NettetIn the Linux kernel, packet capture using netfilter is done by attaching hooks. Hooks can be specified in different locations in the path followed by a kernel network packet, as … NettetIEEE 802.15.4 is a stack of protocols for organizing Low-Rate Wireless Personal Area Networks. The stack is composed of three main parts: IEEE 802.15.4 layer; We have chosen to use plain Berkeley socket API, the generic Linux networking stack to transfer IEEE 802.15.4 data messages and a special protocol over netlink for …

NettetNetfilter’s flowtable infrastructure. This documentation describes the Netfilter flowtable infrastructure which allows you to define a fastpath through the flowtable datapath. This infrastructure also provides hardware offload support. The flowtable supports for the layer 3 IPv4 and IPv6 and the layer 4 TCP and UDP protocols. NettetAbove we read merely about the theory of networking, about the basic ideas, about communication protocols and standards. Now, let us see, how all of this is being …

The sending process (the upper layer calls the lower layer) is usually a direct call (because there is no uncertainty, for example, TCP knows that there is a certain IP …

NettetThis paper presents measurement and insights for Linux kernel network stack performance for 100Gbps access link bandwidths. Our study reveals that such high bandwidth links, coupled with relatively stagnant technology trends for other host resources (e.g., CPU speeds and capacity, cache sizes, NIC buffer sizes, etc.), mark a …
Nettet7. jul. 2016 · The Linux TCP stack has some extremely useful non-trivial support for things like RFC4821 with the sys.net.ipv4.tcp_mtu_probing sysctl. Support for this is critical when a user is behind an ICMP black hole. Read more in this blog posts about PMTU.
