Fulcrum ponders OpenFlow’s implications upon the switch market

March 25th, 2010, Glen Gibb in OpenFlow Blog

In a recent blog post (Will OpenFlow Software Unlock the Switch Market?), Gary Lee of Fulcrum Microsystems considers the implications of OpenFlow upon the switch market. The post notes that OpenFlow “breaks the software lock that some switch vendors have with their system customers”. Indeed, OpenFlow enables companies to develop controllers without developing their own hardware; controllers will interoperate with OpenFlow-enabled switches from any hardware vendor. We (the OpenFlow team at Stanford) expect that this will have a dramatic effect upon innovation as it enables companies to much more easily deploy new services within their networks.

We’re glad to see the increasing interest being shown in OpenFlow by industry, and we eagerly look forward to the availability of more OpenFlow-enabled hardware.

OpenFlow-MPLS project at Ericsson

March 1st, 2010, Guido Appenzeller in OpenFlow Blog

Over past summer Ericsson research at San Jose, CA started a project called OpenFlow-MPLS to add MPLS support to OpenFlow. The project is now complete and available via the Project’s Page on the Openflow Wiki.

The implementation includes a user space switch, a kernel space switch and NetFPGA implementation and is based on OpenFlow v0.89.

It supports MPLS by adding two tupels to standard OpenFlow tupels, which can match on up to two top of the stack MPLS labels. The rewrite action is supported in flow table for MPLS tags, but other MPLS related actions (Push, Pop, TTL and EXP bits operations) are supported via MPLS-enabled virtual ports.
