Introducing OpFlex – A new standards-based protocol for Application Centric Infrastructure

Continuing on its tradition of contributing and committing to open source and open standards over the last 25 years, today Cisco announced “OpFlex” – a new open standards-based protocol for Application Centric Infrastructure that has been submitted into the IETF standardization process. We believe this will accelerate multi-vendor innovation in data center and cloud networks to drive operational simplicity, lower costs and increased agility.

Why is this required?

Traditional SDN models today function on the basis of an imperative control model with a centralized controller and distributed network entities that support the lowest common denominator feature set across vendors such as bridges, ports and tunnels. As the network scales, the controller becomes a bottleneck due to the need to maintain increased state, and starts to impact performance and resiliency. Likewise, because the applications, ops and infrastructure requirements need to be translated into network configuration, it impacts agility and introduces a manual learning process, requiring app developers to describe their requirements in low-level constructs.

If we contrast that with the vision of the ACI model with the Application Policy Infrastructure Controller (APIC), ACI adopts a declarative management approach. This model abstracts applications, operations and infrastructure providing simplification and agility. By distributing complexity to the edges, it also increases better scalability, and allows for resiliency – i.e. the data forwarding can still continue to happen even if there is no controller. It further provides ease of use with self-documenting policies automatically deployed or cleaned up from devices as necessary. All of these help circumvent the issues seen in traditional SDN models.

For this declarative model to work across a multi-vendor environment, to translate and map policy definition into the infrastructure, there has hitherto been no standard protocol to do that across physical/virtual switches, routers and L4-L7 network services. This vacuum has led to the development of “OpFlex” – a new open standard recently submitted to the IETF.

Who is contributing to OpFlex?

Several industry leaders and practitioners are actively involved in the standardization process. These include Microsoft, IBM, Citrix and SunGard Availability Services, in addition to Cisco.

Is Your WLAN Ready for Unified Communications & Collaboration?

January 31, 2014 at 5:00 am PST

As Wi-Fi continues to be the primary mode of access, enterprise Unified Communication(UC) applications usage is increasing with smartphones, tablets and laptops.

Customers are asking, is there anything I can do to prioritize Jabber or Lync traffic over others or even identify how much of the traffic is really collaboration traffic vs. other types of media. The recently introduced Wireless Release 7.6 enhances the ability to classify Microsoft Lync 2013 and Jabber with Cisco WLAN Infrastructure.

In the first blog about Application Visibility and Control over Cisco WLAN, I captured what is AVC and the capabilities included in the release 7.4. In a subsequent blog, I had captured a success story about a customer who benefited from the reliability by deprioritizing scavenger level applications as well as captured highlights of the enhancements in release 7.5. This blog captures how the release 7.6 allows popular collaboration applications to be accurately classified and prioritized as well as provides a teaser to some of the innovations that can be expected in the future.

What exact capabilities AireOS 7.6 provide ?

The protocol pack 6.3 introduced in AireOS 7.6 allows you to identify and prioritize not just Jabber but also sub-classify Cisco Jabber Audio, Cisco Jabber IM and Cisco Jabber Video. Customers may want to prioritize the Cisco Jabber Audio as the highest priority while the others may be lower priority. Similarly you can classify not just Microsoft Lync but also Microsoft Lync Audio, rtcp and Microsoft Lync Video and thereby prioritize them separately. Read More »
