A technique that allows for more data. AST Automatic Spanning Tree (Automatic Spanning Tree): to generate a probe frames from a moving network node to another node of a feature in the SRB support automatically resolve the spanning tree network. The AST is based on the IEEE 802.1 standard. See IEEE802.1 and SRB . Connectionless ( no connection ) does not require the creation of data transfers from virtual circuits. It has no overhead, try its best ( Such as OSPF and BGP4) supported by a method based on ignoring TP concept of address classes, allowing route summarization and routers can be combined to minimize the need for routing the main transmit routing information in the router VLSM . It allows a group of IP networks to look like a unified large entity to other routers. In CIDR , IP addresses and their subnet masks are written A technique that differs from ordinary TDM in that time slots are allocated when necessary rather than pre-assigned to certain transmitters. Compare FDM , statistical multiplexing, and TDM .
