ETR (Egress TR exports TR)；
Maintenance has the mapping relations of the EID and RLOC of this website on all ETR of each LISP website, and ETR is periodical
The mapping relations of the EID of this website and RLOC are sent to mapping server by mapping registration (Map-Register) message by ground
(MS, Map Server).
2) Map DB (Map DataBase, mapping database): the mapping database of EID to RLOC includes RLOC and EID
Mapping relations, be stored on MS；
MS receives the Map-Register message that ETR is sent, and the mapping relations of EID and RLOC in message are stored in
In Map DB.
3) PxTR (Proxy xTR): acting on behalf of xTR, at the network boundary for not supporting positioned at support LISP and LISP.
LISP realizes the separation of core net and edge net by ITR and ETR, it is used to realize by a mapped system
Mapping Resolution from EID to RLOC.LISP realizes road in the core network by the encapsulation and decapsulation mechanism of IP-in-IP
By and forwarding.
By taking Fig. 1 as an example, when host 2 of the host 1 in LISP website A into LISP website B sends data, host 2
EID is non-routable in the core network；After data packet reaches ITR, the local mapped cache (Map Cache) of ITR discovery
In do not have save host 2 the corresponding RLOC of EID, then to MR (Map Resolver, Mapping Resolution device) send Map-Request
Map-Request message is transmitted to MS with the corresponding RLOC of the EID for inquiring host 2, MR by message, and MS is looked into local MapDB
Find the RLOC of the corresponding ETR of EID of host 2, Map-Request message is transmitted to ETR by MS, ETR by the EID of host 2 and
The RLOC carrying of oneself returns to ITR in Map-Reply message；Then ITR encapsulates the data packet, using the RLOC of oneself as source
Address, using the RLOC of opposite end ETR as purpose address, while the RLOC for saving in Map Cache the EID and ETR of host 2 reflects
Penetrate relationship；Opposite end ETR decapsulates the packet after receiving the packet, finally delivers a packet to host 2.
In LISP network, host can be migrated, as shown in Fig. 2, vCenter (virtual center) controls VM (Virtual
Machine, virtual machine) migration, if at a time, vCenter is determined VM B from DC (Data Center, in data
The heart) 1 move to DC2, then specific transition process is as follows:
Step 01:VM B moves to DC2 from DC1, and ETR4 receives the gratuitous ARP (Address of VM B sending
Resolution Protocol, address resolution protocol) message or data message, so that ETR4, which perceives VM B, moves to this
Under ETR；
Step 02:ETR4 notifies VM B to move by multicast Notify message to other ETR (ETR3) of this two layers net
DC2, and pass through the EID that Map-Register message registers VM B to MS；
XTR1 of the step 03:MS into DataCenter1 sends Map-Notify notice message, and notice VM B moves out.
After xTR1 receives Map-Notify message, virtual machine VM B information is deleted；
In order to safeguard the map information between EID and RLOC on MS, when there is host to move into, xTR needs instant to MS
Map-Register message is sent, to register the host information newly moved into, and, xTR needs periodically to send Map- to MS
Register message, to register the All hosts information for moving into itself.
