# Command: % ltpadmin loopback.ltprc
# This command should be run AFTER ionadmin and BEFORE bpadmin.

# A warning: the ltp configuration is not ideal in this case.

# better description.
# Initialization command (command 1).
# Establishes the LTP retransmission window.
# (Prohibiting LTP from seizing all available storage).
# A maximum of 32 sessions. A session is assumed to be around one
# second of transmission. This value should be estimated at the sum
# of maximum round-trip times (in seconds) for all "spans."
# Suggest throwing 20% higher number of sessions to account for extra-
# long sessions which contain an actual retransmission.
# Set a total LTP memory space usage limit as the sum of the memory
# space usage of all spans (more or less the number of bytes in transit
# on all links for their duration).

# Add a span. (a connection)
# Identify the span as engine number 1. That is the ipn node number
# of the node on the other end of this span.
# Use 128 as the maximum number of export sessions.
# Use 1024 as the maximum size of an export block. This more or less
# limits the maximum size of a bundle in the system.
# The next two items are the maximum number of import sessions and the
# maximum size of an imported block. Since this is loopback, we just
# copy the export numbers here.
# 1024 is the maximum segment size- more or less, the amount of data
# that can be held in a single frame of the underlying protocol. In
# this case, UDP packets are the frame, and we will give a conservative
# limit.
# Limit the aggregation size to 1024 bytes, and set a time limit on
# aggregation to 1 second.
# Use the command 'udplso localhost:1113' to implement the link
# itself. In this case, we use udp to connect to localhost (this is
# loopback) using port 1113 (defined by IANA as the default UDP port
# for Licklider Transmission Protocol). The single quote is
# important, don't use double quotes.

# Start command.
# This command actually runs the link service output commands
# (defined above, in the "a span" commands).
# Also starts the link service INPUT task 'udplsi localhost:1113' to
# listen on UDP port 1113 for incoming LTP traffic.
