Summary:

This article describes the IPv6 performance and difference between IPv4 and IPv6 in the aspect of connection losses. I chose this article because it describe in details about IPv6 performance in different cases with respect to IPv4. Internet protocol is used for sending packets to the network. IPv4 is currently used and it is so good at a level, but IPv6 provide many features better than IPv4. 

In the article, IPv6 is a protocol that is more reliable over IPv4. Reliability is the first thing in the network that means data should be reached to destination. Second is the round trip time. Routing of a packet is a main role in the time taken by any packet in the network.  If any packet has less header than it will take less time and it is also depending on the fragmentation also.

In addition, measurement of performance of IPv6 is based on the data collected from nodes. There is a measure point to measure performance of a protocol that is connection failure. IPv6 has less connection failure comparative to IPv4.

Summary:

This article is described about Software-Defined Networking (SDN) architecture. I chose this source because it provides information about SDN as well as about its connectivity with OpenFlow.

SDN is used to handle traffic in the network by using control plane. Network operating system is behaving like control plane. Administrator is controlling traffic with help of OpenFlow protocol.

OpenFlow protocol gathered information from different devices and according to that manage traffic with the help of softwares.   

SDN is divides the flow of data and control functions of network devices, such as switch, hub, routers, Layer -3 switches, and packet switches with an application programming interfaces (referred as API’s) between the different networks. This is used in huge enterprise networks for controlling both data and control functions.

Data flow is increasing day by day so managing all these things use Server virtualization. It makes possible to partition a single system into multiple, autonomous systems. It is a central system in dealing with big data applications and in implementing cloud services. SDN architecture has a central controller, which perform many difficult functions, including security attacks, routing algorithms, network policy declaration, and naming.DN domains provide scalability, privacy and incremental deployment. The SDN controllers implemented in different ways, first it is require an identical logical switch function and second, it needs a safe and a standard protocol between network devices and SDN controller.

I found this article useful for learning of SDN architecture and networking fundamentals for future use.
