Art and Tech is madness
by Kasper Adel 06 Sep '19

06 Sep '19

In SPRING a time when segment and routing had no mismatch, a time when isis and ospf ate a forbidden encap, all they had to do was forward bgp like its hot, but crazy flapping doesnt leave any real LDP without some real FSM check, My dynamic unnumbered neighbor. Suddenly, Out of order, an AS is overridden, we see frames dropping, we sniff a bit and it turns out, sfps are burning, we are in a place right now where ping and pong are jittery, their latency is tested, they cant strengthen their icmp bond with a warm bfd message, how can they keep everyone in ACK, safe from teardown and dampening, with this kind of ixp relationship??! but oh admin, we know forwarding works in its own mysterious ways. We are left with two non rfc compliant scavengers, bastard 802.1ah fools in a leaky yet shaped, buffer display of some runts and nimbles, and a giant too. They start their life of a packet, leaving one interface to a neighbor, from an adjacency to a peer, an endless loop, its a prefix hijack, but as they move from one stack to another, finding their way through a tunnel of memory failures and RMAs, one hell of an LSP ride, through firewall horrors and MTU mismatches, leaving behind, a sea of syslog messages and snmp alarms. Anyway, Their ttl expired and one funny access list abruptly denies them life, sending them to Null0, where they can be peacefully discarded. Thats what tech does to yeh

Cat 5 hurricane -- How are the Bahamas doing?
by Sean Donelan 06 Sep '19

06 Sep '19

It is too early for damage assessments. BTC, local Bahama telecommunications company, is reporting widespread power outages, and intermittent mobile and wireline telephone service. The Abaco Islands in northern Bahamas seem to be taking the worst of it. Network measurements sites are reporting less than 6% reachability in Hope Town, Bahamas. Other parts of Bahamas have less than 50% reachability.

Spam due to new ARIN allocation
by Tim Burke 05 Sep '19

05 Sep '19

We recently received a new ASN from ARIN - you know what that means... the sales vultures come out to play! So far, it has resulted in spam from Cogent (which is, of course, to be expected), and now another company called "CapCon Networks" - http://www.capconnetworks.com. As far as I am aware, this practice is against ARIN's Terms of Use. Is it worth reporting to ARIN, or perhaps it's worth creating a List of People To Never Do Business With™, complete with these jokers, and other vultures that engage in similar tactics? Regards, Tim Burke tim(a)burke.us

The e2e paper is by far one of the closest things we have to network canon and its reasoning is exceptionally simple and compelling. Yet, these are arguments, not laws. Even the original authors have revisited and questioned the original ideas. The paper also says something about needing a great deal of system implementation detail to intelligently make the choice of where to place functions. I like pointing that out, because it seems people often miss this part in the paper where the only form of the word intelligence is ever used in the paper. Note, I'm not agreeing or disagreeing with any particular position about multihoming in this thread, just trying to argue that the e2e paper is a lot more nuanced than is often presented in debates especially since it has often been used to support opposing views. :-) John

Greetings, I am looking for some suggestions on alternatives to mx204. Any recommendations on something more affordable which can handle full routing tables from two providers? Prefer Juniper but happy to look alternatives. Min 6-8 10G ports are required 1G support required Thanks in advance! Mehmet -- Mehmet +1-424-298-1903

As you give no reference, let's rely on wikipedia https://en.wikipedia.org/wiki/Recursive_Internetwork_Architecture -------------------------------------------------------- Yes, my apologies for no reference. Further, I have no URL to point to as I read the book. (actual book; no e-something) Here's something: http://pouzinsociety.org Like the book, in the Wikipedia article you have to get through or skip the first part. In the book, that's the first 5 or so chapters. He just describes why, in his opinion, previous things have failed and the way he does it turns a lot of folks off. Likewise, I skipped the last 1-2 chapters. So in the Wikipedia article skip to the Introduction" section. A couple more things: --------------- E2E (end-to-end principle) is not relevant IPv6 is/was a waste of time The RINA's fundamental principles are that computer networking is just Inter-Process Communication or IPC, and that layering should be done based on scope/scale, with a single recurring set of protocols, rather than function, with specialized protocols. --------------- ------------ more from Wikipedia ---------------- The IPC model of RINA concretizes distributed applications in Distributed Application Facilities or DAFs, as illustrated in Figure 2. A DAF is composed of two or more Distributed Application or DAPs, which collaborate to perform a task. These DAPs communicate using a single application protocol called Common Distributed Application Protocol or CDAP, which enables two DAPs to exchange structured data in the form of objects. All of the DAP's externally visible information is represented by objects and structured in a Resource Information Base or RIB, which provides a naming schema and a logical organization to the objects known by the DAP (for example a naming tree). CDAP allows the DAPs to perform six remote operations on the peer's objects: create, delete, read, write, start and stop. In order to exchange information, DAPs need an underlying facility that provides communication services to them. This facility is another DAF whose task is to provide and manage Inter Process Communication services over a certain scope, and is called a Distributed IPC Facility or DIF. A DIF can be thought of as a layer, and enables a DAP to allocate flows to one or more DAPs, by just providing the names of the targeted DAPs and the characteristics required for the flow such as bounds on data loss and delay, in-order delivery of data, reliability, etc. DIFs, being DAFs, can in turn use other underlying DIFs themselves. This is the recursion of the RINA. scott and restrict scope only for multihoming. Then, it is true that: > 1972. Multi-homing not supported by the ARPANET. which means current specifications do not support multihoming very well. but, the statement > The solution was obvious: as in operating systems, a logical address > space naming the nodes (hosts and routers) was required on top of the > physical interface address space. is wrong, because it is enough to let transport layer identify connections based on a set of physical interface addresses of all the interfaces, which is what draft-ohta-e2e-multihoming-* proposes. That is, he misunderstand restrictions by the current specification something inevitably required by layering. > It tosses all this on its head. If you have some text of RINA denying the E2E argument, quote it with URLs please. Masataka Ohta
