Hello everyone, It has been good listening to all of you, I have learnt a lot! Just wondered if anyone has any thoughts on a problem I am working on at the moment. It involves a frame-relay network here in Australia. It consists of a hub-and-spoke topology - one central site connected to all other sites using sub-interfaces with point-to-point links. Since this network was setup, the users have been complaining of slow responses when using applications such as Telnet or Citrix. It appears that Lotus Notes replication traffic is hogging the links and causing these delays. What I am looking at doing is using frame-relay traffic shaping with traffic-rate throttling and custom queuing. I have identified the protocols and ports that need high priority, however am a bit unsure as to how to allocate the byte-count values. Apparently if the byte-count is too high then the router will service one particular queue for too long and will cause delays to other queues. I am wondering what would be a reasonable byte-count in order for this not to happen. The link that I will be testing this on initially has a CIR of 192kbps. I was going to setup three queues, one for telnet, one for citrix and one default for everything else (other traffic consists of Notes mail/replication, NT domain replication). What proportion of the bandwidth should I give to each protocol? I was thinking about 1/3 for each queue, as if a queue's reserved bandwidth is not being fully used other queues can use it....any thoughts? If anyone could give me some idea as to what byte-counts would be ok to use on this kind of link, that would be great. Any other suggestions/comments would also be good. In calculating the byte-count, I have found the average citrix frame size to be about 120bytes, and the average telnet frame size to be about 80bytes. This is my first real job involving Cisco - I am in my last year at University. Thankyou for reading all this! Hope you can help!
