PMIP: Multipath Support on MAG and LMA

The PMIP: Multipath Support on MAG and LMA feature enables Mobile Access Gateway (MAG) to register multiple transport end-points with Local Mobility Anchor (LMA), allowing MAG and LMA to establish multiple tunnels and apply path selection on a flow basis.

Information About PMIP: Multipath Support for MAG and LMA

Local Mobility Anchor

Local Mobility Anchor (LMA) is the home agent for a mobile node (MN) in a Proxy Mobile IPv6 (PMIPv6) domain. It is the topological anchor point for MN home network prefixes and manages the binding state of an MN. An LMA has the functional capabilities of a home agent as defined in the Mobile IPv6 base specification (RFC 3775) along with the capabilities required for supporting the PMIPv6 protocol.


Note

Use the dynamic mag learning command to enable LMA to accept Proxy Mobile IPv6 (PMIPv6) signaling messages from any Mobile Access Gateway (MAG) that is not configured locally.

Mobile Access Gateways

Mobile Access Gateway (MAG) performs mobility-related signaling on behalf of the mobile nodes (MN) attached to its access links. MAG is the access router for the MN; that is, MAG is the first-hop router in the localized mobility management infrastructure.

MAG performs the following functions:

  • Obtains an IP address from Local Mobility Anchor (LMA) and assigns it to MN.

  • Retains the IP address of an MN when the MN roams across MAGs.

  • Tunnels traffic from MN to LMA.

Mobile Node

Mobile node (MN) is an IP host and the mobility of the MN is managed by a network. MN can be an IPv4-only node, an IPv6-only node, or a dual-stack node, which is a node with IPv4 and IPv6 protocol stacks. MN is not required to participate in any IP mobility-related signaling for achieving mobility for an IP address or a prefix that is obtained in the Proxy Mobile IPv6 (PMIPv6) domain.

Multipath Support

At any given time, many network paths exists between Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG). The PMIP: Multipath Support on MAG and LMA feature enables MAG to select any one of the paths on priority basis or select all the existing network paths simultaneously to create tunnels to reach LMA. All paths have the same priority when multiple paths are selected.

Mobile Map

Mobile map configuration facilitates application-based routing. More than one mobile map can be configured under the Proxy Mobile IPv6 (PMIPv6) domain, however, at a given point of time, only one mobile map is active at Mobile Access Gateway (MAG) and Local Mobility Anchor (LMA). The mobile map and its entries are configured or modified when no bindings are available.

Logical Mobile Node

Logical Mobile Node (LMN) is a logical entity that represents a mobile node (MN) that is hosted on one of the interfaces of Mobile Access Gateway (MAG) device. LMN has Network Access Indicator (NAI) similar to MN. One or more networks can be associated with each LMN through the interfaces designated as mobile network interfaces. LMN on mobile network receives an IP address from a DHCP server that runs on MAG, unlike a mobile node whose address is assigned by Local Mobility Anchor (LMA).

Multipath Management

The PMIPv6 Mutipath Management feature enables PMIPv6 to choose from multiple available links which have different access technologies. Available path is constantly monitored using PMIPv6 heartbeat which is a special type of PMIPv6 packet. Link preferences can be assigned to various types of traffic using mobile maps.

Hybrid-Access Service

Hybrid-access service is a multipath management solution, which provides mobility service under MAG. PMIPv6 hybrid-access service is an independent function that manages application profiles, captures and stores link performance statistics, and programs the PMIPv6 data plane based on the application requirements (HTTP, SSH, Telnet, and video).


Note

PMIPv6 hybrid-access service has no interference with the core PMIPv6 functionality.

MAG to MAG Traffic Blocking on the PMIPv6 LMA

To prevent communication between PMIPv6 clients such as, mobile nodes (MNs), or entire mobile networks, that are connected to the same Local Mobility Anchor (LMA), the inter-MAG tunnel traffic is blocked by applying access control list (ACL) on the PMIPv6 tunnels. To enable the blockage of inter-MAG tunnel traffic, the prefixes of all the PMIPv6 addresses mentioned in the address pool configured on LMA, must be entered in the ACL.

                          PMIP: Multipath Support on MAG and LMA

                          The PMIP: Multipath Support on MAG and LMA feature enables Mobility Access Gateway (MAG) to register multiple transport end-points with Local Mobility Anchor (LMA), allowing MAG and LMA to establish multiple tunnels and apply path selection on a flow basis.

                          The following commands were introduced or modified: encap (proxy mobile IPv6), heartbeat, interface (proxy mobile IPv6) , match access-list (PMIPv6), mobile-map (PMIPv6 domain), mobile-map (LMA), mobile-network PMIPv6), multipath, set link-type, tunnel mtu, .

                          PMIPv6 Multipath Management

                          The PMIPv6 Mutipath Management feature enables PMIPv6 to choose from multiple available links which have different access technologies.

                          The following commands were introduced or modified: address dynamic, bce maximum, default profile, dynamic mag learning, heartbeat, jitter, match access-list, mobile-map, mobility-service hybrid-access, packet loss, profile-definition, rtt, set link-type, traffic-profile.
