Line 27:
== Datagram Encapsulation and IP MTU size==
[[Internet Protocol|Internet Protocol (IP)]] can use AAL5,
AAL5 uses a 16-bit length field, making it possible to send 65,535 (2^16-1) octets in a single packet. However, RFC 2225 specifies a default MTU of 9180 octets per datagram, so, unless the hosts on both ends of the virtual circuit negotiate a larger MTU, IP datagrams larger than 9180 octets will be fragmented.
