+# The `fixedlength` framing function
+
+The `fixedlength` peer stream framing function segments the peer stream into binary frames
+at fixed byte boundaries (for example, aggregating and then sending 32-byte fragments from the
+peer stream).
+
+## Configuration
+
+The framing configuration string is simply the length of the segments to transmit in bytes.
