In computer networking, a unicast flood occurs when a switch receives a unicast frame and the switch does not know that the addressee is on any particular switch port. Since the switch has no information regarding which port, if any, the addressee might be reached through, it forwards the frame through all ports aside from the one through which the frame was received.
In computer networking, a media access control attack or MAC flooding is a technique employed to compromise the security of network switches.The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where it is not normally intended to go.
In the case of unknown-unicast traffic, a security issue may arise. To prevent flooding unknown-unicast traffic across the switch, it is possible to configure the network equipment to divert unknown-unicast traffic to specific trunk interfaces in order to split broadcast coming from different VLANs or to use specific trunk interfaces for ...
Most regulatory authorities in the United States that offer requirements for flood openings define two major classes of opening: [1] engineered, and non-engineered. The requirements for non-engineered openings are typically stricter, defining necessary characteristics for aspects ranging from overall size of each opening, to allowable screening or other coverage options, to number and ...
Fire blocking may also serve as bridging between framing elements, stiffening them against lateral buckling. [4] [5] Fire blocking or firestopping terminology was used interchangeably in code language from its first mention in the 1905 National Building Code (NBC), and requirements were expanded in the 1927 Uniform Building Code (UBC). Building ...
The overall effect is layers of paint-like swaths over the whole of the ceiling or wall. He can then just walk away and let it set with care taken not too leave any globs and to make sure the corners look smooth and linear. If a wall is to be smooth and the ceiling textured, typically the wall is done first, then the ceiling after the wall has set.
The average annual cost of flood insurance from the NFIP was $700 per year, but under the new system policyholders pay on average $800. Risk Rating 2.0 considers a host of variables that weren’t ...
The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the basement. The Federal Emergency Management Agency (FEMA) recommends basement waterproofing with a water alarm and "battery-operated backup pump" as a preventive measure against the high ...
