Abstract: Methods and systems are provided for processing a received packet based on associated state information. A packet processor of a network device receives a packet from a network. The received packet is classified as belonging to at least one respective identified flow from among a plurality of identified flows. For a respective received packet that belongs to an identified flow a current state value for the identified flow is ascertained based on a state table. The current state value is assigned to the respective received packet based on the current state value using the state table for the identified flow. A packet processing operation is subsequently performed on the respective received packet based in part on the state value of the identified flow to which the respective packet belongs.

Abstract: An infusion pump includes inlet and outlet valves and a squeezing element configured to squeeze a fluid line coupled to the infusion pump. A method includes at least one round of valve operation check prior to initiation of a delivery session of fluid to a subject, and subsequently, after an intake phase and before a delivery phase of at least one infusion pump cycle, determining for the at least one pump cycle, an absolute amount of air in the fluid line. The valve operation check and the determining of the amount of air each include: (A) closing the inlet valve to confine a section of the fluid line between the inlet and outlet valves; (B) squeezing the confined section; (C) measuring the pressure within the confined section; and (D) subsequently, relieving the pressure in the confined section. Other applications are also described.
