Several factors may play a role, including the need for this type of bandwidth and latency factors and resilience. If a client needs a highly reliable connection with low latency and high bandwidth, a protected SONET OC3 solution is the best choice in terms of architecture.
If you are strict requirements in terms of latency and quality of OC3 might be a good choice as an alternative to Ethernet.
OC3 with the complete, end-2-end haveThe monitoring of bit errors, and is also dedicated to 100% for use. Ethernet service is not the complete end-2-end monitoring capabillity as skipped frames may come away alog's.
The equipment costs more to CPE OC3, as with Ethernet. The redundancy built into SONET / SDH can provide sub 50ms conversion easy, but the full potential of the redundancy of the harvest, offcourse you need redundant fiber to your location.
Prerequisites check
1) The data use requirements
2) Redundancy is a feature, not necessary. Therefore, the architecture was designed to request and fees.
3) Other (possibly related) options that are available to provide similar bandwidth
Optimal conditions
1) Several major hub locations (and the ring OC3) that are well connected to the rest of the network
2) A continuous band of over DS3 24×7
3) A well-integrated voice and data architecture can be performed on theseSpine and thereby reduce the PSTN and leased line cost data access.
4) The purchase of existing relationships with providers of customer premise equipment, which reduces the cost CPE
I think everyone would agree on a monetary point of view that if the cost exceeds the cost of the DS3 then with the OC-x-start circuit, it is time to think about a switch. The problem is that it is already heavily invested in hardware, DS3, OC-x and now must buy the hardwareto start a walk. In order to have the cost of hardware to the equation cost factor.
Secondly, we must keep an eye on the redundancy and latency. If the network is essential and requires no downtime, then it becomes a bit 'more complicated. 1 still does not ensure OC3 SONET, without downtime. To ensure that this idle time to a minimum of 2 OC3 circuits order is maintained. When ordering the first you want to be the primary with the lowest latency / jitterbetween two points. Their path will not be so redundant. This circuit does not touch any hardware, CO, a sterile field line through the primary use. This will mean a circuit slower and of lower quality, but the connection is a success if your primary system will be managed.
Again, that starts to affect the cost equation. If you start on the operating costs should be reminded of what it costs not to be afraidType of fault. Today's consumers do not tolerate any interruption of services of all types more so as long as their services are not available, the higher the dropout rate in the final analysis, it can be. There is a big difference between the reduction of services or customer service. If slowly, usually shrug off, unless it is always slow. The second is that it is going to start to shake.
Since most of the networks Ethernet LAN, WAN connectivity is the most efficient way to create an Internet-Ethernet (lowercase "i"Sense, building a network of smaller networks, but not necessarily the Internet (uppercase "I") to your home PC is connected.) There is no translation, as with an OC3, and there is very little effort, as with ATM solutions.
Most of the applications or voice (TDM protocol OC3) and native TDM circuit disruption of magnitude in individual 64K voice channels, usually with 56 for the payload and 8K for reporting (though used for ISDN 64K payload and reserves to separateChannels for reporting). TDM aboput great thing is that it is very reliable. If the track has ended below the nominal rate is broken and goes into alarm. Under Ethernet, the possibility of a loss of throughput, without an alarm.
Both TDM and Ethernet is possible by the carrier, but oversubscribed, drops What equipment you need information or go without warning.
The problem is that more and more applications using voice, voice over Internet (bottom"case") of the protocol, which is more effective than Ethernet. This does not mean that companies use the Internet (uppercase "I", it is your home computer connected) means that the same protocol used to provide voice over Ethernet private circuits.
VoIP is now the most important protocol for long distance.
So if you are a telecommunications company with a legacy switch architecture that can not be replaced, a great way to OC3.
If you have a voice or a data network to build –Network and local carriers are available Ethernet and Ethernet services includes the necessary level of redundancy, and Ethernet is preferred by an overwhelming majority.
A Cisco network can be fired from the same 50 ms failover to a 2-fiber SONET multi-path failover carry very low latency (1ms us a network that is available at the center and 2 ms, respectively, on serial interfaces, for which a total five milliseconds of latency). Ethernet can also point-to-multipoint be interpreted ApplicationsLayer 2 and Layer 3, with very simple means. OC3s (TDM) requires a large deployment of routers, switches, ATM or Frame Switch with large overhead costs of operation and the need to program the visibility (the ability for each site to communicate directly with another site).
Sun. An OC3 useful if you have more than 45 Mbps will be necessary, but less than 163 Mbps, Ethernet is not available or not available in a design robust enough, or if the legacy network protocols that are notbe replaced.
Price of the complete solution for requirements and specifications will be established, but Ethernet is much less expensive in general.
