SPR

   240/4 Compatible Networking Switches

 

This section consists of three lists:

 

    A.    240/4 compatible Router/Switch OSs:

 

    This list presents product series built on respective OSs that are identified as 240/4 compatible. These are the primary candidates from the existing Internet facility for providing SPR services. Since EzIP operates with static 240/4 addresses, while existing facility operates with ordinary IPv4 addresses in dynamic manner, SPRs can form an overlay network utilizing the same facility without interfering the current operations, as long as there is sufficient processing capacity available. Some of these switches may require a short activation procedure to use 240/4. This is the most economical approach to deploy SPRs.

 

B.    Network Switches with 240/4 Enabled: 

 

    For situations where the above approach is not practical (no qualified equipment, existing facility already fully utilized or new installation), fresh devices should be used. In such cases, products in this category are recommended, because they are factory enabled with 240/4 capability, making installation straightforward.    

 

 

 

C.    OpenWrt based Network Switches:: 

 

    The products listed in this subsection are good prospects to upgrade if available, due to strong OpenWrt community support, and are more economical than full-fledged Routers that are overqualified for the SPR operation.

 

    Note that the list here is restricted to,

    

    "Switches with 20 or more Ethernet ports, each at 1Gbps or higher speed".

 

    These are capable enough to build the EzIP network fabric. There are similar Swtiches on OpenWrt ToH that are smaller, e.g., as few as only 8 ports. They may be used for limited extend applications, such as temporary filling configuration gaps or setting up a small network for experiments and demos.

 

    For specific instruction, search the full OpenWrt ToH by Brand Name and Model Number, then follow the procedures for flashing the memory of a specific device with OpenWrt firmware.
