  • Publication number: 20090129407
    Abstract: Systems, methods, and devices for consolidating network packetized data are disclosed. Data packets are received by a consolidator. Common content and unique attributes of the packets are identified. A consolidated packet is created and the consolidated packet is transmitted in response to a condition.

  • Patent number: 5818828
    Abstract: In a wireless frequency hopping communication system, a protocol, which does not employ carrier sense or collision detect, is provided for allocating bandwidth fairly and efficiently under varying load conditions, wherein a node is permitted random access to the medium bandwidth under light loading conditions and wherein under higher loading conditions a time/bandwidth allocation is made with a portion of the allocation dedicated to inband backhaul tasks by introducing a form of polling, the size of the reserved time/bandwidth allocation being selected based on traffic pattern. Under such heavy load conditions, non-slave traffic is allocated bandwidth in slots as pseudo-slave packets to guarantee a share of the bandwidth. Depending on the activity of the population of packets, including responsiveness and trend of responsiveness, the relative size of the slots is determined.

  • Patent number: 5570084
    Abstract: In a packet communication system, loose source routing is employed to permit communication over networks of disparate types, including geographic and path-unaware types. No information resides on a wired access point (WAP). All of the intelligence of the system resides in Name Servers, which provide opaque addresses that end nodes (radios) in a wireless cloud can use to send packets to other end nodes (radios) in other wireless clouds. (A cloud is the set of radios serviced by a particular WAP.) According to the invention, the method employs an ordered list called a path and the network address of a packet consists of such an ordered list of addresses with a "marker" that flags the current destination of the packet and a "direction bit" that tells which direction on the list the next destination is. Each address in the path is type-length-value (TLV) encoded.
