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.
Hey folks--this is the second of three posts looking a little more closely at VXLAN. If you missed the first post, you can find it here. In this installment we are going to look at the some of the other options out there. Two of the most common questions we see are ”why do I need yet another protocol?” and “can I now get rid of X?” This should help you answer these questions.So, let’s dig in… Read More »
What if your mobile device allowed you the freedom to seamlessly roam across any network in the world, regardless of location or operator and with all the attributes you would expect, security or privacy… With LISPmob, we may have gotten a giant step closer as we open sourced a network stack for network mobility on Linux platforms, an implementation of basic LISP mobile node functionalities.
With the opening of the new Cisco Datacenter in RTP, I thought it would be cool to reach out to a few of the guys responsible for the design and ask them a few questions. So, I got together with Jag Kahlon (Cisco IT Architect) and John Banner (Cisco IT Network Engineer) for a quick chat.
Me: What were the primary objectives for the new datacenter?
