When revenue per bit starts falling and cost per bit starts increasing, it’s time to think about alternative strategies to expand Transmission/IP network. As IP is predominant traffic in Transmission networks, therefore any expansion strategy on Transmission should be driven by IP demands. Indeed, both IP and Transmission departments need to work for a joint and synergetic […]
What your DWDM vendor did not tell you about latency for your Data Center Interconnect
Are you concerned about latency in your data center links running over optical network ? Or, are you planning for Data Center Interconnectivity in near future and want to know the impact of delays involved. The read on, for some useful tips to know your options. Chances are, you are already using DWDM to […]
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 […]
Does P-OTS 2.0 address operators’ needs?
Research firm, Heavy Reading, defines “P-OTS as a platform that combines SONET/SDH, connection-oriented Ethernet, DWDM and, depending on where the platform is used within the network, also optical transport network (OTN) switching and reconfigurable optical add-drop multiplexers (ROADMs)” As per Heavy reading, there is a growing trend now, with more and more operators asking about […]
400G is decided to be the next rate after 100G
The past year was hectic in terms of discussions regarding what could the next client rate for Ethernet and at the same time discussions were going on to decide the next line rate. There was a debate on whether the industry should go for 400GE or jump straight to 1 Terabit. Earlier in the same […]
