    13 The Brocade equipment has been received and deployed to the field, along with the Cisco optronics providing 10GE connectivity between them.  As of this writing, the Brocade beta code providing OpenFlow support contains a significant bug rendering it effectively incapable of interoperating with non-OpenFlow-enabled Layer-2 networks such as NLR’s FrameNet and CENIC’s HPR-L2.  As a result, although COTN is extant as a stand-alone OpenFlow network, no useful research can be conducted on it in its present state.

    34 Significant difficulties have been encountered with the Brocade pre-beta and beta OpenFlow code.  Initial efforts to facilitate a demo for GEC14 were hindered by the lack of functionality in the pre-beta code to rewrite source IP addresses.  Subsequently, a major bug was found in the beta code in which VLAN tags were inappropriately stripped, rendering COTN incapable of interoperating with non-OpenFlow networks such as NLR’s FrameNet and CENIC’s HPR-L2, both essential access mechanisms for the planned use of COTN. Brocade anticipates a bug fix for the latter issue in August 2012.
