There are cases and networks that we must ensure that traffic will reach the destination. Sensitive applications like telephony and video conferences need to reach the destination without any impact during the trip from source to the destination. However, this… Continue Reading
BGP is a routing protocol used to dynamically route packets in the correct destination. In order to accomplish that, there are some parameters to examine in order to identify which path is the best and which one should be added… Continue Reading
Forwarding engines provide the mechanisms for packet switching, forwarding and route lookup. When the packet enters the router, either it will be forwarded (to the next-hop or itself ) or dropped. In order to perform packet forwarding ( switching )… Continue Reading
Designing a stable and scalable OSPF topology requires thought and planning. In larger networks, OSPF can have an impact on the workload of the router. The number of routers in an area, the number of adjacencies and the stability of… Continue Reading
In order to create a scalable EIGRP configuration, the process before the configuration is crucial. Having the correct design before the implementation will save time in the future. Designing any L3 topology, scalability is one of the major concerns. Filtering… Continue Reading
With this article I will try to explain and simplify how a client and a server can communicate and exchange messages through web sockets, using SDP and ICE protocol. In this example I will try to explain the process of… Continue Reading
BGP does not require neighbors in the same subnet. Instead it uses TCP connection in port 179 to establish neighborship and neighbor IP is configured specifically. Also BGP doesn’t use an integer metric for route selection. Instead it uses path… Continue Reading
Policy-based Routing (PBR) is a method that a router ignores the “normal” process of forwarding packets based on the routing table and forwards it based on the configured policy. The incoming packet is captured by the policy before the router… Continue Reading
With increasingly high-speed networks, it is increasingly important to have mechanisms that keep throughput high but average queue sizes low. Congestion avoidance scheme maintains the network in a region of low delay and high throughput. Congestion Avoidance Overview CA technics… Continue Reading
Packet loss results packet re-transmission and this many times causes network congestion. In order to avoid network congestion, there are some congestion control mechanisms. Causes for network congestion are, but not limited to, fully utilized links and insufficient buffer size.There… Continue Reading
