  Dynamic address assignment in an arbitrarily connected network - Patent 5745699
The AARP probe packet 500 illustrated in FIG.
The AARP probe packets are broadcast at step 404 to and received by all nodes having the connectivity radius of zero with the acquiring node (those nodes which are all directly connected to the node desiring to acquire the address as illustrated in FIG.
As the packet is received and re-transmitted by each subsequent node in the chain of nodes during the AARP forward probe process, the radius remaining field 559 is decremented by each node which receives and rebroadcasts the packet.

 AppleTalk - Wikipedia, the free encyclopedia
The AppleTalk address resolution protocol (AARP) allowed AppleTalk hosts to automatically generate their own network addresses, and the Name Binding Protocol (NBP) was essentially a dynamic Domain Name System (DNS) system which mapped network addresses to user-readable names.
AARP resolves AppleTalk addresses to physical layer, usually MAC, addresses.
Exactly-once mode was essential for operations which were not idempotent; in this mode, the responder kept a copy of the response buffers in memory until successful receipt of a release packet from the requestor, or until a timeout elapsed.

 Network device location using multicast - Patent 5282270
The AARP probe packet 640 is used to determine whether the address is currently being used by another node on the network.
In an AARP response packet 620, field 632 is used to transmit the protocol address for the node with the hardware address transmitted by an AARP request packet 600 or an AARP probe packet 640.
Packet 1200 comprises a first byte divided into a function field 1201 and a tuple count 1202 wherein the function field comprises the four most significant bits of the byte, and the tuple count 1202 comprises the four least significant bits of the byte.

 Local area network device startup process - United States Patent 5,150,464
Therefore, when a router obtains a packet addressed to a network number and node ID that is not directly accessible through one of its ports, the packets is then forwarded through that port to the next IR on the path to the destination network so that the appropriate node will eventually receive the data packet.
AARP probes 640 are retransmitted approximately ten times to ensure receipt by all nodes on the LAN.
AARP probes 640 are sent by the node until the node fails to receive an AARP response 620 within a specified period of time.

packets ``dropped by kernel'' (this is the number of packets that were dropped, due to a lack of buffer space, by the packet capture mechanism in the OS on which tcpdump is running, if the OS reports that information to applications; if not, it will be reported as 0).
On subsequent packets of the conversation, the difference between the current packet's sequence number and this initial sequence number is printed.
Error codes are printed for abort packets, with the exception of Ubik beacon packets (because abort packets are used to signify a yes vote for the Ubik protocol).

 Packet - CompWisdom
Packet sockets are not subject to the input or output firewall chains.
Each packet's header will contain the proper protocols, the originating address (the IP address of your computer), the destination address (the IP address of the computer where you are sending the e-mail) and the packet number (1, 2, 3 or 4 since there are 4 packets).
A packet transferred between host and RPC consists of between 1 and 28 bytes, the first byte of the packet is always the control byte.

The next field 358 of the TLAP packet 350 is the SNAP protocol discriminator comprising six bytes.
In the preferred embodiment, the address resolution from the high level protocol stacks 551 to the data-link entities such as ELAP or TLAP residing at level 552 in the ISO-OSI model is performed by a process known as the AppleTalk.RTM.
The SNAP protocol discriminators 307 in ELAP packet 300 should contain $00000080F3 to indicate that it is an AARP packet being transmitted.

 RFC 2896 - Remote Network Monitoring MIB Protocol Identifier Macros
Any subsequent packets must be decoded and correctly identified by 'remembering' the port assignments used in each RPC function call (as identified according to the procedures in the RPC Specification Version 2 [RFC1831]).
Notice that in many implementations of IPX usage of the packet type field is inconsistent with the specification and implementations are encouraged to use other techniques to map inconsistent values to the correct value (which in these cases is typically the Packet Exchange Protocol).
In packets this same value would appear as (hex): 2-byte 37 35 6-byte AA 00 04 00 37 35 8-byte 00 00 AA 00 04 00 37 35 Notice that the AA 00 04 00 prefix is defined in the specification but is unimportant and should not be parsed.

 Re: Fwd: IPR Notification on RFC 2462 and 2464
When a node' AARP receives a Probe packet corresponding to one of its protocol stacks, it examines the protocol address of that stack.
If the probing node receives an AARP Response packet, then the tentative protocol address is already in use and the node must pick a new tentative address and repeat the probing process.

 Appletalk White Paper
The probe is repeated a number of times to increase the probability that all nodes will receive a copy.
If a response to a probe is received (i.e., another node has claimed the proposed address), the node proposes a new address, and repeats the probe process until it succeeds in acquiring an unused address, or until all assignable addresses are exhausted.
In addition to supporting AARP and RTMP, AppleTalk routers must support the Zone Information Protocol (ZIP), which is used to map network numbers to zone names on the network, and the Name Binding Protocol (NBP), which is used to bind names of network visible entities (e.g., printers or file servers) to AppleTalk addresses.

If the node ID is not being used, the sending node uses that node ID. If the node ID is being used, the sending node chooses a different ID and sends more AARP probe packets.
One node sends a packet to another node and receives a duplicate, or echo, of that packet.
APaRT recognizes specific data link layer encapsulation packet types and, when these packet types are transferred from one medium to another, translates them into the native format of the destination device.

 AARP - AppleTalk Address Resolution Protocol   (Site not responding. Last check: 2007-09-10)
AARP (AppleTalk Address Resolution Protocol) maps between any two sets of addresses at any level of one or more protocol stacks.
Specifically, it is used to map between AppleTalk node addresses used by the Datagram Delivery Protocol (DDP), as well as higher-level AppleTalk protocols, and the addresses of the underlying data link that is providing AppleTalk connectivity.
AARP makes it possible for AppleTalk systems to run on any data link.
