This is calculated on the assumption that traffic is transported over Ethernet, which has a usual MTU of 1500 bytes. On top of that, it must account for the IP/UDP/GTPv1U headers used to encapsulate the traffic sent towards the RAN. Hence the following bytes are subtracted from the Ethernet base MTU of 1500 bytes: +* IP: IPv4 headers can take up to 60 bytes (due to IPv4 options). IPv6 headers can take up to 40 bytes (assuming no extension headers for IPv6 in general, since they are uncommon). Hence, the 60 bytes of IPv4 are picked since that's greater than the IPv4. +* UDP: The UDP header takes 8 bytes. +* GTPv1U: The GTPv1U header takes 12 bytes, assuming here no extensions headers are used (OsmoGGSN doesn't use them). +Hence, `TUNNEL_MTU = ETH_MTU - IP_HDR - UDP_HDR - GTPv1U_HDR = 1500 - 60 - 8 - 12 = 1420`. + +Under certain networks, the base MTU may already be smaller than Ethernet's MTU (1500 bytes), due to, for instance, existence of some sort of extra tunneling protocol in the path, such as a VPN, ipsec, extra VLAN levels, etc. Under this scenario, the user must take care of figuring out the new base MTU value to use for the calculations presented above. This can be accomplished by packet inspection (eg. `wireshark`) or with tools such as `ping`, running it with a certain packet size and the IPv4 DF bit set, and see up to which packet size the networks is able to forward the message. For instance: + +.Example: Test if packets of 1420 bytes can reach peer host 176.16.222.4 +---- +ping -M probe 176.16.222.4 -s 1420 +---- + +==== TCP MSS Clamping + +Usually endpoints use Path MTU Discovery (PMTUD) to determine the maximum MTU to reach the peer. +However, this technique may sometimes not be successful for all users of OsmOGGSN: +* MS may not support requesting and/or configuring the MTU OsmoGGSN announced. +* MS may not support PMTUD on its network stack, or may not have it enabled or may be buggy. +* Network may be misconfigured or some middlebox may be buggy (eg. not forwarding ICMP `Packet Too Big` packets). + +Furthermore, PMTUD takes time to figure out the maximum MTU to use, since it relies on sending data and checking if it got lost, and adapting to the fact, reducing efficiency (throughput) of connections or even stalling them completely when big packets are generated. + +TODO: +- Explain what's TCP MSS +- Explain what's TCP MSS clamping and why is it useful in this case (we are reducing MTU from usual routes due to encapsulating traffic) +- Show an example with iptables on how to configure TCP MSS. + +==== Further Reading + +For more related specs, check the following specs: + +* 3GPP TS 29.061 section 11.2.1.5 +* 3GPP TS 290.060 section 13.2 IP Fragmentation +* 3GPP TS 25.414 section 6.1.3.3 +* 3GPP TS 23.060 section 9.3, Annex C +* 3GPP TS 24.008 (PCO IPv4 MTU) +* RFC 4861 (IPv6 Router Advertisement) + + === Multiple instances Running multiple instances of `osmo-ggsn` is possible if all GGSN instances -- To view, visit https://gerrit.osmocom.org/c/osmo-ggsn/+/38500?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: newchange Gerrit-Project: osmo-ggsn Gerrit-Branch: master Gerrit-Change-Id: Ib6e974b38107fe48072380f768e1881f0fc95e80 Gerrit-Change-Number: 38500 Gerrit-PatchSet: 1 Gerrit-Owner: pespin <pespin(a)sysmocom.de>
