If a portal computer is located at that search depth with a process that is fully connected to the broadcast channel, then the routine returns an indication of success.

In block 1108, the routine sets the expected number of holes (i.e., empty internal connections) for this process based on the received response.

In blocks 1804-1807, the routine loops attempting to send a connection edge search call internal message (i. e., connection_edge_search_call) to a randomly selected neighbor.

Examples of client/server middleware systems include remote procedure calls (“RPC”), database servers, and the common object request broker architecture (“CORBA”).

It would be desirable to have a reliable communications network that is suitable for the simultaneous sharing of information among a large number of the processes that are widely distributed.

The conference's success is guaranteed with a technical program of exceptionally high quality and diversity, including 192 judicially selected papers, 9 outstanding tutorials on hot and up-to-date topics, 2 panels on controversial issues, and a keynote address by Prof. Leonard Kleinrock - one of the founders of the field of computer networks.

Many leading international technology companies have located their advanced development centers in, Israel, including Lucent, Qualcomm, Sun Microsystems, Intel, IBM, Cisco, Microsoft, 3Com, and Bay Networks (now Nortel).

Thanks are also due to Gitta Abraham, for invaluable administrative assistance, Martin Peres, for printing the submitted papers, Kelly Donnelly and Ashutosh Dutta at Columbia University, who helped with the technical program meeting.

The choice of threshold val ues for capacity increase and decrease affects response time as well as sta bi Ii ty, and should possibly be cha nged dynamically on a per-YPC basis in order to adapt to usage patterns.

l n orde r to mainta in the cell level performance of existing VCCs, logical bandwidth modifi cat ion is don e fir st so that the occ up ie d capacity ca n be decreased as calls are te rminated.

Triggering Mechanism A ltho ugh mu ch wor k has been devoted to d esignin g a VPC overlay network with optima l capacity assignme nts, li ttl e is said about what wo uld actu ally tri gger th e reco nfi gurat ion p rocess.

IEEE Network • September/October 1996 Finally, Logothetis and Sh ioda (47] propose an activity where global capacity realloca ti o ns are made (wit hout accompany ing topology cha nges) whe n the observed call blocking probability exceeds some threshold.

The second optimization problem then finds a VPC overlay netwo rk to accom modate these routes that minimizes call setup, switching, and transmission cos ts by u sing sh orter pat hs (i.e., with fewe r V P C hops) between source -destination pairs with high traffic demands.

Dealing with dynamic topologies Yallcast Tree Protocol (YTP) (framing, forwarding, sequencing) yTCP yRTP yRMTP Etc... Getting through NAT boxes Yallcast ID Protocol (YIDP)

Member Discovery • Learn of other members to build topologies – Contact Rendezvous (initial) – Parent-side tree anycast or mesh anycast discovery messages (background activity) – Navigate tree (as-needed foreground activity) – If root, broadcast “I am root” message, inform rendezvous 0009

Root Path • Analogous to BGP AS-path • Transmitted parent to child – Each member appends itself to received root path • Discovers loops after tree change 0011

How Loops Form “Simultaneous” changes by multiple members (e.g. P and L)

Coordinated Loop Avoidance • Send “Intent to Join” along tree from joining member to new parent • Members along the path record intended change • Members along the path check for and block incompatible changes 0020

Examples of client/server middleware systems include remote procedure calls (“RFC”), database servers, and the common object request broker architecture (“CORBA”).

That is, each message must pass suitable for the simultaneous sharing of information among a large number of the processes through the root node in order to be received by all participants.

As discussed below in detail, the broadcast technique uses a hashing algorithm to select the port number order, which may result in improved performance.

In one embodiment, the distance that the edge connection request message travels is established by the portal computer to be approximately twice the estimated diameter of the broadcast channel.

If a portal computer is located at that search depth with a process that is fully connected to the broadcast channel, then the routine returns an indication of success.

I am a researcher and tenured faculty at the Max Planck Institute for Software Systems in Kajerslautern and Saarbrücken, Germany.

Before joining the Max Planck Institute, I held research or faculty positions at Cornell University, ACIRI, NTT Software Labs, Bellcore, and MITRE, and was Chief Scientist at two Silicon Valley startups.

I verified my recollection that the Yallcast paper was completed on September 30, 1999 by checking the metadata of the post script file, which states “CreationDate: Thu Sep 30 17:02:29 1999”.
