Thank you for reply。 In our scenario，we use the Intel ‘s DDP feature to hash different GTP packets into different threads。And We want the GTP packets from the same UE to be hashed on the same thread，DDP can‘t implement this function。 So we consider using the Handoff mechanism 。But We still have some doubts. （1） We know VPP ensure efficiency by deal one group packets by the same thread's nodes，if we use handoff ，how much does this mechanism affect efficiency?Or is there any other mechanism to meet our requirements? （2）If we use Handoff，Which method is better: a) Dealing GTP packet RSS without using devices， use software RSS，use one Thread receive All packets，then handoff to other threads b) Dealing GTP packet RSS with using devices, when the thread receive packet, determine if the current thread need to deal this packet，if not，handoff to other thread。
