Cloud Ethernet Forum – Because Ethernet needs to look like Frame Relay

Where do you want Ethernet ? Everywhere apparently.

I’m at a conference about “Cloud Ethernet Forum” and subsidiary operation of the Metro Ethernet Forum that seems to want to invent a new Ethernet. The fundamental premise of the is that customers need/want/demand/must have more Ethernet in the WAN.

Why ? Because Ethernet is better for data centre managers.

Response: Reinventing storage – Ethernet über alles! | Speaking of Clouds

Holy schmoly, someone in the storage industry did something new. Geoff Arnold from Speaking in Clouds writes: Yesterday Seagate introduced its Kinetic Open Storage Platform, and I’m simply blown away by it. It’s a truly elegant design, “as simple as possible, but no simpler”. The physical interconnect to the disk drive is now Ethernet. The interface […]

Response: IEEE 400 Gb/s Ethernet Study Group

Surprising. The IEEE are just starting on 400 GbE.  Given that the 40Gb and 100GbE standards took seven years to complete this is lousy delivery from the standards body that is fundamental to networking. The current research indicates that 100GbE will be widely deployed by 2017. Starting 400GbE now is at least three years too […]

I’ve been very busy lately with several large analyst/research writing projects so less links than usual this week. It will be sometime before I return to a more regular blogging schedule. You should check out Packet Pushers in the next few days where we will be launching a new feature – we are writing our own […]

Nexus 5500 Packet Forwarding – Cut Through or Store & Forward

large_photo_nexus_5000

Was reading through some documentation as noticed that the Nexus 5500 series has some unusual behaviours for Store and Forward. I made myself notes about the functional modes. Cut-Through vs Store and Forward In cut-through mode of operation a switch will start transmitting a frame before the frame has been completely received and this is the […]

Tech Notes: Juniper QFabric – A Perspective on Scaling Up

qfabric-depth-3.jpg

Juniper QFabric is a new approach to Ethernet Switch Fabrics. When it was announced last year,it was noted that the underlying physical design is a completely different approach to building Switch Fabrics. Here I’m taking a loosely research based approach to understand how Juniper QFabric is different from all other approaches to the problem, and also a look at some of the challenges ahead.
