Silver Peak gets into the SD-WAN market with Unity EdgeConnect, a new product that aims to make it easier to provision, manage, and monitor WAN connectivity for remote and branch offices.
Recently, I had to look after PBTS on Cisco ASR9K platform and faced some issues, here are some results about my tests. PBTS has the same goal as CBTS on Cisco IOS (Class-Based Tunnel selection) but for Cisco IOS-XR. It provides a tool to direct traffic into specific RSVP-TE tunnels (in the future Segment-Routing tunnels) […]
In this article we are going to see two features that improve the load-balancing in the MLPS Core. Why? In the networking when dealing with redundancy of links or paths we are facing the polarization issue. This problem happens when one of the link is congested. Let’s take the example of LAGs, if the hashing […]
Network reliability is an important measure for deployability of sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network reconverges on the new topology. Fast reaction is essential for the failed element. There are two approaches […]
In my previous post “Getting Nerdy about WAN optimisation“, I discussed some of the basics of WAN optimisation and how the Juniper WX and Riverbed Steelhead capture traffic. Now I’d like to get into the detail on how they shift traffic between networks. Once traffic enters either appliance, there are differences on how the traffic […]
