Proprietary Distributed Lane Services

Chapter 13 LANE Services

The M770 ATM Switch LECS supports a proprietary system for a distributed LES/ BUS in advance of implementing LANE version 2. This will enable not only resiliency of the ELAN but will also increase the number of clients (LECs) that can be supported per ELAN on multiple modules (up to 2,500 LECs per ELAN). This is achieved by allowing a single ELAN to be distributed over multiple LES/BUS pairs in several modules (up to 10 LES/BUS’s per ELAN). Each client connects to a single LES/BUS as normal but it could be any of the LES/BUS pairs that are supporting the ELAN.

Virtual Channel Connection (VCC) requirements

In a single ELAN that supports the proprietary Distributed LANE Service:

•each LES has a point-to-point and a point-to-multipoint VCC mesh to each of the other LESes in the ELAN.

•each BUS has a point-to-point and a point-to-multipoint VCC mesh to each of the other BUSes in the ELAN

These connections are then used to exchange information about the registered clients in the ELAN.

Setting up Distributed LANE Services

The M770 ATM Switch module sets up distributed LANE services as follows:

1When a distributed LES registers with the LECS, it is assigned a LEC id range and given the addresses of other distributed LESes on the ELAN.

2The LES will then setup a point-to-point and point-to-multipoint with the other LESes on the ELAN.

3Once connections are setup between the distributed LESes on the ELAN, the LESes will exchange information about their LECs (clients). In this way all the LESes in the ELAN will know of all other clients on the ELAN, and which LES they are attached to.

4Each LES will also discover the address of every BUS in the ELAN. This information is then used to setup a point-to-point and point-to-multipoint VCC mesh between the BUSes.

LEC Assigned for a Distributed ELAN

When the LEC starts up, it will connect to the LECS in the usual way. If there are several different possible LESes for an ELAN, then the LECS will select which one of the distributed LES addresses to assign the LEC to.
