Abstract
Examples of the present disclosure may provide a migration method. An emigration TR may receive a map notify message carrying a mapping relationship between an EID of the host and an RLOC of an immigration TR. The emigration TR may make a determination as to whether the RLOC of the immigration TR is same as an RLOC of the emigration TR. The emigration TR may search for an RLOC of a remote TR if the RLOC of the immigration TR is different from the RLOC of the emigration TR. The emigration TR may send an SMR message to the remote TR using the RLOC of the remote TR.
Claims14
A migration method, comprising:
- receiving, by an emigration Tunnel Router (TR), a map notify message carrying a mapping relationship between an Endpoint Identity (EID) of the host and a Routing Locator (RLOC) of an immigration TR;
- making, by the emigration TR, a determination as to whether the RLOC of the immigration TR is same as an RLOC of the emigration TR;
- searching for, by the emigration TR, an RLOC of a remote TR if the RLOC of the immigration TR is different from the RLOC of the emigration TR;
- sending, by the emigration TR, a Solicit Map Request (SMR) message to the remote TR using the RLOC of the remote TR to notify the remote TR of requesting for the RLOC of the immigration TR.
A migration method, comprising:
- receiving, by an immigration Tunnel Router (TR), a packet from the host;
- if a destination address of the packet is a Routing Locator (RLOC) of a remote TR and the packet is a first packet sent to the remote TR after the host migrates to the immigration TR, sending, by the immigration TR, a Solicit Map Request (SMR) message to the remote TR to notify the remote TR of requesting for an RLOC of the immigration TR.
A Tunnel Router (TR), wherein the TR is an emigration TR and the emigration TR comprises:
- a processor and
- a non-transitory storage medium storing machine readable instructions that are executable by the processor to:
- receive a map notify message carrying a mapping relationship between an Endpoint Identity (EID) of the host and a Routing Locator (RLOC) of an immigration TR;
- make a determination as to whether the RLOC of the immigration TR is same as an RLOC of the emigration TR;
- search for an RLOC of a remote TR if the RLOC of the immigration TR is different from the RLOC of the emigration TR;
- send a Solicit Map Request (SMR) message to the remote TR using the RLOC of the remote TR to notify the remote TR of requesting for the RLOC of the immigration TR.
A Tunnel Router (TR), wherein the TR is an immigration TR and the immigration TR comprises:
- a processor and a non-transitory- storage medium storing machine readable instructions executable by the processor to:
- receive a packet from the host;
- if a destination address of the packet is a Routing Locator (RLOC) of a remote TR and the packet is a first packet sent to the remote TR after the host migrates to the immigration TR, send a Solicit Map Request (SMR) message to the remote TR to notify the remote TR of requesting for an RLOC of the immigration TR.
The TR according to claim II, wherein the machine readable instructions further comprise instructions executable by the processor to:
- receive a map request message carrying the RLOC of the remote TR and an Endpoint Identity (EID) of the host from the remote TR;
- and)
- send a map response message carrying the EID of the host and the RLOC of the immigration TR to the remote TR.
