Abstract: Signaling to control transmit/receive mode transitions of a serial half-duplex transceiver coupled externally to an integrated circuit is provided by the integrated circuit separately from a host processor of the integrated circuit with which the transceiver communicates. This can avoid slow transceiver turn-around times that may be associated with host processor control of the mode transitions.

Abstract: A fluid filter formed of microbially-produced cellulose, preferably formed into a web of cellulose fibers in artificial culture of the microbes, then removed from the culture and shaped into a filter. The shaping may include a compression step and may also include an embossing step. Methods of culturing and forming the filter are also disclosed.

Abstract: In general, techniques are described for performing a mass withdrawal of media access control (MAC) addresses using a reduced number of route withdrawal messages within a singly-homed segment of an Ethernet Virtual Private Network (EVPN). The techniques may include determining a segment identifier of the segment and sending a route advertisement to advertise a route for the segment identifier to a provider edge network device. The techniques may include sending a route advertisement to advertise one or more media access control (MAC) routes for the layer two segment. The techniques may also include, responsive to determining a link failure between a first provider edge network device and a customer edge network device, sending a withdrawal message to the second provider edge network device for the route associated with the segment identifier to withdraw all of the plurality of MAC routes at the second provider edge network device.
