|Ensuring Interoperability for Open Networking Systems||Christina Dube, Daniel Gray and David Woolf||
Open Networking has created new opportunities and new challenges for Data Center designers and implementers. Many customers are used to deploying monolithic solutions from a single integrator. When implementing Open Networking solutions from multiple providers, a few key questions arise: Will it all work? Are there common interfaces I can use to monitoring and control the hardware? How do Data Center designers and implementers ensure that the components they’ve chosen will be interoperable? Will the Open Networking Solution work as well as or better than a traditional monolithic solution?

|An Efficient Method for Stream Semantics over RDMA||P. MacArthur and R. Russell||
Most network applications today are written to use TCP/IP via sockets. Remote Direct Memory Access (RDMA) is gaining popularity because its zero-copy, kernel-bypass features provide a high throughput, low latency reliable transport. Unlike TCP, which is a stream-oriented protocol, RDMA is a message-oriented protocol, and the OFA verbs library for writing RDMA application programs is more complex than the TCP sockets interface. UNH EXS is one of several libraries designed to give applications more convenient, high-level access to RDMA features. Recent work has shown that RDMA is viable both in the data center and over distance.
One potential bottleneck in libraries that use RDMA is the requirement to wait for message advertisements in order to send large zero-copy messages. By sending messages first to an internal, hidden buffer and copying the message later, latency can be reduced at the expense of higher CPU usage at the receiver. This paper presents a communication algorithm that has been implemented in the UNH EXS stream-oriented mode to allow dynamic switching between sending transfers directly to user memory and sending transfers indirectly via an internal, hidden buffer depending on the state of the sender and receiver. Based on preliminary results, we see that this algorithm performs well under a variety of application requirements.

|Further Testing of TRILL (TRansparent Interconnection of Lots of Links)||Christina Dube||
The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted its second TRansparent Interconnection of Lots of Links (TRILL) Interoperability Test Event the week of May 20 - May 24, 2013 at its 32,000+ square-foot facility in Durham, New Hampshire. The test event brought together implementers of TRILL as well as test equipment manufacturers that support TRILL. The purpose of the test event was to gain a perspective on the current status of TRILL implementation and interoperability. Participants included Extreme Networks, Hewlett-Packard Networking, Huawei Technologies, and Ixia.
