Management Information Base The deﬁnitions for a particular set of data variables, with those deﬁnitions following the SMI speciﬁcations. See also SMI.man-in-the-middle attack A characterization of a network attack in which packets ﬂow to the attacker, and then out to the true recipient. As a result, the user continues to send data, increasing the chance that the attacker learns more and better

Join/Prune message Sent by a PIM router to its upstream router to either request that the upstream router forward the group trafﬁc or stop forwarding the group trafﬁc that is currently being forwarded. If a PIM router wants to start receiving the group trafﬁc, it lists the group address under the Join ﬁeld. If it wants the upstream router to stop forwarding the group trafﬁc, it lists the group

half duplex Ethernet feature in which a NIC or Ethernet port can only transmit or receive at the same instant in time, but not both. Half duplex is required when a possibility of collisions exists.hardware queue A small FIFO queue associated with each router’s physical interface, for the purpose of making packets available to the interface hardware, removing the need for a CPU interrupt to start

Fast Secure Roaming Enables a wireless client to securely roam between access points in the same subnet or between subnets with access point handoff times within 50 ms.fast switching An optimized Layer 3 forwarding path through a router. Fast switching optimizes routing table lookup by creating a special, easily searched table of known ﬂows between hosts.FD See feasible distance.feasibility
