS are routed according to preconfigured label switched paths (LSPs). When packets are received, label lookup is performed from which it is identified to which LSP packets belong to and hence it identifies the next hop of the packet. GMPLS generalizes the concept of MPLS. Instead of the concept of labels, GMPLS uses […]
Essentials of ASON GMPLS
A presentation I created a while ago on basics of ASON GMPLS
Optical ASON or Electrical ASON!
The debate still lingers on. When it comes to protection and re-routing on High speed links, what is the benefit of using Optical ASON versus Electrical ASON. The Optical ASON relates to lambda switching ( Also called WSON-Wavelength Switched Optical Network). This necessitates the need of using at minimum Multi degree and directionless functionality. Using colorless […]
