(T) I have been trying over the years to follow the evolution of Google’s datacenter and networking technologies, and in particular its switching fabric Jupiter. See the following blog posts:”Google’s […]
(T) One of the main reasons why the Internet has been able to sustain ever-growing traffic in its infancy is because of its famous TCP network congestion-avoidance algorithm. The TCP […]
(T) Finally, I was able to attend a talk from Stanford University Professor Nick Mckeown last month at the Silicon Valley SDN meet-up. Professor Mckeown, with Martin Casado (one of his Ph.D. students), and […]
(T) Google on its Cloud Platform Blog and at the 2015 Open Networking Summit (ONS) disclosed for the first time some details about the architecture of its latest data center switching […]
(T) I attended this week a presentation at Google from one of the network architects Bikash Koley. The topic of the presentation was about how Google manages its SDN network. […]
(T) I attended on Thursday a talk from Professor Nick Feamster from Georgia Tech at Stanford University to enable inter-domain routing for Software Defined Networks (SDN) at Internet Exchange Points […]
(T) I was interested to receive this month IEEE Computer Magazine “special edition” about Software Defined Networks (SDN). Unfortunately, the Magazine focused on describing the present efforts to standardize the […]
(T) Internet networks have been designed with two major types of protocols: data plane protocols and control plane protocols. The data plane is in charge of forwarding the packets from […]
(T) I am a strong believer that WiFi will be the most ever deployed networking technology with Ethernet. There are two reasons for that. First, is that businesses have been […]
(T) Each generation of cellular wireless networks has been characterized by new frequency bands e.g. radio waves, higher data rates, and new (but not-compatible!) transmission technology. The first generation of […]
(T) The Mobile Internet is mostly driven by the new generation of mobile devices, faster wireless networks and all the new Web services that we are using every day. There […]
(T) Between the Internet Protocol version 4 (IPv4) and version 6 (IPv6), IPv5 defined in RFC 1819 was intended for streaming traffic but has never widely been used. IPv6 was designed mainly […]
(T) Initially, Internet Protocol version 4 (IPv4) addresses were defined in IETF RFC 791 as a two-part object combining: a “network identifier” and a “host identifier”. The network identifiers are assigned by […]
(T) The Internet is running out of addresses! Each computing device connected to the Internet must have a unique worldwide Internet address. Soon, the 4.3 billion addresses that are possible […]
(T) Providing higher bandwidth applications (more) at a lower cost (with less) is the main driver for the present evolution of Ethernet. But to achieve that goal some legacy limitations […]
(T) As reported by Light Reading recently, Avici Systems became the last vendor to exit the Internet core routing market. Before Avici, Caspian Networks, Pluris, Chiaro Networks, Hyperchip, Axiowave, and […]
(T) With 100 Gb Ethernet coming soon, Ethernet, by all means, is a versatile technology. It can be deployed in many applications over many data rates. But, we need to […]
(T) Yes, a telecom start-up can still be bought for $290M like Entrisphere today by Ericsson! But it has been a while since the last time that happened. I believe […]
(T) MPLS has strongly emerged as the best technology to provide initially IP VPNs also called Layer 3 VPNs and now PWS (Pseudo Wires Services) and VPLS (Virtual Private LAN […]
(T) Organizations have been demanding virtual private networks (VPNs) instead of costly leased lines from their service providers and, Ethernet and IP services instead of DS1 and DS3 services. MPLS […]
(T) At SuperComm 2005 in Chicago, most vendors of optical CPE and transport products have now adopted the new Ethernet over SONET/SDH (EoS) family of protocols. The first EoS chips […]
(T) At the 2005 MPLS World Congress in Paris, an evolution of GMPLS called GELS was announced to provide a control plane to Ethernet switching. The idea is quite interesting […]
