Abstract: Techniques for implementing intelligent hardware assisted ICMP request processing in a network device are provided. According to one embodiment, the network device can receive an ICMP request packet and write the packet to a protocol buffer configured to queue packets for processing by a management CPU. When the ICMP request packet is ready to be processed by the management CPU, a hardware-based ICMP request handler of the network device can determine whether the ICMP request packet matches any entries in an ICMP table. If the ICMP request packet does match an entry in the ICMP table, the ICMP request handler can generate an ICMP response packet for replying to the ICMP request packet, without sending the ICMP request packet to the management CPU.

Abstract: Techniques for implementing application traffic prioritization in a network device are provided. In one embodiment, the network device can determine a packet buffer threshold for a received data packet. The network device can further compare the packet buffer threshold with a current usage of a packet buffer memory that stores data for data packets to be forwarded to a processing core of the network device. If the current usage of the packet buffer memory exceeds the packet buffer threshold, the network device can perform an action on the received data packet.

Abstract: Methods of making cross sectional, functionally-graded munitions propellants exhibiting various distributions of particle concentrations and burn rate, including having a fast burning core and slower burning outer layer(s). Unlike prior art methods of preparing such munitions, propellants prepared according to our inventive method(s) may be performed substantially as a single extrusion step or as a few processing steps, without requiring the time, expense and/or difficulties that characterized familiar, laminating methods and methods which use multiple extruders. Our inventive method advantageously employs a demixing phenomenon that, prior to our inventive application and teaching, has been considered quite undesirable in the preparation of propellants where uniformity and well-mixedness have been propellant attributes widely sought after.

Abstract: A high energy propellant, comprising an oxetane thermoplastic elastomer energetic binder admixed with a high energy explosive filler. The oxetane thermoplastic elastomer energetic binder preferably comprises from about five percent to about thirty percent by weight and the high energy explosive filler comprises from about seventy percent to about ninety-five percent by weight of the composition. A preferred propellant further includes an explosive plasticizer, preferably in an amount of about four percent to about seven percent of the plasticizer by weight of the propellant. The preferred filler is selected from the group consisting of CL-20, TNAZ, RDX and mixtures thereof. The preferred plasticizer is selected from the group consisting of TNAZ, BTTN, TMETN, TEGDN, BDNPA/F, methyl NENA, ethyl NENA and mixtures thereof.

Abstract: A high energy propellant, comprising at least one oxidizer; a nitrocellul binder; an ethyl centralite stabilizer; a plasticizer; and an oxetane thermoplastic elastomer energetic binder. The oxetane thermoplastic elastomer energetic binder comprises from about zero percent to about fifteen percent by weight of the propellant. The preferred oxidizer is selected from the group consisting of CL-20, TNAZ, RDX, HMX and mixtures thereof. The oxidizer comprises from about five percent to about forth percent by weight of the propellant. The nitrocellulose binder comprises from about fifteen percent to about fifty percent by weight of the propellant and the ethyl centralite stabilizer comprises from about 0.7 percent to about 1.5 percent by weight of the propellant. The plasticizer is selected from the group consisting of TNAZ, BTTN, TMETN, TEGDN, BDNPA/F, methyl NENA, ethyl NENA and mixtures thereof. The plasticizer comprises from about five percent to about thirty-five percent by weight of the propellant.

Abstract: A method of formulating high energy explosives and propellants, including e steps of melting the explosive at a temperature just above its melting temperature, admixing and dissolving or plasticizing a binder, and extruding or casting the resultant solution into a useful form for further forming the resulting material into a munitions. The first step in this method includes the use of any high energy explosive material. Examples of these include hexanitrohexaazaisowurtzitane or CL-20, 1,3,3-trinitroazetidine or TNAZ, 2,4,6-trinitrotoluene or S-TNT, 1,3,5-trinitrobenzene or S-TNB, HMX, RDX, butane-trio-trinitrate or BTTN, trimethylolethane trinitrate or TMETN; triethylene glycol dinitrate or TEGDN, bis, 2,2-dinitro propyl acetal/bis 2,2 dinitro propyl formal or BDNPA/F, methyl nitrato ethyl nitramine or methyl NENA, ethyl NENA, mixtures thereof and the like.

Abstract: A multi-layer propellant and a method for making the same is provided, in ich the propellant has at least one slow burning formulation and at least one fast burning formulation, such that the ratio of these burning rates is at least 2:1. The propellant produces an impetus of at least 1300 Joules/gm. The preferred binder is a high energy oxetane thermoplastic elastomer. The preferred slow burning formulation employs RDX, while the preferred fast burning formulation employs CL-20. The two formulations are formed separately, such as in layers that are then fused, using the bonding strength of the binder. The shape may be any shape that is useful in munitions and may include one or many layers of each burning rate. Preferred shapes include a multi-layered propellant with one slow burning formulation on top and a bottom layer of the fast burning formulation. The layers may be formed from ribbons, discs, cones, truncated cones and partial spheres.
