Hi;Could i have answers about the following:1- Is this the reason of why IPsec pre-fragmentation feature can't be supported for IPv6, and the fragmentation by the IPv6 packet sender before IPsec encryption doesn't considered as pre-fragmentation beca...
Hi ; Could the feature of IPsec pre-fragmentation be applied for packets with IPv6? Why and how? Are there any authorized papers or researches prove that? If any; could you provide me with useful ones, please? Thanks Rose
Hi;First: In the ESP tunnel mode of the IPSEC :1. Is the IP ID field of the inner IP header encrypted?2. Is the IP ID field of the outer IP header different of that of the IP header?3. Is the sequence number field of the TCP header ...
Hi; The structure of the IP header may be a 5 words of 32 bits including the following fields: - Version (4bits) , IHL (4bits) , TOS (8 bits), Total length(16 bits)- Identification (16 fields), flags(3 bits) , fragment offset ( 13 bi...
I'm going to study two features on security and network performance, which are: 1- Pre-fragmentation (look ahead fragmentation) 2- Link fragmentation and Interleaving I have some questions that need your help to answer the following:> 1- Which cisc...
Hi everybody;How are you Wen.?So for IPv6 fragmentation is allowed only by packet sender; but what the followings: 1- Is this the reason of why IPsec pre-fragmentation feature can't be supported for IPv6, and the fragmentation by the IPv6 packet send...
Hi Wen;I'm happy for replying me. RFC2460 is a good resource for IPv6 specifications but it’s not discussing the case of IPSec tunnels. While the fragmentation would be performed by the source node if needed and encryption would be done by the encryp...
Hi Marcin;Do you see fragmentation of pre-encapsulation packets happening?Yes; double fragmentation could be occured if the size of the pre-fragmented packet is larger than the MTU of the transmiision link; but this is not my question.Could i have an...
