Controlling Congestion when Surfing the Internet
(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 […]
Taking Programmability Down to the Wire
(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 […]
Google’s Data Center Switching Fabric
(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 […]
How Google Manages its SDN Network
(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. […]
Software Defined Internet Exchange (SDX)
(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 […]
Let’s not Kill Software Defined Networks with Standards but Let it Grow with Open Source Software
(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 […]
Providing Large Scale Cloud Services by Virtualizing Network Services over Software Defined Networks
(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 […]
The Race to Faster Data Rates WiFi Moving Soon Beyond 1 Gbps
(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 […]
Wireless for Dummies 4G LTE EPC and IMS
(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 […]
Starent Aruba and Riverbed: the New Competitors to Cisco Systems
(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 […]
Migrating to an IPv6 Internet
(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 […]
Preserving Internet IPv4 Addresses
(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 […]
The Internet Running Out of Addresses in 2011
(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 […]
NextGen Carrier Ethernet
(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 […]
The End of Infrastructure Start-Ups
(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 […]
The Versatility of Ethernet
(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 […]
A New Telecom Venture Can Still Be Bought
(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 […]
MPLS PW VPLS and IP VPNs Services
(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 […]
MPLS Label Switching Fundamentals
(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 […]
GFP VCAT LCAS Giving A New Life to SONET
(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 […]
Replacing the Spanning Tree with GELS
(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 […]
