Industrial Wireless Router Table Variables

  Industrial Wireless Router Table Variables

  Table variables are more important, such as routing table, port table, address table, TCP connection table, etc., the most important of which is the routing table and port table. The routing table has more than 1M routing entries in the limit case. Therefore, it is necessary to optimize the design of the routing table and its accesses. However, due to the large scale of the routing table, the impact of the access routing table on the forwarding of the whole industrial router So there are still a lot of problems when the network management agent accesses the routing table. A typical design is usually targeted by:

  1. Mutual access is required for read / write access to the routing table.

  2. The management agent writes to the routing table and writes to other routing protocols to share the same interface.

  3. The read operation of the routing table does not guarantee that at any time exactly matches the topology of the actual industrial TD-LTE router table.

  The amount of data in the port table is much less than the routing table, but it is more complicated to handle because of the more tasks involved. A typical system supports the port tables described by SMIv1 and SMIv2, which are temporally mapped to the same physical address space. You must solve the problem of task synchronization.
