19、m Protocol 4 Requirements Catalogue The mobility requirements related to Internet Protocol version 6 (IPv6) are specified in a number of IETF documents. These documents include requirements for the overall IPv6 mobility architecture 2, the use of the IP Security (IPsec) 3, tunnelling MIPv6 packets 1
20、 and fast handover 4. The present document is a catalogue of all of the normative requirements from these mobility specifications. Each requirement is given a unique identifier (for example, RQ_001_1234) and the following information is included with each: the clause number in the RFC from which the
21、 requirement has been extracted; the type of requirement (Mandatory, Optional or Recommended); the type of device to which the requirement applies (for example, Mobile Node or Home Agent); the actual text from which the requirement was extracted. 4.1 Requirements extracted from RFC3775 Identifier: R
22、Q_001_1001 RFC Clause: 1 Type: Mandatory Applies to: Mobile_Node Requirement: Mobile IPv6 SHALL enable a mobile node to move from one link to another without changing the mobile nodes “home address“. RFC Text: The protocol defined in this document, known as Mobile IPv6,allows a mobile node to move f
23、rom one link to another without changing the mobile nodes “home address“. Packets may be routed to the mobile node using this address regardless of the mobile nodes current point of attachment to the Internet. The mobile node may also continue to communicate with other nodes (stationary or mobile) a
24、fter moving to a new link. Identifier: RQ_001_1002 RFC Clause: 1 Type: Optional Applies to: Mobile_Node Requirement: Packets may be routed to the mobile node using its home address regardless of the mobile nodes current point of attachment to the Internet. RFC Text: The protocol defined in this docu
25、ment, known as Mobile IPv6, allows a mobile node to move from one link to another without changing the mobile nodes “home address“. Packets may be routed to the mobile node using this address regardless of the mobile nodes current point of attachment to the Internet. The mobile node may also continu
26、e to communicate with other nodes (stationary or mobile) after moving to a new link. ETSI ETSI TS 102 559 V1.1.1 (2006-12) 7 Identifier: RQ_001_1003 RFC Clause: 1 Type: Optional Applies to: Mobile_Node Requirement: The mobile node CAN also continue to communicate with other nodes (stationary or mobi
27、le) after moving to a new link RFC Text: The protocol defined in this document, known as Mobile IPv6, allows a mobile node to move from one link to another without changing the mobile nodes “home address“. Packets may be routed to the mobile node using this address regardless of the mobile nodes cur
28、rent point of attachment to the Internet. The mobile node may also continue to communicate with other nodes (stationary or mobile) after moving to a new link. Identifier: RQ_001_1004 RFC Clause: 4 Type: Mandatory Applies to: Mobile_Node Requirement: A mobile node is addressable at its home address,
29、whether it is currently attached to its home link or is away from home RFC Text: A mobile node is always expected to be addressable at its home address, whether it is currently attached to its home link or is away from home. The “home address“ is an IP address assigned to the mobile node within its
30、home subnet prefix on its home link. While a mobile node is at home, packets addressed to its home address are routed to the mobile nodes home link, using conventional Internet routing mechanisms. Identifier: RQ_001_1005 RFC Clause: 4.1 Type: Mandatory Applies to: Mobile_Node Requirement: While a mo
31、bile node is attached to some foreign link away from home, it is also addressable at one or more care-of addresses RFC Text: While a mobile node is attached to some foreign link away from home, it is also addressable at one or more care-of addresses. A care-of address is an IP address associated wit
32、h a mobile node that has the subnet prefix of a particular foreign link. The mobile node can acquire its care-of address through conventional IPv6 mechanisms, such as stateless or stateful auto-configuration. As long as the mobile node stays in this location, packets addressed to this care-of addres
33、s will be routed to the mobile node. The mobile node may also accept packets from several care-of addresses, such as when it is moving but still reachable at the previous link.

34、rement: Support bidirectional tunneling using IPv6 encapsulation between the Home Agent and the mobile node RFC Text: There are two possible modes for communications between the mobile node and a correspondent node. The first mode, bidirectional tunneling, does not require Mobile IPv6 support from t
35、he correspondent node and is available even if the mobile node has not registered its current binding with the correspondent node. Packets from the correspondent node are routed to the home agent and then tunneled to the mobile node. Packets to the correspondent node are tunneled from the mobile nod
36、e to the home agent (“reverse tunneled“) and then routed normally from the home network to the correspondent node. In this mode, the home agent uses proxy Neighbor Discovery to intercept any IPv6 packets addressed to the mobile nodes home address (or home addresses) on the home link. Each intercepte
37、d packet is tunneled to the mobile nodes primary care-of address. This tunneling is performed using IPv6 encapsulation 15. Identifier: RQ_001_1006 RFC Clause: 4.1 Type: Optional Applies to: Mobile_Node Requirement: Support bidirectional tunneling using IPv6 encapsulation between the Home Agent and t
38、he mobile node RFC Text: There are two possible modes for communications between the mobile node and a correspondent node. The first mode, bidirectional tunneling, does not require Mobile IPv6 support from the correspondent node and is available even if the mobile node has not registered its current
39、 binding with the correspondent node. Packets from the correspondent node are routed to the home agent and then tunneled to the mobile node. Packets to the correspondent node are tunneled from the mobile node to the home agent (“reverse tunneled“) and then routed normally from the home network to th
40、e correspondent node. In this mode, the home agent uses proxy Neighbor Discovery to intercept any IPv6 packets addressed to the mobile nodes home address (or home addresses) on the home link. Each intercepted packet is tunneled to the mobile nodes primary care-of address. This tunneling is performed
41、 using IPv6 encapsulation 15. Identifier: RQ_001_1007 RFC Clause: 4.1 Type: Optional Applies to: Mobile_Node Requirement: the mobile node MAY register its current binding at the correspondent node RFC Text: The second mode, “route optimization“, requires the mobile node to register its current bindi
42、ng at the correspondent node. Packets from the correspondent node can be routed directly to the care-of address of the mobile node. When sending a packet to any IPv6 destination, the correspondent node checks its cached bindings for an entry for the packets destination address. If a cached binding f
43、or this destination address is found, the node uses a new type of IPv6 routing header 11 (see Section 6.4) to route the packet to the mobile node by way of the care-of address indicated in this binding.

44、pplies to: Mobile_Node Requirement: Mobile Nodes shall support “dynamic home agent address discovery“ RFC Text: Mobile IPv6 also provides support for multiple home agents, and a limited support for the reconfiguration of the home network. In these cases, the mobile node may not know the IP address o
45、f its own home agent, and even the home subnet prefixes may change over time. A mechanism, known as “dynamic home agent address discovery“ allows a mobile node to dynamically discover the IP address of a home agent on its home link, even when the mobile node is away from home. Mobile nodes can also
46、learn new information about home subnet prefixes through the “mobile prefix discovery“ mechanism. These mechanisms are described starting from Section 6.5. Identifier: RQ_001_1009 RFC Clause: 4.1 Type: Optional Applies to: Mobile_Node Requirement: Mobile nodes MAY learn new information about home su
47、bnet prefixes through the “mobile prefix discovery“ mechanism RFC Text: Mobile IPv6 also provides support for multiple home agents, and a limited support for the reconfiguration of the home network. In these cases, the mobile node may not know the IP address of its own home agent, and even the home
48、subnet prefixes may change over time.

Mobile nodes can also learn new information about home subnet
49、prefixes through the “mobile prefix discovery“ mechanism. These mechanisms are described starting from Section 6.5. Identifier: RQ_001_1010 RFC Clause: 4.6 Type: Mandatory Applies to: Mobile_Node Requirement: home addresses MUST be unicast routable addresses RFC Text: This specification requires that home and care-of addresses MUST be unicast routable addresses. Site-local addresses may be usable on networks that are not connected to the Internet, but this specification does not define when such usage is safe and when i
