Introduction Scope This document provides design recommendations, configuration examples, and scalability test results for implementing a next generation WAN for Voice and Video Enabled IPsec VPN V3. PN based on a service provider WAN interface handoff using Ethernet at the enterprise campus and branch locations. Purpose This document provides the enterprise network manager with configuration and performance guidance to successfully implement or migrate to a WAN architecture using Ethernet as an access technology to a service provider network. The key to success is the appropriate implementation of quality of service Qo. S on a per branch or per application class per branch technique. In traditional Frame Relay, ATM, and leased line WANs, this Qo. S function is implemented at lower data rates, is limited by the number of physical interfaces or ports that can be terminated in the WAN aggregation router, or is offloaded to an interface processor. Examples of offloading per virtual circuit VC shaping and queueing are the ATM PA A3 port adapter and the virtual IP VIP interface processor with distributed Frame Relay traffic shaping.

With current Ethernet access to the service provider network commonly at 1. Mbps or 1 Gbps data rates, the data rate of the user network interface UNI interface is no longer a gating factor. Because this implementation relies heavily on per branch or per application per branch Qo. S techniques, and each instance of Qo. S can be a heavy consumer of CPU resources, the suitability of each platform is a function of the number of peers and the total bandwidth available, as well as the target data rate on a per peer basis. Currently, the access and mid range routers the Cisco 8. VXR Series platforms do not offload to an interface processor, and do not have any means of hardware assistance with implementing HCBWFQ on a per branchpeer basis. However, both the Cisco ASR 1. Cisco 7. 60. 0 offer hardware assistance for Qo. S processing. The Cisco 7. Invoices And Estimates Pro 2.0 Free Download on this page.

The ASR 1. Quantum flow Processor QFP, specifically the QFP Traffic Manager to provide hardware processing for Qo. S for all interfaces supported by the chassis. The goal, therefore, is to provide sufficient scale testing to provide conservative estimates of the bounds of the three router platform categories, as shown in Figure 1. Figure 1 Router Platform Bounds The legends on Figure 1 range from 2 5. Mbps aggregate traffic to over 1 Gbps of aggregate traffic. Intermediate hash marks are void as to scale because the performance section provides specific guidance. Finding the most cost effective hardware platform that meets or exceeds the expected offered load with the desired features enabled is a core requirement of all network designs.

The market for Ethernet is extremely large compared to other access technologies such as ATMDSL, T1E1 Serial, or Packet over SONET POS, making Ethernet chipsets and equipment comparatively low cost. Ethernet provides the flexibility to cost effectively move from 1. How To Download Magnet Links With Vuze Plus. Mbps to 1. 00 Mbps to 1 Gbps as an access link, with full duplex FDX 1. Mbps and 1 Gbps Ethernet being the norm. Carriers are more commonly using Ethernet access to their backbone network, whether via SONETSDH, MPLS, Frame Relay, or the Internet. Broadband connectivity is provided by an Ethernet handoff to either a cable modem or DSL bridge.
