The Future of Software-Defined Networking

Listen to the Podcast

August 27th, 2012

Rakesh Saha, Director of Product Management for Advanced Technologies at IBM System Networking and Samrat Ganguly, Chief Network Architect for NEC’s ProgrammableFlow join me to help us make sense of the fast paced evolution of Software-Defined Networking and predict its future.

Duration: 12 minutes and 26 seconds

Lippis Intro/Analysis @ : 00:10 sec

Question 1 @ 2:19 sec: Rakesh, There are a few approaches to SDN including overlay virtual networks, OpenFlow control of physical and virtual switches plus a hybrid. How do you see these implementations evolving over time?

Question 2 @ 5:10 sec: Samrat, There are a range of protocols to use for the overlay of virtual networks to tunnel through physical L2/3 networks, such as GRE, VXLAN , NVGRE, etc. How will this space evolve?

Question 3 @ 6:34 sec: Rakesh, There’s discussion in the industry about how SDN can be used to configure a converged LAN/SAN fabric. Can you talk to this?

Question 4 @ 7:58 sec: Samrat, there are multiple approaches for SDN controllers, be it in a hypervisor, an appliance, part of a cloud stack, etc. How do you see the role of the controller evolving over time?

Question 5 @ 9:17 sec: Rakesh, How do you see SDN evolving and how does programmable networking fit in?

Question 6 @ 10:52 sec: Samrat, same question. How do you see SDN evolving and how does programmable networking fit in?

Extreme Networks Offers A Broad Open Networking Initiative

Listen to the Podcast

August 20th, 2012

Merchant VP of Technology at Extreme Networks joins me to discuss Extreme’s approach to open networking including its Open Fabric, Software Defined-Networking or SDN initiative plus network programmability.

Duration: 12 minutes 20 seconds

Lippis Intro/Analysis Starts @ : 00:10 sec

Question 1 @ 1:58 sec: Shehzad. lets first start with Extreme’s view of SDN market drivers. What are your customers asking for?

Question 2 @ 3:52 sec: Shehzad, Extreme describes an SDN architecture with four layers. Let’s describe that to the audience as its central to the re-distribution of network responsibilities and functions.

Question 3 @ 6:51 sec: Shehzad, Extreme’s initiative consist of four components: 1) Open programmability of networking, 2) SDN/OpenFlow & Multiple controller support, 3) support for OpenStack and quantum and 4) all of the above built on top of an open fabric. Can you talk to each initiative and how they are additive in value?

Question 4 @ 10:39 sec: What does Extreme’s Open fabric SDN approach bring to IT business leaders and how can they take advantage of it?

Lippis Report 197: Cisco’s Unified Fabric for Physical, Virtual and Cloud Environments

August 14th, 2012

Over the past several years, the term “fabric” has been used to describe a weave of computing, storage and networking that make up the foundation of data center infrastructure. Many networking firms use the term “fabric” to describe converged networking and storage. But today’s data centers are built with a combination of physical, virtual and cloud networking elements that need to interoperate and span multiple data centers. A modern fabric needs to incorporate all of these forms of networking consistently to deliver flexibility through a wide range of design options. Cisco Systems has one of the most expansive fabric definitions that is backed up by over 36,000 customers who deployed NX-OS. Cisco modifies the term “fabric” with the word “unified” to describe a functionally-rich fabric, yet control is simplified through integrated management. In this Lippis Report Research Note, we review Cisco’s Unified Fabric from business driver, architectural structure and outcome point of views.

The Changing Face of Data Centre Networks

August 14th, 2012

By Quocirca

UK analyst firm, Quocirca, describes why fast and intelligent system networks, such as IBM’s, are of critical importance for the smarter data centre. As networking technology has standardised around Ethernet, the perception has grown that it has also commoditised. However, as technical architectures evolve to keep pace with the impact of virtualisation, cloud computing and high-performance workloads, the needs around networking are also changing. This is driving data centre operators to understand how recent performance advances and standards-based innovations in system networking infrastructures can meet the performance, scalability and agility requirements of today’s data centres.

Cisco on VXLAN For Logically Isolating Virtual Subnets At Scale

Listen to the Podcast

August 6th, 2012

Scalability issues have overcome what VLANs were designed to provide. In multi-tenant cloud computing environments with each tenant having many applications many of which require their own logical network segments, the 4k limit of VLANs does not scale. And as cloud networks grow beyond data centers, logically isolated subnets have to be expanded to include geographic scale. Challenges include application mobility over very large resource pools that cover multiple sites, while ensuring the same consistency and logical network policy constraints. Enter VXLAN, jointly announced last summer by industry heavy-weights Cisco Systems, VMware, Red Hat, Arista and others. Han Yang Senior Product Manager at Cisco Systems joins me to discuss VXLAN in virtual networking and the challenge to logically isolate virtual subnets in highly scalable, multi-tenant data centers.
