Update: LISP solves the problem from client to server, IE Ingress Path Optimization. FHRP solves the problem from server to client, IE Egress Path Optimization. You can check out Egress Path Optimization here.
We recently published a Data Center Interconnect -- DCI- related document on cisco.com and I wanted to get it in front of you. Locator/Identifier Separator Protoc0l -- LISP -- provides the path optimization technology to forward transactions via the most direct path, ultimately meaning better application performance. The link for the LISP Virtual Machine Mobility paper is below.
As a side note, LISP can be used many other ways and here’s a pointer to one of our LISP pages.
For our purposes in DCI, we use LISP for path optimization and we can see here why the need arises. The box on the left shows an existing transaction that looks pretty direct. The middle box shows the workload is now in a new data center but the transaction is suboptimal, it still goes through the firsts data center. The box on the right shows the desired path, the direct path from user to workload withouth going through the first data center. It’s pretty easy to see the need here for path optimization and the desire to have the direct path to the new data center location as shown on the far right box.

Historically, enterprise customers have had a mixture of deployment goals and starting points for the implementation of IPv6. These starting points very often boil down to the following:
- Core to edge
- Edge to core
- Internet Edge-only

Last month the VCE Company, the joint venture between Cisco and EMC (with investments from VMware and Intel) that makes the Vblock infrastructure platforms, released a report on Cisco’s virtual services validating their suitability on the Vblock platform. The 40 page technical report covers both Cisco’s Virtual Security Gateway (VSG) firewall, and our Virtual Wide Area Application Services (vWAAS) WAN optimization solution. Both Cisco products run as virtual machines on a VMware hypervisor and the Nexus 1000V virtual switch on an application server, or in the case of VSG, on a Nexus 1010 services appliance. Read More »

We kick off the new year with our SuperFans of the Year and a new photo-sharing program!
It’s been over a year since we launched the SuperFan program on the Cisco Corporate Facebook page and with much success – from the level of submissions and engagement from our fans, to the recognition and coverage on various social media blog outlets. To kick off the New Year, we are bestowing the inaugural Cisco SuperFan of the Year award to Dimitar Krstevski and Sandee Weiner! They were chosen based on their level of engagement with the Cisco Facebook page and votes from the community. Big congrats and thank you!
Given the success of the SuperFan program, we are offering our fans another way to engage with us with the launch of our new photo sharing program titled, “Where in the World Do You Take Cisco?” We want to spotlight our fans and their experiences with Cisco products, technologies and the brand. Submit YOUR photos that capture everywhere and anywhere you take Cisco! Along with your photo, we also ask that you include a written description in 100 words or less that helps narrate the story behind your photo or image. Need help uploading your photos? Take a look at the Flickr Group FAQ page.
The program launches TODAY so start submitting your photos! For more information on “Where in the World Do You Take Cisco?” check out the program guidelines as well as the terms and conditions. You can also check out all of the submitted photos on our Cisco Facebook Flickr Tab. Looking forward to seeing your photos!!
