		IEN 32 Section 2.3.3.12 Title: Catenet Monitoring and Control: A Model for the Gateway Component Author: John Davidson [Davidson@BBNE] Note: This document contains figures which are not included in this on line version, the figures may be obtained in hardcopy from the author.
		However, coordination is not achieved by default, because the Catenet is being constructed in pieces, with each piece potentially under the control of a distinct administrator, each gateway implemented in a unique processor, and each program conforming to a different programmer's view of the workings of a gateway.
		Both the GMCC program(s) and its data base(s) should be described in a way which allows Catenet users to reproduce the GMCC functions (this basically requires coding of the GMCC programs in a high order language) and to interrogate or duplicate the accumulated data base(s) as required for their own special purposes.

	Catenet - Wikipedia, the free encyclopedia
		Catenet is an obsolete term for a system of packet-switched communication networks interconnected via gateways.
		It was coined at a time when network meant what is now called local area network, to refer to the concept of linking these networks into a "network of networks".
		The term "internet" (with a lower-case 'i'), referring to any network speaking the Internet protocol has superseded the term "catenet", as IP is the only cross-networking protocol in wide use.

		The role of the catenet is to avoid congestion in the gateways (and elsewhere in the catenet where possible), by giving these stream packets priority in the gateway queues.
		A consequence of this definition of stream traffic support is that it becomes meaningful for the catenet to offer a number of distinct priority classes, rather than simply flagging the packet as 'priority', as priority becomes a defined function of the gateways.
		In this case, the maximum packet size supportable by the catenet on an unfragmented basis is a parameter which must be known by the end processes.

		All gateways which are visible to the catenet model have the characteristic that they can interpret the address 2 fields of internet datagrams so as to route them to other gateways or to destinations within the networks directly attached to (or associated with) the gateway.
		The set of catenet gateways are assumed to exchange with each other at least a certain minimum amount of information to enable routing decisions to be made, to isolate failures and identify errors, and to exercise internet flow and congestion control.
		Access control is defined, at the catenet gateway, to mean "permitting traffic to enter or leave a particular network." The criteria by which entrance and exit permission are decided are the responsibility of network "access controllers" which establish access control policy.

		Datagrams which are to be transmitted through the Wideband Net are wrapped in a layer of catenet protocol, which is common to the entire Wideband Net, followed by a (possibly null) layer of protocol which is dictated by the particular network that the datagram is traversing.
		The catenet protocol header is considered to be part of the datagram, and is preserved (with only minor changes) as the datagram traverses the various constituent networks.
		catenet: A collection of two or more networks, arbitrarily interconnected by gateways, in which the communicating hosts have agreed, a-priori, on some canonical "catenet protocol" which is used for datagram transport.

		The first situation discussed was the user at a catenet terminal, who discovers that he either cannot connect to a particular destination host or that he no longer gets any response from his previously working connection.
		The primary purpose of a monitoring or control center in terms of fault isolation is to isolate the component (network or gateway) that failed and to notify the proper authority to have it fixed.
		From the technical point of view, it was pointed out that the catenet could become partitioned such that the control center was cut off from part of the catenet and thus could no longer handle faults in that portion of the catenet.

		Introduction The majority of this note was originally written to address a wider problem than measurements solely within the ARPA catenet and the orientation of the discussion is therefore in those terms.
		Given the rapid proliferation of networks and the corresponding increase in the variety of their type and interconnection, it is felt that the facilities should not be tightly bound to a particular protocol but should be supportable across as many networks as possible.
		In measurements beyond the ARPA catenet the internet header may well be lost in traversing other networks where gateways may, for example, do protocol conversion at the transport level.

		The described algorithm modifications were defined as a result of problems encountered in the implementation of the gateway to gateway control protocol specified in IEN # 109.
		Other Possible Approaches Redundant Role Restricting the use of non-routing gateways in the catenet to locations where they provide the only configured path and adoption of the corresponding rule changes is our recommended solution to the implementation problems we've identified.
		Thus, the decision to sacrifice catenet reliability in favor of increased traffic flow would be made by the parties involved without involving any gateway control function awareness or participation.

		Assuming some of these pieces are still connected to the catenet, we would like the catenet to be able to efficiently deliver packets to a host in any such piece.
		Such a capability in the catenet could additionally be utilized by a scheme for delivering intranet traffic across partitions in a partitioned network.
		There are aspects to the scheme that are irrelevant to a discussion of how to solve the network partition problem, such as sequence numbers for link state reports, etc. The purpose of this paper is to direct a correct approach to the design, and not to present an implementation specification.

		CATENet continues to grow daily, picking up members through both the CATE web site and my own, as well as word of mouth.
		So I feel that it remains essentially a California forum but, because California so often precedes the rest of the country in certain trends (good and bad), one that speaks to the rest of the country.
		Finally, CATENet has achieved a new or deeper feeling of community as reflected by such contributions as Ruth Nathan whose reflections on her teaching draw powerful and personal reactions from others.

		Also, when the name of a partition changes, the rest of the gateways on the catenet must be informed of that fact so that they will stop reporting about obsolete partition names in their distance vectors.
		As currently implemented in the catenet, nodes report their distance to a destination as "infinity" (a number higher than the maximum possible distance in the catenet) when reporting to downstream neighbors.
		There are new features that the catenet is scheduled to provide, most notably extended routing, in which the functional differences between links are recognized and accounted for.

		Ideally, the Catenet routing algorithms, implemented in the gateways, should be capable of knowing the full UK-US connectivity without the UK being used as an expressway for US-US traffic.
		In the present Catenet design and with the present Catenet protocols, such full knowledge by the gateways would have to be constrained by specifying source and return routes in each IP datagram.
		However the UK is not alone in its problems, and in a general Catenet we can imagine a large number of paths having a number of user classes giving a very large class- problem space.

		In order to provide help to the catenet in figuring a route it allows the user to provide a sequence of addresses such that each of them is locally unique (hence unambiguous and known) where it is supposed to be interpreted.
		The choice of route from each address to the next is left to the catenet to determine.
		Since the source routing technique which was described above does not tell the catenet how to route messages between the given addresses, it is possible for messages to be routed through foes while traversing a sequence of friendly addresses.

		For example, the way in which hierarchical addressing is incorporated into Catenet addressing mechanisms has recently come under criticism in IEN 177 by Danny Cohen, who focuses his criticism on the particular case of the ARPANET.
		It now seems to be more generally accepted that the current Catenet gateways provide inadequate performance, and that building a robust operational internet system requires us to build Switches that are large enough to handle the required functionality at a reasonably high level of performance.
		This is a very important difference between our proposed scheme and the scheme presently implemented in the Catenet, where a source Switch which is also a potential destination Switch is highly constrained to pick itself as the actual destination Switch.

		Since Catenet protocols are being brought to the UK, the conversion facilities must in general be in the UK; in particular, they will be at UCL.
		For interactive terminal service, the protocols used on the Catenet and the UK sides of the gateway differ at both the transport level and the user level.
		On the Catenet side, a true transport protocol with end-to-end addressing is needed, since the X25 call is to be "concatenated" with the TCP connection.

		It is reasonable for the catenet to know enough about nets to take into account their properties when calculating internet routes.
		However, the catenet should route to destination networks based solely on the most efficient internet route to that network, and let the destination network handle delivery to the host on the network as it sees fit.
		A network that was not originally designed as part of the catenet should be able to be connected to the catenet merely by adding a gateway to that net.

		We also believe that all of our hosts are constituents of the catenet, not of any particular network, including the WBnet.
		By this we mean that any host should be addressable via any of the catenet networks to which it has a connection.
		It is not clear to us at all why all of our hosts should pledge their allegiance to W-16 addressing scheme and to the WBC for which it stands, one network, indivisible (enough!!).

		It is true, as we have said, that within the Network Structure of the Catenet, we want to regard the ARPANET as a Pathway whose internal structure we do not have to deal with, but that does NOT mean that we should regard it as a circuit.
		In the current Catenet, hosts have to know in advance how to identify the Catenet gateways on their networks (although there are certain restricted circumstances under which a host can obtain the name of another gateway from a gateway about which it already knows).
		The solution that has been adopted in the current Catenet is to allow the internet Switches to "fragment" the packets into several pieces whenever this is necessary in order to send the packet over a Pathway with a small maximum packet size.

		Another example of a Network Structure is one whose Switches are the gateways on the ARPA Catenet, whose Pathways are segments of ARPA-controlled networks, and whose Hosts are hosts on the networks which are part of the Catenet.
		That is, within the Network Structure of the Catenet, each of the hosts on the ARPANET (all of which are also Hosts on the internet) is MULTI-HOMED to each of the 4 Gateways via a distinct Pathway.
		We will argue that many of the problems encountered in the current Catenet configuration are a result of the failure to properly conceive internet hosts as being multi-homed, and that the lessons learned from a study of how to do multi-homing on individual packet-switching networks can be applied fairly directly.

		A catenet is a system of packet-switched communication networks interconnected via gateways [Cerf 78].
		Their measurement, the measurement of delays across member networks of a catenet, becomes important for catenet investigations.
		Packet header timestamping is also compatible with the use of test packets for catenet delay measurement.

		However, the same issues are inherent in the Catenet itself, in that misuse of the network consumes resources which are then unavailable for legitimate use.
		Thus the problem of managing use of the gateway is most critical for the VAN gateway, but applies as well to all gateways, and in fact to any shared resource.
		These users are simply the addresses of the hosts, both on the ARPANET (Catenet) side and on the Telenet side, which will be acceptable as valid source and destination addresses of packets which transit the gateway.

		With the development of public networks, in particular IPSS and PSS, and in view of the UKPO's policy of requiring users to move to these networks, it is no longer economically feasible to continue this mode of usage.
		Further, the terminal staging server for the catenet and for ARPANET would be required to suppress intermediate fields.
		It is clear that satisfactory progress requires cooperation and discussion with other parties, notably the DARPA Catenet group and groups using various public carrier services.

		DEFINITIONS: CATENET: a group of IP networks linked together IP : Internet Protocol PART 1 INTRODUCTION In the Ethernet, while all packets are broadcast, the hardware interface selects only those with either the explicit hardware broadcast address or the individual hardware address of this interface.
		If we extend the situation one step further, and assume that several conversations have taken place across the Catenet, there will be entries in the translation caches of the hosts concerned, regarding the triplets of those hosts with which the conversations took place.
		In the Catenet configuration illustrated in fig 1, this will have the effect of updating the Translation Cache within each host, whenever it receives the packet.

		While it introduces some inefficiency with CATENET based operation, it is not so much a problem unless we try to solve this minor problem.
		Short-cutting attempts such as NHRP can't solve the inefficiency issue at all even though, or, just because, it utterly destroys the CATENET model, which resulted in inelegant modifications of existing protocols, which, in turn, causes scalability problems.

		Introduction The Catenet Monitoring and Control Center (CMCC) produces a basic information gathering system for the catenet and in particular the catenet gateways.
		Background information can be found in IEN 105, "ARPA Catenet Monitoring and Control", and IEN 131, "Gateway Monitoring Protocol", describes the message formats used for communicating with the gateways.
		If a gateway is connected to a network then the matrix entry consists of two counts, being the number of interfaces to the network which are up, and down.
