- Consider the following implementation of a Multiprotocol router
- installed over the cell relay network
-
- Assume again that some low cost clone-able cell relay hubs are being
- deployed user wide, having the characteristic that the line
- card format is well known, publicly defined, and supported by a
- third party industry.
-
- A router software vendor decides to deploy a distributed multi-protocol
- router for user networks, which adds onto the user's existing
- cell relay network. The plan is to put the router software in add-on
- processor cards to be placed strategically in various nodes, as desired
- by the user.
-
- Each router card essentially accepts virtual path data across the
- line card bus, and emits virtual path data over the same bus. (The
- hub system puts all cell relay functions on a switching motherboard).
- The router processors have no external connection, being simply embedded
- processors.
-
- The job of the router cards are:
-
- 1) Search out seek all other router cards within the network, building
- a directed graph which allows it to be addressed by a single VCI globally
- known to all other router cards.
-
- 2) Build new path to each of the directed graphs already in operation
- by the other router cards, using their allocated VCI.
-
- 3) Using a globally known address resolution VCI (for ARP), build a
- directed graph out to each of the desktops within its operating region.
-
- 4) Using the ARP procedures, having vendor proprietary inter-router
- control codes, maintaining host address table management independent of
- the cell relay administration procedure, having some extra SNMP management
- links, and using its ability to build out VCI as needed to its desktops,
- the router cards then begins to function as a distributed application,
- providing all the traditional routing functions known and accepted by
- the user.
-
- Bring on the flame throwers:
-
- Why isn't this the way cell-relay and router technology supposed to mesh?
- Doesn't this system offer total routing, using a small base of VCI?
- Doesn't this system encourage specialized routing software companies?
- Wouldn't the voice applications have this same independence and layering?
- Aren't we building a new third party applications industry, both hardware
- and software, by opening up the hub line card and VCI control layer?
