Internets of Interest:1 Apr 11

Collection of useful, relevant or inane places on the the Internets for 1 Apr 11:

  • Narrowcom To Unveil Wi-FiBASE-T – Network Computing -

    But Wi-Fi performance can leave much to be desired. Throughput is hampered by backwards compatibility, microwave popcorn, and security cameras, and most seventh graders can accurately pitch a note out of range of the average access point. Plus, only anointed wizards possessing dark knowledge have the ability to put together a successful wireless LAN. The market is ripe for some new thinking, but multiple spatial connections, a switch to 5 GHz, and the removal of load-bearing walls haven’t been successful 

    Awesome.

  • Gmail Motion BETA -

    Easy to learn
    Simple and intuitive gestures
    Improved productivity

    Amazing technology.

  • Storage Vendors Announce FCoTR and VATRI Support ñ Gestalt IT -

    Data Domani, a division of ETC, added, ìwe are implementing FCoTR and VATRI support into our line of storage arrays. †This will enhance the ability for vSphere 5 to do backups, restores and replication of the backups. †The FlexIO modules for FCoTR and the VATRI plugin will be released in May at our ETCWorld conference, with parts shipping in June of 2012.î 

    FCoTR continues to grow. I’m getting that feeling the FCoE has come to the game too late and with the wrong approach. Now the VMware is rumoured to offer support, well the game might be over.

  • YouTube – Aerohive…Now with Rainbows – Aerohive are doing a better job of communicating their controllerless networking architecture here with the liberal use of rainbows. Interesting approach to a difficult topic now that Openflow is promoting controller based networking in new ways.
  • RFC 6214 – Adaptation of RFC 1149 for IPv6 -

    RFC 1149 does not specify the use of any link layer tag such as an
    Ethertype or, worse, an OSI Link Layer or SNAP header [RFC1042].
    Indeed, header snaps are known to worsen the quality of service
    provided by RFC 1149 carriers. In the interests of efficiency and to
    avoid excessive energy consumption while packets are in flight
    through the network, no such link layer tag is required for IPv6
    packets either. 

    Some fine work here to ensure that RFC1149 is updated for IPv6. The gold standard reference for tenders to check vendor compliance is now IPv6 ready.

  • RFC 6217 – Regional Broadcast Using an Atmospheric Link Layer -

    Broadcasting is a technology that has been largely discarded in favor
    of technologies like multicast. This document builds on RFC 919 and
    describes a more efficient routing mechanism for broadcast packets
    destined for multiple Local Area Networks (LANs) or Metropolitan Area
    Networks (MANs) using an alternative link layer. It significantly
    reduces congestion on network equipment and does not require
    additional physical infrastructure investment. 

    Probably shaking up the the data centre fabric market. This RFC bears close monitoring.

  • News ñ Cisco Announces EOL Schedule for 6500s | Aaron’s Worthless Words -

    This is a surprise, but Cisco has announced the end of life of the 6500 switches that we all know and love. †Usually Cisco gives a platform a few more years after they decide to retire it, but the schedule only gives the 6500s one more year of service. †Iím sure this goes back the success and recent expansion of the Nexus line of switches. 

    Long overdue in my opinion, it’s time to move on.

  • iRules: Cold Dead Hands -

    The best known product for traffic manipulation is likely F5?s legendary iRules, but other vendors have similar capability such as A10?s aFlex. Essentially, this puts an application development platform. Typically this is done with a standard programming language, such as a modified TCL for iRules and aFlex. 

    Good article (in fact, a good site) about load balancing. Here Tony takls about application level load balancing and data modification.

  • Cisco Catalyst 6500 Series ASA Services Module – Products & Services – Cisco Systems -

    The Cisco Catalyst 6500 Series ASA Services Module is a high-speed, integrated network security module for Cisco Catalyst 6500 Series Switches. Delivering industry-leading firewall data rates, this module provides exceptional scalability to meet the needs of today’s dynamic organizations – in a single blade architecture. 

    The ASA module for the 6500 finally arrives. About two years later than expected. The question of whether it will be bought in sufficient numbers now that the C6500 is, for practical purposes, history mean that it may not last long. Cisco will kill products that do not sell enough.

  • HP IPv6 -

    HP is rolling out IPv6 support in stages with the goal of ensuring a smooth transition and deployment where IPv6-updated applications can take advantage of IPv6, without breaking existing applications. 

    Scary, not much data here. Not encouraging.

  • Enhance Service Delivery with Cisco Catalyst 4500E and NAM Appliance† [Cisco NAM 2200 Series Appliances] – Cisco Systems – A NAM module for the Cisco 4500E ! At this rate, the C4500 will have more features that the C6500. And with the C6500 being put into slow mode (for the NX7K) they might exceed it at this rate.
  • Alex S

    Ad RFC 6214: there is still no support for multicasting though :-(

    I would point my attention to RFC 5984, too. Extra Sensory Perception is indeed great way to solve latency problems with networks, as it’s not dependent on underlying physical limitations (like speed of light). Some media even support negative latency with PPG (Precognitive Packet Generator).
