The Next Evolution of Cisco’s Nexus 1000V Virtual Switch to be Featured at VMworld”

…Firewall, VSG zone-based virtual firewall, vWAAS WAN optimization, the Cloud Services Router (CSR) 1000V, and Cisco Prime Network Analysis Module (NAM) and built on Cisco’s advanced service insertion and chaining technology, vPath. Feature and management consistency with Cisco Nexus data center switches for seamless integration with the physical infrastructure. A true management control plane (with the Nexus 1000V virtual supervisor module) that…

New Nexus 1000V Virtual Switch 1.5.2 Release Now Available

…ce chaining between virtual services. I wrote a blog post a couple of weeks ago about the importance of vPath in inserting virtual services into data center networks, and now we also have a great new white paper available on vPath service insertion technology. The most important enhancement in vPath 2.0 is that you can now insert multiple services in the path between the source and destination addresses in your virtual network.  For example, you…

VMware’s SDN Strategy is No Threat to Cisco, says Mike Fratto

…ilar to the IETF’s TRILL, which lets network admins create multiple loop-free paths through networks. Cisco also has the Nexus 1000V, which has replaced WMware’s vSwitch. Cisco has continually added features like vPath to the 1000V, which can be used to add Layer 4-7 services like load balancing and firewalls its virtual switch. Cisco is also supporting VXLAN, which enables overlay networks similar to Nicira’s STT. Finally, the…

vPath: The Secret Sauce to Enabling Virtual Network Services

…uite a popular post, so I’m following up this week on another fundamental component of Nexus 1000V-based virtual networks, vPath, the secret sauce that allows us to deploy virtual network services in the data center. What is vPath? Well, if VXLANs can set up secure tunnels over a shared, multi-tenant virtual network, vPath is a feature of the Nexus 1000V virtual switch that can redirect traffic to virtual application services before the switch…

Some Afterthoughts on Open Network Environment, SDN and Overlay Networks

…i-vendor VXLAN tunneling technology. The other point that I think was frequently overlooked in all the hoopla was the importance of Layer 4-7 virtual services to the virtual overlay story, and specifically the role of vPath. vPath is a component of the Nexus 1000V virtual switch that enables the integration of virtual service nodes into virtual overlays. vPath is critical to inserting services such as security, WAN optimization or load balancing…
