Quite true. All you really need to do is to collect all the cells together and then send them all out after all cells composing an SDU have been collected. Of course, re-assembling the packet does have the advantage of being able to detect SDU corruption so as not to relay a bunch of cells for a corrupt packets. On the other hand just collecting cells and being aware of SDU boundaries is probably more efficient in terms of both memory usage and throughput. But as you point out, this is entirely an implementation decision. --- pete ------------------ Peter Schulter schulter@zk3.dec.com Digital UNIX Networking voice (603) 881-2920 Digital Equipment Corp voice (DTN) 381-2920 ZK3-03/U14 FAX (603) 881-2257 110 Spit Brook Road FAX (DTN) 381-2257 Nashua, NH 03062
