Packet Fragmentation in IPv6 over IPv4 Tunnels
نویسندگان
چکیده
Nowadays IPv6 over IPv4 tunnels are widely used to form the global IPv6 Internet. This paper analyzes a packet fragmentation problem in IPv6 over IPv4 tunnels due to the MTU difference between IPv6 and IPv4 layers, which would greatly degrade the performance of the tunnels if ever happened. It also demonstrates an ICMP based attack that could induce the problem and gives some advice on how to deal with such attacks.

Monitoring of Tunneled IPv6 Traffic Using Packet Decapsulation and IPFIX (Short Paper)
IPv6 is being deployed but many Internet Service Providers have not implemented its support yet. Most of the end users have IPv6 ready computers but their network doesn’t support native IPv6 connection so they are forced to use transition mechanisms which transports IPv6 packets through IPv4 network. Unfortunately deployment of IPv6 is slow and at this rate, completion of the migration from IPv...
متن کاملIPv6 delay and loss performance evolution
Although packet delay and loss are two important parameters of the Internet performance, to the best of our knowledge, the evolution of large-scale IPv6 delay and loss performance has previously not been studied. In this paper, we analyze more than 600 end-to-end IPv6 paths between about 26 testboxes of RIPE Network Coordination Centre over two years, and compare the delay and loss performance ...
متن کاملInternet Draft Routing Aspects Of IPv 6 Transition November 1994
This paper discusses routing aspects associated with the transition from IPv4 to IPv6. The approach outlined here is designed to be compatible with the Simple Internet Transition (SIT) mechanism. The proposals contained in this document are the opinions of the authors, and have not yet been discussed in detail by the working group. This document is intended as input to the IPNG, Tacit, and Ngtr...
متن کاملRFC 5747 4 over 6 March 2010
The emerging and growing deployment of IPv6 networks will introduce cases where connectivity with IPv4 networks crossing IPv6 transit backbones is desired. This document describes a mechanism for automatic discovery and creation of IPv4-over-IPv6 tunnels via extensions to multiprotocol BGP. It is targeted at connecting islands of IPv4 networks across an IPv6-only backbone without the need for a...
متن کاملNetwork Optimization of Ipv6 Networks Using Tunnel Header Compression
IPv6 is the successor internet protocol which will eventually replace IPv4. These two protocols are not compatible with each other and it will take time to migrate towards IPv6, until then both the protocols need to coexist for a long time. The main overhead involved with both the protocols is header length of 20 bytes in case of IPv4 and of 40 bytes in case of IPv6. This overhead will affect t...
