The session layer of the open systems interconnection (OSI) model is responsible to set up, manage, and maintain communicative sessions in networking. Explore the OSI model and understand the session layer and its functions and protocols, and also learn about th...
Earlier communication systems tend to not fit the OSI model exactly, and do not have service abstraction, so higher layers must directly implement their service requirements in terms of the underlying protocols. This list also includes some of the main Internet standard protocols, which have largely...
The data link layer is the second lowest layer of the OSI model. This is the layer that provides the capability to transfer data from one device to another on a single network segment. For clarity, here we equate a LAN network segment with a collision domain. A strict definition of a LA...
ACLs in NVOS Linux classify and control packets to and from the switch, asserting policies at layers 3 and 4 of the OSI model by inspecting packet headers according to a list of rules. The rules inspect or operate on packets at several points (chains) in the life of the packet throug...
ACLs normally are applied at layers 3 and 4 of the OSI model, but some vendors (Cisco and Extreme, for example) offer layer 2 ACLs, and others (Alteon/Nortel, for example) offer ACLs at layers 5 and above. ACLs, in coordination with VLANs, QoS, and firewalls, are powerful tools for...
It implements an ACID-compliant object graph model with user-defined indexes and map-reduce views. It also implements a master / slave replication scheme for redundancy and horizontal read scaling. Querying the graph is accomplished via a number of Lisp methods or via a Prolog-like query ...
In the first week of this course, we will cover the basics of computer networking. We will learn about the TCP/IP and OSI networking models and how the network layers work together. We'll also cover the basics of networking devices such as cables, hubs and switches, routers, servers and...

A switch operates at the data link layer (Layer 2) of the OSI model. It is an intelligent device that examines the MAC (Media Access Control) addresses of data packets to determine where to forward them. Switches create a dedicated, point-to-point connection between the sender and recipient...
