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 […]
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 […]
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 […]
What is it that operators miss on 100G optics/transponders ? Is it reach, cost or availability ? In fact none of them.Telecom Lighthouse We have Coherent optics that can span thousands of kilometers, and we have prices getting competitive reasonably, so what is it that operators would still want on 100g optics. Read further. What operators want, is an efficient solution […]
When it comes to QoS in Packet Transport environment, Queuing mechanisms insides switches and routers hold key importance.There are a variety of methods used by manufacturers.So which Queuing mechanism is best for QoS for routers and switches. There is no clear answer to that because every queuing mechanism has certain Pros and Cons. I have summarized main […]
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 […]
Today, I spent the day at Tellabs PoC (Proof of Concept) showcasing their DWDM and Mobile Backhaul portfolio. Tellabs had put up an impressive collection of equipment showing an array of portfolio including 7100 Nano, 7300 Carrier Ethernet portfolio and 8600 series for Mobile backhaul. I was particularly interested to see their backhaul equipment in action. […]
There are some confusions surrounding the differences between SDN and NFV. Both terms relate to virtualization of network; both are hot topics these days. Sometimes, one concept is mixed with the other. SDN stands for Software Defined Network. It is based on two pillars. Separation of data and control plane and centralization of control plane. […]
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 […]
API is the most powerful feature of SDN- the programmable network. It will open a world of opportunities in terms of flexibilities and features for both operators and app developers. The current networks are rigid and make operators “lock in” to vendors. SDN will help avoid this lock in by making a network a flexible […]
