RE: backing up to tftp server

VoIP
Hello everybody, I need to use a network for doing Voip and I have the RTT history for the network. I can't change the network (I do not administer it , and I can't change anything). The routers in the network don't do particular queuing(I think they all do FIFO, but it is possible some of them will do RED). Do you know of some table that gives me the correspondence MOS(subjective Quality of voice) and network condition (Medium RTT,percent of packet loss, maximum RTT, variance of end to end delay,.) or an indication of what range should the parameter of the network condition should have to do a decent or good VoIP conversation. -- Best regards, mamo mailto:[EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: SPAN port on Cat5500-Performance?

You can use ps -c to check switch performance.

Re: CSMA/CD : full duplex
Actually CSMA/CD is still required. When communicating through a switch, the TX (towards the switch) is guaranteed the full bandwidth towards the switch. However the inbound (RX from the switch) may be carrying traffic from more than one originating host. As such, collisions may still occur if more than on of these hosts tries to talk to the same destination at the same time. A basic switch (without VLANS and fancy Layer 3 functionality) creates bandwidth domains but NOT broadcast domains. As such it will still flood broadcasts and multicasts to all ports - again creating opportunity for collisions that require CSMA/CD arbitration. Full duplex increases throughput as less traffic is forwarded to end devices (cuts out unicasts not addressed to the attached devices) but does not guarantee collisionless connectivity. CSMA/CD is required to handle the collisions that do occur. Keith ""Joe Martin"" [EMAIL PROTECTED] wrote in message 8fbq4s$80t$[EMAIL PROTECTED]">news:8fbq4s$80t$[EMAIL PROTECTED]... Full duplex transmission requires a point to point connection between two devices. This is achieved using a switch. Since the connection is between two and only two devices at a time, this allows them to transmit and receive at the same time. Thus a collision would never occur and CSMA/CD is unnecessary. JOE CCNP, CCDP, and a few other things... "Dan West" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Sorry to ask such a simple question--but the CCNA book is still unclear as to what's going on. Half-duplex ethernet uses CSMA/CD for arbitration on the link. Does full duplex use it as well for arbitration? The book makes it sound like if you are running full-duplex that the CSMA/CD is not necessary. It mentions half-duplex looping a duplicate frame onto the recieve wire from the transmit wire. Thanks. __ Do You Yahoo!? Send instant messages get email alerts with Yahoo!

Load-balancing in a triangle ?
Hello, Could anybody comment the following problem: -I have three Cisco routers, (POPA, POPB and CUSTOMER - exact models are not important). ---uplink_1[POPA]---2Mbps-[POPB]uplink_2 ! ! ! ! +---512k---[CUSTOMER]---512k---+ ! ---+--- customer network - A customer router (CUSTOMER) is connected symmetrically both to POPA and POPB. Each customer link is 512k, and the main purpose for two links was to have backup connection (if link between POPA and CUSTOMER goes down, traffic from POPA will go POPA-POPB-CUSTOMER, and vice versa). It works as a backup. - Currently RIPv2 is used between POPA, POPB and CUSTOMER, but it can be changed to any other protocol. PROBLEM DESCRIPTION: Currently all customer traffic that comes from uplink#1 (via POPA) will flow ONLY through link POPA-CUSTOMER, even if this link is highly loaded already. The same is true about traffic coming from uplink_2: it will use only link POPB-CUSTOMER. DESIRED GOAL: Is it possible to implement some kind of load-balancing between two customer links ? That is, even if all incoming traffic for customer network comes to POPA via uplink_1, I'd like both customer 512k-links to be loaded equally (half of the traffic must flow in a path POPA-POPB-CUSTOMER). The same should be true for traffic coming via uplink_2: it must also be balanced between two 512k links. WBR, Alex PS. It is supposed that 2Mbps link between POPA and POPB may be upgraded easily as needed, so its load should not be taken into account. ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Fibre Optic - 100FX
This has to do with the "bit budget" constraint in the CSMA/CD protocol. The collision detection part of the CSMA/CD protocol only works while ethernet devices are transmitting data. If any collision happens after transmission then that collision is termed a "late collision" and will not cause ethernet itself to recover. Higher layer protocols will have to retransmit. So, in order to detect collisions the smallest ethernet packet (64 bytes) factored in with the speed and distance of the link determine the maximum cable distance allowable for hosts to still effectively detect collisions while transmitting and CSMA/CD to operate correctly. This information also addresses a recent post by Dan West regarding CSMA/CD. When using full duplex ethernet, transmitting and recieving takes place on seperate physical wires. This means that the CSMA/CD protocol is not needed or used on full duplex connections. There was a reply to that post stating that CSMA/CD is still required when using full duplex ethernet due to multiple incoming frames from a switch to pc. This is incorrect. If a switch has multiple frames destined for one physical port it will transmit one at a time based on buffering mechanisms explained in detail by Howard Berkowitz in past posts to the list. However these buffering mechanisms are internal to the switch and are not in any way related to CSMA/CD. Full duplex ethernet is a collision free environment with no CSMA/CD protocol which is why the distance limitation is much greater than half duplex which must conform to CSMA/CD restraints. -Mike Cohen -Original Message- From: Tan Choh Koon [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 10, 2000 8:31 AM To: CiscoGroupStudy Subject: Fibre Optic - 100FX Hi all, Do anyone know the theory why 100Mbps Hub with Multimode fiber link, the distance is 412 m for Half Duplex and 2000 meter for Full Duplex mode ?? ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

I know that 802.5 is Token Ring. What is 802.2? Is it ethernet? -- Oscar Rau [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
