Starting at 9:00am US EST (UTC-5) today, January 23, the State of the Net 2017 conference will stream live out of Washington, DC. This annual event brings together politicians, U.S. Congressional staff and other policy makers to discuss the current state of Internet policy, particularly as it relates to U.S. positions and policies. Given the new U.S. President, this year's event should be of special interest. You can watch live at:
We will have two Internet Society staff participating:
If your company is embarking on an IPv6 migration, here are some basics to help you get you started.
For the following scenario, subnets are stretched across multiple locations using a Layer 2 DCI solution. There are several use cases that require LAN extension between multiple sites, such as Live migration, Health-check probing for HA cluster (heartbeat), Operational Cost containment such as migration of Mainframes, etc. It is assumed that due to long distances between sites, the network services are duplicated and active on each of the sites. This option allows the use of local network services such as default gateways, load balancer’s and security engines distributed across each location, helps reduce server to server communication latency (East-West work flows).
Traditionally, an IP address uses a unique identifier assigned to a specific network entity such as physical system, virtual machine or firewall, default gateway, etc. The routed WAN uses the identifier to also determine the network entity’s location in the IP subnet. When a Virtual Machine migrates from one data center to another, the traditional IP address schema retains its original unique identifier and location, although the physical location has actually changed. As a result, the extended VLAN must share the same subnet so that the TCP/IP parameters of the VM remain the same from site Continue reading
One of the quotes I found in the Mythical Man-Month came from the pre-GPS days: “never go to sea with two chronometers, take one or three”, and it’s amazing the networking industry (and a few others) never got the message.
