Considerable research has been devoted to the formulation and solution of problems involving flow within connected networks. Independent of these surveys, an extensive body of knowledge has accumulated on the subject of queues, particularly in regard to stochastic flow through single-node servicing facilities. This text combines studies of connected networks with those of stochastic flow, providing a basis for understanding the general behavior and operation of communication networks in realistic situations.Author Leonard Kleinrock of the Computer Science Department at UCLA created the basic principle of packet switching, the technology underpinning the Internet. In this text, he develops a queuing theory model of communications nets. Its networks are channel-capacity limited; consequently, the measure of performance is taken to be the average delay encountered by a message in passing through the net. Topics include questions pertaining to optimal channel capacity assignment, effect of priority and other queue disciplines, choice of routine procedure, fixed-cost restraint, and design of topological structures. Many separate facets are brought into focus in the concluding discussion of the simulation of communication nets, and six appendices offer valuable supplementary information.

EDIT: *NOT* great for aggressive chewers!!! ☹️
Style: Two pack, Style: Two pack
UPDATE (previous 5⭐️): Yep. Things changed!! I take it alllll back!😩🤦🏼♀️ Here we are, just shy of a month and they’re both toast!!! The pics might not look like a big deal, but we tossed the orange one after finding the chewed off bits in his poop. The only reason I was able to take a pic of this blue one is because we couldn’t find it until now. However, the orange one looked the same when we tossed it, so I’m sure we’ll be finding blue bits in his poop. Not a fan of ANY chew toy he can actually end up eating!! I have PTSD from our last fur baby that suddenly decided he liked to swallow socks @ 11yo & ended up needing emergency surgery to the tune of ~$5K!🥴
These are crazy!! They’re super hard plastic, almost like glass. I wasn’t expecting that! My hubs was joking they’re for seggy time, not dogs! 🫣😂 We got a puppy in April that is an aggressive chewer. We’ve both had dogs most of our lives, but this aggressive chewing is new to both of us. Lil dude has chewed through a ton of other toys advertised for aggressive chewers- a few within just hours!! It’s wild!! We’re not used to it, but he loves his toys, so we keep trying to get him ones that will last! 😅
We only got this 2-pk yesterday morning, but he’s been obsessed & so far, so good! With how hard they are, I’m feeling very confident they’ll last longer than any other toy we’ve bought him!!
I will update if anything changes!
