Your company has 3 sites, each with a dedicated border router, R1, R2 and R3.
Site-1 (R1) and Site-2 (R2) have their own internet uplinks, but Site-3 (R3) connects to internet via R2. A GRE tunnel is built between R2 and R3 and applied an MTU of 1440, due to some constraints in the transit network between them. You notice that traffic between same pair of devices works for TCP 1001 but fails for TCP 1002. What's wrong ?
In this article we are going to see two features that improve the load-balancing in the MLPS Core. Why? In the networking when dealing with redundancy of links or paths we are facing the polarization issue. This problem happens when one of the link is congested. Let’s take the example of LAGs, if the hashing […]

The Internet has a trust problem. With the recent revelations of government surveillance, traffic interception and modification, compromised products, and suspect algorithms, we have serious problems. Greg and Ethan spoke to this briefly on Show 175 regarding the pwning of several firewall products by the NSA, but the issue goes much further than just compromised […]

A couple of times in the past month I’ve been asked where a SSL VPN appliance should be deployed in relation to the firewall. In both cases it was relating to the Juniper Secure Access / MAG platform, but best practice should apply equally to any IPSEC or SSL VPN platform, so I thought it […]

Tunneling is the Duct Tape of Networking..It is interesting to realize that a big chunk of network features in Data Center, Service Providers and Enterprises use tunneling in one form or another..It would be fun to imagine a “world” without tunnels! Most known MPLS applications are tunneling techniques, for instance in a VPLS/L3VPN Scenario the […]

Well by the time I get around to clicking “Publish” on this post it will no longer be a secret, and you don’t know how hard its been for me not to talk about this in overly public forums.
As some of you may have heard, after five months of interviews and immigration paperwork, I have accepted a new role with Juniper Networks as a Sr Data Center* Technical Marketing Engineer. This role will see me move to the San Francisco Bay Area in the next week or so, and be based directly out of the Sunnyvale office for at least the next two years.
This new role is actually quite exciting to me (and a little bit scary) because it takes all of the knowledge and skills I have gained over the last 15 years as a consultant and then makes use them in a different way. Instead of building solutions to individual customer requirements, I will be working with the Solutions Team to help promote solutions that are universal and can scale with user need. I will be working on creating white papers, design guides and helping position Juniper Data Center their solutions.
