Introduction This memo defines a Management Information Base (MIB) module which describes managed objects for RSerPool implementations. 2. The Reliable Server Pooling (RSerPool) Framework For a detailed overview of the documents that describe the current Reliable Server Pooling (RSerPool) framework, please refer to [RFC3237], [RFC5351], [RFC5352], [RFC5353], [RFC5354], [RFC5355] and [RFC5356]. A more informal introduction can be found at [RSerPoolPage]. 3. The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 4.

shows, the MIB consists of three main branches: "enrpServers", "poolElements" and "poolUsers". The first branch, "enrpServers" is used to access managed objects in the set of ENRP servers running on a given host. While it is assumed that it does not make much sense to run multiple ENRP servers for the same operation scope on one host, running multiple ENRP servers for different operation scopes is very likely when the ENRP server processes run on routers. Therefore, the MIB has to be able to manage multiple ENRP servers on the same host. "poolElements" is used to access managed objects in the set of Pool Elements that are running on a given host and the third branch, "poolUsers" is used to access managed objects in the set of Pool Users that are running on a given host. In fact, the structure of the three branches is very similar. Because the two branches are so similar, we describe only the first branch in detail, and provide a summary description of the second and third branch. We now proceed with a description of the branches. 4.1. Access to managed objects on ENRP servers The first branch describes managed objects at a set of ENRP servers. Any given ENRP server of this set will, at a certain moment in time, Dreibholz & Mulik Expires May 21, 2009 [Page 9] Internet-Draft RSerPool MIB November 2008 have registration information for a set of active pools. Each of these pools in turn may have a list of pool elements that are registered under that pool. To allow this information to be retrieved via SNMP, the ERNP server branch of the RSerPool MIB uses the table-in-table technique described in [SNMPMIBS]. Specifically, the ENRP servers branch creates four levels of nesting, as indicated in the following diagram: Nesting of ENRP Server Branch Nesting Structure: Level 1: enrpServerTable Level 2: enrpServerPoolTable Level 3: enrpServerPoolElementTable Level 4: enrpServerASAPAddrListTable enrpServerUserAddrListTable Level 2: enrpServerENRPAddrListTable Level 2: enrpServerPeerTable Level 3: enrpServerPeerAddrListTable The ENRP servers branch contains a table of the host's ENRP server instances. Its purpose is to provide an index to an ENRP server for all other tables. Each "conceptual row" in the enrpServerTable contains the server's ENRP Identifier, the number of pools, PEs and peers, the amount of ENRP endpoint addresses, the server's uptime and a textual description of the server. The poolTable contains a single entry for each pool that is currently registered. Each "conceptual row" in the enrpServerPoolTable consists of a enrpServerPoolTableEntry, with two elements: a enrpServerPoolIndex and an OCTET STRING representation of the pool handle. The enrpServerPoolIndex is simply an integer that is used to index into the enrpServerPoolTable and the enrpServerPoolElementTable. The value of this integer is between zero and (poolCount - 1). Note that the value of enrpServerPoolIndex is defined as "not-accessible" in the MAX-ACCESS clause; this is a standard technique used when defining a table-in-table data structure. The third element on the ENRP servers branch is the enrpServerPoolElementTable. Because the enrpServerPoolElementTable is the "inner" table of the table-in-table structure, its index consists of a pair, as indicated in the clause "INDEX { enrpServerIndex, enrpServerPoolIndex, enrpServerPoolElementIndex }". The fourth element of the ENRP servers branch takes the nesting to one additional level, listing the Dreibholz & Mulik Expires May 21, 2009 [Page 10] Internet-Draft RSerPool MIB November 2008 various addresses associated with a particular enrpServerPoolElement in form of ASAP endpoint addresses and user transport addresses, and thus are indexed by the 4-tuples "INDEX { enrpServerIndex, enrpServerPoolIndex, enrpServerPoolElementIndex, enrpServerASAPAddrListTableIndex }" and "INDEX { enrpServerIndex, enrpServerPoolIndex, enrpServerPoolElementIndex, enrpServerUserAddrListTableIndex }". The ENRP endpoint addresses of an ENRP server are bound to its instance in the enrpServerENRPAddrListTable by "INDEX { enrpServerIndex, enrpServerENRPAddrListTableIndex }". Finally, an ENRP server has a peer table of its known peers. They are bound to a server instance by the enrpServerPeerTable; analogously, the addresses of a peer are bound to a peerTable's entry in the peerAddrListTable. 4.2. Access to managed objects on Pool Elements The construction of the Pool Elements branch is very similar to the pool elements table of the ENRP servers branch. But instead of grouping the pool elements into pools (which does not make sense here), the pool elements table is the top of the hierarchy and each pool element entry specifies its operation scope and pool handle. That is, the nesting structure is as follows: Level 1: poolElementTable Level 2: poolElementASAPAddrListTable poolElementUserAddrListTable The description of the contained structures is the same as for the ENRP servers branch. TODO: There should be the server table (ENRP servers learned by their announces) plus the multicast address the PE expects the announces to be sent to. 4.3. Access to managed objects on Pool Users For the pool users branch, it is only necessary to list the pool users, including their operation scope and pool handle. TODO: There should be the server table (ENRP servers learned by their announces) plus the multicast address the PE expects the announces to be sent to. 5.

Security Considerations SNMPv1 by itself is not a secure environment. Even if the network itself is secure (for example by using IPSec), there is no control as to who on the secure network is allowed to access and GET/SET (read/ change/create/delete) the objects in this MIB. It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2574 [RFC2574] and the View- based Access Control Model RFC 2575 [RFC2575] is recommended. It is then a customer/user responsibility to ensure that the SNMP entity giving access to an instance of this MIB, is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/ create/delete) them. 7. IANA Considerations IANA will need to assign an OID prefix for the RSerPool MIB. 8. Acknowledgments The authors would like to express a special note of thanks to Phillip Conrad and Kevin Pinzhoffer for their efforts in the early formation of this draft. Also, the authors would like to thank Nihad Cosic, Dirk Hoffstadt, Michael Kohnen, Jobin Pulinthanath, Randall Stewart, Michael Tuexen and Xing Zhou for their support. 9. References 9.1.
