Hello Experts!<br />
<br />
We have a Linksys SLM2024 and we would like to set up some basic QOS. Our network is flat, without any VLANs. All we want to do it prioritize traffic on one port, without much negative impact on other traffic. The port we want to prioritize connects to our VOIP server. <br />
<br />
I noticed on the webgui that the SLM2024 has both COS and DSCP options. We would need to choose one of those (and not both), correct? Could you briefly explain the difference and what might work best in this case? What values do you recommend? I'm not clear on if a greater # value increases or decreases priority?<br />
<br />
Any other info on how to prioritize/improve VOIP traffic would be great also. We are using softphones so we cannot put them into their own VLAN. Any more info you may need please just let me know,

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
